NRI Investment Growth Calculator

Understanding the investment growth calculator

Use this compound interest calculator to estimate how a lump sum and recurring contributions may grow. It can help NRIs and Indians abroad model an Indian investment corpus for retirement or another long-term goal without tying the projection to a particular product.

What the inputs mean

• Initial portfolio: money already invested at the start of the projection.
• Contribution and interval: the amount added monthly, quarterly, half-yearly, or yearly.
• Annual return: your assumed effective yearly growth rate before any tax or fees.
• Duration: the full period over which contributions and returns are modelled.

How compounding is modelled

The annual rate is converted to an equivalent monthly rate. Each scheduled contribution is added at the start of its contribution period, then growth is applied monthly. The result separates the amount invested from the estimated return, while the timeline shows how their relative contribution changes over time.

Use a range, not a promise

Real investments rarely grow at a constant rate. Compare cautious, middle, and optimistic assumptions. Monetary inputs and results use your selected currency; non-INR values are converted through INR using the exchange rate entered. This does not model GBP–INR or other currency movements. Inflation, volatility, product charges, and tax are also excluded.
