15 vs 30 Year Mortgage Calculator
The monthly cost of a shorter term against the lifetime interest it removes.
How this number is built
Doing it by hand
Step 1
Get quotes for both terms on the same day — the spread between them moves.
Step 2
Check the 15-year payment against your budget with tax and insurance included.
Step 3
Compare total interest, which is where the shorter term wins decisively.
Step 4
Model investing the payment difference at a return you would realistically achieve.
Step 5
Consider a 30-year loan paid on a 15-year schedule if you want the flexibility.
What people ask next
Why is the 15-year rate lower?
Shorter loans carry less interest-rate and default risk for the lender, so they price below 30-year paper.
What if my income is variable?
A 30-year loan with voluntary extra payments gives you the same outcome with an escape hatch in a bad month.
