What this calculator estimates
Estimate potential reverse-mortgage proceeds using an editable principal-limit assumption.
How to use it
Enter Home value ($); Estimated principal limit (%); Existing mortgage payoff ($); Estimated upfront costs ($). Select Calculate to update the results.
How the calculation works
Illustrative gross principal limit = entered home value × assumed principal-limit percentage/100. Subtract the existing mortgage payoff and upfront costs. Available proceeds are shown as zero if these deductions exhaust or exceed the gross limit.
Worked example: starting scenario
| Home value ($) | 500000 |
|---|---|
| Estimated principal limit (%) | 45 |
| Existing mortgage payoff ($) | 80000 |
| Estimated upfront costs ($) | 12000 |
| Estimated net proceeds | $133,000.00 |
|---|---|
| Estimated gross borrowing limit | $225,000.00 |
| Mortgage payoff | $80,000.00 |
| Upfront costs | $12,000.00 |
Important limitations
The percentage is a user assumption, not an age-and-rate-based HECM limit calculation. The model does not apply lending limits, required set-asides, initial-disbursement restrictions, eligibility or payment-option rules. A zero result can indicate a shortfall; it does not mean the loan can close without additional funds.
