A Tennessee mortgage refinance calculator that shows how many months it takes for a lower rate to recover the closing costs of refinancing your Tennessee home loan, plus your monthly saving and lifetime interest saved over the remaining term.
How it works
The tool prices your current loan and the proposed new loan over the same remaining term using the standard amortization formula M = P · r ⁄ (1 − (1 + r)⁻ⁿ), where P is your balance, r is the monthly rate (annual rate ÷ 12 ÷ 100), and n is the number of months remaining. It computes the payment at your current rate and at the new rate, then:
monthly saving = old payment − new payment
break-even months = closing costs ⁄ monthly saving
lifetime savings = monthly saving × remaining months − closing costs
The break-even is rounded up to a whole month. If the new rate does not lower your payment, there is no saving and no break-even.
Example
A $350,000 Tennessee balance with 30 years remaining, refinancing from 6.75% to 5.50% with $5,000 in closing costs:
- Payment at 6.75%: about $2,270/month
- Payment at 5.50%: about $1,987/month
- Monthly saving: about $283
- Break-even: $5,000 ÷ $283 = about 18 months
- Lifetime savings over the remaining term: about $96,819
If you expect to keep the Tennessee loan well beyond the 18-month break-even, the refinance puts you ahead; if you plan to sell sooner, it may not be worth it.
Notes
Estimate only — not financial or tax advice. Actual Tennessee refinance costs, rates, and terms depend on your lender, credit, loan-to-value, and current market conditions. Verify figures with your county recorder and the Tennessee Department of Banking/Insurance (or equivalent state regulator) and the Consumer Financial Protection Bureau (CFPB) before deciding.
