A Home Equity Line of Credit (HELOC) offers flexible access to your home's equity, but the two-phase payment structure can surprise borrowers. Our HELOC calculator shows exactly what you'll pay during the interest-only draw period and the higher principal + interest repayment period. Plan ahead and avoid payment shock.
A HELOC is a revolving line of credit secured by your home equity. Unlike a home equity loan (lump sum), you draw funds as needed during the draw period (typically 5-10 years), paying only interest. After the draw period ends, you enter the repayment period (10-20 years) where you pay both principal and interest—often double the monthly payment.
HELOC Payment Formulas
Draw: Balance × (Rate/12) | Repay: P × r(1+r)^n / ((1+r)^n-1)HELOC payments can double or triple when you transition from draw to repayment period. Know both payment amounts before you borrow to ensure you can afford the higher payment.
Interest-only payments during the draw period mean all that interest adds to your total cost. See the full picture: draw period interest + repayment period interest = total interest paid.
Lenders typically limit combined loan-to-value (CLTV) to 80-85%. Our calculator instantly shows your available equity and whether your desired HELOC amount is within reach.
Fund kitchen remodels, bathroom upgrades, or additions. Draw funds as the project progresses rather than borrowing a lump sum upfront. Improvements may also increase your home's value.
Replace 20%+ credit card rates with 8-9% HELOC rates. The interest savings can be substantial, but remember: you're converting unsecured debt to secured debt backed by your home.
Establish a HELOC as a financial safety net. You pay nothing unless you use it, but have instant access to funds for unexpected medical bills, job loss, or major repairs.
Draw funds each semester as tuition is due. HELOC rates are often lower than private student loans, and interest may be tax-deductible if used for home improvements.
Use your primary home's equity to fund the down payment on a rental property. This strategy can accelerate wealth building but increases your overall risk exposure.
Access funds for small business expenses. Flexible draws match irregular business cash needs. However, be cautious: business failure puts your home at risk.
During the draw period at 8.5% interest, you'd pay about $354/month (interest-only). When you enter the 20-year repayment period, the payment jumps to approximately $434/month (principal + interest). Total interest paid over 30 years: roughly $63,000. Use our calculator to see exact figures for your rate and terms.
