Betting calculators
Free, fast betting calculators that work on any phone, even offline once the page has loaded: payouts, accumulators, odds conversion, implied probability and an optional Zimbabwe tax estimate.
Implied probability calculator
Turn decimal odds into the chance the bookmaker is implying, and measure the bookmaker's margin on a whole market such as the three 1X2 prices.
Odds converter
Convert odds between decimal (2.50), fractional (3/2) and American (+150) formats, and see the implied probability.
Betting payout calculator
Enter your stake and decimal odds to see the gross payout and the gross profit before any deductions.
Zimbabwe betting tax calculator
An optional tool to estimate how a tax deduction at a rate you choose would change a winning bet's payout. It is a hypothetical estimate, not a statement of what any bookmaker deducts.
A note on payouts and profit
All our calculators clearly separate the gross payout (what a winning bet returns, including your stake) from the gross profit (payout minus stake). Neither figure includes tax or fees; if you want to see the effect of a deduction, use the separate tax estimate calculator.
Calculators show what a bet would pay. They cannot tell you whether it will win. Read how bookmakers make money to understand why.
