Credit Card Calculator

Embeddable payoff calculator that models multiple cards and shows when you’ll be debt-free.

Overview:

A quick exploration of a responsive widget for comparing payoff dates and total interest across one or many cards. Inline edits update instantly, and a stacked yearly chart keeps the big picture clear.
