#### The theory behind…

### Calculating Expected Returns.

Let’s have a look how expected returns on The Graph Network are calculated in theory. You can skip right ahead if you want to see the reward calculation in practice.

### Factors that determine delegation return.

## Formulas.

#### Calculating Indexer Rewards

If you want to calculate your expected indexing rewards by hand, you can use this formula:

#### Calculating Query Fees

The formula for calculating expected query fees is as follows:

#### Reward calculation in practice

### Reward Calculators.

There’s no need for you to calculate expected rewards per hand. Simply use one of the available calculators.

### Graphscan.io.

An easy to use calculator is provided by Graphscan.io. Simply enter your planned delegation, click calculate and see an estimate of your APY and your estimate daily returns in GRT for each indexer.

### Reward.suntzu.me.

If you like to compare the estimated returns with another calculator, you can use Reward.suntzu.me. The procedure is just the same. Insert the amount of GRT you plan on delegating and the calculator will show you an estimate.

## Simplified reward calculator.

#### Proudly brought to you by The Graph Academy

We’ve created an easy-to-use calculator that shows you how much GRT you can earn per day with each indexer. The spreadsheet also has a functionality that shows you after how many days of delegating you break even.

Enter the amount of GRT you wish to delegate and head over to the sheet called `Reward Calculator`

and you will see your potential delegation rewards for each indexer.
