How to Use This Calculator
Enter net profit over a period and total amount risked (sum of stakes you put in play). ROI expresses return per dollar of risk, not per dollar of bankroll unless those coincide.
Net profit
Wins minus losses after fees, not gross winnings.
Total risked
Typically the sum of all stakes for settled bets in the sample. Define consistently with how you track the account.
Compare samples
ROI swings with variance—use enough volume for signal.
Pair with CLV
Positive ROI with positive closing line value is a strong story; negative ROI with positive CLV can still happen short term.
What ROI Means
ROI answers: “For each dollar I risked, how many cents did I earn?” A 5% ROI means $0.05 profit per $1 of risk on average over the window you measured.
Formula
ROI = net profit ÷ total amount risked
Examples
Example 1 — Defaults
Profit $500, risked $10,000 → ROI = 5.00%.
Example 2 — Break-even
Profit $0 on $5,000 risk → 0% ROI.
Example 3 — Losing month
Profit −$300 on $6,000 risk → −5% ROI—compare to your CLV log to see if process or variance dominated.
Frequently Asked Questions
Often yes in flat-staking summaries. If bet sizes change, be explicit about what “risked” includes.
Decide a rule—either count bonus profit in net profit or exclude it for a “pure betting” ROI.
Low single digits can be excellent at scale; double-digit ROI over small samples often reflects variance.
Bankroll return mixes staking strategy with edge. ROI on risk isolates betting performance.
No—only profit and risk totals. Odds enter indirectly through results.
