About DebtHydra
DebtHydra started with a simple frustration: most personal finance websites are trying to sell you something. Credit card offers, loan referrals, paid apps. The free tools are buried under upsells, and the advice is often designed to benefit the advertiser more than you.
This site does one thing: gives you honest, accurate financial calculators and plain-language guides to help you understand your debt and make a real plan to eliminate it. No sign-up. No paywall. No lead-gen forms pretending to be advice.
The calculators use standard financial math, and the guides are written in plain English rather than finance-speak. Everything is designed to be useful even if you never buy anything from anyone.
How the calculators work
All four calculators use standard financial formulas, the same math lenders use:
- Debt snowball & avalanche — Each month, interest is applied to each balance at its monthly rate (APR ÷ 12). Minimum payments are applied first; extra payment goes to the target debt in the chosen order. When a debt reaches zero, its freed-up payment rolls into the next target. This follows the standard amortisation model documented by the Consumer Financial Protection Bureau (CFPB).
- Auto loan — Uses the standard fixed-payment amortisation formula: M = P × [r(1+r)ⁿ] / [(1+r)ⁿ – 1], where P is principal, r is monthly rate, and n is term in months. Output matches lender-issued Truth in Lending disclosures.
- Emergency fund — Compound interest is applied monthly at APY ÷ 12. Contribution is added each month before interest, consistent with how high-yield savings accounts compound per FDIC-insured account terms.
Interest rate benchmarks cited in guides reflect published Federal Reserve G.19 consumer credit data and CFPB consumer credit trend reports. All results are estimates — actual payoff outcomes depend on your lender's exact terms, fees, and payment timing.
Editorial approach
DebtHydra is independently operated as an educational project. The goal is to explain debt payoff tradeoffs clearly, disclose assumptions honestly, and update pages when guidance or site features materially change.
We aim to keep calculators usable without login walls, avoid exaggerated claims, and make it obvious when something is an estimate rather than a guarantee.
How the site is supported
DebtHydra may use clearly labeled advertising to help cover hosting, development, and publishing costs while keeping the calculators free. Ads should never change the math in the tools or the editorial standards of the guides.
We do not sell debt settlement programs, promise guaranteed outcomes, or present paid placement as independent financial advice. If that ever changes, we'll say so plainly.

A note on accuracy
The numbers these tools produce are estimates. Real loan balances, interest calculations, and payoff amounts can differ based on your lender's specific terms, fees, and payment timing. Always verify important financial decisions with your actual lender or a qualified financial professional. See our full disclaimer.
