This home equity loan payment calculator estimates your monthly payment and shows how your balance can drop over time for a fixed-rate home equity loan. It works with a term of 10 years or other options such as 5, 15, 20, or 30 years, or selecting Custom to enter a different term length. Add your loan amount and APR, then include an extra monthly payment if you plan to pay more than the standard amount. You can also set a start date and first payment date so the payoff timing lines up with your expected schedule, and the results include charts plus a full amortization table with interest, principal, and remaining balance for each payment.

How to Calculate Home Equity Loan Payment
Enter the loan amount –
Start by entering the amount you plan to borrow through the home equity loan. This is the principal balance the schedule begins with, and it drives every payment breakdown line, including how much goes to interest versus principal over time.
- Use the borrowed amount – Enter the loan principal you expect to owe, not your home value or your available equity limit
- Match your paperwork – If you have a lender quote or disclosure, copy the amount shown there so your estimate lines up
- Include funded amount, not “requested” – If your lender deducts fees from the disbursement, use the amount that becomes your balance
- Check commas and decimals – “50000” and “50,000” are fine, but avoid mistakes like “500,000” when you meant “50,000”
Enter the APR –
Type the APR for your fixed-rate home equity loan. The calculator converts the APR into a monthly rate and uses it to compute both the base monthly payment for your chosen term and the monthly interest portion shown in the schedule.
- Use the fixed APR you were quoted – Enter the rate that stays constant across the loan term
- Enter it as a percent – For example, type 9.25 for 9.25%
- Use your note rate if APR is confusing – If your documents show both, the interest rate on the loan is typically the best match for payment estimates
- Keep it realistic – Very high rates can produce a scenario where a payment may not cover interest if the term and extra payment combination is unusual
Select the start date –
Choose the start date using the date picker. This date represents when the loan is assumed to begin accruing interest and is used to anchor the schedule timing.
- Use your expected funding date – This is usually the day your lender disburses funds
- Keep it consistent with your paperwork – If your disclosure shows a disbursement date, use that date here
- Don’t guess wildly – A start date far from your real timing can change the first period interest estimate
- Make sure it comes before the first payment date – The calculator requires the first payment date to be after the start date
Select the first payment date –
Pick the date you expect to make your first payment. The calculator builds the monthly schedule from this date forward, then adjusts the first period interest if your first payment is not exactly one month after the start date.
- Use the due date shown by the lender – Many loans have a payment due date that does not fall exactly one month after funding
- Expect a different first interest amount in some cases – If the first payment date is earlier or later than a full month after the start date, the first interest is handled differently
- Use the same day-of-month you plan to follow – If your loan bills on the 1st or 15th, use that pattern so the schedule dates look realistic
- Avoid selecting the same day as start date – A first payment date that is not after the start date will trigger an error
Enter an extra monthly payment if you plan to pay more than the required amount –
Use this field if you intend to pay additional principal every month. The calculator adds this value on top of the base payment for the selected term and then recalculates the schedule to show how much earlier you finish and how total interest changes.
- Enter a monthly extra amount – This assumes the same extra payment is added each month
- Use it for payoff planning – Even small extra payments can shift the payoff date and total interest noticeably over time
- Set it to 0 for the standard schedule – Leaving it blank or entering zero keeps the calculation at the base payment only
- Use realistic amounts – If you enter a large extra, the schedule may end early, and the final payment will adjust to bring the balance to $0.00
Choose the loan term, including 10 years and the other term options –
Select how long you want the loan to run. The term controls the number of scheduled monthly payments used in the payment formula and determines the baseline payoff timing before extra payments shorten it.
- 10 years – Use this when you want a shorter repayment window and you are comfortable with a higher payment compared with longer terms
- 5 years – Typically produces the highest payment, but often the lowest total interest because the balance is paid down quickly
- 15, 20, and 30 years – Generally lower the monthly payment compared with 10 years, but increase total interest because the balance lasts longer
- Custom – Select Custom when you need a different term length, then enter years in the box that appears
- Use decimals if needed – The Custom field accepts values like 3.5 years if you want a non-standard term
- Watch the term note – The “Selected term is … years” line confirms what the calculator is using for the schedule
Review the planned monthly payment preview –
Before running the schedule, check the “Planned monthly payment” line. It reflects the payment amount based on your loan amount, APR, term, and any extra payment you entered, giving you a quick way to compare scenarios.
- Use it as a quick reality check – If the number looks far off, re-check loan amount, APR, and term first
- Remember it includes extra payment – If you entered an extra monthly payment, the preview reflects the combined planned payment
- Compare term options quickly – Changing the term is a fast way to see how payment size shifts before reviewing the full schedule
- Treat it as an estimate – Exact lender payments can vary due to rounding rules, escrow, or fee handling
Select a day count basis if the calculator shows it –
This option only appears when your first payment date is not exactly one month after the start date. In that situation, the first period is treated as a partial period, and the calculator uses a day-based method to estimate interest for that first span.
- Why it appears – It shows up when the first period is not a full month, so the first interest is based on days
- Actual/365 – Uses the actual number of days between the two dates with a 365-day year
- 30/360 – Uses a 360-day year convention that some lenders apply for certain products
- This impacts the first period only – After the first payment, the remaining schedule follows standard monthly calculations
- Use your lender’s convention if known – If your documents reference a day count method, pick the matching option
Click Calculate to generate the full results –
After your inputs are set, click Calculate to generate the results. The calculator will display a summary, charts, and the amortization schedule based on the values you entered.
- Monthly payment – Shows the planned payment amount the schedule is built around
- Total interest – Adds up all interest across the schedule until payoff
- Payoff date – Shows the scheduled payoff timing based on your inputs and any extra payments
- Read the summary text – It explains the estimate in plain language, including how the first period was handled when dates don’t line up
Use the charts to understand payoff progress and payment makeup –
Use the charts at the top of results to see how the balance falls over time and how interest versus principal changes as you progress through the loan.
- Balance over time – Shows how quickly the remaining balance declines based on your payment level
- Interest and principal by payment – Shows how early payments typically include more interest and later payments shift toward principal
- Use it for comparing scenarios – Run Calculate again with a different term or extra payment to see how the charts change
- Expect sampling on long terms – For longer schedules, the chart uses a sampled set of points so it stays readable
Open the amortization schedule for the full breakdown –
Expand the “View amortization schedule” section to see each payment with its date, total payment amount, interest portion, principal portion, and remaining balance.
- Payment date column – Shows each monthly payment date starting from your selected first payment date
- Interest and principal columns – Shows how each payment is split based on the remaining balance at that time
- Balance column – Shows the remaining balance after each payment is applied
- Final payment can differ slightly – The last payment may be adjusted to bring the balance to $0.00 due to rounding
Export or share your results when you need to save them –
Once you have a scenario you want to keep, use Export or Share so you can store the estimate, send it to someone, or compare it later.
- Export CSV – Good for quick review or importing into other tools
- Export Excel – Useful if you want to sort, add notes, or run additional calculations
- Export PDF – Useful for sharing a clean summary and schedule in a fixed format
- Share – Creates a link that keeps your entered inputs, which is useful for sending the same scenario to someone else
Tips
- Change one input at a time when comparing options. Keep everything else the same so the difference you see has a single cause.
- Match your real timing using the two dates. Set Start date to when funds are received and First payment date to the lender’s first due date so the payoff date and first schedule line match your plan.
- Check the first row if dates are not exactly one month apart. That first period can be prorated, so the first interest amount may look different than later months.
- Use Extra monthly payment for “what if” testing. Try small numbers first, like $25, $50, or $100, to see how payoff timing and total interest change before you commit to a larger extra.
- Use Custom term for non-standard loans. If your lender uses something like 7, 12, or 18 years, Custom gives you a closer match than selecting a nearby preset.
- If the calculator shows “payment does not cover interest,” adjust the inputs. Reduce APR, increase the term, or remove extra if it causes odd results, then recalculate.
- Export each scenario you plan to compare. Save one file per run (for example, “10 years,” “15 years,” “10 years + $100 extra”) so you can compare totals without rerunning everything.
Important
- This calculator assumes a fixed interest rate for the entire term. If your loan has a variable or adjustable rate, the real payments and payoff timing can change over time.
- The first payment can differ from later payments when dates do not align. If the first payment date is not exactly one month after the start date, the first interest amount is prorated and may appear higher or lower than expected.
- Extra monthly payments change the payoff timing. Adding extra reduces the balance faster, which can shorten the loan term and affect the final payment amount.
- Very short custom terms may create unrealistic payments. A short term combined with a high APR can lead to payments that are difficult to maintain or fail to cover interest.
- Rounding can slightly adjust the final payment. Monthly amounts are rounded to cents, so the last payment may be a little higher or lower to bring the balance to zero.
- Day count selection affects only the first period. Choosing Actual/365 or 30/360 changes interest calculation only when the first period is partial, not the entire schedule.
- Results are estimates, not lender quotes. Lenders may use different rounding rules, fee handling, or payment timing that cause small differences from this schedule.
- Always confirm with your lender before committing. Use the output for planning and comparison, then verify the exact payment details with official loan documents.
FAQs
It estimates the monthly payment for a fixed-rate home equity loan and generates an amortization schedule that shows how each payment is split between interest and principal until the balance reaches $0.
Yes. Select 10 years in the Term dropdown to run it as a 10 years home equity loan payment calculator, then compare it with 5, 15, 20, 30, or Custom terms to see how payment and total interest change.
Loan amount is the amount you borrow. Extra monthly payment is an additional amount you choose to pay every month on top of the planned payment, which reduces the balance faster and can shorten the payoff time.
No. Extra payments affect how quickly the balance goes down, but the APR you enter stays the same throughout the schedule since it is a fixed-rate estimate.
They let the schedule follow real timing. The start date represents when funds are disbursed and interest begins. The first payment date sets when your first payment is due, which determines the timing for the entire schedule.
It appears only when the first payment date is not exactly one month after the start date. In that case, the calculator prorates the first period’s interest by days, and the day count basis controls how that daily interest is computed.
Actual/365 uses the actual number of days divided by 365.
30/360 assumes 30 days per month and a 360-day year.
This selection matters only for the first partial period in this calculator.
If the first period covers more than a typical month due to your chosen dates, the prorated first interest can be higher. If the first period is shorter, it can be lower. After that, the schedule uses standard monthly interest.
It is the monthly payment amount used for the schedule based on your loan amount, APR, term selection, and any extra monthly payment you entered. It is a planning number for the schedule the calculator generates.
It is the date of the final payment shown in the amortization schedule. If you add extra monthly payments, the payoff date can move earlier than the selected term end.
Differences can happen due to lender-specific rounding rules, the exact interest accrual method, payment processing timing, and how they handle the first period. This calculator gives a solid estimate for planning and comparison.
It shows how the remaining loan balance declines across payments. It is a quick way to see how fast you reach payoff under the selected term and extra payment amount.
It shows the mix of interest and principal across payments. Early payments typically have more interest and less principal, then the balance shifts as the loan is paid down.
No. A HELOC often includes a draw period, changing balances, and commonly a variable interest rate. This calculator is for a fixed-rate home equity loan with a fixed term and a monthly payment schedule. If you are estimating payments for a line of credit, use this HELOC payment calculator instead.
