Savings Goal Calculator
Use this savings goal calculator to estimate how much to set aside each month to reach a target by a chosen date, given what you have already saved and an assumed annual return. It is a planning estimate, not a guarantee, because real returns, taxes, fees, inflation, and irregular contributions can change the result.
How to use this calculator
- Enter your target amount and how much you have already saved toward it.
- Set the number of years until the goal and a conservative annual return assumption.
- Use the required monthly contribution as a planning target, then test lower return assumptions before relying on one result.
Formula
- Monthly rate = annual return rate / 12
- Future value of current savings = current savings x (1 + monthly rate)^months
- Remaining amount = target amount - future value of current savings
- Required monthly contribution = remaining amount x monthly rate / ((1 + monthly rate)^months - 1)
Example calculation
To reach $50,000 in 5 years with $5,000 already saved and a 4% annual return assumption, you would need to save about $662 per month. Contributions total roughly $44,700 and estimated growth is about $5,300.
How to interpret the results
- Read the required monthly contribution as a planning target that assumes steady saving and a fixed return rate.
- Test a lower return assumption and a longer time period, because both reduce how much you must save each month but change the risk and time involved.
- The estimate does not include taxes, fees, or inflation, so the real amount needed to maintain buying power may be higher.
Frequently asked questions
What return rate should I use?
Use a conservative assumption you are comfortable with. A lower return rate increases the required monthly contribution but reduces the risk of falling short of the goal.
What if I have not saved anything yet?
Enter zero as current savings. The calculator will then estimate the full monthly contribution needed to reach the target from a zero starting balance.
Does this guarantee I will reach the goal?
No. It is a planning estimate based on a fixed return assumption. Real returns vary, and contributions or timelines may change.
