Gain & Loss Percentage Calculator — Trading Account

Gain % = ((Ending Balance − Starting Balance) ÷ Starting Balance) × 100. If you started with $10,000 and ended with $11,500, your gain = (1,500 ÷ 10,000) × 100 = 15%.

Because after a loss, your base is smaller. A 20% loss on $10,000 leaves $8,000. To get back to $10,000 from $8,000, you need a 25% gain — not 20%. This asymmetry gets more severe with larger losses: a 50% loss needs a 100% gain to recover.

Consistently achieving 3–5% per month is considered excellent for a retail forex trader. Many professional fund managers target 1–2% per month. Be highly skeptical of anyone claiming 20%+ per month consistently — it is almost always unsustainable.

Record your account balance at the same time each week or month and use this calculator to measure your gain or loss percentage for each period. Over time, calculate your average monthly return and compare it to your drawdown periods to evaluate your strategy's consistency.

Recovery % = (Loss % ÷ (100 − Loss %)) × 100. Examples: 10% loss needs 11.1% gain. 20% loss needs 25% gain. 30% loss needs 42.9% gain. 50% loss needs 100% gain. 70% loss needs 233% gain. This is why limiting drawdown is the single most important rule in trading — recovery gets exponentially harder as losses grow.
