Turning a goal into a monthly habit
A large target feels manageable once it is broken into a regular monthly amount. By accounting for the interest your money earns along the way, the calculation shows a realistic figure rather than simply dividing the goal by the number of months, which would ignore growth and overstate what you need.
Why starting savings matter
Money you have already set aside keeps compounding for the entire period, so a healthy starting balance can sharply reduce the monthly contribution required. The longer your timeline and the higher your return, the more of the goal is met by growth rather than fresh deposits.
