Investment Growth Calculator
Enter a lump sum, expected annual return, and number of years. See how much your investment could grow. Assumes compound growth with no additional deposits.
Future value of lump sum
Enter values to calculate.
How it works
Future value = Principal × (1 + r)^n, where r is the annual rate (as a decimal) and n is years. We use annual compounding for simplicity; monthly would give slightly higher results.
When to use it
Use it to project a current balance, to see the impact of rate or time, or to set a target for a lump-sum investment.
Frequently asked questions
Is this guaranteed?
No. Returns vary. Use for illustration and planning only.
What about taxes?
