Drawdown Recovery Calculator

This drawdown recovery calculator shows the gain needed to recover from a portfolio drawdown and how many years it takes at your assumed return, in any market.

What it does

The Drawdown Recovery Calculator shows the gain you need to climb back to your previous peak after a portfolio fall, and how long that recovery takes at an assumed annual return. A drawdown of 20% needs a 25% gain to break even, because the recovery is measured from the smaller balance left after the loss.

Data sources & parameters

This calculator uses standard financial formulas and runs entirely in your browser. It needs no external rate data — your result is computed only from the values you enter above.

We always strive to use the latest data for every variable so our results and reports are as accurate as possible. Even so, errors are possible — you should not rely on this tool or its report alone, and we accept no liability for any decision made based on it.

The formula

gain_to_recover = d / (100 - d) x 100; years = ln(1 / (1 - d/100)) / ln(1 + r/100), where d is the drawdown % and r the annual return %

How it works

It divides the drawdown by what remains after the loss to find the break-even gain, then uses a compound-growth formula to translate that gain into years at the return you assume.

Worked example

A portfolio falls 20% from its peak. To break even it must gain …, not just the 20% it lost, because the gain is measured from the lower balance. At an assumed 8% annual return, that takes about … years.

What the drawdown recovery calculator does

The drawdown recovery calculator tells you how much you need to gain after a fall to get back to where you were, and how long that might take. A drawdown is the drop from a portfolio's peak to its low point, expressed as a percentage. Earning back the same percentage you lost is not enough, because the gain is measured from a smaller starting balance.

Enter the drawdown as a percentage and an assumed annual return, and the calculator shows the gain required to break even, the number of years that gain takes at your chosen return, and the drawdown you entered beside the result.

The recovery asymmetry

Losses and the gains that reverse them are not symmetric. A portfolio that falls 20% needs a 25% gain to recover, because the rise starts from the reduced balance the loss left behind.

Start with 100 units of value and lose 20%, and you are left with 80. To return to 100, you must gain 20 on a base of 80, and 20 divided by 80 is 25%. The percentage you must earn back is always larger than the percentage you lost, and the gap grows quickly as losses deepen.

A 10% loss needs about an 11.1% gain.
A 20% loss needs a 25% gain.
A 33% loss needs roughly a 50% gain.
A 50% loss needs a 100% gain.
A 75% loss needs a 300% gain.

Lose three quarters of your capital and the remaining quarter must quadruple to break even. This arithmetic is behind the old investing maxim that avoiding large losses matters more than capturing large gains.

How the calculation works

The break-even gain is the drawdown divided by the capital that remains after the loss, as a percentage. In symbols, the gain to recover equals the drawdown divided by one hundred minus the drawdown, multiplied by one hundred.

To convert that gain into time, the calculator assumes a steady compound annual return. The number of years to recover is the natural logarithm of one divided by the surviving fraction, divided by the natural logarithm of one plus the return: the number of years of compounding at your assumed rate needed to produce the required gain.

If you enter a return of zero, the tool reports zero years, because a portfolio that does not grow can never recover through returns alone. The break-even gain still appears, so you can see the size of the hole.

Using the calculator

Enter the drawdown, the peak-to-trough loss, as a percentage.
Enter the annual return you expect the portfolio to earn during the recovery.

The currency symbol is only for display. The same drawdown produces the same recovery gain and the same recovery time in every market and every currency.

Reading the results

The gain to recover shows how steep the climb back is. A modest drawdown needs a gain only slightly larger than the loss, but a severe one needs a gain that dwarfs it.

The years to recover puts the setback in time. At an 8% assumed return, a 20% drawdown recovers in a little under three years. Halve the return and the time roughly doubles; deepen the drawdown and it climbs sharply. A loss then reads as a stretch of lost progress toward your goals as well as a percentage.

Why this matters for risk

An investment that can fall far in a bad year carries a long recovery that can consume years of potential growth. Two portfolios with the same average return can end up in very different places if one suffers deep drawdowns along the way, because the recovery arithmetic works against it every time.

For this reason many long-term investors value consistency and downside protection. Smoothing out the deep falls, even at the cost of some upside, can leave you better off because you spend fewer years recovering.

Limitations

The recovery time assumes a steady return, which real markets never deliver; recoveries come in fits and starts and can be far slower or faster than a smooth average suggests. The tool also ignores contributions, and money added during a downturn buys in at lower prices and can speed the return to a previous peak. It says nothing about whether a recovery will happen at all, only what it would take if your assumed return held.

Frequently asked questions

How does the drawdown recovery calculator work?

You enter the size of the drawdown as a percentage and an assumed annual return. The calculator divides the loss by what is left after it to find the gain needed to break even, then uses a compound-growth formula to estimate how many years that gain takes at your chosen return.

Why does a 20% loss need a 25% gain to recover?

Because the recovery is measured from the smaller balance left after the fall. A 20% loss on $100 leaves $80, and getting from $80 back to $100 is a $20 gain on an $80 base, which is 25%. The deeper the loss, the wider this gap becomes.

What gain do I need after a 50% drawdown?

A 50% loss requires a 100% gain to break even. Half your money is gone, so the remaining half must double to return to the starting point. This is why deep drawdowns do so much damage and why avoiding them matters as much as chasing returns.

Is the recovery time a prediction?

No. It is a simple projection based on a steady assumed return. Real markets recover along an uneven, unpredictable path, sometimes faster and sometimes far slower. Treat the years figure as a rough sense of the scale of the setback, not a forecast.

Does the calculator use real market data?

No. It holds no market data and makes no forecast. Every figure comes from the drawdown and return you enter, and the whole calculation runs in your browser, so nothing you type is uploaded or stored.

Can I use this for any country or currency?

Yes. Drawdown recovery is pure percentage maths, so it works identically in every market and currency. There is no tax, no region, and no currency assumption built into the result.
