Keno Payout Calculator: Stake, Multiplier, Profit and Expected Value
Choose a prize table, enter how many numbers you picked and matched, and set your stake to calculate the payout and net profit. For another game, use manual mode with its total-return multiplier and any gross prize cap. Each calculation covers one selection in one draw.
Calculate Keno payout
Choose a payout source below. A lottery preset loads its base-game format and looks up the multiplier as you change picks and matches. Manual mode lets you enter your own multiplier. For complete reference schedules, see the Keno payout charts.
Changing the source loads an example. Enter your own ticket settings after selecting it.
Payout results
Enter a payout source and your selection.
Check the selected game's prize rules before using a scheduled payout as a final award.
One-outcome EV model and break-even probability
This model pays only for the selected hit count and treats all other results as zero payouts. It is not the expected return of the full game.
For the expected return across every paying result, use the RTP calculator.
Reverse target payout
Enter a target gross payout in the form. Manual mode solves the multiplier and stake algebraically. A lottery preset keeps its multiplier fixed and finds the lowest allowed wager whose scheduled prize reaches or exceeds that target.
A prize target does not increase the chance of matching numbers.
Stake payout matrix
Compare the payout and net result for the same exact match count at different stakes. A fixed prize cap can make the effective multiplier smaller at higher stakes.

Worked payout examples
| Game and result | Stake | Prize per $1 | Gross payout | Net profit / loss |
|---|---|---|---|---|
| Ohio: 5 matched from 6 picks | $5 | $57 | $285 | $280 |
| Connecticut: 5 matched from 6 picks | $5 | $50 | $250 | $245 |
| Ohio: 0 matched from 10 picks | $1 | $5 | $5 | $4 |
| Connecticut: 10 matched from 10 picks | $5 | $100,000 | $100,000 after cap | $99,995 |
| Ohio: 2 matched from 6 picks | $5 | $0 | $0 | −$5 |
Partial matches pay only when they appear in the selected schedule. Zero matches can also pay, as the Ohio 10-pick example shows. The calculator looks up the exact match count rather than adding all lower prize tiers.
How Keno payout is calculated
For a total-return multiplier, multiply the base stake by the multiplier for the exact match count. Apply any fixed gross prize cap, then subtract the stake to find the net result:
Uncapped payout = stake × multiplier
Gross payout = min(uncapped payout, gross prize cap)
Net profit or loss = gross payout − stake
If no fixed cap applies, gross payout equals the uncapped amount. A stake of 10 with a 5× total-return multiplier returns 50 in total: 40 profit plus the original stake. A 0× line returns nothing, so the net result is −10.
In manual mode, use the same currency for stake, cap and target payout. If a game quotes winnings “to 1” and returns the stake separately, convert to a total-return multiplier before entering it. A net-profit limit also needs conversion to a gross payout limit by adding the stake; update it whenever the stake changes.
Prize caps and shared prizes
Connecticut's base-game prize is capped at $100,000. For example, a $5 wager matching 10 of 10 would produce $500,000 by multiplication alone, but the calculator limits the gross prize to $100,000.
Ohio's 8-, 9- and 10-spot top prizes have separate $2 million shared prize pools per draw. If winning claims in the relevant category exceed its pool, awards are reduced proportionally. The calculator shows the scheduled Ohio prize before sharing, because it does not know the other winning claims.
Presets cover one base-game selection only. They exclude Booster, Bonus Multiplier, add-on costs and combined claims from multiple selections. For another game, enter a fixed gross payout cap only if its rules use one.
What the one-outcome EV model means
The optional EV calculation treats the chosen match count as the only paying result. Every other outcome returns zero in this model. Its break-even probability and expected value are:
Break-even probability = stake ÷ gross payout
One-outcome EV = P(exact matches) × gross payout − stake
Without a cap, the first formula simplifies to 1 ÷ multiplier. If the effective return is below 1×, even a 100% hit rate cannot recover the full stake in this model. With a zero payout, there is no break-even hit rate.
These figures are not the expected loss of a real multi-prize game. For instance, the one-outcome model for 5 of 6 ignores prizes for 3, 4 or 6 matches. To assess the complete paytable, use the RTP calculator or paytable analyzer. The odds calculator shows the full match distribution.
Check the ticket inputs
Stake per selection and draw
Enter the base wager for one selection in one draw. A total ticket cost may include multiple draws, several selections or a paid bonus feature.
Exact matches
Pick count is how many numbers you selected. Match count is how many of those appeared. A 6-pick ticket with 5 matches uses the 5-of-6 line, not the 5-of-5 prize.
The specific game
Ohio and Connecticut use different prizes for some identical results. Video, crypto and other lottery games need their own multipliers. Changing the stake does not change the draw probability.

Preset sources
The base-game payouts, permitted wagers and prize limits were checked against these official sources on 11 September 2026. Presets use 80 numbers, 20 drawn and 1–10 picks; unspecified match counts pay zero.

Frequently asked questions
How do I calculate a Keno payout from matched numbers?
Choose the correct prize table, enter how many numbers you picked and matched, then enter the base stake for one selection in one draw. The preset loads the matching prize automatically. For an unlisted game, use manual mode and enter its total-return multiplier.
What does 5 out of 6 pay?
It depends on the game. The Ohio base schedule pays $57 per $1 for 5 matches from 6 picks; Connecticut pays $50 per $1. On a $5 base wager, those examples return $285 and $250 respectively, before taxes.
Is the original stake included in the payout?
The calculator uses total-return multipliers. Gross payout is the amount returned; net profit or loss is that amount minus the original stake. A 5× total return on a 10 stake gives a payout of 50 and profit of 40.
Can zero matches pay a Keno prize?
Yes, when that exact result is included in the game’s paytable. For example, the Ohio base schedule pays $5 per $1 for zero matches on a 10-pick selection. Other pick counts and games can pay nothing for zero matches.
Why is a payout lower than stake times multiplier?
A fixed gross prize cap may limit it, or a shared prize pool may reduce the final award. Connecticut base-game calculations apply the $100,000 cap. Ohio top-prize results are marked as scheduled amounts before any shared-prize reduction.
Does the calculator include bonus multipliers?
The lottery presets cover the base game only. They do not include Ohio Booster or Connecticut Bonus Multiplier, their additional costs, or their separate prize rules.
Does the EV result show the return of the whole game?
No. The optional one-outcome EV model counts only the selected hit line and assumes every other outcome pays zero. Use the RTP calculator or paytable analyzer to include all paying results.
Can I use this calculator for video or crypto Keno?
Use manual mode with the game’s own draw format, total-return multiplier and any fixed gross payout cap. Do not apply the Ohio or Connecticut prize schedule to another game merely because it also uses an 80/20 draw.
