**Formula**

The calculator employs the standard mortgage formula to determine monthly payments:

$M=P×(+r)n−r(+r)n $

Where:

- $M$ is the monthly mortgage payment.
- $P$ is the principal loan amount.
- $r$ is the monthly interest rate (annual rate divided by 12).
- $n$ is the total number of payments (loan term in months).

**Example**

Let’s consider a $300,000 mortgage with a 4% annual interest rate.

For a 30-year term: $n=30×12=360$

For a 15-year term: $n=15×12=180$

**FAQs**

**Q: Why should I consider a 15-year mortgage over a 30-year mortgage?**

A: A 15-year mortgage typically has a lower interest rate and results in substantial interest savings over the life of the loan.

**Q: Will my monthly payments be higher with a 15-year mortgage?**

A: Yes, monthly payments will be higher, but you’ll pay less interest over the life of the loan.

**Q: Can I switch from a 30-year to a 15-year mortgage?**

A: Some lenders allow refinancing, but it’s essential to consider associated costs and eligibility.
