How this service works
Gain needed to recover a percentage loss, or the maximum drawdown and recovery gain from a list of period returns.
Output
Returns the required gain percentage to recover from a loss, maximum drawdown from a period-returns series, the corresponding recovery gain needed, estimated years to recover at 7% and 10% annual returns, the input loss percentage, a plain-language summary, and optional disclaimer text.
Example use cases
Single loss recovery calculation
“My investment dropped 40% — what percentage gain do I need to fully recover and get back to where I started?”
Drawdown analysis from monthly returns
“Here are my monthly returns for the past year: 3, -8, 5, -15, 2, 7, -4, 1, 6, -2, 4, 3 — can you find the maximum drawdown and tell me how much gain is needed to recover from it?”
Bear market recovery planning
“The S&P 500 dropped 50% in 2008-2009 — how big a rally was needed to recover that loss, and how many years would it take at 10% annual growth?”
Technical details
Endpoint
GEThttps://invest-math.x402tookit.com/drawdown-recovery?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quantify the asymmetric math of investment losses — specifically how much more you must gain to recover from a drawdown. It handles both a simple single-loss scenario (via lossPct) and full time-series drawdown analysis (via returnsPct). Prefer this over general statistics endpoints when the core question is loss recovery or drawdown impact.
Side effects
- Missing both lossPct and returnsPct parameters returns an error
- lossPct out of range (0-99.9) results in validation failure
- Malformed returnsPct string (non-numeric, wrong delimiter) causes parse error
- Empty returnsPct list returns no drawdown result
- Network timeout or service unavailability returns HTTP 402/503
