About Mortgages Calculators

Plan a home loan with free mortgage calculators. Estimate your monthly mortgage payment, what you can afford, refinance savings, amortization, PMI, points, and the difference between a 15- and 30-year term.

Mortgages are the largest loans most people take on, and small rate or term changes move the numbers a lot. These tools let you compare scenarios before you talk to a lender.

Frequently Asked Questions

How is a monthly mortgage payment calculated?
The mortgage payment calculator combines principal and interest (from your loan amount, rate, and term) and can add taxes, insurance, and PMI for a full monthly figure.
Should I choose a 15- or 30-year mortgage?
A 15-year term has higher payments but far less total interest; a 30-year term lowers the payment but costs more overall. The 15-vs-30 comparison calculator shows both side by side.
When does refinancing make sense?
Refinancing helps when the interest saved outweighs the closing costs within your break-even period. The refinance calculator estimates the new payment and break-even point.
