HELOC Calculator
A HELOC calculator would show how interest on the amount you have drawn can change when the rate or the balance changes. This page does not run that tool. There is no form, and the figure below is a labeled example, not a payment a lender would bill.

What the later calculator would use
The CFPB’s HELOC page says you borrow against a credit limit during a draw period, payments during that period are often based on the current balance, and the rate is usually variable. A useful calculator would take the balance you have drawn and an interest rate you type, and it would say that a minimum payment can be more than the interest. It would not look up a live rate, and it would not know the margin, the index, or the floor in a note you have not entered.
It also would not model the repayment period by itself. The CFPB says payments are often significantly higher after the draw ends, and that some plans require the full balance at the start of repayment. Those terms belong on the plan documents. The comparison of a HELOC with a lump-sum home equity loan is on the HELOC vs home equity loan page.
A labeled month of interest
This is an example, not a loan offer and not a quoted HELOC rate. On a drawn balance of $10,000.00 at 6 percent a year, one month of interest is $50.00. The calculation is the balance times the annual rate, divided by 12. It is not a minimum payment, not a draw-period bill, and not the payment after the draw ends. Estimates only; your lender's numbers win.
The home equity loan calculator page uses a fixed schedule instead of one month of interest on a revolving balance. That calculator is not built yet either. A first-mortgage payment that includes taxes and insurance is the full-payment calculator, which does run in the browser.
What this page will not do
It will not name a lender, show a live rate, or treat the CFPB’s $300 figure as your minimum draw. That $300 is the CFPB’s example of a minimum some plans require, not a rule and not a fee. A freeze on further draws, which the CFPB says can follow a large drop in home value or a change in your finances, is also outside a payment formula.
Because the rate is usually variable, next month’s interest can differ even when the balance does not. A calculator that pretended otherwise would be a fake tool. When a calculator is added, it will still be an estimate from numbers you type. The comparison page explains the three-business-day right to rescind. For a HELOC on your principal dwelling it comes from 12 CFR 1026.15; for a closed-end home equity loan it comes from 12 CFR 1026.23.
Questions people ask
Can I calculate a HELOC payment on this page?
No. The calculator is not built. The only figure on the page is a labeled example of one month of interest on $10,000 at 6 percent, which is $50.00. A real HELOC payment depends on the plan, the balance, and the rate.
Is HELOC interest the whole payment?
Not necessarily. The CFPB says many HELOCs have minimum monthly payments based on the current balance, and that the payment is often much higher in the repayment period. Some plans require the full balance when repayment starts.
