FD vs Gold vs Spare8+

Same ₹1,00,000. Same 5 years.

An FD locks in a fixed rate. Gold has grown faster over the long run, and Spare8+ adds a fixed 5% reward on top of gold's growth.

Post Office figures include annual payouts without reinvestment; gold and Spare8+ figures are end-of-term projections.

Guide

What is an FD calculator?

A Post Office Time Deposit accepts a lump sum for an initial term of 1, 2, 3 or 5 years. This calculator estimates annual interest payouts and the principal returned at maturity.

Interest is calculated quarterly and paid annually. Interest already due for payment does not earn further interest in the Time Deposit account. The calculator shows interest after simplified tax and compares total payouts with 24K gold and Spare8+ projections.

How to use it

  1. Enter your deposit: type it or tap a preset.
  2. Choose 1, 2, 3 or 5 years to apply the matching scheme rate.
  3. Review annual interest payouts and the principal returned at maturity.
  4. Pick your tax slab to see what you keep after tax.

Post Office annual payout formula

Total principal + interest payouts = P + I × t. Principal returned at maturity = P. Annual payouts are not reinvested.

Where profits meet peace of mind.

Buy 24K gold from ₹10 and explore eligible Spare8+ leasing opportunities. Available reward rates and terms are shown in the app, and the rupee value of gold can rise or fall.

Methodology: Interest is calculated quarterly and paid annually. Interest already due for payment does not earn further interest in the Time Deposit account. Annual interest is rounded to the nearest rupee (half a rupee rounds up), then multiplied by the selected 1, 2, 3 or 5-year term. Total principal + interest payouts includes the original principal and these annual payouts without reinvestment; gold and Spare8+ figures are end-of-term projections. The tax option applies a simplified slab percentage to FD interest only and excludes cess, surcharge, TDS timing and individual circumstances. Gold and Spare8+ comparisons use expected annual returns of 11% and 5%, not a prediction or promise. They exclude 3% GST, spreads, fees and taxes. Review current product terms and consider professional advice before acting.
