Frequently asked questions
Complete guide to Mortgage Calculator
What is a mortgage calculator?
A mortgage calculator estimates your monthly payment (principal and interest) for a home loan. Enter the loan amount, interest rate, and term (e.g. 30 years). Some calculators also include property taxes, insurance, and PMI. Use it to see how much you will pay each month and how much total interest you will pay over the life of the loan.
What affects your mortgage payment?
- Loan amount: Larger principal means higher EMI.
- Interest rate: Even 0.5% can change your payment and total cost significantly.
- Term: 15-year loans have higher monthly payments but much less total interest than 30-year.
- Property taxes and insurance: Often paid via escrow; add to your budget.
- PMI: Required if down payment is below 20%; adds to monthly cost until you reach 20% equity.
Fixed vs adjustable rate
Fixed-rate mortgages keep the same rate for the full term; your principal and interest payment stays constant (excluding tax/insurance changes). Adjustable-rate (ARM) loans start with a lower rate that can change after an initial period. Use this calculator with different rates to compare 15-year vs 30-year and fixed vs ARM scenarios.
