Assumes a constant return compounded monthly, contributions at month-end, and no taxes or fees.
The three levers
Ending value is driven by time in the market, contribution rate, and return — in roughly that order for most savers. Doubling the timeline usually beats doubling the return assumption, because compounding is exponential in time but only polynomial in rate.
Real vs. nominal
An 8% nominal return is roughly 5% after typical inflation. If you want the answer in today's purchasing power, enter a real return (nominal minus expected inflation) instead — the math is identical, the interpretation changes.
