Ending balance$75,578
after 20 years at 4.0% (monthly compounding, deposits at month-end)
Total contributed$49,000
$1,000 start + $200 × 240 months
Growth from interest$26,578
Interest did 35% of the work. Stretch the years, not the monthly amount, and watch that share climb — time is the active ingredient.
A fixed rate for decades is a simplification: savings rates float and investments swing. Use it to compare scenarios, not to predict a balance.
