How much can I save with extra payments?
A mortgage savings simulation models how extra payments, refinances, or rate changes alter the total cost of your loan. The most impactful variables are extra monthly payments and refinancing into a lower rate — each can save tens of thousands in interest over a 30-year term.

Based on a $200,000 loan at 7.5% for 30 years (base payment: $1,398/month):
| Extra/month | You save | You finish |
|---|---|---|
| $100 | ~$43,000 | ~2 years early |
| $300 | ~$86,000 | ~4 years early |
| $500 | ~$121,700 | ~5 years 7 months early |
| $1,000 | ~$160,000 | ~8 years early |
Even $100/month extra has a massive impact because compound interest works against you over decades.
