The HELOC Calculator computes payments and total costs for a Home Equity Line of Credit. A HELOC is a revolving credit line secured by your home equity, offering a flexible way to borrow money at rates typically lower than credit cards or personal loans.
A HELOC has two phases: the draw period (typically 5-10 years) when you can borrow and repay funds, and the repayment period (typically 10-20 years) when you can no longer draw and must pay back the balance. During the draw period, most HELOCs require only interest-only payments, keeping costs low. During repayment, you pay both principal and interest.
HELOCs typically have variable interest rates tied to the prime rate. As of 2024, HELOC rates generally range from 7.5-10%, depending on your credit score, LTV ratio, and market conditions. Some lenders offer introductory fixed rates or the option to lock a portion of the balance at a fixed rate.
The payment shock between the draw and repayment phases can be substantial. If you drew $50,000 at 8.5%, your interest-only payment is about $354/month during the draw period. When repayment begins, the fully amortized payment jumps to approximately $434/month — a 23% increase. Planning for this transition is essential.
Common uses for HELOCs include home renovations (which may increase home value), debt consolidation, education expenses, and emergency reserves. Because your home secures the loan, defaulting on a HELOC can result in foreclosure. Use this tool wisely and only borrow what you can comfortably repay.
Draw Period Payment (interest-only) = Amount Drawn × Annual Rate ÷ 12
Repayment Period Payment (fully amortized) = P × [r(1+r)n] / [(1+r)n − 1]
Where P = balance at end of draw period, r = monthly rate, n = repayment period in months.
Total Interest = Draw Period Interest + Repayment Period Interest
Total Cost = Principal + Total Interest
The interest-only payment during the draw period is your minimum payment. The full payment shows what you will owe once repayment begins. The available credit shows how much more you can draw. Plan for the payment increase when transitioning from draw to repayment — this is where many HELOC borrowers face financial stress.

A Home Equity Line of Credit is a revolving credit line secured by your home. You can borrow, repay, and re-borrow during the draw period (typically 10 years), then pay it off during the repayment period (10-20 years).
A HELOC is revolving credit with variable rates (like a credit card secured by your home). A home equity loan is a fixed-rate lump sum. HELOCs offer flexibility; equity loans offer payment certainty.
Most HELOCs have variable rates tied to the prime rate. Some lenders offer hybrid options where you can lock portions of your balance at a fixed rate. Variable rates mean payments can increase over time.
The draw period (typically 5-10 years) is when you can borrow and repay funds on your HELOC. Most lenders require only interest-only payments during this phase.
Your HELOC converts to the repayment period. You can no longer draw funds, and payments increase to include both principal and interest. This payment increase can be 20-50% or more.
Yes. Any principal payments during the draw period free up credit for future draws and reduce your balance, lowering interest costs. Early repayment is one of the smartest HELOC strategies.
Variable rates can increase your payment, payment shock at repayment transition, and your home is collateral — defaulting can lead to foreclosure. Also, declining home values can reduce your available credit.
HELOC interest is tax deductible only if the funds are used for home improvements that substantially improve the property. Interest on HELOC funds used for other purposes (debt consolidation, education) is not deductible.
Yes. Lenders can freeze or reduce your HELOC if your home value declines, your creditworthiness changes, or if economic conditions deteriorate. This happened widely during the 2008 financial crisis.
Most lenders allow a Combined LTV (CLTV) of 80-85%. HELOC limit = Home Value × 80% − Mortgage Balance. Some lenders go up to 90% CLTV for excellent credit.
