When to use this calculator

Use when planning a back-first trade with a defined risk-reward ratio. Enter your entry odds, stop-loss exit odds, and desired R:R (e.g. 2:1). The calculator shows your maximum risk, required profit target, and the lay odds you need to hit that target.

Plan your entire trade — entry, stop, and profit target — before the market opens.

Frequently asked questions

What is a risk-reward ratio in trading?

A 2:1 R:R means you target £2 profit for every £1 risked. Higher R:R means fewer wins needed to be profitable, but targets are harder to hit.

Why must stop-loss odds be higher than entry odds?

For a back-first trade, adverse movement means odds lengthen (get worse for you). The stop-loss lay price must be above your entry back price.

Does this include commission?

Enter your commission rate to see net target profit. Gross risk and lay odds are shown before fees.
