Method

Exposure = price × quantity. Required margin = exposure ÷ leverage. Displayed financed amount = exposure−required margin. Funds surplus or shortfall = available funds−required margin. A leverage input below 1 gives a negative financed figure because required funds then exceed the exposure; this is not borrowing.

How this calculation works

Translate a trade’s notional value and an entered leverage multiple into a simple funding requirement. The surplus or shortfall compares that required margin with the cash you say is available. It is not an exchange-approved margin quote or a liquidation-price calculation.

Exposure = price × quantity. Required margin = exposure ÷ leverage. Displayed financed amount = exposure−required margin. Funds surplus or shortfall = available funds−required margin. A leverage input below 1 gives a negative financed figure because required funds then exceed the exposure; this is not borrowing.

Worked example

This example uses illustrative inputs. Your current result is shown above.

For 100 units at ₹1,000 with 5× leverage and ₹25,000 available funds, exposure is ₹1,00,000. Required margin is ₹20,000, implied financing is ₹80,000 and the available-funds surplus is ₹5,000.

Assumptions and limits

  • One constant leverage multiple applies to the entire position.
  • Available funds are assumed to be usable for this trade without collateral haircuts or other blocked balances.
  • Broker and exchange rules, maintenance margins, financing costs and price-change risk are not simulated.

Questions people ask

Does a positive surplus mean the broker will accept the order?

No. It only clears this arithmetic requirement. Instrument eligibility, collateral rules, other positions and the broker’s current margin system can change the required funds.

Does leverage reduce the size of a trading loss?

No. The exposure remains price multiplied by quantity. This calculator reduces the upfront funding estimate, not the notional amount whose price can move.
