How to Use This Calculator

Provide stake, decimal odds for the first leg, and decimal odds for the second leg that only runs if the first wins. Output shows simplified potential profit from the second leg given the first wins.

If-win chains

Matches common “if win” ticket structures at a high level.

Decimals

All odds in decimal form for consistency with the engine.

Not a full ticket parser

Some books cap action or modify stakes—read fine print.

Pair with reverse

Reverse bet uses the same math path with different labeling.

Conditional Stake Model

The calculator mirrors the shared handler: profit from leg one rolls into notional exposure for measuring leg-two profit in a win-win path.

Examples

Example 1 — Stake 50, 2.00, 2.20

Potential from second leg ≈ 60 if the first hits—same numbers as the reverse-bet article defaults.

Example 2 — Short chalk first leg

o1 = 1.40 shrinks profit available to roll.

Example 3 — Longshot second leg

High o2 raises conditional profit but A still must win first.

Frequently Asked Questions

Naming differs by book; math here is the same simplified roll-forward.

Not in this two-leg UI—extend manually or use parlay tools for simultaneous legs.

Educational only—confirm payouts on your slip.

Books may cap conditional action separately from straight limits.
