Crystal Payoff was built for a simple reason: most debt payoff calculators are buried inside large financial sites that use them as funnels for credit card applications. You arrive with a real problem — too much high-interest debt — and leave with three pre-approved offers and no clearer sense of how to pay anything off.
This tool is different. It starts with the math and shows you the optimal payoff path first. Financial product recommendations, if they appear at all, are secondary and always clearly disclosed. The order is intentional: get the answer, then decide whether any product is worth your attention.
Why the avalanche method
The debt avalanche pays the minimum on every card and directs every extra dollar at the highest-interest balance. It is the mathematically optimal payoff order — no alternative arrangement saves more in interest. We surface it by default because it's the most honest starting point.
Who built this
Crystal Payoff was built by someone with a background in financial technology and compliance. The calculator is grounded in standard amortization math — the same logic your card issuer uses to compute your monthly interest charge — and the editorial content is written with consumer-protection guidelines in mind.
What it costs
The calculator is free and requires no account. You don't enter your email, your name, or anything that could be used to contact you. You enter card balances and rates, and you get a plan.
Crystal Payoff does participate in affiliate programs with financial institutions — see the affiliate disclosure for the full picture — but those relationships do not influence the calculator output or the recommended payoff order.
