Position Size (Units)

Amount at risk ÷ loss per unit

A plan, not a promise. A stop-loss can fill at a worse price in a fast market, so the real loss can be larger. Figures are before tax, and in India a loss on one crypto trade cannot be set off against a profit on another. To see the price that covers fees and tax, use the Crypto Break-Even Calculator.

How it is calculated

The size of the trade is set by how much you are willing to lose, not by how much you want to make.

  • Amount at risk = account size × risk per trade
  • Loss per unit = the gap between your entry and your stop-loss, plus the fee on the way in and on the way out
  • Position size = amount at risk ÷ loss per unit
  • Position value = position size × entry price
  • Potential profit = position size × (the gap between your entry and your target, less the fees)
  • Risk to reward = potential profit ÷ amount at risk

Frequently asked questions

Short answers on sizing a trade and on what this calculator assumes.

It is how much of a coin you buy or sell on one trade. Sizing a position means choosing that amount so that, if the price reaches your stop-loss, you lose only the sum you decided to risk beforehand.

Divide the amount you are willing to lose by the loss on one unit. Take an account of ₹5,00,000 and a risk of 2%, which is ₹10,000. With an entry at ₹25,00,000 and a stop-loss at ₹23,75,000, each unit loses ₹1,25,000 if the stop is hit. ₹10,000 ÷ ₹1,25,000 is 0.08 units, worth ₹2,00,000 at your entry price.

That is your decision. A common rule of thumb among traders is to risk 1% to 2% of the account on a single trade, so that a run of losing trades does not wipe the account out. It is a convention, not a guarantee, and a smaller figure is more cautious.

It compares what you stand to lose with what you stand to make. With a target of ₹28,75,000 in the example above, the trade could make ₹30,000 against a risk of ₹10,000, a risk to reward of 1 : 3. At that ratio you break even overall, before tax, by winning 25% of trades like it.

Not exactly. Crypto trades around the clock and can move sharply, so a stop-loss order may fill at a worse price than the one you set, and the loss can be larger than planned. Trading with borrowed money raises that risk further. Treat the result as a plan, not a promise.

A loss on one crypto trade cannot be set off against a profit on another, and it cannot be carried forward. Each profitable trade is taxed at 30%, plus cess, on its own, so a mix of wins and losses can leave tax to pay even if you break even overall. Use the India Crypto Tax Calculator for the tax on a sale, and the Crypto Break-Even Calculator for the price that covers fees and tax.
