Stake in.
Exact payout
out.

Enter your stake and odds in any format — American, decimal, or fractional — and get the total payout, net profit, and ROI instantly. No mental arithmetic. No rounding guesses. The formula is simple: payout = stake × decimal odds.

Payout always includes your stake. Profit is what you net above that. The distinction matters — bookmakers sometimes advertise "win $X" (profit) and sometimes "pay $Y" (total), and confusing the two is one of the most common betting math errors.

Derivation · payout formula

The math behind payout

The core formula is: Payout = Stake × Decimal Odds. Decimal odds include stake return, so the formula already handles it. Profit = Payout − Stake.

At -110 American (1.909 decimal): Payout = $100 × 1.909 = $190.91. Profit = $190.91 − $100 = $90.91. ROI = ($90.91 / $100) × 100 = 90.91%.

Converting American odds first

American odds need to be converted to decimal before using the payout formula. For positive American odds: decimal = american / 100 + 1. For negative: decimal = 100 / |american| + 1.

So at +200: decimal = 200/100 + 1 = 3.00. At $50 stake: $50 × 3.00 = $150.00 payout, $100.00 profit, 200% ROI.

Free bet payout differs

A free (bonus) bet works differently. The stake is not returned on a win — only the profit is paid. At +200 with a $50 free bet: payout = $100 profit only (no stake return). This is a critical distinction for matched betting. Use the bonus bet calculator to correctly size the hedge for a free bet.

FAQ

Common questions

How do I calculate betting payout?
Payout = stake × decimal odds. Total return (payout) includes your stake back. Profit = payout − stake. At -110 (1.909 decimal) with a $100 stake: payout = $100 × 1.909 = $190.90 total. Profit = $190.90 − $100 = $90.90. The stake is always included in the return figure — that's why even-money odds are 2.00 decimal, not 1.00.
What is the difference between payout and profit?
Payout is the total amount you receive if your bet wins — it includes your original stake. Profit is what you actually gain — payout minus stake. A $100 bet at 2.00 decimal (even money, +100 American) pays out $200, but profits only $100. Bookmakers sometimes advertise "win $100" (profit) and sometimes "pays $200" (payout) — always check which one is being quoted.
What does ROI mean in sports betting?
ROI (Return on Investment) is your profit as a percentage of your stake. Formula: ROI = (profit / stake) × 100. At -110 with a $100 stake, profit is $90.91, so ROI = 90.91%. For positive American odds, ROI equals the odds number itself (+150 = 150% ROI). For negative American odds, ROI = 100 / |american| × 100. A long-term positive expected ROI is how professional bettors measure edge.
Can I calculate payout for parlay bets?
For a parlay, multiply the decimal odds of all legs together, then use the result as a single decimal. Example: 3-leg parlay at -110/-110/-110 (1.909 each): combined decimal = 1.909 × 1.909 × 1.909 ≈ 6.96. A $100 parlay pays $696 total ($596 profit). Note that parlays are not independent — if one leg fails, you lose everything. Use the no-vig calculator first to verify each leg's fair odds before building a parlay.
Do bookmakers take a cut from my winnings?
Yes — it's built into the odds. The vig (vigorish or juice) is baked into every line. At -110/-110 on a spread, both sides imply 52.38% probability (summing to 104.76%). The extra 4.76% is the bookmaker's margin. You don't pay a separate fee — but you accept slightly worse-than-fair odds on every bet. Run your intended line through the no-vig calculator to see exactly what the fair payout should be.
What does -110 payout on $100?
-110 American converts to 1.909 decimal. On a $100 bet: payout = $100 × 1.909 = $190.91 total. Profit = $90.91. The -110 standard spread line means you must bet $110 to win $100 — or equivalently, $100 to win $90.91. This is the most common US sports betting line for spread and totals markets.
What does +200 payout on $50?
+200 American converts to 3.00 decimal. On a $50 bet: payout = $50 × 3.00 = $150.00 total. Profit = $100.00. ROI = 200%. At +200, you double your profit relative to stake — a 2-to-1 underdog by the book's assessment. The implied probability is 1/3.00 = 33.33%.
