Measure affordability using income, equity, and debt. Compare payment shifts, closing costs, and cash-out limits. Plan refinancing decisions with clearer numbers before signing anything.
| Scenario | Total Monthly Income | Property Value | Current Balance | New Rate | Cash-Out | Estimated New Housing Cost |
|---|---|---|---|---|---|---|
| Primary Home Refi | $11,000 | $425,000 | $255,000 | 5.75% | $20,000 | $2,224.00 |
| Low Debt Case | $9,200 | $390,000 | $210,000 | 5.60% | $10,000 | $1,860.00 |
| Higher Equity Case | $13,400 | $560,000 | $280,000 | 5.50% | $40,000 | $2,425.00 |
These rows are sample planning figures that show how different income, balance, and equity levels can affect refinance affordability.
M = P × [r(1 + r)^n] ÷ [(1 + r)^n - 1]
Max Housing = (Total Monthly Income × Max DTI) - Monthly Debts
Max P&I = Max Housing - Taxes - Insurance - HOA
New Loan = Current Balance + Cash-Out + Financed Closing Costs
LTV = New Loan ÷ Property Value × 100
Break-Even = Closing Costs ÷ Monthly Savings
This calculator combines debt-to-income limits, property equity limits, refinance payment math, and closing-cost recovery timing to estimate how much refinance loan you can reasonably support.
You can usually afford the cash-out amount that still keeps your new monthly housing cost inside your target debt-to-income ratio and keeps your new loan below the lender’s loan-to-value cap. In practice, affordability depends on income, debts, rate, term, equity, and closing costs together.
It estimates whether your income can support a refinance after counting debts, taxes, insurance, HOA, loan size, rate, term, and any cash-out request.
Usually, the affordable amount is the highest cash-out that keeps your payment within DTI limits and your new balance within the allowed LTV cap.
DTI ratios show how much of your income already goes toward debt. Lower ratios generally leave more room for a lender to approve the new payment.
Home value affects your equity and your LTV ratio. Higher value can increase the maximum loan size and potential cash-out room.
Financing closing costs reduces upfront cash needs, but it raises the new loan balance and can slightly increase the monthly payment and interest paid.
Break-even time estimates how many months of monthly savings it takes to recover your closing costs. A shorter period usually improves refinance value.
A longer term often lowers the monthly payment, which can help affordability, but it may increase the total interest paid over time.
No. It is a planning estimate. Lenders may still review credit, appraisal results, reserves, occupancy, loan program rules, and documentation quality.
