Plain-English explanation
The 30-year and 15-year fixed are the most common. The rate never changes, so your principal and interest payment is predictable for the life of the loan.
Why it matters
Payment stability makes long-term planning easier and protects against rising rates.

A real-world example
A 30-year fixed at 6.5% on $400,000 has a P&I payment of $2,528.27 for every one of the 360 months.
Educational and illustrative only
A common misunderstanding
A fixed interest rate doesn't mean your total monthly payment never changes — escrowed taxes and insurance can still cause it to adjust.
