What is Calmar Ratio?
Calmar ratio compares how much you grew on an annualised basis to the deepest drawdown you endured. Higher values mean more return per unit of peak pain.
Formula
Calmar ≈ Annualised return ÷ Max drawdown (absolute %)
Indian market context (NSE)
Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how Calmar Ratio shows up on Indian index, equity, and futures books — update to live quotes in your journal.
Nifty 50 perspective
Apply Calmar Ratio to your Nifty 50 sleeve (spot near 24,300): track the metric on closed index F&O or ETF trades over at least 30 sessions before changing rules. NSE costs and slippage on fast opens often widen the gap between spreadsheet calmar ratio and bank P&L.
Reliance Industries perspective
On Reliance (₹1,300) delivery or intraday trades, calculate calmar ratio with contract-note costs included. Single-name results can look strong on calmar ratio while your Nifty-correlated book tells the opposite — tag “RELIANCE” separately in TradeLyser.
Bank Nifty futures perspective
Bank Nifty futures near 55,000 (lot 30) amplify calmar ratio swings versus cash — one volatile session can move the metric more than a week of Nifty trades. Log margin mode (MIS/NRML) with each entry for honest review.
A trader up +24% annualised with −12% max drawdown shows Calmar ≈ 2. Another up +40% with −35% drawdown shows Calmar ≈ 1.14 — higher headline return but worse pain per unit.
How to validate
- Minimum sample: 30 closed trades on one strategy tag before trusting Calmar Ratio.
- Check for one outlier week inflating Calmar Ratio — export largest winners and losers.
- Recompute Calmar Ratio after including brokerage, STT, and slippage on F&O tags.
- Compare Calmar Ratio on the same date range as profit factor and max drawdown.
How to track in TradeLyser
- Open Strategy Board or analytics → filter by strategy tag and review period.
- Locate the widget or column reporting Calmar Ratio (or export trades to compute manually).
- Store snapshot values in weekly review: Calmar Ratio, profit factor, drawdown, trade count.
- If Calmar Ratio is custom, add a spreadsheet column fed from TradeLyser CSV export.
Best practices
- Publish Calmar Ratio per strategy, not only at account level.
- Use the same calculation window (weekly vs monthly) year-round.
- Pair Calmar Ratio with sample size in every review slide or note.
- Reconcile Calmar Ratio with broker statements before tax filing.
Common pitfalls
- Changing rules after fewer than 20 trades because Calmar Ratio moved slightly.
- Mixing intraday and positional tags when computing Calmar Ratio.
- Ignoring costs so Calmar Ratio looks better than banked P&L.
- Letting one outlier trade dominate the Calmar Ratio reading.
How to use this in TradeLyser
Pull annualised return and max drawdown from the same tagged window in analytics. Do not mix tags when reporting Calmar to mentors.

Maximum drawdown records the worst fall from a prior equity high to the subsequent low. It describes pain and capital required to stay in the game — not just the final P&L.
Recovery factor shows how many rupees of net profit you earned per rupee of max drawdown in the window. Higher is better if the sample is honest.
Sharpe ratio measures how much return you earned for each unit of overall volatility. Higher values generally mean smoother growth relative to swings — on a long enough sample.
FAQ
What is a good Calmar ratio?
A Calmar ratio above 1.0 is acceptable, above 2.0 is good, and above 3.0 is excellent. It means your annual returns are 1×, 2×, or 3× your maximum drawdown. Most hedge funds target Calmar ratios between 1.5 and 3.0.
How do you calculate Calmar ratio?
Calmar ratio equals CAGR divided by maximum drawdown (absolute value). If your 3-year CAGR is 25% and maximum drawdown was 15%, your Calmar ratio is 25/15 = 1.67. Use the same time period for both metrics.
What is the difference between Calmar and Sharpe ratio?
Sharpe ratio uses volatility (standard deviation) as the risk measure, while Calmar uses maximum drawdown. Calmar is more intuitive for traders—it shows how many years of returns your worst drawdown could wipe out.
Why is Calmar ratio important?
Calmar ratio directly relates returns to your worst-case scenario. A Calmar of 0.5 means your worst drawdown equals two years of returns—very risky. A Calmar of 3.0 means even your worst drawdown only costs 4 months of average returns.
What time period should I use for Calmar ratio?
Traditionally, Calmar ratio uses a 3-year lookback period. Shorter periods may not capture true maximum drawdown. For active traders, 2-3 years of data provides a reasonable balance between relevance and statistical significance.
