How it works
We compute total interest for scenario A and B using the standard formula. Savings = interest A − interest B.
When to use it
Use it to see savings from a refi, from paying extra, or from choosing a shorter term.
Frequently asked questions
What if I pay extra?
Use the mortgage payoff calculator to model extra payments.
Include closing costs?
No. Subtract refi costs from interest savings for net benefit.
