EMI, total interest and the full amortization schedule — with moratorium support and PDF / Excel export.
The EMI (Equated Monthly Installment) on a reducing-balance loan is computed with the standard annuity formula: EMI = P × r × (1 + r)n / ((1 + r)n − 1), where P is the principal, r the monthly interest rate (annual rate ÷ 12) and n the number of months. Each month's payment first covers the interest on the outstanding balance; the remainder reduces the principal — so the interest component falls and the principal component rises over the tenure. The EMI is rounded to the nearest rupee, and the final installment adjusts so the closing balance is exactly zero.
A moratorium is a payment holiday at the start of the loan — common for education loans, project loans and construction-linked disbursements. It defers payments, but it is never free: in a full moratorium no payments are made and the accrued interest is added to the principal each month (it compounds monthly, the way banks apply it), so EMIs are later computed on a larger amount. In an interest-only moratorium you pay the interest as it accrues and the principal stays unchanged — cheaper overall than full deferral, but with a monthly outgo from day one. The schedule above shows the moratorium months separately so both effects are visible.
