Finance Calculators
EMI Calculator
Estimate a fixed monthly installment, scheduled interest, total payments, and reconciled amortization.
Fixed-rate monthly installment estimate
Estimate a regular month-end payment from principal, a nominal annual rate, and a term in months or years.
Principal borrowed before interest, fees, insurance, or taxes.
Divided by 12 to produce the monthly rate.
The selected term must convert to 1 through 600 whole monthly payments.
Calculation assumptions
- *Models a fixed-rate, fully amortizing principal-and-interest schedule with payments at month-end.
- *The nominal annual rate is divided by 12; daily accrual and irregular payment periods are not modeled.
- *Internal balances remain unrounded. Currency displays use cents, and the final payment is reconciled to zero.
- *Fees, insurance, taxes, prepayments, penalties, rate changes, and lender-specific rules are excluded.

EMI formula and payment convention
The calculator uses EMI = P x r x (1 + r)^n / ((1 + r)^n - 1). P is principal, r is the nominal annual rate divided by 12, and n is the number of month-end payments. At a zero rate, EMI equals principal divided by n.
Interest for each period is calculated from the unrounded opening balance. The remaining payment reduces principal, and the final payment absorbs any sub-cent remainder so the ending balance is zero.
Verified installment examples
A $100,000 principal at a 12% nominal annual rate for 12 months produces a regular EMI of about $8,884.88. The first payment includes $1,000.00 of interest and about $7,884.88 of principal. Total scheduled interest is about $6,618.55.
A $500,000 principal at 10% for 60 months produces a regular EMI of about $10,623.52 and about $137,411.34 of total scheduled interest under the same month-end convention.
EMI scope and limitations
EMI is the regular principal-and-interest installment for the modeled fixed-rate schedule. It does not include fees, insurance, taxes, penalties, optional products, or changing rates.

Frequently Asked Questions
Common questions about EMI Calculator and how to read the result.
What is included in this EMI?
The estimate includes scheduled principal and interest only. It excludes fees, insurance, taxes, penalties, prepayments, and lender-specific charges.
How is the monthly rate calculated?
The entered nominal annual rate is divided by 12. The calculator does not model daily accrual or irregular payment periods.
Why can the final payment differ slightly?
Calculations keep unrounded balances internally. The final payment is reconciled for any sub-cent remainder so total principal paid matches the original principal.
Is this EMI a lender quote or approval?
No. It is an educational fixed-payment estimate. Actual lender disclosures may include different timing, fees, rates, or other terms.
