Assumptions & Limitations

What the calculation assumes

  • Rates and contributions are assumed to stay constant for the whole period unless the form asks for them separately.
  • Results use standard financial formulas and ignore fees, penalties and promotional terms that are not entered above.
  • Inflation, tax changes and market volatility are not modelled unless a field for them is provided.
  • Amounts are unit-agnostic: results are returned in the same currency you enter.

What it does not cover

  • Real-world outcomes differ when fees, taxes, rounding rules or provider-specific terms apply.
  • Local regulations and tax rules vary by country and change over time; verify current rules for your jurisdiction.
  • Figures are only as accurate as the inputs you supply — check them before acting on the result.
  • For decisions with lasting financial impact, confirm the numbers with a qualified professional.

Frequently Asked Questions

Upfront closing costs (origination fees, appraisal, title insurance, escrow) represent the financial hurdle you must clear. Dividing total upfront costs by monthly payment savings reveals the exact months needed to turn a net profit.

If you refinance with $4,000 in closing costs to save $100 per month (40-month break-even) and sell the home after 24 months, you recoup only $2,400 of savings, resulting in an unrecoverable net loss of $1,600.

Financing closing costs eliminates out-of-pocket expenses on closing day, but increases your new principal balance. This reduces your monthly savings and incurs long-term interest on the fees themselves.

No. While you must fund a new escrow account on the new loan, your previous servicer must refund your remaining old escrow balance within 30 days, making escrow a cash-flow timing event rather than a permanent closing cost.
