What Is Future Value?

Future Value (FV) is the value of a current asset at a specified date in the future, assuming a certain rate of growth. It is a core concept in the time value of money — the idea that a dollar today is worth more than a dollar tomorrow, because today’s dollar can be invested and earn returns.

Lump Sum Future Value

If you invest a single amount today (a lump sum):

FV = PV × (1 + r/n)^(n×t)

Where:

• PV = Present value (lump sum today)
• r = Annual interest rate (as a decimal)
• n = Compounding periods per year (12 for monthly, 4 for quarterly, 1 for annually)
• t = Time in years

Regular Contribution Future Value (Annuity)

If you make regular contributions (like a monthly savings deposit):

FV = PMT × [(1 + r/n)^(n×t) − 1] / (r/n)

Where PMT is the contribution per period.

Compounding Frequency Effect

More frequent compounding means more interest on interest:

The difference between monthly and daily compounding is small; the difference between annually and monthly is more meaningful over long periods.

The Power of Starting Early

Starting 10 years earlier can more than double your final wealth. Consider:

• Investor A invests $500/month at 8% for 30 years → $679,700
• Investor B invests $500/month at 8% for 20 years → $294,510

Investor A ends up with 2.3× more by starting a decade earlier.

Real vs. Nominal Returns

These calculations show nominal (before-inflation) returns. To find the real return, subtract the expected inflation rate from your annual rate. For example, 7% nominal minus 3% inflation = 4% real annual return.
