What it is

A payoff planner for a home-equity line of credit. Model the interest-only draw period, see the payment jump when repayment starts, stress-test rate increases, and find out exactly what an extra monthly payment saves you.

Why we built it

A HELOC is a revolving line, not a mortgage — and every fixed-mortgage calculator gets it wrong. Homeowners approaching the end of their draw period get surprised by a payment jump they could have seen years ahead, and "velocity banking" videos sell them hype instead of math. No focused tool modeled the draw-to-repayment flip honestly, so this one does.

Want one like this?

HELOC Payoff Simulator is one of 92. We can build yours.

Every app on the shelf started as one honest problem, scoped small and built native, end to end. That’s exactly how we approach client work — designed, built and shipped, without the bloat.
