Profit Factor vs Recovery Factor. What's the difference?
Two of the most quoted metrics in a backtest, and they measure different things: one the efficiency of your edge, the other how well returns survive the worst drawdown.

Two of the most quoted metrics in a backtest, and they measure different things: one the efficiency of your edge, the other how well returns survive the worst drawdown.
Profit factor is gross profit divided by gross loss: it measures how efficiently a strategy turns losing trades into winners. Recovery factor is net profit divided by maximum drawdown: it measures how large the return is compared with the worst equity dip along the way. Profit factor tells you whether there is an edge; recovery factor tells you whether that edge is worth the risk taken to earn it. A strategy you can actually trade needs both.
Both come straight out of a backtest report, and both are single numbers, but they answer different questions. One is about the quality of each trade; the other is about surviving the worst stretch. Here is how they compare.
| Aspect | Profit factor | Recovery factor |
|---|---|---|
| Formula | Gross profit / gross loss | Net profit / max drawdown |
| Measures | Efficiency of the edge | Return vs worst drawdown |
| Good value | > 1.5 (strong > 2.0) | > 2-3 (strong > 5) |
| Considers drawdown? | No | Yes |
| Considers trade efficiency? | Yes | No |
| Most sensitive to | A few big winners or losers | The depth of the worst equity dip |
| Answers | Is there an edge? | Is the edge worth the risk? |
Profit factor is the sum of all winning trades divided by the absolute sum of all losing trades: gross profit over gross loss. A profit factor of 1.0 means wins and losses cancel out; 2.0 means the strategy made twice as much on winners as it lost on losers. It is a clean measure of the per-trade edge, but it says nothing about the order of the trades, so a strategy can have a healthy profit factor and still go through a brutal losing streak. As a rule of thumb, around 1.5 is solid and above 2.0 is strong, but a very high value on a handful of trades is usually curve-fitting, not skill.
Recovery factor is net profit divided by maximum drawdown: how many times over the strategy earned back its own worst peak-to-trough loss. A recovery factor of 5 means total profit is five times the deepest dip the equity curve suffered. Because it is anchored to drawdown, it captures robustness and risk in a way profit factor cannot: it tells you whether the returns actually justify the pain endured to get them. Below 1 the strategy has not yet made back more than its worst loss; 2 to 3 is decent and above 5 is strong.
The key difference is what each one ignores. Profit factor ignores the path: it treats a smooth equity curve and a violent one identically as long as the win/loss totals match. Recovery factor ignores per-trade efficiency: it only cares about total return relative to the single worst drawdown. That is why they can disagree. A scalping system might show a profit factor of 1.8 but a recovery factor of 0.8 if one bad day wiped out months of gains. A trend system might show a modest profit factor of 1.3 yet a recovery factor of 6 because its drawdowns stay shallow. Read on their own, each hides half the picture.

Profit factor is gross profit divided by gross loss, so it measures how efficiently a strategy turns losing trades into winning ones. Recovery factor is net profit divided by maximum drawdown, so it measures how large the return is compared with the worst equity dip. Profit factor judges the per-trade edge; recovery factor judges robustness against the deepest loss.
Above 1.0 means the strategy is profitable. In practice a profit factor around 1.5 is solid and above 2.0 is strong, though very high values on few trades are often curve-fit rather than real. Always judge it alongside the number of trades and the drawdown.
Recovery factor has no upper bound, but as a rough guide 2 to 3 is decent and above 5 is strong: it means net profit is several times the worst drawdown. A recovery factor below 1 means the strategy has not yet earned back more than its deepest loss.
Yes. A strategy can win efficiently trade by trade, giving a high profit factor, yet suffer one deep drawdown that drags the recovery factor down. That is exactly why the two are read together: one shows the edge, the other shows whether that edge survives its worst moment.
Neither alone. Profit factor tells you if there is an edge; recovery factor tells you if the return justifies the risk taken to get it. A tradable strategy needs both a profit factor comfortably above 1 and a recovery factor that shows returns dwarf the worst drawdown.
Bring your strategy. We build it and test it properly, so the profit factor and recovery factor mean something.
