What this calculation means

Each month applies the annual-equivalent return and proportional asset fee to the existing balance, then adds the contribution. Fee impact is the gap versus the same scenario without fees, including forgone growth. Purchasing power divides the final nominal balance by (1 + inflation)^years.

Assumptions and limits

Constant returns cannot represent market volatility or sequence risk. Excludes taxes, withdrawals, contribution limits, transaction fees and account eligibility. The result is a scenario, not a guaranteed return or a retirement-readiness assessment.
