The SUPRAVAT.IN trading risk calculator is a free online tool that estimates how much money you could lose on a trade before you enter it. By combining your account capital, risk per trade, entry price and stop-loss price, it shows your planned risk amount, risk per unit, position quantity, actual risk, capital allocation and risk/reward ratio — so you can decide whether a trade fits your risk plan.
Why calculating risk before a trade matters
Every trade carries the possibility of loss. A trading risk management calculator helps you size each position so that a single losing trade does not wipe out a large part of your account. Knowing your risk per trade in advance keeps your decisions consistent and removes guesswork from position sizing.
What risk per trade means
Risk per trade is the percentage of your account capital you are willing to lose if your stop-loss is hit. For example, risking 1% of a ₹1,00,000 account means a planned risk of ₹1,000 on that trade. The risk per trade calculator turns this percentage into a concrete rupee amount.
How account capital affects planned risk
Planned risk is calculated directly from your account capital and risk percentage. A larger account produces a larger planned risk amount for the same percentage, while a smaller account produces a smaller one. The percentage stays the planning constant, not the rupee value.
How entry and stop-loss determine risk per unit
Risk per unit is the distance between your entry price and your stop-loss price. For a Long trade it is entry minus stop-loss; for a Short trade it is stop-loss minus entry. A wider stop increases risk per unit, while a tighter stop reduces it. This value is the foundation of the stop loss risk calculator.
How quantity affects total risk
Total risk is risk per unit multiplied by the quantity you trade. Trading more units increases the amount at risk, while trading fewer units reduces it. The position risk calculator balances quantity against your planned risk so the trade stays within your intended limit.
Planned risk vs actual risk
Planned risk is the amount you intend to risk, based on your capital and risk percentage. Actual risk is the risk per unit multiplied by the final quantity you actually trade. Because quantity is rounded down to whole units, actual risk can be slightly below or above planned risk, and the risk utilization figure shows how closely they match.
Position value vs amount at risk
Position value is the total capital used to enter the trade (entry price × quantity). Amount at risk is the money you would lose if the stop-loss is hit. A trade can have a large position value but a small amount at risk when the stop-loss sits close to the entry price — these are two different numbers that should not be confused.
How manual quantity mode works
In manual quantity mode you enter the quantity yourself and the calculator shows the actual risk, actual risk percentage, position value, capital allocation, potential profit and risk/reward for that quantity. This is useful for checking the trading position risk of a position you have already selected or are considering.
How risk-based quantity mode works
In risk-based mode the position sizing calculator works out a whole-unit quantity from your account capital, risk percentage, entry price and stop-loss price. It also checks the capital maximum quantity you can afford, so the practical quantity never exceeds what your capital allows.
How target price is used for potential profit and Risk/Reward
When you enter a target price, the risk reward calculator finds the target distance, potential profit, potential profit percentage, potential return on risk and the risk/reward ratio. The target is optional — without it the calculator still shows all risk figures, just without the reward analysis.
Why Long and Short calculations are different
A Long trade profits when price rises, so the stop-loss sits below the entry and the target sits above it. A Short trade profits when price falls, so the stop-loss sits above the entry and the target sits below it. The stock risk calculator applies the correct direction to every distance and validation check.
Why whole-unit rounding can slightly change actual risk
Most markets trade in whole units, so a fractional calculated quantity is rounded down to a practical whole quantity. Because actual risk and potential profit use this practical quantity rather than the raw calculated value, the final numbers can differ slightly from the planned risk. The rounding transparency note explains this for every trade.
