This blackjack calculator totals the entered cards, handles flexible ace values and works out a settled main-hand result under the stated rules. Use it to distinguish a natural blackjack from another twenty-one and to separate profit from the total amount returned.
Choose hand totals only, compare completed main hands, or calculate a permitted late-surrender settlement. The worked examples explain each mode. All money amounts are in Canadian dollars; the example stakes are calculation inputs, not recommendations.
Calculate a hand total or settlement
Enter ranks in dealt order, separated by commas or spaces. A is an ace, T or 10 is a ten, and J, Q and K each count as ten. Compare mode assumes ordinary 1:1 main-hand wins, the selected natural payout and full liability of the entered stake on a full loss.
Late surrender assumes an original, non-natural two-card player hand, a completed dealer blackjack check and permission to surrender. It uses an even number of cents so half the stake is exact. Original-bet-only refunds, early surrender, side wagers and special variants need their own settlement rules.
Which calculation mode fits?
Hand totals only
Check aces, hard totals, soft totals and busts. The dealer entry may be blank. Stake and payout settings are unused.
Compare completed hands
Calculate the entered main-hand outcome once the required cards and rules are known. Include the full stake on that hand.
Permitted late surrender
Check a half-stake settlement after the dealer blackjack check has cleared. The tool does not establish whether surrender was offered.
Changing an input replaces the previous result with a reminder to calculate again. Press Calculate after entering the intended values. Reset restores the illustrative soft-eighteen versus hard-seventeen example and its $10 stake.
Card values and flexible aces
Number cards count at their number, while tens and face cards count as ten. The calculator first counts every ace as one, then adds ten if doing so keeps the total at twenty-one or below. That makes one ace count as eleven when possible.
Only one ace can be promoted this way without exceeding twenty-one: two aces both counted as eleven would already total twenty-two. The other aces remain one. A soft hand has an ace currently counted as eleven; a hard hand does not.
Our card values guide explains the ranks, while the hard and soft hands guide follows the same distinction through extra cards. A soft total can change to a hard total without the hand busting.
Hand-total examples to try
| Cards | Total | Classification | Reason |
|---|---|---|---|
| A,7 | 18 | Soft | Ace counts as eleven; alternative total is eight |
| A,A,9 | 21 | Soft, three-card 21 | One ace is eleven and the other is one |
| A,7,10 | 18 | Hard | The ace must fall to one |
| A,A,9,10 | 21 | Hard | Both aces count as one |
| K,Q,2 | 22 | Bust | The lowest possible total exceeds twenty-one |
| A,K | 21 | Two-card natural if original hand | Split origin changes its settlement classification |
The three-card twenty-one is not a natural merely because it contains an ace. The calculator reports the total and also preserves the information needed for the payout classification.
A natural is different from ordinary twenty-one
A qualifying original two-card ace plus ten-value card is a natural blackjack in this model. An ordinary winning hand pays 1:1; a natural uses the selected 3:2 or 6:5 rate. Those are different settlement categories.
Mark the split-origin box when the player hand came from splitting. A split ace receiving a king totals twenty-one but is treated here as ordinary twenty-one, not a new natural. MGM GameSense makes the same distinction in its explanation of split-hand payments.
A dealer natural beats an ordinary player twenty-one. Two qualifying naturals push in this model. A player natural beats a dealer’s non-natural twenty-one and uses the selected natural payout.
Check the actual game rules before interpreting a result as an account entitlement. The calculator applies its stated model, including full entered-stake liability where a full loss applies.
Try the same twenty-one with different origins
Start with Compare completed main hands, a $10 stake, 3:2 natural payment and the split-origin box clear. Enter A,K for the player and 7,4,K for the dealer. The player has a natural while the dealer has a three-card twenty-one, so the player earns $15 and receives $25 altogether.
Now change only the split-origin box. The player’s A,K becomes an ordinary split-origin twenty-one. Against that same dealer twenty-one, the result is a push with the $10 stake returned. The card total stayed at twenty-one while its payment category changed.
Keep split origin selected and change the dealer to 10,9. The player now wins ordinarily, earning $10 and receiving $20. Selecting 3:2 in the natural-payment field does not force a natural payout onto a hand that does not qualify.
Finally, clear split origin, enter 7,4,K for the player and A,K for the dealer. The dealer natural beats the player’s ordinary twenty-one, producing a full loss under the stated liability model. These examples explain why comparing only final totals misses information needed for settlement.
Profit, loss and total return
On a $10 ordinary win, the hand earns $10 profit and returns $20 including the original stake. A push returns $10 and earns nothing. A full loss returns zero and loses the entered $10.
A $10 natural at 3:2 earns $15 and returns $25. At 6:5 it earns $12 and returns $22. The calculator does not count the returned original stake as another part of profit.
The payouts guide works through these amounts in detail. For a ratio-only calculation without entering cards, use the payout calculator in the Tools hub.
These are main-hand returns. They are separate from a casino withdrawal, a bank payment or a processing fee. The withdrawals guide explains those later account stages.
Completed-hand settlement examples
The following examples use a $10 fully liable stake and ordinary S17 main-hand rules unless otherwise stated. They are selected calculations, not probabilities or recommended hand actions.
| Player cards | Dealer cards | Result | Net | Total returned |
|---|---|---|---|---|
| 10,9 | 10,8 | Ordinary win | +$10 | $20 |
| 10,8 | 9,9 | Push | $0 | $10 |
| 10,6 | 10,7 | Ordinary loss | −$10 | $0 |
| A,K | 10,9 | Natural at 3:2 | +$15 | $25 |
| 7,4,K | A,Q | Dealer natural beats ordinary 21 | −$10 | $0 |
| K,Q,2 | 10,6,K | Player bust loses despite dealer bust | −$10 | $0 |
The last row matters because the player can lose by busting before the dealer finishes. Comparing only the two final numbers and declaring a tie because both exceed twenty-one would produce the wrong ordinary settlement.
When the dealer hand is incomplete
For an ordinary comparison, the dealer must have reached a stopping point under the selected rule. A non-busted total below seventeen still needs a card. Under H17, a soft seventeen also needs a card; under S17, the dealer stands on it.
For example, ace-six is soft seventeen. Entering it as a finished dealer hand against an ordinary player eighteen is incomplete under H17. Ace-six-ten becomes hard seventeen and can stop under that rule.
Enter dealer cards in dealt order. The calculator rejects extra cards after a stopping total under the selected rule. Ten-seven-two, for instance, includes an extra draw after hard seventeen, so simply comparing the final nineteen would hide an inconsistent entry.
A player bust or qualifying natural can resolve before the dealer needs to draw further. The calculator handles those outcomes before requiring a completed ordinary dealer total. The dealer rules guide explains the sequence and terminology.
Check card order as well as the final total
Enter A,6,10 for the dealer under H17. The first two cards make soft seventeen, on which this rule requires a hit. The ten then makes the ace fall to one, leaving hard seventeen. That entered sequence can stop.
Switch the dealer rule to S17 without changing those cards. The first two cards already required a stand, so the additional ten is inconsistent with the selected rule. The calculator flags the sequence rather than accepting the final seventeen in isolation.
Ten-six-ten is a different example. Its first two cards total sixteen, so another card is required under either supported rule. The next ten busts the dealer. A non-busted ordinary player hand wins at 1:1; a player hand that also busted still loses.
These checks concern the entered stopping sequence. They do not verify a real game’s shuffle, card supply, account history or whether the original entry was transcribed correctly. Keep the actual recorded cards alongside the calculation when investigating a discrepancy.
Settlement modes also reject player cards added after a bust or twenty-one. Totals-only mode remains an arithmetic check of the entered ranks rather than a reconstruction of a completed deal.
Doubles and split hands need the actual stake
If a $10 initial bet was fully doubled, enter $20 as the total stake on that hand. An ordinary win then earns $20 and returns $40. A loss costs $20. Entering only the initial $10 would understate both the exposure and the settlement.
Calculate each split hand separately. If two $10 split hands finish with one ordinary win and one full loss, their returns are $20 and zero against $20 committed. The combined round breaks even even though one hand won.
Our double down guide and split guide explain the added stakes. The exposure worksheet can total equal-stake split hands and full doubles before their separate settlements are combined.
This calculator assumes the full entered stake is liable when it reports a full loss. Original-bet-only refunds and special late-dealer-blackjack protections require their own rule-specific accounting. Do not combine different refund models inside one ordinary example.
Combine two separately settled split hands
Consider an invented round that started with $10, split into two $10 hands and added a full $10 double to the first hand. Total commitment is $30. The first hand therefore has a $20 stake, while the second has $10.
If the first hand finishes 6,5,K against dealer 10,9, enter its $20 stake and mark split origin. It wins ordinarily, earning $20 profit with $40 returned. The three-card twenty-one does not receive a natural payout.
If the second hand finishes 10,6 against the same dealer nineteen, its $10 stake loses and returns nothing. Combining the two hands gives $40 returned against $30 committed: a $10 net round profit.
Do not calculate both hands using the original $10 stake or count the winning hand’s $40 return as $40 profit. Those shortcuts would omit the double or count original money as winnings. One row per hand keeps the calculation auditable.
Calculating permitted late surrender
Choose the late-surrender mode only when the game permits it and the dealer blackjack check has cleared. Enter the original non-natural two-card player hand and the dealer’s original two cards for that check.
A $10 permitted half-stake surrender returns $5 and produces a $5 loss. The returned amount is not profit. The calculator rejects a dealer natural, a split-origin player hand or a player hand that does not fit the stated two-card surrender model.
To avoid choosing an unknown half-cent convention, surrender mode requires an even number of cents. A $10.01 stake cannot be halved into whole cents; the calculator asks for an exact-half input rather than inventing the table’s rounding rule.
Early surrender is a different rule and is outside this mode. The surrender guide explains why timing and availability must be checked before applying the half-stake arithmetic.
Decimals, rounding and supported inputs
Enter money using digits and no more than two decimal places. The calculator accepts positive stakes up to one million Canadian dollars for arithmetic testing. That input ceiling is not a suggested amount or a statement of any table’s maximum.
Natural-blackjack profit is rounded to the nearest cent for the illustration, with a positive half-cent rounded up. A $7.50 natural at 3:2 earns exactly $11.25 and returns $18.75, while a one-cent input can create a fractional-cent calculation. Actual denominations and payout rules decide what can be wagered and paid.
Totals-only mode ignores stake and payout settings, so those controls are disabled there. Dealer cards can be blank in that mode. A one-card entry can be totalled, but the output identifies it as a one-card entry rather than a completed hand.
Up to twenty-one ranks can be entered for each hand. The calculator does not track suits, remaining deck inventory or whether the entered ranks were available in a real shoe. It checks rank values and the stated settlement conditions.
Enter individual ranks rather than a finished total. For eighteen made from a ten and an eight, enter 10,8 rather than 18. Use A for an ace rather than entering 11, because its usable value depends on the other cards. Unknown ranks, a missing required hand and incompatible settlement entries produce an error and clear the previous output. Correct the message, then calculate again so an earlier valid answer is not mistaken for a result using the new inputs.
Totals and settlements are different from decisions
Knowing that a hand is soft eighteen does not, by itself, tell you which action fits every rule set. The dealer upcard and permitted actions matter. A calculation of a completed result also cannot prove that an earlier hit, stand, double or split was the better choice.
Use the basic strategy guide and cheat sheet for the site’s stated four- or eight-deck S17 reference. Keep their action key and assumptions with the chart.
The calculator’s S17/H17 control checks dealer stopping behaviour; it does not convert that linked S17 chart into an H17 playing reference. Different chart assumptions need to remain visible rather than being silently transferred between tools.
The systems versus basic strategy comparison also separates the starting amount from the hand action. Changing the stake cannot answer a decision that depends on the current cards.
A resolved result is not a winning probability
Entering known cards lets the calculator add their values and apply the stated settlement rule. It does not reveal the next card, reconstruct an unknown shoe or calculate the chance that the entered hand would occur.
OLG PlaySmart explains that cards removed from a shoe change its composition. A list of recent wins and losses does not fully describe that information. Neither the final total nor a displayed return supplies an exact house edge for a real table.
The odds and house edge guide explains probability and expected return. A winning worked example can demonstrate correct arithmetic without showing how often that result happens or how an entire session is likely to end.
Which settlements need another model?
Insurance and side wagers have their own results. Keep them outside this main-hand stake and settle them separately. A main-hand loss can occur alongside a winning side wager, and the reverse can happen too.
Variants with special twenty-one bonuses, dealer-push rules, different decks or unusual split payments can change settlement. The calculator’s ordinary main-hand result should not be treated as a complete analysis of every game carrying the blackjack name.
Similarly, a payout result does not establish eligibility under account or promotional conditions. The bonus terms guide explains why restricted balances and game rules answer different questions.
A partial refund is a separate settlement
Suppose $20 was committed but a rule-specific outcome returns $10 rather than losing the entire amount. The net loss is $10. That is not the calculator’s full-loss result for a fully liable $20 stake.
Do not change the entered commitment to $10 merely to imitate that net figure. Doing so would hide the actual $20 exposure and the $10 returned. Keep both amounts in a separate refund ledger and use the game’s particular rule to explain the return.
The same distinction applies when an account reverses a wager or corrects a recorded settlement. A later adjustment is not another natural or ordinary win. This calculator handles the listed hand outcomes; a broader reconciliation must retain any additional adjustment explicitly.
Keep the inputs with the result
Record the card ranks in order, stake on this hand, natural payout, dealer stopping rule, split-origin setting and calculation mode. Without those inputs, a copied result can be mistaken for a different settlement.
For a split round, keep one row per hand and add the net results afterward. Record any independent wager separately. If the combined balance appears wrong, check for an omitted additional stake or a returned original stake counted as profit.
The Tools hub includes a session balance calculator for reconciling opening and closing money with deposits, withdrawals and outside fees. Hand settlement is one part of that broader record.
Keep a spending and time boundary separate from a desire to obtain a particular result. The gambling help page provides practical support information when those boundaries become difficult to follow.

Common blackjack calculator questions
The ace uses one when counting it as eleven would push the hand over twenty-one. A,7 is soft eighteen, while A,7,10 is hard eighteen. With multiple aces, the calculator starts with each as one and adds ten only when that leaves a valid total. A natural requires an original two-card ace plus a ten-value card in this model. A three-card twenty-one is an ordinary hand. Mark split origin for a hand created by splitting: A,K then totals twenty-one but does not qualify for the selected natural-blackjack payment. Total returned includes any original stake given back. A $10 ordinary win earns $10 profit and returns $20. A $10 natural at 3:2 earns $15 and returns $25. A push returns the $10 stake with zero profit; a full loss returns nothing. Yes. Under the ordinary rules used here, the player loses on busting even if the dealer also exceeds twenty-one. The calculator does not turn two busts into a push or compare them by which total is lower. Special variants require their own settlement model. H17 requires another card on soft seventeen, while S17 requires a stand. Both stop on hard seventeen. Enter the dealer cards in dealt order: A,6,10 is a valid H17 sequence ending on hard seventeen, but the extra ten conflicts with S17 because A,6 already required a stand. Enter the entire stake on the single hand being settled, including a double. An initial $10 hand doubled by another $10 uses $20. Calculate each split hand separately and mark split origin. Add their returns and commitments afterward to obtain the round’s combined net result. No. It assumes permission, an original non-natural two-card hand and a completed dealer blackjack check. It rejects a dealer natural and split-origin hands. A $10 accepted surrender returns $5 and loses $5. The mode requires an even number of cents so the half-stake amount is exact. It rounds the illustrative natural profit to the nearest cent, rounding a positive half-cent up. A $7.50 natural at 3:2 earns exactly $11.25 and returns $18.75. Actual table denominations and payout rules determine payable amounts; an input accepted for arithmetic testing does not establish an available stake. No. It totals entered ranks and applies its stated settlement model. It does not choose hit, stand, double or split, calculate the next-card probability or verify a real account transaction. Use the separate rule-matched strategy references for hand decisions, and calculate again after changing an input.Why does an ace change from eleven to one?
