Question 1

What is future value in finance?

Accepted Answer

Future value (FV) is the value of an investment at a specified date in the future, based on an assumed growth rate. It shows what money invested today will grow to over time, considering compound interest and regular contributions.

Question 2

How is future value calculated?

Accepted Answer

Future value is calculated using: FV = PV × (1 + r/n)^(n×t) + PMT × [((1 + r/n)^(n×t) − 1) / (r/n)], where PV is present value, r is the annual interest rate, n is compounding frequency, t is time in years, and PMT is the periodic payment.

Question 3

What is the Rule of 72?

Accepted Answer

The Rule of 72 estimates how long it takes to double your money: divide 72 by your annual interest rate. At 8% annual return, your investment doubles in roughly 9 years (72 ÷ 8). It's a quick mental-math shortcut for compound growth.

Question 4

Does compounding frequency affect future value?

Accepted Answer

Yes, more frequent compounding produces slightly higher future values. Daily compounding grows more than monthly, which grows more than annual. However, the difference diminishes at higher frequencies — the rate and time invested matter far more.

Question 5

What annual return rate should I use in this calculator?

Accepted Answer

Historically the S&P 500 has returned about 10% annually before inflation (≈7% inflation-adjusted). Conservative investors often use 4–6%, moderate investors 6–8%, and equity investors 8–10%. Always match the rate to your specific investment type and risk tolerance.
