Why MaaX exists
The biggest money decisions — buying a home, paying off debt, saving, investing for retirement — come down to math most people were never taught. The information exists, but it's usually buried in jargon, gated behind sign-up forms, or wrapped around a sales pitch.
MaaX takes a different approach: free calculators that answer real questions instantly, and plain-language guides that explain the decisions behind the numbers. No accounts, no upsells, no noise.
How MaaX works
Every calculator on this site runs entirely in your browser. When you enter a home price or a debt balance, that number is processed on your own device — it is never transmitted, stored, or seen by anyone, regardless of any other tools running on the page. The site has no user accounts and no sign-up forms. We do use Google Analytics to understand overall traffic; see our Privacy Policy for exactly what that does and doesn't include.
What's here today
MaaX currently offers 25 calculators across six categories — home, auto, debt, saving, investing, and income & business — plus six in-depth guides covering the decisions behind the numbers. Everything you see on the site works today; we'd rather ship tools that are genuinely useful than pad out a count with half-finished ones.
Our principles
- Free means free. No premium tiers, no paywalls, no catches.
- Private by design. Your numbers stay on your device, always.
- Plain language. If a sentence needs a finance degree to parse, we rewrite it.
- Honest math. Every calculator states its assumptions and its limits.
A note on advice
MaaX provides education and estimates, not personalized financial advice. Our tools are a starting point for your own decisions — for major moves, it's worth confirming the numbers with your lender, bank, or a qualified advisor. See our disclaimer for details.
