Investment Strategy
- • Start investing early to maximize compound growth
- • Invest regularly regardless of market conditions
- • Choose investments that match your risk tolerance
- • Diversify across different asset classes
- • Review and rebalance your portfolio periodically
- • Consider tax-advantaged accounts (401k, IRA)
How it works
Future value answers “what will this be worth later?” It grows a present amount — and optionally a stream of regular contributions — forward at a compounding rate. It's the core of every savings, investment, and retirement projection: money has a time value because a dollar today can be invested to become more than a dollar tomorrow.
Future value
FV = PV(1 + r)ⁿ + PMT · [(1 + r)ⁿ − 1] / r
- FV
- future value
- PV
- present value (today's amount)
- PMT
- contribution per period (0 for a lump sum)
- r
- rate per period
- n
- number of periods
Worked example
- Present value PV = $5,000
- Rate = 6% per year
- No contributions, 15 years
- FV = 5,000 × (1.06)¹⁵
- FV = 5,000 × 2.397
Future value ≈ $11,983 — the $5,000 more than doubles over 15 years.
Good to know
- Two levers dominate: the rate and the number of periods. Doubling the horizon does far more than doubling the rate because growth is exponential.
- Future value is nominal — to compare with today's prices, discount it back by inflation to get real value.
- The mirror image is present value (PV = FV ÷ (1+r)ⁿ): what a future sum is worth today.
