Loan Refinancing Break-Even Analysis via AI

Refinancing break-even analysis calculates the exact point in time at which the monthly savings from a lower interest rate offset the upfront costs of refinancing — closing fees, origination charges, and prepayment penalties — making it the critical decision gate before committing to a new loan. Without this calculation, borrowers often refinance into deals that cost more than they save over their actual ownership horizon.

AI makes this analysis accessible to anyone by translating plain-language descriptions of a loan situation into a clear month-by-month payback model, removing the need for financial calculators or spreadsheet expertise.

How to apply it

Ask Claude: 'I have a $280,000 mortgage at 7.1% with 24 years remaining. I was offered a refinance at 6.4% with $6,500 in closing costs. I plan to stay in this home for at least 5 more years. Calculate my monthly savings, the break-even month, total interest saved if I stay 5 years vs 10 years, and whether this refinance makes financial sense.' You'll get a clear go/no-go recommendation with supporting math.
