Estimate how monthly retirement contributions could grow over time using a simple long-term projection.

What this calculator helps you estimate

This calculator shows a simple projection of how monthly retirement contributions could grow over time. It starts from zero and uses an estimated annual return.

The point is not to predict the future perfectly. The point is to see how time, consistency, and investment growth can work together.

Estimate how retirement contributions could grow over time.

How to think about the estimate

Investment returns are not guaranteed. Some years may be positive, some may be negative, and the actual result may be very different from the estimate.

Still, calculators like this are useful because they show the relationship between time and consistent contributions.

Common mistakes

Assuming the return is guaranteed: It is only an estimate.

Ignoring fees and taxes: Real accounts may have plan fees, fund expenses, and tax rules.

Waiting for perfect timing: For many people, the habit of contributing consistently matters more than guessing the perfect moment.
