What this means

Use the result with context.

Compound estimates are most useful for understanding the role of time and consistency. The annual return is an assumption, so use conservative numbers and review your plan regularly.

Practical example

Small monthly habits can compound.

If you invest €200 per month for 20 years, the result depends heavily on the return assumption and consistency.

What to do next

Turn the estimate into a goal.

Use the Finance Tracker to create a long-term goal and update progress when you add new contributions.
