Loan & Mortgage Math: Monthly Payments and Interest Explained
Loan amount, annual rate, and term decide your monthly payment. With equal installments, the payment is fixed — more interest is paid early, more principal later.
Loan vs Mortgage
- Loan Calculator: enter amount, rate, term for instant monthly payment
- Mortgage Calculator: also factors down-payment ratio and loan term
- Both show total interest, making comparison easy
Using the result to decide
Compare the monthly payment against your income — keeping it under half is a common rule. A bigger down payment or shorter term saves interest but raises the monthly payment.
💡 Shortening the term by 5 years often saves tens of thousands in interest — run the calculator before signing.
