About FinCalc

FinCalc is a small set of focused financial calculators built around the same idea: open the page, type your numbers, get an answer. No accounts, no email gates, no tracking beyond anonymous page-view counts.

What we offer

• Compound Interest Calculator — future value with optional periodic contributions.
• Present Value Calculator — discount a future amount to today.
• Loan / Mortgage Calculator — monthly payment and full amortization schedule.
• NPV / IRR Calculator — discount-cash-flow analysis for any series.

Principles

• No accounts. Nothing to sign up for.
• No email capture. We don't even ask.
• Client-side math. Your numbers never leave the browser.
• Shareable URLs. Encode your inputs into a hash and send to a colleague.
• Dark mode. Respects your system preference; toggle to override.
