Father (52) and daughter (24) both want to save up $250,000 by age 60, both at 8 % return. The father has 8 years, the daughter 36 years.
ℹ What is computed is the daughter's rate (36 years). With only 8 years the father would need many times as much.
Change any number and press "Calculate" – or use "Type in" on the right to watch it entered step by step.
Time beats money dramatically: the daughter reaches the same goal with a fraction of the father's rate. Quadrupling the saving time does not demand a quarter, but less than a twentieth of the rate.
Here the final-value formula is solved for the rate: you divide the target by the compounding factor (qⁿ−1)/(q−1), which shows the multiple to which a rate of $1 grows. Takeaway: the longer n, the larger this factor – and the smaller the rate needed.
