Refinance Calculator

Compare keeping your current mortgage with replacing it. See principal-and-interest payments, closing costs and points. Full-term interest totals cover different periods when loan terms differ, not a same-horizon savings estimate.

Refinance summary

The modeled monthly principal-and-interest payment is $334 lower. That is a payment difference, not overall savings. Fees, how long you keep the loan and the balance still owed matter, especially when the terms differ.

Monthly payment

Current payment (P&I)$2,253
New payment (P&I)$1,920
Monthly savings$334

Cost to refinance

Closing costs$4,500
Discount points$0
Total cost of refinance$4,500
Cash at close$0
New loan amount$324,500

Same-period payments and remaining debt

yrs

How long you expect to keep the loan. No sale costs, tax effects or discounting are modeled.

Keep loan: payments in period$135,205
Keep loan: debt still owed$296,935
Replace loan: payments in period$115,172
Replace loan: debt still owed$301,491
Replace loan: cash fees at closing$0

Compare both payments and remaining debt. Financed closing costs and points are already in the new loan balance, not an additional cash payment. These figures do not select a winner.

Separate full-term interest totals, not comparable savings

Remaining interest on current loan$410,108
Total interest on new loan$366,534
Difference-$43,574
Total cost over new loan term$691,034

A lower monthly payment can still mean more total interest if the new term is longer than what you have remaining. Use the Break-Even Calculator to see how long it takes to recover the refinance cost.

Results are estimates based on user inputs and do not represent loan terms, APR, or a financing offer. Pre-filled values are illustrative examples, not available or quoted rates. Actual terms depend on credit, property, program, and underwriting. Every result applies to the entered planning scenario, not an observation period or local market statistic. Replace price, tax, insurance and fee allowances with dated, property-specific figures. Missing inputs are not assumed to be zero.

Frequently asked questions

How do I know if a refinance is worth it?
Two questions: does it save you a meaningful amount per month, and will you stay in the home long enough to recoup the closing costs? If both answer yes, the math usually works.
What's a typical break-even point on a refinance?
Most refinances break even in 2–4 years depending on closing costs and the rate drop. If you'll be in the home longer than that, the refinance generally pencils.
Does refinancing reset the loan?
Yes. A refinance starts a new loan with a new term. If you refinance into another 30-year, you reset the clock, which can mean more lifetime interest even at a lower rate. Compare carefully.
