Required monthly contribution
The projected growth of current assets is calculated first, then the remaining target gap is divided by the future value of month-end contributions.
Target Asset Calculator
How much should you invest
to reach your target assets?
Calculate the monthly contribution required by a target date, then compare when your actual monthly plan may get there.
How it works
Required contributions and
your actual plan are compared.
Estimated date from my plan
The optional monthly contribution is applied under the same assumptions for up to 50 years to find the first month the target is reached.
What the estimate excludes
The monthly return is held constant. Market volatility, taxes, and fees are not included.
Growing $10,000 to $100,000 in 10 years
This example assumes an 8% annual return and contributions made at each month-end.
- Current assets
- $10,000
- Monthly contribution
- $426
- Target assets
- $100,000
The required contribution is rounded up to a whole dollar so the projection does not fall short. The final estimated value may therefore be slightly above the target.
Frequently asked questions
Why can the projected value be slightly above the target?
The monthly contribution is rounded up to a whole currency unit to avoid a shortfall.
What if current assets could reach the target without contributions?
The required monthly contribution is shown as zero, together with the estimated date when growth alone may reach the target.
Does contributing this amount guarantee the target?
No. The estimate assumes a constant return. Actual performance may require changes to the contribution or timeline.
