Common questions

What is the difference between compound and simple interest?

Simple interest is paid only on your original amount. Compound interest is also paid on past interest, so growth accelerates over time — try both tools with the same numbers.

Is the rate guaranteed?

No — this is a fixed-rate estimate. Real products change rates and may deduct tax/zakat.
