Understanding how banks calculate interest on Savings Accounts and Fixed Deposits is essential for anyone looking to maximize their returns. Let's break down the complexities and dive into the nitty-gritty details of these calculations in simpler language.
Savings Account Interest Calculation
In the past, banks calculated interest on the lowest balance between the 10th and last day of the month. However, since 2010, things have changed. Now, interest on a Savings Account is calculated daily using the formula:
Savings Account Interest=Daily Balance×Rate of Interest×Number of Days365×100Savings Account Interest=365×100Daily Balance×Rate of Interest×Number of Days
Here's a practical example:
Let's say you have a Savings Account with a 4% annual interest rate. In Jan 2024, your account activity looks like this:
Fixed Deposit Interest Calculation
Calculating interest on Fixed Deposits (FD) is a bit different. Let's consider two scenarios for you:
Scenario 1: Holding until Maturity
If you keep your FD for the agreed-upon tenure (let's say 1 year at 8% annual interest), the interest earned is calculated as:
FD Interest=Principal×Rate of Interest×Number of Days365×100FD Interest=365×100Principal×Rate of Interest×Number of Days
For example, if the principal is Rs. 200,000, the interest after one year would be Rs. 16,000.
Scenario 2: Premature Withdrawal
If you decide to withdraw the FD after 6 months, the interest calculation changes. The bank may offer a different interest rate for a 6-month deposit (let's say 6%). Moreover, there might be a penalty, in this case, 0.5%. The effective interest rate becomes 5.5%, and the interest is recalculated using the same formula.
Understanding these calculations empowers you to make informed decisions about your finances. While banks usually handle the math, having a grasp of the process ensures you know what to expect in terms of returns. If you're ever curious or want to double-check, online calculators can be handy tools for your financial planning.
