The drag is bigger than the fees: every dollar paid in year one also forfeits its growth for every year after.

Model assumptions

  • Annual compounding; contributions at the start of each year; MER charged on the average of start and end balance.
  • Growth rate is constant — real markets are not, but the fee comparison holds because both paths face the same returns.
  • Educational estimate, not investment advice.

Sources

  • Methodology: standard compound-growth math, no regulatory source required. Fee drag compounds over time — the MER is modeled as an annual charge on the average balance plus flat commissions, against an identical fee-free path.
