Each GuideStead calculator works on its own, and they all follow the same three steps.
Start with the pay, work, and household details that apply to your situation.
Treat the result as a practical starting point, and check the assumptions listed on that calculator before any important decision.
Use Copy summary to paste your results into notes or an email, or Print / Save PDF to save a copy.
Each calculator saves your entries in this browser on this device, separately from the others, so it can remember them next time. To remove them, use Start fresh in a calculator or clear your browser data.
No. The numbers you type into the calculators never leave your browser — they aren’t sent to us, to analytics, or to any ad service.
No. There is no login, password, or online finance profile.
They’re honest starting points, not exact figures. Real-world results depend on details a simple estimate can’t know — things like W-4 elections, local taxes, employer-specific deductions and benefits, credits, and rounding. Every calculator lists the assumptions it makes, so the most useful habit is to read those before relying on a number for a real decision.
From primary sources only — the IRS, the Social Security Administration, the Bureau of Labor Statistics, and state revenue departments — never second-hand summaries. Each figure, and the year it applies to, is documented on our Sources page. Where something is a common guideline rather than a hard rule — like the 28%/36% housing ratio — the calculator says so, so you can treat it as a gut check rather than a pass/fail test.
By design. Each tool is scoped to what it can estimate honestly from the numbers you enter. It won’t project decades ahead on an assumed rate of return that nobody can actually know, and it won’t fold in things it can’t measure — career outcomes, program quality, personal fit. A confident-looking number built on a guess is more misleading than helpful, so each calculator notes what it covers and what it deliberately leaves out.
Right on the calculator itself. Each one defines its terms and lists its assumptions on the page where you use them, so anything unfamiliar — like “commute time value,” which is optional context rather than money actually spent — is explained in place. The Sources page carries the underlying references if you want to go deeper.
