Recovery Factor Calculator

Compare net profit against the largest drawdown to see how much was earned per unit of pain endured.

The recovery factor asks how many times a record earned back its own worst loss. This recovery factor calculator divides the net profit over the whole period by the deepest peak-to-trough decline suffered along the way, both figures in cash: net profit to drawdown, with nothing else in the calculation. A factor of 3 says the account finished three of those declines ahead of where its worst moment left it; a factor below 1 says it has not yet made back more than it once gave up in a single stretch.

Formula: recovery factor = net profit / maximum drawdown

Your figures

Currency

Net profit

Over the whole record, after costs. A record that finished down is entered as a negative figure — it is reported rather than refused.

Maximum drawdown suffered

The deepest peak-to-trough loss in cash, entered either way round — the sign is ignored.

Starting balance

Optional. Expresses both amounts as a percentage of the account they were earned on. It does not change the factor itself.

What this means

Net profit of +US$24,000.00 divided by a deepest decline of US$8,000.00 gives a recovery factor of 3.00. The record earned back 3.00 times its own worst drawdown; below 1 would mean it had yet to make back more than it once gave up in a single decline. Against the starting balance that is +24.00% of profit and 8.00% of drawdown, and dividing one by the other gives the same factor — scaling both amounts by the same figure leaves their ratio untouched. It is the Calmar ratio's arithmetic in cash and without annualising, so it says nothing at all about time: the same factor reached over one year and over five describes two very different records.

Neither figure is annualised, so the factor cannot be compared across records of different lengths without saying how long each one ran.
The drawdown is a single event. One unusually bad stretch sets it, and a record that has not had that stretch yet divides by a smaller number.
The starting balance changes nothing about the factor — dividing both amounts by the same figure leaves their ratio where it was. It is there because the same two amounts read differently on a large account than on a small one.
Net profit is whatever the record actually produced after costs, as entered. Fees, financing and tax are only in it if they were in the figure typed.
This describes a record that has already happened. It is a summary of the figures entered, not a statement about what follows them, and no particular level of it carries a meaning beyond the arithmetic that produced it.

About the Recovery Factor calculation

The calculator takes the net profit over the record, the deepest drawdown in cash with its sign ignored, and an optional starting balance. It reports the factor, and where a balance is supplied, both amounts as percentages of it. Those percentages are context rather than inputs: dividing the profit and the drawdown by the same number leaves their ratio exactly where it was.

It is the Calmar ratio's arithmetic with two things removed — the percentages and the annualising — which makes it simultaneously more honest and less comparable. More honest on a record too short to annualise, because nothing is extrapolated from a handful of months into a claim about a year. Less comparable across records, because a factor of 3 earned over one year and a factor of 3 earned over five are the same number describing very different things.

Recovery Factor formula

recovery factor = net profit ÷ |max drawdown|

with a starting balance, for context only:
  net profit %   = net profit ÷ starting balance × 100
  max drawdown % = |max drawdown| ÷ starting balance × 100

net profit: What the record produced over its whole length, after costs. A losing record is entered as a negative figure.
|max drawdown|: The deepest peak-to-trough loss in cash. The sign is ignored, since the same decline is written both ways in practice.
starting balance: Optional. Expresses both amounts against the account they were earned on without altering the factor itself.

Both figures are cash amounts drawn from the same account, so the currency cancels and the result is a pure number. Working in cash also avoids a subtlety that catches people out in the percentage version of this ratio: a percentage profit is measured against the opening balance, while a percentage drawdown is measured against whatever peak that particular decline began from, and those are two different denominators quietly compared as though they were one. In cash there is only ever a single account behind both.

A negative net profit is reported rather than refused. The factor then carries the sign, and it carries real information with it — a record sitting half a drawdown below water is in a very different position from one sitting three drawdowns below it, and declining to divide would hide precisely the case a reader most needs to look at. The unsigned multiple is shown alongside so that the sentence reads correctly in either direction.

The value of 1 is one of the few thresholds in performance statistics with a plain meaning rather than a conventional one. It does not depend on a distribution, a target, a period count or a benchmark: below 1 the account has not made back what it once gave up in a single decline, at 1 it has exactly matched it, and above 1 it is ahead by that many multiples. Two amounts from the same statement are all it takes to read.

Nothing in the formula mentions time, which is the property to hold on to when reading the result. The same factor of 3 describes a record that took one year and a record that took five, and the second is a fifth as productive per year while scoring identically. Whenever the figure is quoted the length of the record has to be quoted with it — and adding that dimension by annualising the numerator is exactly what turns this into the Calmar ratio.

Recovery Factor: a worked example

A record that finished $24,000 up, having at its worst point been $8,000 below a previous peak, on an account that started at $100,000.

Net profit+$24,000
Maximum drawdown, sign ignored$8,000
Recovery factor24,000 ÷ 8,000 = 3.00
Net profit against the starting balance24,000 ÷ 100,000 = 24.00%
Drawdown against the starting balance8,000 ÷ 100,000 = 8.00%
The same division in percentages24.00 ÷ 8.00 = 3.00

A recovery factor of 3.00: the record earned back its own deepest decline three times over. The last three steps make the point about the starting balance — scaling both amounts by the same $100,000 leaves the ratio exactly where it was, so the balance is there to help you read the two amounts rather than to change the factor. What the factor still does not tell you is how long any of it took.

How to use the Recovery Factor calculator

Enter the net profit over the whole record, after costs. Whatever is in the figure typed is in the answer, since nothing is deducted here.
Enter the deepest peak-to-trough loss in cash rather than the largest losing trade. They are different numbers, and the second is usually far smaller.
Type the drawdown either way round. Only its size divides, so −8,000 and 8,000 produce the same factor.
Add the starting balance if you want both amounts expressed against the account. It is context only and leaves the factor untouched.
Note how long the record ran, separately. The factor has no time dimension of its own and cannot be compared with another one without it.

Limitations of the Recovery Factor calculator

Every calculation makes assumptions. These are the ones that matter here.

The factor is silent about time. A record of one year and a record of five produce the same number from the same two amounts, so comparing them without stating both lengths says nothing.
The drawdown is a single event, so one unusually bad stretch fixes the denominator, and a record that has not had its bad stretch yet is dividing by a smaller number than it eventually will.
Net profit is one end-to-end figure. A record that made everything in a single month and drifted for the rest scores identically to one that ground the same amount out steadily.
Costs, financing and tax appear only if they were already inside the net profit entered. A gross figure gives a flattering factor that no account ever actually experienced.
Where a starting balance is supplied, the drawdown percentage is measured against that opening balance rather than against the peak the decline actually began from. The two differ whenever the account was ahead when the decline started.
Deposits and withdrawals are not modelled. Money added mid-record inflates the profit with no trading behind it, and money added during a decline shortens the drawdown it is divided by.

Frequently asked questions about Recovery Factor

What does a recovery factor below 1 mean?

That the record has not yet made back more than it gave up in its single worst decline. It is a description of two amounts rather than a verdict on the strategy: an account six months into a long horizon and one that has stalled after five years can report the same figure, and only the record length separates them.

How is this different from the Calmar ratio?

Both are profit-to-drawdown ratios: the same division, in different units, with one extra step. The Calmar ratio annualises the numerator and works in percentages, which lets it be compared across records of different lengths. The recovery factor stays in cash and does not annualise, which makes it usable on a record too short for an annual figure to mean anything — at the cost of saying nothing at all about time.

Should the largest losing trade be used as the drawdown?

No. The maximum drawdown is the deepest fall from a peak in the equity curve, which normally spans a run of trades rather than one. Using the worst single trade would understate the denominator, often heavily, and inflate the factor by the same proportion without any of that showing in the result.

Does the starting balance change the factor?

No, and the worked example shows it rather than asserting it: dividing a $24,000 profit and an $8,000 drawdown both by $100,000 gives 24% and 8%, and 24 ÷ 8 is still 3. The balance is offered because those two amounts read very differently on a $30,000 account than on a $1,000,000 one.

Why is a negative factor reported instead of an error?

Because a losing record is still a record. The sign says the account finished down and the magnitude says by how much, measured in units of its own worst decline. Suppressing it would remove exactly the case worth examining, so both the signed factor and the unsigned multiple are shown together.

Can a strategy recovery factor be taken from a backtest?

Yes. The recovery factor trading platforms print at the foot of a strategy report is this same division, so a backtested figure and a live one are at least on the same scale. Nothing in the calculation can tell the two apart, though, which is the thing to be careful about: a curve fitted to its own sample tends to show a shallow drawdown, because the periods that would have caused a deeper one are the periods the parameters were chosen to sidestep.
