13. How is Profit or Loss Calculated in Futures?
What Are Futures Contracts?

A Futures Contract is an agreement to buy or sell an asset at a predetermined price on a future date. Traders use these contracts to:

Basic Formula for Calculating Profit or Loss

Profit or Loss = (Exit Price – Entry Price) × Lot Size × Number of Lots

This formula applies whether you're buying first (going long) or selling first (going short) — the only difference is in the trade direction.

Direction Matters: Long vs Short
Position TypeAction SequenceProfit When…Loss When…
Long (Buy 1st)Buy → SellSell Price > Buy PriceSell Price < Buy Price
Short (Sell 1st)Sell → Buy BackBuy Back Price < Sell PriceBuy Back Price > Sell Price
Example 1: Long Position on Nifty Futures

Profit = (22,250 - 22,000) × 50 = ₹12,500

Example 2: Short Position on Bank Nifty Futures

Profit = (48,500 - 48,200) × 15 = ₹4,500

In short selling, you gain when the market falls.

Example 3: Loss Scenario in Long Position

Loss = (59,500 - 60,000) × 100 = -₹5,000

Advanced Concept: MTM (Mark-to-Market)

In Futures, profit/loss is not settled only at expiry. Instead, positions are marked to market daily:
