About HYSA Calculator

Our Mission

HYSA Calculator exists to help people make informed decisions about their savings. We believe everyone should have free access to powerful financial tools that demystify compound interest and help visualize long-term savings growth.

What We Do

Our calculator provides accurate, instant projections for high-yield savings accounts (HYSAs) using daily compounding calculations. Whether you're:

  • Building your first emergency fund
  • Saving for a down payment on a house
  • Planning for retirement
  • Comparing different savings strategies

...our tool helps you see exactly how much your money can grow over time.

Why We Built This

Traditional savings calculators often:

  • Use monthly or annual compounding instead of daily
  • Don't account for regular monthly deposits
  • Have cluttered interfaces that confuse users
  • Lack real-world scenarios for comparison

We created HYSA Calculator to address these gaps with accurate daily compounding, an intuitive interface, and practical examples that reflect real savings goals.

Our Commitment to Accuracy

Daily Compounding: We use n=365 in our calculations to match how most HYSAs actually compound interest.

Transparent Math: Our calculation formula is based on standard compound interest equations used by financial institutions.

No Hidden Assumptions: What you see is what you get—we don't factor in fees, minimum balances, or other bank-specific requirements unless explicitly stated.
