Mortgage & loan calculator
Fixed-rate amortization — monthly payment and full schedule.
What the estimate really shows
Mortgage calculations are most useful when you want a realistic sense of principal and interest before you contact a lender. For example, a $300,000 loan at 4.5% over 25 years gives you a rough monthly payment that can anchor your housing budget.
Costs outside the calculator
Remember that taxes, insurance, maintenance, and HOA dues are separate from the loan payment itself. That means the number here is a strong planning signal, but not a complete monthly housing bill, especially in markets where property taxes vary widely.
Example scenario
A $300,000 loan at 4.5% over 25 years produces roughly $1,667 per month in principal and interest alone — taxes, insurance, and HOA fees sit outside this calculator.
How mortgage math works here
Enter principal, APR, and term in months or years. The calculator amortizes equal payments when classic formulas apply and lists how much goes to interest over time.
Use it to compare scenarios — shorter terms raise payments but cut total interest.
Disclaimers
Does not include escrow, insurance, PMI, or regional taxes. Lenders may quote different APR conventions.
