Use the calculator below to estimate the maximum home equity line of credit amount you may be able to borrow, based on the value of your home, your remaining mortgage balance, and the loan-to-value (LTV) ratio acceptable by the lender.
HELOC stands for Home Equity Line of Credit (HELOC). It acts as a revolving line of credit secured by your home. It works similarly to a credit card but is backed by your home equity. You don’t receive a lump sum upfront like traditional loans. In this particular loan, you borrow an amount as needed up to an approved credit limit.
Your own home acts as collateral for which you borrow money. The interest rates for this loan vary greatly and are generally less than those of other personal loans or credit cards.
A HELOC has two distinct phases, summarized below.
During this period, you have much flexibility. For example, you can borrow money, pay it back to the lender, and borrow again. The payments vary depending on the outstanding balance and the rates. In this period, most of the lenders require interest-only payments.
During this period, you can no longer withdraw funds. You have to pay for both interest and the principal. That’s why the payment keeps increasing every month.
| Phase | Duration | Payment Type | Can Withdraw Funds? |
|---|---|---|---|
| Draw Period | 5–10 years | Interest-only (usually) | Yes |
| Repayment Period | 10–20 years | Principal + Interest | No |
Many borrowers are shocked due to this sudden transition. Our free HELOC payment calculator prepares you for that change.
Lenders typically allow borrowing up to 80%–85% of your home’s value, minus your existing mortgage balance.
(HomeValue × LTVLimit) – Mortgage Balance = Maximum Credit Line
In the example below, we have simplified this formula with assumed values.
| Factors | Values |
|---|---|
| Home Value | $500,000 |
| LTV Limit | 80% |
| Mortgage Balance | $210,000 |
| Maximum HELOC | $190,000 |
Calculation:
$500,000 × 80% = $400,000
$400,000 – $210,000 = $190,000
Our HELOC loan calculator automatically computes this for you.
HELOC payments are not fixed like traditional mortgages. Each moving part has a direct effect on how much you will pay each month. It helps you plan smartly and prevent surprises later on.
Below are some costs associated with it.
Most HELOCs have variable interest rates. It means your rate can rise or fall over time.
The rate is usually calculated as
Prime Rate + Lender’s Margin
You only pay the interest on your borrowed amount, not on your credit limit. As your borrowed balance decreases, the interest charges fall accordingly.
The monthly payments are greatly dependent on which period of the loan you are currently in. In the draw period, you only pay interest. In the repayment period, you pay both the principal and the interest.
These are the contextual limits that restrict how high your variable limits can rise. These can be either periodic caps or lifetime caps.
These rate caps protect the borrowers from unlimited increases. However, the payments can still fluctuate in volatile markets.
HELOC is not limited only to interest charges. There are also some other costs that you should consider.
These are the costs that are paid while borrowing the loan and signing the document. These are one-time charges only. Here are some of the worth-mentioning costs.
Some lenders advertise that they don’t charge any closing fees. However, they adjust those prices with higher interest rates, early termination fees, and minimum balance requirements. We recommend comparing at least 3 to 5 lenders and choosing the one that is most affordable for you.
There are also many ongoing costs that you must consider. These charges are paid each month. The amount may fluctuate depending on the loan terms and the principal.
Here are some of those costs.
These pieces are generally very small. However, if they continue to accumulate, they can become a significant cost burden. Especially, it happens in loans with long draw periods.
Our HELOC calculator allows you to adjust all those fees so you can have a precise idea of much you will have to pay each month.
Just like any other loans, HELOCs have certain specific requirements. However, these requirements are much more flexible, as your house is collateral here.
The table below lists all the criteria that you must fulfill in order to stay eligible for the loan.
| Factor | Typical Requirement |
|---|---|
| Credit Score | 620–680+ preferred |
| Debt-to-Income (DTI) | Below 43% (sometimes up to 50%) |
| Loan-to-Value (LTV) | 80–85% combined maximum |
| Income Stability | 2+ years of employment history |
| Property Condition | Must meet lender standards |
The borrowers with a credit score lower than 630 face difficulty or avail of the loan at higher interest rates.
Not every time is the HELOC an ideal loan for you. It has multiple benefits as well as some drawbacks. Be clear about those pros and cons before signing the agreement.
