HELOC Calculator – Estimate Home Equity Line Payments
Estimate payments on a home equity line of credit during draw and repayment.
About the HELOC Calculator
What is the HELOC Calculator?
A HELOC calculator estimates the interest-only payment during a home equity line of credit draw period and the higher payment once repayment begins.
Why use this calculator?
A HELOC lets you borrow against your home equity as needed. Understanding both phases of the payment prevents a shock when the draw period ends.
How to use it
- Enter your total credit line.
- Enter how much you have drawn.
- Enter the variable interest rate and the repayment term.
- Compare the interest-only and full repayment payments.
Formula
Interest-only = drawn × (rate ÷ 12); full payment uses the amortizing formula.
HELOC rates are usually variable and tied to a benchmark, so payments can rise when rates increase.
Frequently Asked Questions
What happens when the draw period ends?
Interest-only payments stop and you must repay principal plus interest, which can sharply raise the monthly amount. Plan for the jump in advance.
Is a HELOC better than a home equity loan?
A HELOC is flexible and good for ongoing or uncertain needs. A fixed home equity loan gives a predictable rate and payment for a lump sum.
What is included in a monthly mortgage payment?
Most payments combine principal, interest, property taxes and homeowners insurance (often called PITI). Some loans also include private mortgage insurance (PMI).
What is PMI and when can I drop it?
Private mortgage insurance is usually required when your down payment is under 20%. You can typically request removal once you reach 20% equity.
Fixed versus adjustable rate — which is better?
A fixed rate keeps the same interest rate for the whole term, giving predictable payments. An adjustable rate starts lower but can rise after the initial period.
How much house can I afford?
A common guideline is that housing costs stay below 28% of gross monthly income and total debt below 36%, though lenders and budgets vary.
What is the difference between pre-qualification and pre-approval?
Pre-qualification is a quick estimate based on self-reported data. Pre-approval is a verified commitment after a lender reviews your finances.
What is a credit utilization ratio?
It is the share of your available credit that you are using. Keep it below 30%, and ideally below 10%, to protect your credit score.
Will paying off a card hurt my score?
No. Paying down balances usually helps your score by lowering utilization. Closing the account, however, can reduce your available credit.
What is the minimum payment trap?
Minimum payments are set low, so most of the payment goes to interest and the balance lingers for years. Paying more than the minimum saves substantial interest.
