Mortgage Payment by Interest Rate Chart
Monthly principal and interest on a $400,000 30-year loan at every eighth of a point from 3% to 9%, with the lifetime interest beside it. Each quarter point is about $65 a month — and roughly $23,000 across the term.
Source data and formula checked · How we check
Mortgage Payment by Interest Rate Chart reads monthly principal & interest straight off annual interest rate, for 49 values from 3 to 9. Every row is computed from the same formula the calculator uses, not measured or copied from another table, so a value between two rows can be worked out the same way. The formula is the one published by CFPB.
Principal and interest only. Property tax, insurance and PMI sit on top of every figure here.

Questions people actually ask
- How do I read the Mortgage Payment by Interest Rate Chart?
- Find your annual interest rate in the first column and read across. At 3 percent the monthly principal & interest is $1,686.42; at 9 percent it is $3,218.49. The table runs from 3 percent to 9 percent in 49 rows.
- Can I read between two rows?
- Not by splitting the difference. The monthly principal & interest does not change by the same amount from row to row, so the midpoint of two rows is not the answer for the midpoint of two annual interest rate values. Put the exact figure into the calculator instead — it uses the same formula that produced every row here.
- What if my annual interest rate is outside the table?
- The chart covers 3 percent to 9 percent, which is the range people actually look up. Anything above or below goes into the calculator, which takes any figure and shows each step of the working rather than only the result. Open the mortgage payment calculator.
- Where do these numbers come from?
- Every row is computed at build time from the formula published by CFPB, by the same code behind the calculator — not transcribed from another table, which is how a rounding error in one chart ends up in twenty.
Need a different number?
The chart covers the common values. For anything between the rows, the mortgage payment calculator takes any figure and shows the working.
