It supports all official tenures, current interest rates, quarterly compounding, and shows a clear year-wise breakdown of returns.

What Is National Savings Time Deposit?

National Savings Time Deposit (TD) is a government-backed fixed deposit scheme offered through Indian Post Offices. It works similarly to a bank fixed deposit but is backed by the Government of India.

When Was National Savings Time Deposit Introduced?

The Post Office Time Deposit scheme has been available for decades as part of India’s small savings schemes, designed to provide safe and predictable returns to investors.

The calculator automatically adjusts the interest rate when you select a tenure, matching real Post Office TD rules.

How National Savings Time Deposit Returns Are Calculated

The Post Office TD maturity amount is calculated using quarterly compounding.

Formula Used

A = P × (1 + r / 4)^(4 × t)

Where:

• A = Maturity value
• P = Investment amount
• r = Annual interest rate
• t = Tenure in years

This formula is applied year by year to generate an accurate schedule.

Example

Suppose you invest ₹50,000 in a 2-year National Savings Time Deposit at 7.0% interest.

• Investment amount: ₹50,000
• Tenure: 2 years
• Interest rate: 7.0%
• Compounding: Quarterly

Result

• Maturity value: ~₹57,300
• Total interest earned: ~₹7,300

The calculator shows:

• Exact maturity value
• Interest earned
• Year-wise opening balance, interest, and closing balance
