Frequently Asked Questions
What is the difference between a fixed deposit and installment savings?โผ
A fixed deposit (lump sum) involves depositing the entire amount at once and letting it earn interest for a set period. Installment savings involves making regular monthly deposits that accumulate over time. Fixed deposits earn more total interest because the full amount earns interest from day one, while installment deposits are added gradually.
What is the difference between simple and compound interest for savings?โผ
Simple interest is calculated only on your initial deposit throughout the term. Compound interest calculates interest on the accumulated amount (deposit + previously earned interest). With monthly compounding, interest earned each month starts earning its own interest the next month, resulting in higher returns over time.
Why is the actual interest I receive less than the calculated amount?โผ
The calculator shows pre-tax (gross) interest. In most countries, interest income is subject to tax. For example, in South Korea, 15.4% tax is applied to interest income. Additionally, some financial products may have early withdrawal penalties or fees that reduce the actual amount received. Always check the after-tax return when comparing products.
