Enter any starting and ending balance to see your exact gain or loss percentage, dollar amount, and the recovery percentage your remaining balance must achieve. Use this after every trading week to track true performance and feel the asymmetric math that makes capital preservation the first rule of trading.

Why Use the Gain & Loss % Calculator?
Standard percentage calculators tell you the loss percentage but miss the asymmetric recovery math — the reason why preserving capital is more important than chasing gains. A 25% loss needs a 33.3% gain to recover. This calculator shows both the performance and the exact recovery required so the math of drawdown prevention becomes impossible to ignore.
Formula Used
Gain % = ((Ending Balance − Starting Balance) ÷ Starting Balance) × 100Worked Example
Account started at $15,000, now at $11,250. Loss = ($15,000 − $11,250) ÷ $15,000 × 100 = 25%. Recovery needed = ($15,000 − $11,250) ÷ $11,250 × 100 = 33.3%. From $11,250 you must earn $3,750 to break even — that's one-third of your remaining balance, on a base that is now smaller. At 3% monthly returns, recovery takes 9 months.
How to Use the Gain & Loss % Calculator — Step by Step
- 1
Enter your starting balance
Input your account balance at the beginning of the period you want to measure — the start of the week, month, or year.
- 2
Enter your ending balance
Input your current or final account balance at the end of the period.
- 3
Read your gain or loss percentage
The calculator shows your exact percentage gain or loss, the dollar amount won or lost, and your return on investment.
- 4
Check recovery needed (if a loss)
If your account declined, the calculator shows exactly what percentage gain you need to return to your starting balance — this is always higher than the loss percentage due to the math of drawdown recovery.
What Your Gain & Loss % Calculator Results Mean
Gain or Loss %
The percentage change in your account balance between the two entered dates or balance levels. Positive = growth, negative = decline.
Dollar Amount Won or Lost
The actual dollar change in your account. Use this alongside the percentage to understand absolute performance — a 10% gain means different things on a $1,000 account vs a $100,000 account.
Recovery % Required
Only shown for losses — the exact percentage gain needed on your current (reduced) balance to return to the starting balance. Always higher than the loss % due to the mathematics of asymmetric drawdown recovery.
Gain & Loss % Calculator — Frequently Asked Questions
Q.How do I calculate percentage gain on my 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%.
Q.Why does recovery always require a higher percentage than the loss?
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.
Q.What is a good monthly return for a forex trader?
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.
Q.How do I track my trading account performance over time?
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.
Q.What gain percentage do I need to recover from a loss?
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.
