TD Home Equity Line of Credit Calculator

This calculator estimates the monthly payment and total interest for a fully drawn, fixed-rate home equity line of credit (HELOC), using the amount borrowed, APR, and repayment term you enter. It does not calculate TD’s current offer or approval terms; use your lender’s disclosures for those figures.

Formula

The calculator treats the borrowed amount as a fully drawn, amortizing loan with equal monthly payments and a fixed APR throughout the repayment term. It first calculates the payment, rounded to cents, then subtracts the original amount from all scheduled payments to estimate total interest.

• p is the amount borrowed, in dollars.
• apr is the annual percentage rate entered as a percentage, such as 8 for 8% per year.
• r is the monthly interest rate, calculated as apr ÷ 1,200.
• n is the number of monthly payments, calculated as years × 12.
• pmt is the monthly payment in dollars: round[p × r ÷ (1 − (1 + r)⁻ⁿ), 2].
• int is estimated total interest in dollars: pmt × n − p.

The formula assumes that the full amount is borrowed at the start and repaid through equal monthly payments. An actual HELOC may have a borrowing period, variable rates, interest-only payments, fees, or other terms that this calculation does not model.

Worked Example

Using the calculator’s default inputs—$20,000 borrowed, 8% APR, and a five-year repayment term:

1. Convert the APR to a monthly rate: 8 ÷ 1,200 = 0.0066667, or about 0.66667% per month.
2. Find the number of payments: 5 × 12 = 60 months.
3. Apply the payment formula: $20,000 × 0.0066667 ÷ [1 − (1 + 0.0066667)⁻⁶⁰] = approximately $405.53 per month after rounding to cents.
4. Calculate total interest using the rounded payment: $405.53 × 60 − $20,000 = $4,331.80.

With these inputs, the estimated monthly payment is $405.53 and estimated total interest is $4,331.80. The final payment on a real loan may differ slightly because of payment dates, daily interest calculations, rounding, or lender-specific terms.

Assumptions

• The APR is fixed for the full repayment term.
• Payments are equal, made monthly, and begin after one month.
• Interest compounds monthly at APR ÷ 12.
• The calculation excludes lender fees, taxes, insurance, property-related costs, and any optional charges; none are entered here.
• The full amount is borrowed immediately; there are no additional draws, repayments during a draw period, or interest-only payments.

How a TD HELOC Works

TD offers home equity borrowing products, but the precise product, availability, and terms depend on the application and the lender’s current disclosures. A HELOC is generally a revolving credit line secured by a home: a borrower may access funds up to an approved limit during a specified draw period, then repay the balance under the agreement’s terms. Because the home secures the debt, failing to meet the agreement’s repayment obligations can put the property at risk.

A HELOC differs from a standard installment loan. With an installment loan, the borrower receives a set amount and makes scheduled payments. With a line of credit, the balance can change as money is drawn and repaid. The payment calculator above instead models a single amount drawn once and repaid evenly. It is useful for understanding that simplified repayment scenario, not for determining the actual payment on every HELOC phase.

Before relying on a TD-specific estimate, check the current product documents or contact TD directly for the rate structure, draw and repayment periods, fees, payment rules, and eligibility requirements. These details can change and are not inputs in this calculator.

Reading the Estimate and Its Limits

The monthly payment is an arithmetic estimate of principal and interest under the stated assumptions. Total interest is the sum of those rounded monthly payments minus the original amount borrowed. It does not include amounts that may be charged separately or changes that could occur under a variable-rate agreement.

For example, a $20,000 balance on a HELOC may not behave like a five-year fixed-rate loan if the line allows additional draws, has a variable APR, or uses different payment rules during a draw period. The calculator cannot determine what a lender will approve, the credit limit a homeowner might receive, or the amount available from a property. Those require lender-specific information and assessment.

Use the APR and term from an actual disclosure if you want an estimate based on a particular offer. Confirm whether the quoted rate can change and whether the displayed payment includes principal, interest, or other charges. A monthly payment that covers interest alone does not necessarily reduce the balance.

Costs, Risks, and Common Misconceptions

Do not assume that a HELOC’s initial payment, advertised rate, or calculator estimate represents the cost over the entire borrowing period. A variable rate can change the amount of interest due, while fees and payment provisions can affect the overall cost. Review the contract for the details that apply to the specific line.

• Rate changes: Ask whether the rate is variable, how it is determined, and how changes affect payment amounts.
• Draws and repayment: Check when new borrowing ends and how required payments are calculated in each phase.
• Fees: Identify any application, appraisal, maintenance, transaction, or closing charges in the lender’s disclosures.
• Collateral: Remember that the credit line is secured by the home, so missed payments can have serious consequences.
• Balance reduction: Verify whether required payments reduce principal. Interest-only payments leave the amount borrowed outstanding.

A common misconception is that a HELOC’s credit limit is the same as cash already borrowed. It is a maximum available line, subject to the agreement and any conditions; interest is generally tied to amounts drawn, but the contract governs charges and repayment. This calculator takes the borrowed amount as an input and does not estimate a limit.

Alternatives and Comparisons

A home equity loan is commonly structured as a lump-sum installment loan, while a HELOC provides access to a revolving line. A cash-out refinance changes the mortgage borrowing arrangement rather than adding a separate revolving line. Personal loans and other unsecured borrowing do not use the home as collateral, but their pricing and terms are lender-specific. These products have different structures, so compare the disclosed payment rules, total charges, rate behavior, and risks rather than comparing a single monthly-payment figure.

For any option, the relevant figures are those in its current written offer. This page does not recommend a product or assess whether borrowing is suitable for an individual situation.

Frequently Asked Questions

Does TD offer a home equity line of credit?
TD’s available home equity products and terms can vary by location and over time. Check TD’s current official materials or contact the lender to confirm whether a HELOC is available to you and what terms apply.

How do I estimate a TD HELOC payment?
Enter the amount borrowed, APR, and repayment term in the calculator. The result assumes a fixed rate and equal monthly principal-and-interest payments; it may not match a HELOC with variable rates or different draw-period rules.

Is a HELOC payment calculator exact?
No. This calculator uses simplified assumptions and excludes lender-specific fees and changing rates. The payment schedule and disclosure from the lender provide the applicable figures for a particular credit line.

Is a HELOC the same as a home equity loan?
No. A HELOC generally provides revolving access to credit, while a home equity loan is generally a lump sum repaid in installments. The agreements determine the actual borrowing and repayment terms.

Can a HELOC put my home at risk?
Yes. A HELOC is secured by the home. Failure to meet the agreement’s obligations can put the property at risk, so review the contract and contact the lender if payment difficulty arises.

This result is an estimate, and the lender’s disclosure gives the exact figures.
