Interest Calculator FAQ

Understand the power of compound growth. Accurate financial projections and principal calculations powered by kovertiz.

01

Simple vs. Compound Interest?

Simple interest is calculated only on the initial principal. Compound interest is calculated on the principal plus accumulated interest, following the formula $$A = P(1 + r/n)^{nt}$$. kovertiz helps you visualize this exponential growth.

02

Does it support monthly compounding?

Our tool is optimized for annual compounding, the standard for long-term financial planning. For specific monthly or daily frequencies, kovertiz provides precise results based on the compounding periods ($n$) you define.

03

Is my financial data secure?

Yes. kovertiz does not store your figures. All interest calculations are executed via local JavaScript in your browser, ensuring your investment data and net worth figures remain 100% private.

04

How is Simple Interest calculated?

The calculation follows the linear formula $$I = P \times r \times t$$. It is ideal for short-term loans or basic savings where interest doesn't reinvest. kovertiz provides an instant breakdown of the total interest earned.

05

What is the "Rule of 72"?

It is a quick formula to estimate how long it takes to double your investment ($$Years \approx 72 / r$$). You can use kovertiz to verify these estimates with exact mathematical precision for any interest rate.

06

Can I calculate inflation-adjusted returns?

While our tool focuses on nominal growth, you can subtract the inflation rate from your interest rate to get a real return projection. This is a key step for wealth management and retirement planning.
