About Margin Money Requirement Calculator

Margin money is the promoter's own contribution to project cost, the portion the bank will not finance. It must normally be brought in first, since lenders disburse only after the promoter's stake is demonstrably invested.

Formula

Margin money

Loan = project cost × bank share; margin = project cost - loan

Frequently Asked Questions

Why must the promoter contribute first?

It aligns incentives and ensures the promoter has genuine capital at risk before the bank's money is exposed.

Can margin be brought as unsecured loans?

Sometimes, if subordinated to the bank and locked in for the loan's tenor — quasi-equity rather than repayable debt.
