คำถามที่พบบ่อย — Compound Interest Calculator

Compound interest is interest calculated on both the initial principal and accumulated interest, causing exponential growth over time.
It depends on your financial goals, but a general guideline is to save at least 10-20% of your monthly income. The earlier and more consistently you contribute, the greater the compounding effect.
The tool uses the standard compound interest formula A = P(1+r/n)^(nt). Results are estimates and don't include real-world taxes or fees.
