Formula
Balance after loss = starting balance × (1 − loss percent ÷ 100). Gain needed = starting balance ÷ balance after loss − 1. Recovery periods = ln(starting balance ÷ balance after loss) ÷ ln(1 + recovery rate ÷ 100).

100% gain needed10,000.00 before loss -> 5,000.00 after a 50% drawdown. Break-even gain is 100%. At 10% per month, 7.27 months exact, first whole break-even period 8.
Inputs
- Starting balance before loss
- 10,000 currency
- Loss / drawdown
- 50 %
- Recovery growth per period
- 10 %
- Period type
- 3
Method
Balance after loss = starting balance × (1 − loss percent ÷ 100). Gain needed = starting balance ÷ balance after loss − 1. Recovery periods = ln(starting balance ÷ balance after loss) ÷ ln(1 + recovery rate ÷ 100).
- Start at 10,000 and lose 50%, leaving 5,000. To return from 5,000 to 10,000, the needed gain is 10,000 ÷ 5,000 − 1 = 100%. At 10% recovery per period, ln(2) ÷ ln(1.10) = 7.27, so the first whole period at or above break-even is 8 periods.
Assumptions
- This is risk education arithmetic, not trading advice, investment advice or a recovery forecast.
- The recovery rate is treated as a constant positive rate per period; real recoveries are uneven and can include further losses.
- Loss percentage is capped below 100% because a total loss cannot recover by percentage growth from zero.
- Fees, tax, inflation, withdrawals, additional deposits and behavioural risk are not included.

Worked example
Start at 10,000 and lose 50%, leaving 5,000. To return from 5,000 to 10,000, the needed gain is 10,000 ÷ 5,000 − 1 = 100%. At 10% recovery per period, ln(2) ÷ ln(1.10) = 7.27, so the first whole period at or above break-even is 8 periods.
Professional note
Master’s Tip: show both the loss and the required gain. A 50% loss needing a 100% gain is one of the clearest ways to explain why drawdown control matters.

Methodology & Accuracy
How this calculator is checked
CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.
Formula used
Balance after loss = starting balance × (1 − loss percent ÷ 100). Gain needed = starting balance ÷ balance after loss − 1. Recovery periods = ln(starting balance ÷ balance after loss) ÷ ln(1 + recovery rate ÷ 100).
Standard or basis
Standard or basis: transparent drawdown and compound-recovery arithmetic. This is educational only and does not recommend any asset, strategy, leverage level or recovery assumption.
Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.Master's Tip

Questions
Why does a 50% loss need a 100% gain?
After a 50% loss, 100 becomes 50. Getting from 50 back to 100 requires gaining 50 on a base of 50, which is a 100% gain.
What gain is needed after a 20% loss?
A 20% loss leaves 80% of the starting value. The gain needed is 1 ÷ 0.80 − 1 = 25%.
Can a 100% loss recover?
Not through percentage growth from the remaining balance, because the remaining balance is zero. That is why this calculator caps loss below 100%.
Are recovery periods guaranteed?
No. The period count assumes the same recovery rate every period. Real results can be volatile, lower, higher or negative.
Does this recommend taking more risk to recover?
No. It is an educational calculator only. It does not recommend trades, leverage, products or strategies.
Calculation note
Drawdown recovery arithmetic explains an asymmetry that surprises many beginners: losing a percentage and gaining the same percentage do not cancel out. The recovery gain is measured from a smaller base.
Losses change the base
A 10% loss followed by a 10% gain does not return to the starting point. The gain is calculated from the reduced balance, so the account remains below its original value.
The break-even gain curve is nonlinear
Small losses need slightly larger gains, but large losses need dramatically larger gains. A 20% loss needs 25%, a 50% loss needs 100%, and a 90% loss needs 900%.
Why educators use drawdown tables
Drawdown tables help students, savers and traders see risk before thinking about returns. They are simple arithmetic, but they make the cost of large losses visible.
Recovery time is a model, not a promise
The periods-to-recover estimate assumes a constant rate every period. Real markets, businesses and projects do not move that smoothly, so the period count should be treated as a scenario label only.
