# Lumpsum Calculator

> See how a one-time investment could grow at different return rates.

Interactive calculator: https://awesomecalcs.com/lumpsum-calculator

## How this is calculated

Projects the future value of a one-time (lumpsum) investment compounding annually at a fixed expected rate of return.

**Formula:** `A = P x (1 + r/100)^n`

**Variables:**

- `A`: Maturity value
- `P`: One-time invested amount, in INR
- `r`: Expected annual rate of return, as a percentage
- `n`: Number of years invested

Reference: Validated against Groww and ET Money lumpsum return calculators.

## Assumptions

- Assumes annual compounding at a constant rate of return for the full investment period.
- Does not account for taxes, exit loads, or expense ratios that reduce actual mutual fund returns.

- `amount` (number (1000 to 10000000 INR), default `100000`): One-time invested amount.
- `rate` (number (1 to 30 %), default `12`): Expected annual rate of return.
- `years` (number (1 to 40 years), default `10`): Investment duration.

## Frequently asked questions

### What is a lumpsum investment?

A lumpsum investment is a one-time investment of a fixed amount in a mutual fund, rather than spreading it out over time. For example, investing ₹1,00,000 as a lumpsum at 12% expected annual returns for 10 years could grow to roughly ₹3,10,585, of which ₹2,10,585 is estimated returns.

### Are lumpsum returns guaranteed?

No. Lumpsum investments go into mutual funds, so returns depend on market performance and are not guaranteed. The expected return rate here is just an assumption you can adjust to see different scenarios.

### How is the maturity value calculated?

We use the standard lumpsum future-value formula: A = P x (1 + r/100)^n, where P is your invested amount, r is the expected annual rate of return, and n is the number of years invested. Your money compounds once a year for the chosen time period.

### Lumpsum vs SIP: which is better?

It depends on whether you already have the money or are earning it over time. A lumpsum invests everything immediately, so it benefits the most from compounding when markets rise, but it also carries more timing risk if you invest right before a downturn. A SIP spreads your investment across market ups and downs. If you have a windfall (like a bonus) and a long time horizon, a lumpsum often works well; if you're investing from your salary, a SIP is usually more practical.

### Can I add more money to a lumpsum investment later?

Yes, most mutual funds let you make additional purchases at any time. If you plan to invest a large amount now and add smaller amounts regularly afterwards, you can use this calculator for the initial lumpsum and the SIP calculator to model the recurring additions separately.
