Free calculators built for bonus hunters. Run the math before you place the bet.
Bonus Bandit tools are designed to sanity-check promotional math after you have read the relevant offer terms. A calculator can estimate expected value, conversion rate, or net bonus value, but it cannot verify account eligibility, state access, KYC approval, sportsbook limits, casino game weighting, cashback tracking, or whether an affiliate offer is still active.
For best results, open the offer or review page first, copy the exact bonus amount and restrictions, then run the numbers. If the tool output depends on a term that is not visible in the source, treat the result as a rough model and return to the operator, issuer, or platform page before acting.
Convert any free bet or risk-free bet into guaranteed cash. Enter your back and lay odds and see your exact profit instantly.
LIVECalculate the expected value of any casino bonus. Plug in the bonus amount, wagering requirement, and game type to see if it's worth taking.
LIVEAutomatically find the closest matching odds across sportsbooks for your qualifying and free bets. Maximize conversion rates with less effort.
COMING SOONScan odds across multiple sportsbooks in real time to find guaranteed arbitrage opportunities. Lock in profit regardless of the outcome.
COMING SOONUse the free bet calculator when a sportsbook promotion has clear odds and stake rules. Use the EV calculator when a casino or bonus-churning offer has a visible wagering requirement and game weighting. For cross-vertical planning, use the bonus stacking calculator with the vertical hubs, methodology, and affiliate disclosure.
The right workflow is evidence first, math second, action last. Screenshots, source links, and conservative assumptions keep the calculators useful and safer for readers who are comparing affiliate offers.
If a tool result looks unusually strong, slow down and check the source again.
Document the inputs.
Then rerun the math.
Unreleased tools stay off the public grid until they have working inputs, visible assumptions, and the same disclosure links as the live calculators.
