About Fynliko

Fynliko builds free, no-signup calculators for the everyday money decisions that cost people the most: paying off debt, clearing a credit card, and taking out a loan. Every tool runs entirely in your browser — we never ask you to register and we store none of the numbers you enter.

Who writes Fynliko

Colson — Founder & consumer-finance researcher, ColsonSuperApps LLC.

Colson is the founder of ColsonSuperApps LLC and the researcher behind Fynliko's calculators. He builds the math engine from first principles — standard amortization, the debt-snowball/avalanche method, and credit-card minimum-payment rules — and pins every average-rate figure to authoritative sources such as the Federal Reserve (G.19), the CFPB and FDIC. He is a software engineer, not a lender or licensed financial advisor; Fynliko provides estimates and education, never advice, credit or a loan.

How we keep the numbers accurate

Every calculator is built on standard, published financial math — amortization, the snowball/avalanche method, credit-card minimum-payment rules. The math engine is covered by an automated test suite that checks each formula against known-good reference values before any release, so a code change can't silently break a result. Average-rate figures are pinned to authoritative primary sources (the Federal Reserve's G.19 series and industry data), each shown with its as-of date and refreshed on a schedule. See our methodology for the detail.

How we make money

Fynliko is free and supported by advertising and affiliate partnerships. When you apply for a card or request a loan or consolidation quote through a partner link, we may earn a commission — at no cost to you, and with no effect on your rate or terms. We only point to legitimate cards, personal loans and reputable debt consolidation, never payday lenders or debt-settlement schemes.

A clear disclaimer

ColsonSuperApps LLC is not a lender, bank or licensed financial advisor. Our calculators provide educational estimates using standard financial math and published average rates. Your actual rate, payment and terms depend on your credit and lender — always confirm with them before you act.
