On track
Projected Value at Target Date
$20,000.00

How It Works

Formula

PMT=Goal−PV×(1+r12)n(1+r12)n−1r/12\text{PMT} = \frac{\text{Goal} - \text{PV} \times \left(1 + \frac{r}{12}\right)^{n}}{\dfrac{\left(1 + \frac{r}{12}\right)^{n} - 1}{r / 12}}

Variables

PMT\text{PMT}

Required monthly contribution

Goal\text{Goal}

Target savings amount

PV\text{PV}

Current savings already set aside for the goal

rr

Expected annual return rate (decimal)

nn

Number of months until the target date

Enter your target amount, current savings, number of months, and expected annual return. The calculator grows your current savings forward using compound interest, then reverse-engineers the monthly contribution needed to bridge the remaining gap using the future value of an annuity formula.

Frequently Asked Questions

01How is the monthly savings amount calculated?
The calculator first projects what your current savings will grow to by the target date (using compound interest). Then it calculates the remaining gap and uses the annuity formula in reverse to determine the monthly contribution needed to fill that gap.
02What if my current savings already exceed the goal after interest?
If your existing savings will grow past the goal through returns alone, the calculator marks the status as "Already funded" and shows $0 monthly savings needed. The projected value and interest earned over the period are still displayed so you can see how far past the goal your savings are on track to land.
03Should I assume a return rate for my savings?
It depends on where the money is kept and how conservative you want the plan to be. Use the annual return assumption that fits this goal, and compare a lower and higher scenario if you are unsure.
04How does the time horizon affect the amount I need to save?
A longer time horizon usually lowers the monthly contribution because you have more time to save and compound.
05Can I use this for any financial goal?
Yes — emergency funds, house down payments, vacation savings, car purchases, education funds, wedding budgets, or any specific amount you want to reach by a certain date. The math is the same regardless of the goal.
