Bet Calculator

Calculate potential returns from singles, accumulators and system bets

Total Return
R640.00
Total Profit
R440.00
Return on Investment (ROI): 220.00%

How it works

Enter your stake and odds to see potential returns. Supports single bets and accumulators. Results show profit, total return and return on investment.

Quick Example Scenario:

You want to bet R200 on Kaizer Chiefs to beat Orlando Pirates at decimal odds of 3.20.

  • Step 1: Enter stake: R200
  • Step 2: Enter odds: 3.20
  • Total return = R200 x 3.20 = R640
  • Profit = R640 - R200 = R440

Accumulator Calculator

Work out combined odds and returns for multi-leg bets

Combined Odds
11.88
Total Return
R594.00

How it works

Add multiple selections with their individual odds. The calculator multiplies them together to give you combined odds and total potential returns.

Quick Example Scenario:

Weekend PSL four-fold accumulator with R50 stake.

  • Leg 1: Chiefs @ 1.80 | Leg 2: Pirates @ 2.10 | Leg 3: Sundowns @ 1.65 | Leg 4: Stellies @ 2.40
  • Combined odds = 1.80 x 2.10 x 1.65 x 2.40 = 11.88
  • Total return = R50 x 11.88 = R594.00

Each Way Calculator

Calculate returns for each-way bets on horse racing

Total staked: R100
If horse wins (Win + Place payout)
Total Return
R725.00
Profit
R625.00
If horse places (Place payout only)
Total Return
R175.00
Net Profit/Loss
R75.00

How it works

Enter odds, each-way terms (e.g. 1/4 odds) and stake to see returns for win and place separately. Remember that an each-way bet doubles your unit stake (one bet to win, one to place).
