Use each calculator on its own or move between GuideStead calculators for a connected comparison.
Start with the pay, work, and household details that apply to your situation.
Each calculator states which inputs are saved automatically in this browser. Matching saved inputs are filled into other GuideStead calculators when the same information is used.
Use each calculator result as a practical starting point, then review the assumptions listed for that calculator before making an important decision.
Gross pay, pay frequency, filing status, state tax rate, 401(k) percentage, annual health premium, job-comparison entries, raise-comparison entries, car-purchase entries, college-offer entries, first-home entries, employer-match entries, and commute-cost entries are saved automatically in this browser on this device. Use Start fresh in a calculator, or clear your browser data, to remove the saved inputs.
No. The calculations run in your browser, and the financial numbers you enter are not uploaded by the calculators.
No. There is no login, password, or online finance profile.
Your payroll system may include W-4 details, local taxes, employer-specific deductions, benefit rules, credits, rounding, and other items not included in the paycheck estimate.
The paycheck calculator uses tax-year 2026 assumptions.
The raise calculator uses Consumer Price Index for All Urban Consumers (CPI-U) annual averages through the latest completed year available in the calculator.
Instead of a state dropdown, the paycheck and job-offer calculators ask for your effective state income tax rate directly, as a percentage. Enter the rate you know applies to you, or leave the field blank to leave state tax out of the estimate entirely. This keeps the calculators accurate for every state, including ones with unusual rules (mandatory local taxes, phase-out deductions, multi-bracket credits) that a simplified model could easily get wrong.
Not directly. The National Highway Traffic Safety Administration (part of the U.S. Dept. of Transportation) tracks crash-test safety ratings and recalls, but not reliability — that's private-sector data (Consumer Reports, J.D. Power, and similar), not something a government agency tracks. Rather than building in a dataset covering thousands of makes, models, and years — which would go stale fast — the car purchase calculator links directly to NHTSA's own ratings and recall lookup tools, which are free, official, and always current.
No, deliberately. It compares financial cost only — sticker price, grants and scholarships, loans, and the resulting monthly payment after graduation. Program quality, career outcomes, expected earnings by major or school, and personal fit all matter, but they aren't part of what this tool measures.
Not exactly — it's a widely used guideline, not a law or a single lender's cutoff. Many loans (like FHA) approve higher ratios, especially with good credit or savings. Treat it as a helpful gut check, not a pass/fail test. More detail.
A multi-decade projection depends heavily on an assumed rate of return, which nobody actually knows in advance — showing one number could look like a prediction rather than an estimate. This calculator sticks to a this-year snapshot: are you capturing your full match, and what's your savings rate right now.
It's optional context, not real money spent. It applies your own gross hourly pay to the hours you spend commuting, so you can see the time trade-off next to the dollar cost. Job Offer Comparison uses the same idea. Turn it off if you'd rather see dollar costs only.
No. GuideStead calculators are for estimates and planning only.
