Home Equity Calculator (2026)

Each product converts equity into cash differently, and the right one depends far more on how you will use the money than on which has the lowest headline rate.

A HELOC runs in two phases, and the transition between them catches borrowers out with some regularity.

During the draw period — commonly ten years — you may borrow, repay and re-borrow, and many lenders require only interest payments. Because those payments are small, the balance often does not reduce at all.

At the end of the draw period the line closes and the repayment period begins, typically over ten to twenty years, with payments now covering both principal and interest. The jump can be severe: a $100,000 balance at 8% costs roughly $667 a month in interest alone during the draw, then roughly $1,213 a month on a ten-year repayment schedule.

HELOC rates are usually variable, tied to the prime rate. A line drawn in a low-rate period can become considerably more expensive with no action on your part, which is the principal risk of using one for a long-lived balance.

Interest on home equity debt is deductible only where the funds are used to buy, build or substantially improve the home securing the loan, and only if you itemise. Using the money for debt consolidation, tuition, a car or investing makes the interest non-deductible regardless of the collateral.

Even when the use qualifies, the deduction is only worth something if total itemised deductions exceed the standard deduction — $16,100 single and $32,200 married filing jointly for 2026. Many households that qualify on use still receive no benefit.

Treat any tax advantage as a secondary consideration rather than a reason to borrow. The interest saved is a fraction of the interest paid.

The defensible cases share a feature: the borrowed money either increases the value of the asset securing it, or replaces more expensive debt without recreating it.

Renovations that add value can return part of the outlay at sale, though almost never all of it — cost-versus-value studies consistently show most projects recouping only a portion, with kitchens and bathrooms typically recovering less than exterior and structural work.

Consolidating high-interest debt is arithmetically attractive: replacing 24% credit card debt with 8% secured debt is a large saving. The danger is behavioural. If the cards are used again, the household ends up with both the consolidated loan and fresh card balances, having converted unsecured debt into debt that can take the house.

The weakest cases are consumption — vehicles, holidays, weddings — where a depreciating or vanishing benefit is secured against the family home for a decade or more.

Extra principal payments —

the most reliable method. Each additional dollar reduces the balance permanently and removes that dollar from every future interest calculation.

Biweekly payments —

paying half the monthly amount every two weeks produces 26 half-payments — one extra full payment per year — typically shortening a 30-year loan by four to five years.

Shorter term refinance —

moving from a 30-year to a 15-year loan builds equity far faster, at the cost of a materially higher required payment.

Value-adding improvements —

raises the numerator, though returns vary widely by project and market and are rarely full recovery.

Market appreciation —

contributes but is outside your control and should not be relied on in planning.
