Margin Calculator
Estimate the capital required for a leveraged position and see how leverage changes your modeled exposure.
Position assumptions
Enter the position you want to model.
Estimated requirement
Updates automatically as you change an input.
At 5x leverage, the model uses one 5th of the position value as the upfront margin.
Margin = position value ÷ leverage
The calculator first multiplies share price by quantity to get the modeled position value. It then divides that value by the leverage entered.
Example: a ₹1,00,000 position at 5x leverage gives a modeled margin requirement of ₹20,000.
What this calculator does not model
- Broker-specific margin rules
- Maintenance margin and liquidation thresholds
- Exchange haircuts or product-specific exposure limits
- Overnight versus intraday margin differences
How to use the Margin Calculator
Use this calculator for a first-pass estimate of the capital represented by a leveraged position. It uses share price, quantity and a leverage multiple; it does not connect to a broker or retrieve live margin rules.
1. Enter the position value
Enter the price per share or unit and the quantity you want to model. The calculator multiplies them to estimate total position value. For example, 100 shares at 100 each represent a position value of 10,000 in the selected currency.
2. Enter the leverage multiple
Enter the leverage assumption, such as 5x. In this simplified model, margin required equals position value divided by leverage. A 10,000 position at 5x therefore gives an estimated margin of 2,000 before any broker-specific requirements or fees.
3. Compare scenarios carefully
Keep price and quantity unchanged while testing different leverage values to see how the modeled margin changes. Then consider the full position value and the loss that could result from an adverse price move—not just the amount of capital shown as required margin.
Understand the result
Margin required is the calculator's simplified upfront capital estimate. Total position value is price multiplied by quantity. Exposure / margin shows the position value relative to the modeled margin; it is an arithmetic ratio, not a risk score or a broker's buying-power promise.
Important limitations
Real margin requirements may include minimums, maintenance margin, exchange or broker haircuts, contract multipliers, portfolio offsets and different intraday or overnight rules. This page does not estimate liquidation prices, funding costs, transaction charges or the maximum loss of a trade. Confirm the applicable rules with your broker before placing an order.
Margin Calculator FAQs
What is margin in trading?
Margin is the capital a broker requires to open or maintain a leveraged position. It is not the same as the full value of the position, and the exact requirement depends on the broker, instrument, exchange and current risk controls.
How is required margin calculated here?
The calculator multiplies share price by quantity to estimate position value, then divides that value by the leverage entered. This simplified formula is for illustration and may not match a broker's actual margin calculation.
How does leverage affect required margin?
Under this model, a higher leverage multiple lowers the upfront margin for the same position value. It does not lower the market exposure: gains and losses still relate to the full position, so a small price move can have a larger effect relative to your margin.
What is the difference between margin and position value?
Position value is the total market value represented by the trade (price multiplied by quantity). Margin is the portion of capital assumed to support that position in this calculator.
Does this show my broker's actual margin requirement?
No. Brokers can apply product-specific rules, minimums, maintenance margin, haircuts, concentration limits and intraday or overnight policies. Check the broker's current order or margin calculator before trading.
Can I use this for futures, options or forex?
You can use the arithmetic as a rough illustration, but derivatives and foreign-exchange products often use contract multipliers, premium rules, portfolio offsets or risk-based margin. This calculator does not model those details.
Can margin requirements change after I open a position?
Yes. Brokers or exchanges may change requirements as volatility, liquidity, concentration or product rules change. You may need to add funds or reduce exposure if the available margin becomes insufficient.
Does lower margin mean a trade is safer?
No. Lower modeled margin means more exposure relative to the capital committed. Leverage can magnify losses and may lead to forced position reduction or liquidation under broker rules.
