Method

For principal P, nominal annual percentage A, f payments per year and n payments, r = A ÷ (100f). Reducing-balance payment E = P × r ÷ [1 − (1 + r)^(−n)], or P ÷ n at 0%. Flat payment E = P × [1 + (A ÷ 100) × (n ÷ f)] ÷ n. Total repayment = nE + separately paid fee F; interest and fees = nE + F − P. Monthly loans use f = 12 and n = 12 × years, or the entered number of months. F is zero where no fee is entered. In reducing mode, interest in period t = opening balance × monthly rate; principal repaid = payment − interest; closing balance = opening − principal repaid. In flat mode, monthly interest = original P × annual percentage ÷ 1,200. The final principal payment is capped at the remaining balance.

How this calculation works

Inspect how each scheduled instalment is divided between interest and principal. The EMI can stay level while the interest share changes because reducing-balance interest is charged on the opening balance. The month-by-month table makes the outstanding amount at an intermediate date visible. Flat mode instead keeps monthly interest based on original principal, so its schedule has a different shape.

Worked example

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

For ₹1,20,000 at 12% annual reducing-balance interest for one year, EMI is ₹10,661.85. First-month interest is ₹1,200 and principal reduction ₹9,461.85, leaving ₹1,10,538.15. Total interest across the twelve-payment schedule is ₹7,942.26; schedule totals retain unrounded internal values.

Assumptions and limits

The rate, payment interval and interest method stay constant, with no missed or extra instalments.
The schedule excludes fees and actual calendar day counts. Currency displays may not sum exactly when individually rounded rows are added.

Questions people ask

Why is first-month principal less than the EMI?

Part of the payment settles interest accrued on the opening balance. Only the remainder reduces the amount owed.

Can I insert a part payment into this schedule?

No. Use Loan Prepayment to model a selected lump sum after scheduled instalments and compare lower EMI with shorter tenure.
