Compare calculators
Both calculators run independently — change the inputs on either side to compare results.
Loan Amortization Calculator
Calculate the periodic payment on an amortizing loan given the principal, annual interest rate, term in years, and payment frequency. Use it for any fully-amortizing fixed-rate loan — mortgage, auto, student, personal — where each payment is the same and the balance reaches zero at the end.
Mortgage Payment Calculator
Estimate the full monthly cost of owning a home — principal, interest, property tax, and homeowner's insurance — bundled into the single number lenders call PITI. Enter your loan amount, interest rate, loan term in years, annual property tax, and annual home insurance, and the calculator returns the monthly payment you would actually send (excluding PMI and HOA fees, which vary widely). This is the figure to compare against your monthly budget when deciding whether a home is affordable, and the figure mortgage lenders use to qualify you against debt-to-income limits.
