Money Scale
About Money Scale

Make money make sense.

Money Scale is a free personal-finance toolkit: sourced calculators, plain-English lessons, and a Financial IQ game.

What Money Scale is

Money Scale exists for one reason: to take the intimidating parts of personal finance and turn them into a few clear clicks. Drop a salary into the homepage calculator and you'll see exactly where your paycheck goes — federal tax, FICA, state tax, and what's actually left to spend or invest. Open the calculator suite and you'll find nine free tools covering the topics that move the needle: savings vs investing, debt payoff, emergency funds, inflation, retirement, and rent vs buy.

Who it's for

Money Scale is built for the millions of people who never got a real personal-finance class. If you've ever wondered "is my salary good?", "should I pay off debt or invest?", or "how much should my emergency fund actually be?" — Money Scale is for you. The Simple mode is friendly enough for first- time investors; the Advanced mode is detailed enough for people who want to see every assumption.

Why it's free

Money matters too much to be paywalled. Money Scale is free today and will stay free. To keep it that way, we may run lightweight ads in the future (no popups, no autoplay video, no dark patterns) — but ads are not running right now. Either way, there's no pro tier, no affiliate score-stuffing, and no email harvesting. Every calculation runs in your browser; we never see the numbers you type.

Editorial standard

The calculators use cited public-data assumptions — federal tax brackets from the IRS, average savings and CD rates from the FDIC, historical inflation from the BLS, average market returns from public index data. Each assumption is linked to its source on the relevant calculator. Lessons are written in plain English and reviewed against published sources before shipping; every lesson has a Sources section at the bottom.

Money Scale is published as a brand, not under a personal byline — there are no author bios because the calculators and lessons are deliberately source-driven, not opinion-driven. If you spot something out of date or wrong, please email us; corrections ship fast.

Built in 24 hours

Money Scale was designed in under a day and fully built in under a day for Replit's 10th birthday build-a-thon. We did our homework, but if a number ever looks off please let us know. You'll find the full friendly disclaimer in the footer of every page.

Not financial advice

Money Scale is educational. It doesn't know your income, debts, taxes, or goals, so it can't give you personalized advice — and nothing on the site is investment, tax, legal, or accounting advice. Talk to a qualified professional before making any real money decision.

Keep Money Scale free

We keep this site free because we believe financial education should be free — everyone deserves the tools to understand their money and build their financial future without a paywall. Running and maintaining the site does cost real money, though. If Money Scale has helped you and you'd like to chip in, you can support us on Ko-fi. It's entirely optional, with no perks behind it — every coffee just helps keep the calculators running for the next person.
