The calculator will display the future value of your investment, the total interest earned, and a growth chart.

Formula Explained

The future value of an investment is calculated using the compound interest formula:

Future Value Formula

FV = P × (1 + r/n)^nt

Where:

FV = Future Value
P = Principal amount (initial investment)
r = Annual interest rate (in decimal)
n = Number of times interest is compounded per year
t = Time the money is invested for (in years)

This formula accounts for compound interest, which means your investment grows exponentially over time.

Worked Example

Let's calculate the future value of an investment with these parameters:

Initial Investment: $10,000
Annual Interest Rate: 5%
Compounding Frequency: Annually
Investment Period: 10 years

Using the formula:

Calculation

FV = $10,000 × (1 + 0.05/1)^1×10

FV = $10,000 × (1.05)¹⁰

FV = $10,000 × 1.62889

FV = $16,288.90

After 10 years, your $10,000 investment will grow to approximately $16,288.90.

Interpreting Results

The future value result shows how much your investment will be worth after the specified period. Key points to consider:

The higher the interest rate, the faster your investment grows.
More frequent compounding (monthly, quarterly) can significantly increase your returns.
Longer investment periods generally result in greater growth due to compounding.
Inflation and market risks can affect real returns over time.

Important Note

Past performance is not indicative of future results. Investment returns are not guaranteed and may vary.
