Direct answer

The meaningful comparison is not the new loan rate alone. A home-equity loan preserves the first-mortgage rate but adds a second payment; a cash-out refinance replaces the entire first mortgage at new terms.

Enter figures from current statements, declarations, illustrations or written offers. The result is an auditable scenario, not a quote, approval, recommendation or prediction.

How the calculation works

Each loan uses standard fixed-rate monthly amortization. The keep-first-mortgage route combines remaining first-mortgage interest, home-equity-loan interest and entered fees; the cash-out route combines replacement-loan interest and entered closing costs.

The tool keeps rate, term, fees, limits, valuation and policy assumptions visible so a user can change one input at a time and explain why the result moved.

Worked reference example

At zero interest with equal ten-year terms, 120,000 plus 60,000 produces the same 1,500 monthly debt service under either structure. Fees of 1,000 versus 2,500 create a 1,500 cost difference.

The public fixture reproduces this boundary with deterministic arithmetic. Displayed money rounds to two decimals while the formula engine carries additional precision.

Inputs and documents to collect

Use the latest controlling document for each input. Record its date and whether the amount includes tax, fees, financing, deductibles, other recoveries or a non-guaranteed assumption.

  • Current home value: User-entered planning value; a lender appraisal may differ.
  • Existing first-mortgage balance: Current principal balance.
  • Existing first-mortgage note rate: Contract rate used for the remaining schedule.
  • Existing mortgage months remaining: Scheduled months remaining.
  • Cash needed: Net additional borrowing before entered fees.
  • Home-equity loan rate: Fixed annual rate for the second-loan scenario.
  • Home-equity loan term: Scheduled second-loan months.
  • Home-equity loan fees: Verified cash fees.
  • Cash-out refinance rate: Annual note rate for the replacement mortgage.
  • Cash-out refinance term: Scheduled replacement-loan months.
  • Cash-out refinance fees: Verified cash closing costs; this model does not finance them.

How to interpret the result

Compare written Loan Estimates, APR disclosures, cash-to-close, lien position, tax advice, prepayment terms and whether extending the old balance over a longer term increases total interest.

Compare a base case with at least one adverse case. A smaller payment, lower rate or larger displayed value is not automatically the safer or lower-cost choice when scope, term, security, exclusions or guarantees differ.

Decision checklist

  • Verify every input against a dated document.
  • Keep the comparison horizon and scope consistent.
  • Separate cash paid now from amounts financed or retained.
  • Check a higher-cost or lower-benefit scenario.
  • Save the inputs and result date.
  • Ask the lender, insurer, adviser or regulator about policy-specific exceptions.

Audit the result before using it

Recalculate the reference case before relying on a personal scenario. Then compare each displayed output with a manual reasonableness check: a zero-rate loan should reduce to principal divided by periods, a percentage should reconcile to its numerator and denominator, a limit should never pay more than the entered eligible loss, and a guaranteed column must never absorb a non-guaranteed value. If the official document differs, keep the document as the controlling answer and investigate timing, compounding, rounding, fees, valuation, tax or policy wording.

Record the calculator URL, date, inputs, selected units and source document. That audit trail makes the estimate reproducible and gives a lender, insurer or adviser a precise discrepancy to review.

Limits and when to stop

The tool excludes tax deductibility, approval, credit pricing, points, financed fees, escrow, mortgage insurance, variable rates, recasts, home-equity lines, daily interest and the opportunity cost of cash fees.

Stop and obtain qualified help when legal eligibility, tax treatment, underwriting, a live market rate, policy wording, official valuation or professional judgment controls the answer.

Common mistakes

  • Comparing different horizons or benefit scopes.
  • Treating an estimate as a binding quote or approval.
  • Leaving fees, deductibles, loan balances or non-guaranteed values out.
  • Using a market value where a lender or insurer valuation controls.
  • Assuming a lower payment always means a lower total cost.
  • Failing to retain the source document and calculation date.

Each loan uses standard fixed-rate monthly amortization. The keep-first-mortgage route combines remaining first-mortgage interest, home-equity-loan interest and entered fees; the cash-out route combines replacement-loan interest and entered closing costs. Keep the result label, unit, selected mode, and stated limitations together when sharing the answer.

Frequently asked questions

Why can refinancing be costly even at a lower payment?

Replacing the old balance at a higher rate or stretching it over more years can increase total interest.

Does the tool compare a HELOC?

No. It models a closed-end fixed-rate home-equity loan; revolving HELOC terms need a separate model.
