The Ultimate Guide to Monthly Interest Calculations
Whether you are a retiree relying on the Post Office Monthly Income Scheme (POMIS), an investor parking funds in a Fixed Deposit (FD), or someone taking a loan from a local lender, knowing your Monthly Interest is crucial. While banks quote rates "Per Annum" (Yearly), our daily expenses happen monthly. Toolvala.in's Monthly Interest Calculator bridges this gap, helping you convert annual rates to monthly payouts instantly.
This guide covers everything from bank formulas to the traditional "Village Interest" system used across India.
Why Calculate Monthly Interest?
Understanding your monthly cash flow is the foundation of financial planning. Here is why you need this tool:
- Income Planning: If you have ₹10 Lakhs in an FD, how much will it contribute to your monthly household budget?
- Loan Reality Check: A loan agent might say "only 1.5% interest," but if that is per month, you are paying a massive 18% per year!
- Investment Comparison: Compare a monthly payout scheme vs. a cumulative scheme to see which serves your liquidity needs better.
How to Calculate Monthly Interest? (The Formula)
The calculation depends on how the interest rate is quoted.
Scenario 1: Bank / Formal Institutions (Yearly Rate)
Banks always quote interest per annum (p.a.). To find the monthly payout:
Example: ₹1,00,000 at 12% p.a.
Calculation: (1,00,000 × 12) / 1200 = ₹1,000 per month.
Scenario 2: Village / Informal Loans (Monthly Rate)
In many parts of India, interest is quoted as "2 rupees interest" or "3% interest". This usually implies a monthly rate.
Example: ₹1,00,000 at 2% per month.
Calculation: (1,00,000 × 2) / 100 = ₹2,000 per month.
Note: This is equivalent to 24% per annum!
Popular Monthly Income Schemes in India
1. Post Office Monthly Income Scheme (POMIS)
A government-backed scheme where you deposit a lump sum and receive interest every month. The current rate (as of 2024) is around 7.4% p.a. Use our calculator to see exactly how much you will get for a deposit of ₹5 Lakhs or ₹9 Lakhs.
2. Bank Fixed Deposits (Non-Cumulative)
When opening an FD, you can choose the "Monthly Payout" option. However, banks often apply a "discounted rate" for monthly payouts compared to quarterly payouts. This tool helps you verify the credit amount.
3. Senior Citizen Savings Scheme (SCSS)
Designed for retirees, this scheme offers quarterly payouts, but you can use this calculator to find the monthly equivalent to plan your budget.
