How much to save monthly to reach $500k in 40 years?
To reach $500,000 in 40 years at a 7% average annual return, save about $190 a month. You'd put in $91,435 of your own money. Compounding adds the other $408,565.
The earlier you start, the more compounding does for you. Over 40 years at a 7% average annual return, $190/month grows to $500,000, and only $91,435 of that is money you contributed.
Stretch the horizon and the monthly number drops fast, because your earlier dollars have longer to compound. These are nominal figures, before inflation.
