FHA Streamline
What are the two ways to use a lower rate?
A lower rate lowers the payment your loan requires. You can keep that difference as monthly cash flow, or send it to principal to pay off sooner — both are legitimate, and neither is automatically better.
A lower interest rate lowers the payment your loan requires each month. That gap between your old payment and the new required payment is money you get to decide how to use, and there are two clear paths. Path one — keep the monthly savings — takes that difference as extra cash flow every month; the interest you save comes purely from the lower rate itself. Path two — keep paying what you pay today — sends that same difference straight to principal, so you get the lower-rate savings and additional interest saved from paying the balance down faster, and you reach payoff sooner. Neither path is objectively superior: the first helps your monthly budget, the second reduces total interest and shortens the loan. What matters is which fits your goals. The calculator shows both side by side using your real numbers, and keeps the two sources of interest savings separate so nothing is double-counted.
Two ways to win
A lower interest rate lowers the payment the loan requires. What you do with that difference is your choice — and both choices are worth something.
Keep the savings
Lower your required payment and keep the difference as monthly cash flow.
- A lower required monthly principal & interest payment.
- More money available every month to use however you choose.
- Lifetime interest savings created by the lower rate itself.
Keep the payment
Keep paying roughly what you pay today and send the difference to principal.
- More of each payment reaches principal at the lower rate.
- Fewer remaining payments and an earlier payoff date.
- The lower-rate savings plus extra interest saved from faster paydown.
