🤔 How this calculator is different

Most calculators use a monthly formula that approximates daily compounding. This one actually loops through every single day using real dates – that's true daily compounding. It also adjusts for inflation and lets you pick any currency.

Is this really free?

Yes. No credit card, no signup, no "premium". Just honest numbers.

What does "true daily compounding" mean?

We calculate interest every single day using the exact daily rate. That's how real high‑yield accounts work.
