Overview & Explanation
A mortgage loan calculator computes monthly principal and interest payments over the life of a loan.
How It Works
- Principal P is total property value minus down payment.
- Monthly interest rate i is the annual rate divided by 12 months.
- Total payment count N is loan term in years multiplied by 12.
Practical Applications
- Estimating home affordability and monthly budgeting.
- Comparing 15 year vs 30 year mortgage payment structures.
- Calculating total interest paid over the mortgage duration.
Worked Example: $300,000 Home with 20% Down Payment at 6.5%
