Frequently asked questions
Which calculator should I start with?
Depends on the decision. Buying a home: Mortgage + Home Affordability + Rent vs Buy. Paying down debt: Debt Snowball or Avalanche. Investing: Compound Interest. Planning retirement: 401(k) and Roth IRA. The clusters above route by intent so you don't have to guess.
How current are tax brackets and contribution limits?
Federal tax brackets, 401(k)/IRA/HSA limits, FICA wage base, and Medicare premiums are refreshed within 7 days of IRS announcements. Each calculator footer shows the year and last-verified date. State tax tables are refreshed within 7 days of state DOR updates.
Do these calculators handle state taxes?
The federal calculators (tax, take-home, capital gains) model federal-only. The State Income Tax calculator handles all 50 states plus DC and the major local taxes (NYC, Yonkers, Philadelphia, several Ohio cities). For per-state context, see the State Calculators hub.
What's the difference between a guide and a comparison here?
Guides walk you through a process or formula (e.g., "How to calculate tax brackets"). Comparisons set two or three options against each other with a recommendation framework (e.g., Roth vs Traditional IRA). Use guides to learn; use comparisons to decide.
Why isn't there a calculator for X?
We prioritize by search demand and decision impact. If a calculator you need isn't here, it's on the backlog. The Resources hub may have a guide or topic that covers the math while we work on the tool.
Is anything here financial advice?
No. Every page on Calculover is an educational tool. The math is verified; the application to your situation is yours. For decisions over $50k or with tax/legal consequences, run our numbers, then verify with a CFP, CPA, or attorney.
