Frequently Asked Questions
How is savings interest rate calculated?
Savings interest is calculated using the simple interest formula: Interest = Principal x Rate x Time / 100. For example, ₹10,000 at 4% for 3 years earns ₹1,200 in interest (10000 x 4 x 3 / 100 = 1200). The final amount is the principal plus the interest earned.
What is the difference between simple interest and compound interest?
Simple interest is calculated only on the principal amount using the formula P x R x T / 100, while compound interest is calculated on both the principal and previously earned interest. Simple interest grows linearly, while compound interest grows exponentially over time. Savings accounts typically use daily compounding, but simple interest is easier to calculate for fixed-term deposits.
What are the current savings account interest rates in India?
Savings account interest rates in India range from 2.70% to 7.00%. Major banks like SBI offer 2.70-3.00%, HDFC Bank 3.00-3.50%, and ICICI 3.00-3.50%. Small finance banks offer higher rates: AU Small Finance Bank (up to 7%), Ujjivan (up to 6.50%). Fixed deposits offer higher rates from 5% to 8.50% depending on tenure.
How much interest will I earn on ₹1 lakh at 4% for 5 years?
On ₹1,00,000 at 4% simple interest for 5 years, you will earn ₹20,000 in total interest (1,00,000 x 4 x 5 / 100 = 20,000). The final amount after 5 years will be ₹1,20,000. If compounded monthly instead, the final amount would be slightly higher at approximately ₹1,22,099.
Is savings interest taxable in India, US, and UK?
In India, savings interest is taxable as Income from Other Sources, with a deduction up to ₹10,000 under Section 80TTA (₹50,000 for senior citizens under Section 80TTB). In the US, savings interest is taxed as ordinary income at your marginal rate, with Form 1099-INT issued if interest exceeds $10. In the UK, each person has a Personal Savings Allowance of £1,000 (basic rate) or £500 (higher rate) before tax applies.
Can I use this calculator for loan interest calculations?
Yes, this calculator uses the simple interest formula which applies to both savings and loans. For simple interest loans like car loans or personal loans, enter the loan amount as principal, the annual interest rate, and the loan tenure in years. The calculator shows the total interest payable and the final repayment amount.
What interest rate can I expect on a US high-yield savings account?
US high-yield savings account rates in 2024-2025 range from 3.50% to 5.25% APY, depending on the Federal Reserve rate.

How can I maximize my savings interest earnings?
Maximize savings interest by: 1) Choosing high-yield accounts from online banks or small finance banks offering 4-7% rates, 2) Using fixed deposits or CDs for higher fixed rates on lump sums, 3) Taking advantage of compound interest by leaving interest in the account, 4) Comparing rates across banks quarterly, and 5) Using sweep-in FD facilities that automatically transfer excess balance to higher-interest deposits.
