HELOC Calculator

Estimate a HELOC draw-period payment, repayment-period payment and combined loan-to-value ratio.

The draw-period payment is interest-only. The repayment estimate amortizes the draw amount over the selected repayment period.

Method

The draw-period estimate is interest-only: draw amount multiplied by monthly rate. The repayment estimate amortizes the draw amount over the repayment period.

Example

A $60,000 HELOC draw at 9.5% has an interest-only payment of about $475 per month during the draw period. If repaid over 15 years at the same rate, the amortized payment is about $626 per month.

Common mistakes

Do not assume the draw-period payment will stay the same after repayment begins. Variable APR changes can also move both estimates.

Limitations

HELOCs often have variable rates, draw limits, annual fees, minimum payments and conversion rules. This is not a credit offer or approval estimate.
