Portfolio Cost Analysis
The return you earn is only part of the return you keep.
Examine recurring portfolio costs, separate gross performance from retained return, and understand how fee structures change the economics of long-term capital.

Cost Analysis
Map every recurring cost before evaluating performance.
A portfolio's cost structure is easier to evaluate when each layer is separated. The analysis below frames the annual drag against the capital being managed rather than treating fees as an isolated percentage.
Analytical principle
Compare the return retained after costs, not simply the headline return before costs.
Cost Structure
Portfolio cost stack
Fund expense
Operating expenses charged within the investment vehicle
Advisory fee
Portfolio-level management or advisory cost
Transaction drag
Estimated annual effect of portfolio trading activity
Total annual cost
Combined recurring cost stack
Portfolio Modeling
Expense ratio impact over time.
Model the difference between a portfolio exposed to an annual expense ratio and an otherwise identical portfolio with no recurring fund cost.

Net Return Analysis
Strip away the cost layers to see retained return.
Gross performance is only the starting point. Apply recurring fund, advisory and transaction assumptions to arrive at a clearer net-return view.

Cost Intelligence
The important comparison is what remains after the cost structure.
Cost analysis becomes more useful when viewed alongside the investment horizon, portfolio size and expected return. The same fee can have a very different dollar consequence at different capital levels.
0.15%
Lower recurring costs can leave more of the portfolio's gross return available for compounding.
0.50%
A moderate expense structure should be evaluated against the exposure, service and return characteristics it supports.
1.00%
Higher recurring costs create a larger hurdle for the portfolio to overcome before investors receive equivalent net results.
Research View
Fee analysis should sit beside allocation analysis.
A lower-cost fund is not automatically the stronger portfolio choice. The useful comparison considers exposure, benchmark, risk characteristics, liquidity and the amount of return retained after costs.
Methodology
Keep the arithmetic visible.
FundMonitor's fee analysis separates gross return assumptions from recurring cost assumptions so the relationship between performance and retained return remains visible. Calculator outputs are mathematical projections based on the values entered and should not be interpreted as forecasts of actual investment performance.
