Save $100,000 in 3 Years
This page works backward from $100,000. Give it 3 years and a rate of 4 percent and it finds the deposit.
The deposit comes to $2,619.07 a month. Interest covers $5,714 of the goal.
How the deposit is worked out
First find how much an empty account will grow to on its own over 36 months. Subtract that from the goal of $100,000 to get the gap. The monthly deposit is the gap times the monthly rate of 0.3333 percent, divided by the growth factor minus one. The growth factor is one plus the monthly rate raised to the power of 36.
