Management Expense Ratio Formula

The following formula is used to calculate the management expense ratio (MER) for a given set of financial values.

MER = (TMF + TOE) / (TA)

Variables:

  • MER is the management expense ratio as a decimal in this formula; multiply by 100 for percent (0.015 = 1.5%)
  • TMF is the total management fees
  • TOE is other annual operating expenses, excluding management fees already included in TMF; include applicable taxes once
  • TA is annual average net assets, in the same currency as the annual costs

To calculate the management expense ratio, add the total management fees and total operating expenses, then divide the result by the total assets.

What is a Management Expense Ratio?

The management expense ratio (MER) is a measure of the total costs associated with managing and operating an investment fund, expressed as a percentage of the fund's annual average net assets. These costs typically include management fees, operating expenses, and other administrative costs. The MER is an important metric for investors as it provides insight into the cost efficiency of a fund. A lower MER indicates a more cost-effective fund, while a higher MER suggests higher expenses relative to the fund's assets.

How to Calculate Management Expense Ratio?

The following steps outline how to calculate the Management Expense Ratio.

  1. First, determine the total management fees (TMF).
  2. Next, determine the total operating expenses (TOE).
  3. Next, determine annual average net assets (TA), using the same currency as the annual costs.
  4. Finally, calculate the Management Expense Ratio using the formula MER = (TMF + TOE) / TA.
  5. After inserting the values and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Total Management Fees (TMF) = $10,000

Total Operating Expenses (TOE) = $5,000

Annual average net assets (TA) = $1,000,000. Annual fees of $10,000 plus other expenses of $5,000 give MER = 0.015, or 1.5%.
