Understanding This Calculator
Working toward $100K, $500K, $1M, or $5M? Tell us your current savings, monthly commitment, and expected return — then see the exact timeline.
Core Formula
Solve for t: Goal = Current × (1+r)^t + Monthly × [((1+r)^t - 1) / r]
How realistic is a 10% return assumption?
The US stock market averaged ~10% nominal returns over the last century. Use 6-8% as a more conservative planning number for the next 20-30 years.
What's the fastest way to reach my goal?
Three levers: increase monthly savings, earn a higher (but prudent) return, or reduce the target. Savings rate is the one you control most directly.
