Crypto Risk Reward Calculator: R:R Ratios, Examples, and When They Mislead

What Risk Reward Ratio Means

Risk reward ratio — often written R:R — compares potential loss to potential gain on one trade.

A 1:3 ratio means you risk one unit to seek three units of profit.

• Risk = distance from entry to stop-loss
• Reward = distance from entry to take-profit
• R:R = reward divided by risk
• Higher R:R is not automatically better — hit rate matters

Calculator Inputs: Entry, Stop, Target

Enter three prices and the tool outputs ratio in price or percent terms.

Long and short use the same math with reversed direction.

• Entry = planned fill price
• Stop = price where you exit for a controlled loss
• Target = price where you take profit
• Some tools accept percent risk and percent reward instead of prices

Example: Long With 1:2 R:R

Entry at 100, stop at 95, target at 110.

Risk is 5 per unit. Reward is 10 per unit. R:R is 1:2.

• Risk per coin = entry minus stop = 5
• Reward per coin = target minus entry = 10
• Ratio = 10 divided by 5 = 2 reward units per 1 risk unit
• Break-even win rate near 33% before fees on this shape

Example: Short With 1:3 R:R

Entry at 200, stop at 206, target at 182.

Risk is 6 per unit. Reward is 18 per unit. R:R is 1:3.

• Short risk = stop minus entry
• Short reward = entry minus target
• Ratio = 18 divided by 6 = 3
• Break-even win rate near 25% before fees

Break-Even Win Rate From R:R

Every ratio implies a minimum win rate to break even before costs.

Formula: break-even win rate = 1 divided by (1 + R:R).

• 1:1 needs above 50% wins
• 1:2 needs above roughly 33% wins
• 1:3 needs above roughly 25% wins
• Real win rate must exceed break-even plus fee drag

Fees Adjust the Real Ratio

Taker entry and taker exit shrink reward and slightly widen effective risk.

Net R:R after fees is what survival math should use.

• Subtract round-trip fee percent from reward side
• Add fee percent to risk side on tight stops
• Scalps with 1:1 gross R:R often become negative net
• Use maker entry when possible to preserve ratio

R:R vs Position Size

Ratio does not set size — it sets shape. Size comes from account risk percent.

Same R:R with double size doubles dollar gain and dollar loss.

• Fix stop first based on structure, not desired R:R
• Move target to achieve ratio — do not shrink stop below invalidation
• Position size calculator uses stop distance, not R:R directly
• Good ratio with oversized position still blows the account

When R:R Misleads

Fantasy targets far away inflate ratio without realistic hit rate.

Always pair ratio with historical or tested win rate for your setup.

• 1:10 looks great on paper — almost never hits in chop
• Moving stop after entry changes realized R:R, not planned
• Partial take-profits create blended ratio across legs
• Journal planned vs actual R:R to find honest expectancy

Quick Summary

A crypto risk reward calculator divides target distance by stop distance to produce R:R.

Compare the implied break-even win rate to your realistic hit rate before entry.

Net ratio after fees is the number that matters for expectancy.

• Inputs: entry, stop, target
• Output: R:R and break-even win rate
• Adjust for round-trip fees on both legs
