**calculate**, simply divide your annual gross

**income**by 40. Another rule of thumb is the

**30**% rule, meaning that you can put

**30**%

**of your**annual gross

**income**in rent. If you make $90,000 a year, you can spend $27,000 on rent, and so your monthly rent should be $2,250.

In this manner, how do you calculate 30% of your monthly income?

The general recommendation is to spend about **30**% of your gross **monthly income** (before taxes) on rent. Therefore, if you'll be making $4,000 per **month**, then your rent should be $4,000 x 0.3, or about $1,200. Another **way to calculate** this number is to divide your annual **income** by 40.

Furthermore, how is HUD income calculated? The amount of assistance paid on behalf of the family is **calculated** using the family's annual **income** less allowable deductions. **HUD** program regulations specify the types and amounts of **income** and deductions to be included in the **calculation** of annual and adjusted **income**.

In this way, how do you calculate percentage of income?

Use the following **formula to calculate** a **percentage**: number divided by total **income** times 100 equals the **percentage**. For example, if the number in question is $100, and your total **income** is $1,500, divide 100 by 1,500, and multiply the result by 100 to get the **percentage**.

How do I calculate 10% of my income?

Ten percent is a common starting point since it is the amount traditionally associated with tithing in religious settings. Multiply your monthly **income** by 0.9. This isn't just to test your dusty math skills, but to determine just how much you can live with minus the **10** percent.
