About Fyvnora

Fyvnora is a free collection of financial calculators covering loans, mortgages, investing, taxes and everyday money math.

Our principles:

• Accurate math — formulas match how lenders and institutions calculate.
• Private by design — everything runs in your browser. Your salary, debts and savings are never sent to any server.
• Education first — every calculator explains how the numbers work, not just the answer.

Fyvnora is a sister project of Vortex Games and Vortex Tools.
