HELOC Calculator
Estimate your HELOC limit, payment, and borrowing cost before using your home equity.
Credit Limit Specs
Draw & Repayment
Draw Period
Interest-only payments based on what you draw plus any fees.
Repayment
Amortized payments (Principal + Interest) to zero the balance.
Payments are estimated based on a drawn amount of $50,000 (Draw + Fees).
Use Equity With Control
A HELOC can give you flexible access to cash, but it is not free money. It is a credit line secured by your home.
A HELOC calculator helps you estimate how much you may be able to borrow, what your payment could look like, and how interest may change during the draw and repayment periods.
Credit Limit
Your limit depends on home value, mortgage balance, credit profile, income, lender rules, and combined loan-to-value ratio.
You may have strong equity, but lenders usually require you to keep part of that equity in the home.
Draw Amount
A HELOC works like a revolving credit line.
You can borrow what you need up to your approved limit. Your payment is usually based on the amount you use, not the full line.
Payment Shift
Many HELOCs have a draw period followed by a repayment period.
During the draw period, payments may be lower. During repayment, you may need to pay principal and interest, which can increase the monthly payment.
Rate Risk
HELOCs often have variable rates.
If rates rise, your payment may rise too. This makes it important to test higher-payment scenarios before using the credit line.
Smart Uses

- Home improvements

The best use has a clear purpose and a realistic repayment plan.

HELOC Planning Note
A HELOC calculator helps you borrow with discipline instead of guessing. By checking your credit limit, draw amount, payment change, and rate risk, you can decide whether using home equity supports your budget or adds pressure.
Quick Answers
How is a HELOC payment calculated?
During the draw period (often 10 years), your payment is usually interest-only based on the amount you have actually drawn, not your full credit limit. During the repayment period (often 15 to 20 years), your payment includes both principal and interest to pay off the balance.
What is a HELOC draw period?
The draw period is the time during which you can actively borrow money from your HELOC, much like using a credit card. It typically lasts 5 to 10 years.
Why did my HELOC payment increase?
Your HELOC payment can increase for two main reasons: 1) Your variable interest rate increased. 2) Your draw period ended, and you entered the repayment period, requiring you to start paying back the principal balance in addition to interest.
How much of my home equity can I get in a HELOC?
Most lenders allow you to borrow up to 80% or 85% of your home's appraised value, minus your current mortgage balance and any other liens.
