Reading your home equity loan payoff numbers
The payoff date and total interest figures above assume your rate and required payment stay fixed for the life of the loan, which matches a standard home equity loan. They're planning estimates. The number that actually settles the loan is the payoff quote your servicer hands you on the day you pay it off.
If you're deciding between extra payments and a refinance, run both. Use the calculator with extras to see the new total interest, then run the refinance scenario with the new rate, the new term, and closing costs added to the new principal. Compare the two total-interest figures. A lower monthly payment from a refinance can hide more total interest when the term resets.
Rolling the home equity loan into a new first mortgage is a separate decision and not the same trade. It can simplify billing and lower the monthly outflow, but it usually stretches the payoff window — total interest can rise even at a lower headline rate. If you go that route, compare total interest over your realistic time horizon in the home, not just the new payment.
Worked example: $60,000 fixed home equity loan at 8.5% over 15 years
Run the calculator above with those inputs. The scheduled monthly payment lands near $591 and total interest over the full 15 years lands near $46,400. That's the no-extras baseline.
Now add $100 a month from the start. The payoff accelerates by roughly two and a half years and total interest drops by about $6,500. The dollar amount looks small per month but compounds because each extra payment removes principal that future interest would otherwise be charged on.
The harder comparison isn't extra payments versus schedule — the calculator shows that clearly. It's extra payments versus a refinance versus rolling the balance into a new first mortgage. A refinance only wins if the new rate, after closing costs, beats the interest you would have paid by simply adding extra. Rolling the same $60,000 into a fresh 30-year first mortgage usually lowers the monthly payment but extends the debt — total interest can rise even at a lower rate. Run each scenario in the calculator and compare total interest, not just the new monthly payment.
Five things to know about home equity loan payoff
Fixed second mortgage, not a HELOC
A home equity loan is usually a one-time lump sum with a fixed rate and a fixed monthly payment for a set term. A HELOC is a revolving line of credit with separate draw and repayment phases, often at a variable rate. This calculator is built for the fixed loan. If your statement shows a draw period or available credit, use the HELOC payoff calculator instead.
A predictable payment is not a cheap payoff
Fixed payments make the math simple — they don't make the loan small. Interest paid over a 10- or 15-year term still adds up to a meaningful share of the loan, especially at current home-equity rates. Run the calculator with and without extra principal to see what you'd actually save.
Closing costs can erase a refinance win
Home equity loans typically come with origination, appraisal, title, and recording fees, often quoted in the 2–5% range. On a smaller balance, those costs can wipe out the savings from a slightly lower rate. Compare total cost — closing costs plus future interest — not just the new monthly payment.
Interest deduction depends on use of funds
Under current IRS rules (Publication 936), interest on a home equity loan is generally deductible only when the funds were used to buy, build, or substantially improve the home that secures the loan. Funds used for tuition, debt consolidation, or other purposes generally are not deductible. Verify your specific situation with a tax professional.
Payoff quote vs statement balance
The statement balance reflects what you owed at the last billing date. A payoff quote includes interest accrued since then, any per-diem to a chosen payoff date, and any servicer or prepayment fee. If you're sending a final payment, ask your servicer for a written payoff quote good through a specific date.
A fixed second mortgage, not a HELOC
A home equity loan is usually a one-time lump sum at closing with a fixed rate and a fixed monthly payment over a set term. From the math side it behaves like a smaller, shorter mortgage — predictable amortization, no phase-transition surprises. A HELOC is a different product: a revolving line of credit with a draw period and a separate repayment period, often at a variable rate. The same payoff calculator can't honestly model both. This page is built for the fixed loan.
Because the math is clean, the homeowner's decision is rarely 'how does the schedule work.' It's 'what should I do with extra cash.' Three options, in plain order: keep paying the schedule and use the extra dollars somewhere else; add extra principal each month to shorten this loan; or refinance — either into a new home equity loan or by rolling the balance into a new first mortgage. The calculator above answers the first two. The refinance question depends on the new rate, the new term, and the closing costs added to the new principal.
Two practical notes that change the call. Closing costs can erase the benefit of refinancing a smaller balance — a $30,000 home equity loan with $1,500 in closing costs has to recover those costs through monthly savings before the refinance starts paying for itself, which can take years. And a home equity loan sits in second position behind your primary mortgage. For planning the payoff, second position mostly shows up in the loan's pricing relative to first-mortgage rates; it doesn't change the schedule the calculator computes.
Frequently asked questions
Is a home equity loan the same as a HELOC?
No. A home equity loan is a fixed-rate, lump-sum second mortgage with a predictable monthly payment and a fixed payoff date. A HELOC is a revolving line of credit, often variable-rate, with separate draw and repayment phases. The math on the loan version is closer to a regular mortgage; the HELOC has its own phase-transition behavior. Use the HELOC payoff calculator if your statement shows a draw period or available credit.
Do home equity loans have prepayment penalties?
Many lenders do not charge one, but practices vary by lender and by state. Some loans include a small fee for paying the balance off in the first few years. Read the note that came with your loan documents, or call your servicer and ask whether a prepayment fee applies before you send a large lump sum.
Should I refinance my home equity loan or just pay extra?
It depends on the new rate, the new term, the closing costs on the new loan, and how long you plan to keep the home. Refinancing into a lower rate only saves money if the rate reduction beats the closing costs over your realistic time horizon. Adding extra principal each month avoids closing costs entirely and accelerates the original schedule. Run both scenarios in the calculator and compare total interest, not just the monthly payment.
Should I roll my home equity loan into a new first mortgage?
Rolling the balance into a new first mortgage can lower the combined monthly payment by stretching the debt over a longer term, but total interest can rise. It can also change the tax picture — under IRS Publication 936, interest on cashed-out funds is generally deductible only when used to substantially improve the home. Compare total interest over your realistic time-in-home, not just the new payment, and verify the deductibility question with a tax professional.
Is my home equity loan interest tax-deductible?
Under current IRS rules (Publication 936), interest on a home equity loan is generally deductible only when the funds were used to buy, build, or substantially improve the home that secures the loan. Funds used for tuition, debt consolidation, or other purposes generally are not deductible. The total acquisition debt across your first and second mortgages also has a cap. Verify your specific situation with a tax professional.
Why is the payoff quote higher than my statement balance?
The statement balance reflects what you owed as of the last billing cycle. A payoff quote adds interest accrued since the last statement (per-diem to the chosen payoff date), any servicer fees, and any prepayment fee the note allows. If you're sending a final payment, ask the servicer for a written payoff quote good through a specific date.
When this calculator helps — and what to do next
The calculator above is built for one product: a fixed-rate home equity loan. Six common homeowner situations and the natural next step in each.
| Situation | Calculator is useful for | Watch before deciding | Next step |
|---|---|---|---|
| You have a fixed home equity loan and are keeping the rate | Showing the payoff date, total interest, and what extra principal would save on your existing schedule | Confirm the loan is fixed-rate (not a HELOC) and use the required payment from your latest statement | Compare total interest with and without extra principal in the calculator above |
| You're already paying — or thinking of paying — extra each month | Estimating how many months you'd shave off and how much interest you'd save | How your servicer applies extras. Some apply extras to the next scheduled payment rather than to principal — ask for them to be applied to principal. See how principal-only payments actually work. | Set up the extra-payment instruction in writing with your servicer before sending the first one |
| You're considering a refinance into another home equity loan | Running the proposed new loan as a second scenario and comparing the total-interest lines side by side | Closing costs and term length. A lower rate on a longer term can still raise total interest | Run the proposed loan in the refinance calculator with the new rate, new term, and closing costs added to the new principal |
| You're thinking about rolling the balance into a new first mortgage | Seeing what your existing home equity loan costs in total interest before you replace it | A new 30-year first mortgage extends the payoff window. Total interest can rise even at a lower headline rate | Compare total interest over your realistic time in the home using the mortgage payoff calculator |
| You used the home equity loan for debt consolidation | Modeling the home equity loan's standalone payoff | Interest deduction generally does not apply when funds were not used to improve the home (IRS Publication 936), and you've moved unsecured debt onto the home as collateral | Compare total interest against your prior debts in the debt payoff strategy calculator |
| You're comparing a home equity loan against a HELOC | Modeling the fixed-loan scenario for an apples-to-apples comparison | HELOCs have draw and repayment phases that this calculator doesn't model | Run the variable-rate scenario in the HELOC payoff calculator |
Where home-equity borrowers get surprised
Most of the surprises on a fixed home equity loan aren't about the amortization schedule itself — that part is straightforward. They're about the framing around the loan: how it differs from a HELOC, what refinancing actually costs, and how the funds were used.
- A home equity loan is not a HELOC. Predictable payment, fixed term, no draw period — the math here only covers the fixed-loan version.
- A predictable monthly payment doesn't mean a cheap payoff. Total interest over a 10- or 15-year term can still be a meaningful share of the loan.
- Closing costs can erase the rate savings on a refinance, especially on smaller balances. Compare total cost including closing costs, not just the new payment.
- Rolling the balance into a new 30-year first mortgage usually lowers the monthly payment and can raise total interest. The headline payment is not the full cost.
- Tax deductibility depends on how the funds were used (IRS Publication 936). The general 'home-equity interest is deductible' framing is more limited than many homeowners assume — verify with a tax professional.
- The loan is secured by the home. Lenders treat it as a second-position loan behind the primary mortgage; for planning the payoff, that mostly shows up in the rate, not in the schedule.
- Prepayment terms vary by lender. Read the note before sending a large lump sum.
- The payoff quote you'll get from the servicer can differ from the statement balance because of accrued interest, per-diem to the payoff date, and any small servicer fee.
Check before you prepay or refinance
A one-page decision memo. Pull each item, write the answer next to it, and run the comparison in the calculator before committing to a large lump sum or signing a new loan.
Current rate and remaining term
Pull both from your most recent statement. These set the baseline the calculator works from.
Payoff quote
Request a written payoff quote from your servicer. It usually differs from the statement balance because of accrued interest and per-diem.
Refinance rate and closing costs
Closing costs are often quoted in the 2–5% range. They are paid up front or rolled in — either way they change the math.
Term reset if you roll into a first mortgage
A new 30-year first mortgage extends the payoff window. Compare total interest over your realistic time-in-home, not just the headline rate.
What the loan funds were used for
Interest deductibility under IRS Publication 936 depends on use of proceeds. Verify your specific situation with a tax professional.
Prepayment fee, if any
Read the note. Most lenders don't charge one, but practices vary by lender and by state.
For the refinance-vs-prepay call specifically, the refinance vs prepay guide walks through how to compare total interest after closing costs, which is the number that actually decides it. This is a planning page, not legal, tax, or financial advice — verify specifics against your loan documents and, where it matters, with a licensed professional.
Where this calculator falls short
The math is exact for fixed-rate amortizing loans with monthly payments, but it doesn't capture every situation. Cases where the output above will mislead you:
- Closing costs are not modeled in the monthly payment shown. Real home equity loans often charge origination, appraisal, title, and recording fees at the start; those change the true cost of the loan but don't appear in the schedule.
- Tax deductibility is not factored. Where deductibility applies under IRS Publication 936, your effective rate after deduction is lower than the headline APR; the calculator uses the headline figure only.
- Refinance scenarios require a separate run. Enter the proposed refinance terms (new principal including any rolled-in closing costs, new rate, new term) as a second scenario and compare the total-interest lines side by side.
- The model assumes a fixed rate and fixed payment, which matches a standard home equity loan. If your loan is actually a HELOC (variable rate, draw period), use the HELOC payoff calculator — the math is meaningfully different.
- Prepayment fees are not modeled. Read the note before sending a large lump sum or paying the balance off early.
