Funds can charge in several ways: a front-end load when you buy, yearly operating expenses, hidden trading costs from portfolio turnover, and a back-end fee when you sell. Together they can cost more than a third of your potential wealth over decades.
How to use the Investment Fee Calculator
- Initial investment
- Sales load (front-end)
- Annual return
- Annual operating fees
- Turnover (trading) costs per year
- Redemption fee
- Investment duration
Results update as you type, and every field accepts the units shown in its menu.
How it works
Enter the initial investment, sales load, annual return, operating fees, turnover costs, redemption fee and investment period.
Tips
- Use the nominal annual rate and pick the compounding frequency your bank or broker states.
- Small differences in return or fees compound into large differences over decades.
- Run the calculation with a cautious, a central and an optimistic return to see the range of outcomes.
- Past returns do not guarantee future returns – nothing here is investment advice.
Common mistakes to avoid
- Comparing an APR with an APY or effective rate.
- Ignoring inflation, taxes and fees when judging a real return.
- Entering a percentage as a decimal (5 instead of 0.05 is correct here).
Inputs explained
| Field | What to enter |
|---|---|
| Initial investment | Amount in your currency |
| Sales load (front-end) | In % |
| Annual return | In % |
| Annual operating fees | In % |
| Turnover (trading) costs per year | In % |
| Redemption fee | In % |
| Investment duration | Units: years, months |
What each result means
- Invested amount = [Initial investment]×(1 – [Sales load (front-end)]÷100)
- Effective return = ((1 + [Annual return]÷100)×(1 – ([Annual operating fees] + [Turnover (trading) costs per year])÷100) – 1)×100
- Fund value before redemption = [Invested amount]×(1 + [Effective return]÷100)^[Investment duration]
- Final fund value = [Fund value before redemption]×(1 – [Redemption fee]÷100)
- Fund value without fees = [Initial investment]×(1 + [Annual return]÷100)^[Investment duration]
- Total fees = [Fund value without fees] – [Final fund value]
Example values
How the main result changes when Initial investment changes and everything else stays at the example values above:
| Initial investment | Final fund value |
|---|---|
| 5,000 | 7,457.36 |
| 7,500 | 11,186.04 |
| 10,000 | 14,914.72 |
| 12,500 | 18,643.4 |
| 15,000 | 22,372.08 |
| 20,000 | 29,829.44 |
Formula
Invested amount = initial × (1 − sales load)Effective return = (1 + return) × (1 − operating fees − turnover costs) − 1Final value = invested × (1 + effective return)^years × (1 − redemption fee)Worked example
Inputs — Initial investment: $10,000; Sales load (front-end): 2 %; Annual return: 10 %; Annual operating fees: 2 %; Turnover (trading) costs per year: 3 %; Redemption fee: 2 %; Investment duration: 10 years.
Results — Invested amount = $9,800.00; Effective return = 4.5 %; Fund value before redemption = $15,219.10; Final fund value = $14,914.72; Fund value without fees = $25,937.42; Total fees = $11,022.71.
