FAQ

자주 묻는 질문

Q1. What is the difference between simple and compound interest?

Simple interest only accrues on the principal, while compound interest also accrues on previously earned interest — so compound interest grows much larger over longer periods.

Q2. Why does the result change with the compounding period?

At the same annual rate, the more often interest is calculated and added to the principal (daily > monthly > yearly), the slightly larger the final amount becomes.

Q3. Can I calculate regular monthly deposits like a savings plan?

No, this calculator computes a single lump-sum principal compounding over time. Regular monthly contributions need a separate calculation.

Q4. Does this account for taxes?

No. This shows the pre-tax amount without accounting for interest income tax, so your actual payout may be lower.

Q5. Is my input sent to a server?

No. All calculations happen entirely in your browser and are never sent to or stored on a server.
