This calculator uses the proprietary Rameshta Formula, a copyright-protected mathematical method developed by Rajendra Agrawal. Results reflect the mathematically correct maturity value. Bank displayed amounts may vary due to rounding policies.

Why It Matters

Banks have been
calculating wrong

The formula used by most Indian banks to calculate recurring deposit maturity amounts contains a fundamental mathematical error — it allows the compounding exponent 'n' to be a non-whole number, which violates the principles of compound interest.

Rajendra Agrawal, after thorough research, discovered this error and developed the Rameshta Formula — the only formula that ensures the exponent is always a whole number, producing the mathematically correct maturity value.

Whether your tenure is 14 months, 7 months, or any number that doesn't divide evenly into compounding periods — the Rameshta Formula handles it correctly with its two-part structure.

The Core Insight

When n (number of compounding periods) is not a whole number, the bank formula produces an incorrect result. The Rameshta Formula splits the calculation into a complete-periods part and a remaining-months part, ensuring perfect accuracy every time.

Frequently asked questions

About recurring deposits and the Rameshta Formula

What is a recurring deposit (RD)? +
A recurring deposit is a savings scheme where you invest a fixed amount every month for a fixed tenure. At the end of the tenure, you receive your total investment plus compound interest. It is one of the safest investment options available in India, offered by banks and post offices with tenures ranging from 6 months to 10 years.
What is the Rameshta Formula? +
The Rameshta Formula is a mathematically correct formula for calculating recurring deposit maturity amounts, developed by Rajendra Agrawal. Unlike the formula used by most banks, it ensures the compounding exponent is always a whole number, handles partial compounding periods correctly, and produces results that match manual step-by-step calculation exactly.
Why do bank calculators give different results? +
Most banks use a formula where the exponent 'n' can be a non-integer (e.g., 5/3 for 5 months quarterly). This is mathematically incorrect — compound interest can only be applied for whole-number periods. The Rameshta Formula corrects this by splitting the calculation: it computes complete periods using a whole-number exponent, then adds the remaining months' interest separately.
Is interest on RD taxable? +
Yes. TDS (Tax Deducted at Source) is applicable on recurring deposit interest. If the interest earned on your RD exceeds ₹10,000 in a financial year, the bank will deduct 10% TDS. You should account for this when planning your investment.
What is quarterly compounding for RD? +
Quarterly compounding means interest is calculated and added to your account every 3 months. Most Indian banks compound RD interest on a quarterly basis. This means your effective interest rate is slightly higher than the stated annual rate, as you earn interest on interest every quarter.
Can I use this for post office RD calculations? +
Yes. The Rameshta Formula works for any institution's recurring deposit — banks, post offices, cooperative societies, or NBFCs — as long as you know the interest rate and compounding frequency. Post office RDs typically compound quarterly at rates set by the Indian government.
Is this formula copyrighted? Can banks use it? +
Yes, the Rameshta Formula is an original copyrighted work by Rajendra Agrawal. Commercial use by banks, financial institutions, or software companies without a license is not permitted. If you are a bank or fintech company interested in licensing this formula or API access, please contact us.
