> The investment fee calculator shows how sales loads, yearly operating fees, trading (turnover) costs and redemption fees eat into a fund investment – the effective return, final value, total fees and what you would have without fees.

## Inputs

- Initial investment
- Sales load (front-end) (%)
- Annual return (%)
- Annual operating fees (%)
- Turnover (trading) costs per year (%)
- Redemption fee (%)
- Investment duration (years, months)

## Results

- Invested amount
- Effective return
- Fund value before redemption
- Final fund value
- Fund value without fees
- Total fees

## Formula

```
Invested amount = initial × (1 − sales load)
Effective return = (1 + return) × (1 − operating fees − turnover costs) − 1
Final value = invested × (1 + effective return)^years × (1 − redemption fee)
```

## Explanation

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).

### 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:

## 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.

## FAQ

**What is a sales load?**
A commission charged when you buy (front-end) or sell (back-end) fund shares.

**What is turnover cost?**
Trading costs inside the fund from buying and selling securities.

**How can I keep fees low?**
