Frequently asked questions
What return should I assume?
Use a modest long-term average and keep expectations realistic; markets vary year to year.
Does contribution frequency matter?
Regular contributions compound over time and often outweigh the starting amount.
Are these guarantees?
No — they're projections based on your inputs, not promised outcomes.
