Key Concepts

Present Value (PV)
The current value of money invested today, serving as the starting point for future value calculations.
Compound Interest
Interest calculated on both the principal and previously earned interest, leading to exponential growth.
Compounding Frequency
How often interest is calculated and added to the principal (annually, monthly, daily, etc.).
Inflation Impact
The reduction in purchasing power over time, affecting the real value of future money.

How to Calculate Future Value

Formulas

Basic Future Value: FV = PV × (1 + r)^n
With Regular Contributions: FV = PMT × [((1 + r)^n - 1) / r] + PV × (1 + r)^n
Real Future Value: Real FV = FV / (1 + inflation)^n
Where: PV = Present Value, r = Interest Rate, n = Periods, PMT = Payment

Calculation Steps:

  1. 1
    Determine Input Values
    Present value, interest rate, time period, and contribution amount
  2. 2
    Calculate Compound Interest
    Apply the compound interest formula based on frequency
  3. 3
    Add Regular Contributions
    Include the future value of periodic payments
  4. 4
    Adjust for Inflation
    Calculate real future value by accounting for inflation

Important Considerations

⚠️ Investment Risk Disclaimer

Past performance does not guarantee future results. Consider your risk tolerance and investment objectives.

📈 Market Volatility

Real returns may vary significantly from projected returns due to market fluctuations.

  • • Consider diversified investment strategies
  • • Review and rebalance periodically
💰 Tax Implications

Taxes on investment gains can significantly impact net returns.

  • • Consider tax-advantaged accounts
  • • Factor in capital gains taxes
🕐 Time Value of Money

Money today is worth more than the same amount in the future.

  • • Start investing early for maximum benefit
  • • Regular contributions compound over time
📊 Inflation Risk

Inflation erodes purchasing power over time.

  • • Use real (inflation-adjusted) returns
  • • Consider inflation-protected investments

Frequently Asked Questions

What is future value in finance?
Future value (FV) is the value of an investment at a specific point in the future, calculated using compound interest. It shows how much money invested today will be worth after earning interest over time.
How is future value calculated?
The basic formula is FV = PV × (1 + r)^n, where PV is present value, r is annual interest rate, and n is number of years. For regular contributions, the formula includes additional terms for periodic payments.
What's the difference between simple and compound interest?
Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus previously earned interest. Compound interest grows exponentially over time.
How does compounding frequency affect future value?
More frequent compounding (monthly vs annually) results in higher future values because interest is calculated and added more often. The effective annual rate increases with compounding frequency.
Should I consider inflation in my calculations?
Yes, inflation reduces purchasing power over time. Use real (inflation-adjusted) interest rates for more accurate long-term planning. The calculator can adjust for inflation to show real future value.
