Betting ROI Calculator — Yield & Net Profit
Measure realized betting yield from net profit and total stakes.
How it works
Betting ROI (yield here) is net profit divided by all money staked, multiplied by 100. Include every settled stake, even when you reuse winnings.
Use matching dates, currency and costs for both inputs. This measures past results, not expected value, annual returns or growth of your starting bankroll.

How the Betting ROI Calculator — Yield & Net Profit works
Use this betting ROI calculator to measure realized yield over a set of settled bets. Enter total money staked and net profit after costs. Negative profit produces negative ROI, while zero profit means break-even.
Betting ROI formula and example
ROI = net profit ÷ total staked × 100. If you stake 1,000 and receive 1,080 after costs, your net profit is 80 and your ROI is 8%. A loss of 80 over the same turnover gives −8%.
Total staked means betting turnover, including money reused for later bets. It is not your deposit, starting bankroll or total payout. If you have returns instead of profit, subtract the stakes first.
What to include in the inputs
Use the same period and currency for both inputs. Include settled winning and losing bets and subtract exchange commission or other costs consistently. Exclude open bets. For refunded bets, either include the stake and matching refund or exclude both; use the same convention when comparing records.
This calculator uses yield and ROI to mean profit divided by turnover. It does not annualize results or estimate future profitability. Use Bankroll Tracker for individual bet records and Expected Value (EV) Calculator for expected value before a bet.
FAQ
Are betting ROI and yield the same?expand_more
Here both mean net profit divided by total staked. Some reports use starting bankroll as the ROI denominator, so check the definition before comparing figures.
How do I calculate ROI for losing bets?expand_more
Enter a negative net profit. Staking 500 with a net loss of 50 gives −10% ROI. Losing the entire stake gives −100%.
Does a positive ROI prove a betting edge?expand_more
No. It describes the selected past results. Small samples, unusually large wins and omitted costs can make the percentage misleading.
