Formula Used

Future Value with Contributions

FV = PV×(1+r)^n + PMT×[(1+r)^n – 1]÷r

Variables

PV= Initial investment
PMT= Annual contribution
r= Annual return rate
n= Number of years

Example

$10,000 initial + $6,000/yr at 10% for 20 years = $420,500

Real (Inflation-Adjusted) Return

Real Return = (1 + Nominal) ÷ (1 + Inflation) – 1

Variables

Nominal= Stated annual return
Inflation= Annual inflation rate

Example

(1.10) ÷ (1.03) – 1 = 6.80% real return
