How it works
The calculator grows current savings first, then treats contributions as an ordinary annuity deposited at each month’s end. At 0% it uses simple division. Returns and savings rates can change, so the projection is an estimate rather than a guarantee.
Worked example
With no interest, growing $1,000 to $7,000 in 24 months requires ($7,000 − $1,000) ÷ 24 = $250 per month.
