About Vital

Vital is a growing collection of free health calculators built to help you make smarter money decisions. Whether you're buying a home, planning for retirement, or comparing loans, our tools give you clear, instant answers.

Our Philosophy

• Private. Every calculation runs in your browser. No data is sent to servers, no accounts required. Your financial information stays on your device.
• Visual. Numbers alone aren't enough. We pair every calculator with interactive charts, amortization tables, and visual breakdowns so you truly understand the numbers.
• Free. All calculators are free to use, supported by unobtrusive advertising. No paywalls, no premium tiers, no email walls.

How We're Different

Most financial calculator sites are ad-heavy, slow, and require scrolling past walls of SEO text to get a number. Vital flips that: instant results first, explanations second, minimal ads. We use the same formulas and standards used by banks and financial planners, just presented better.

Standard Formulas

Our calculators use well-established financial formulas:

• Loan/mortgage payments use the standard amortization formula: M = P × [r(1+r)ⁿ] / [(1+r)ⁿ - 1]
• Compound interest uses: A = P(1 + r/n)ⁿᵗ
• Investment returns use time-weighted and IRR methodologies

These are the same calculations used by financial professionals worldwide.
