About Mortgage Calculator & Amortization Schedule

Purchasing real estate is typically the single largest financial transaction in a person's life. ConvertSheet's Mortgage Calculator computes comprehensive PITI (Principal, Interest, Taxes, and Insurance) plus Private Mortgage Insurance (PMI) for loans with down payments below 20%. Unlike static calculators, this tool allows you to simulate extra monthly principal contributions to calculate interest saved and years shaved off your loan, with instant one-click export of the entire amortization table to Microsoft Excel (.xlsx) using SheetJS.

Mathematical Formula & Algorithm:Monthly P&I = P * [r(1+r)^n] / [(1+r)^n - 1], where P = Principal Loan Amount, r = Monthly Interest Rate (Annual Rate / 12), and n = Total Number of Payments (Months).

Frequently Asked Questions: Mortgage Calculator & Amortization Schedule

Answers to common questions regarding inputs, calculations, and mathematical methodology.

What is included in a PITI mortgage payment?

PITI stands for Principal, Interest, Taxes, and Insurance. It represents the comprehensive monthly housing payment escrowed by your mortgage servicer, including local property taxes and hazard insurance.

When does PMI (Private Mortgage Insurance) drop off?

PMI is automatically required on conventional loans when down payment is under 20% (loan-to-value > 80%). Under the Homeowners Protection Act, PMI drops off automatically once principal amortizes down to 78% of the original purchase value.

How does an extra monthly principal payment shorten the loan?

Every dollar paid in excess of your required monthly payment directly reduces the outstanding loan balance. Because interest is compounded on the remaining balance, paying extra accelerates equity buildup and saves thousands in cumulative interest.

Can I open the exported amortization schedule in Microsoft Excel or Google Sheets?

Yes! The exported .xlsx file is fully compatible with Microsoft Excel, Apple Numbers, Google Sheets, and LibreOffice Calc.
