See the following Indiana law about wage garnishments: IC 24-4.5-5-105.

If a creditor gets a judgment entered against you in a court of law in Indiana, they can garnish 25% of your disposable earnings for each week. Disposable earnings is sometimes called “take-home pay.” Disposable earnings is the amount left over after legally required deductions. You can attempt to get the garnishment amount lower than 25% upon a showing of good cause. For a second calculation, you can see how much your disposable earnings for the week are over 30 times the federal minimum wage. If your second calculation is less than the 25% amount, the second calculation will be your garnishment amount.
