Assumptions and limits
Change one input at a time, record the assumption, and compare several scenarios.
What the result leaves out
Fees reduce the modeled annual rate before compounding. Compare fees using current account documents.
A useful next step
The inflation-adjusted figure is expressed in today’s dollars using the inflation assumption you enter.
Frequently asked questions
Does this predict my return?
No. It illustrates how chosen assumptions and regular contributions interact. Markets, fees, taxes, and contribution timing can produce different results.
When are contributions added?
The model adds equal contributions at the end of each month and compounds monthly.
What should I enter for return?
Use a range of scenarios rather than treating one rate as expected or guaranteed.
