Max Drawdown Calculator (India)

Paste your equity curve and see the worst peak-to-trough loss, the recovery gain required to break even, and the longest underwater stretch. Works for any portfolio — stocks, F&O, mutual funds, SIPs.

Track drawdown automatically as you trade

ArthaLearn computes rolling max DD across your imported trades and alerts you when DD crosses your discipline limits. Works with Zerodha, Upstox, Groww, Angel One, Dhan & 5paisa.

The asymmetry of drawdown recovery

Drawdown and recovery are not symmetric. A loss of 50% requires a gain of 100% to recover — not 50%. This is the single most important number Indian retail traders learn too late.

DrawdownRecovery neededRealistic? (Indian retail)
10%+11.1%Routine
20%+25.0%Achievable in 12-18 mo
30%+42.9%Hard — review strategy
50%+100.0%Most never recover
70%+233.3%Effectively ruined
90%+900.0%Account is dead

Drawdown discipline rules used by survivors

  • Hard stop at 25-30% DD: stop trading, do a written post-mortem, re-paper-trade for 4 weeks before re-entering with reduced size.
  • Position-size haircut at 15% DD: reduce risk-per-trade by half until equity recovers to within 5% of peak. Prevents drawdown spirals.
  • Track time-underwater, not just depth: a 10% DD that lasts 2 years destroys more capital (opportunity cost) than a 25% DD that recovers in 3 months.
  • Calendar-time DD ceiling: if monthly DD crosses 8%, take 2 weeks break. If quarterly DD crosses 15%, full strategy review.

Why this matters for SIP investors too

India's most expensive investing mistake is stopping SIPs during deep market drawdowns. Studies of Indian MF investor behaviour show that the median SIP investor buys at the top, panics at the bottom, and exits with a return well below the fund's. Pre-knowing your tolerance — by computing what 30% / 40% / 50% drawdown looks like in actual rupees on your portfolio — is the cheapest behavioural insurance available.
