Projecting revenue involves figuring out what you’re going to charge for your product or service and how many customers you can attract.

Here’s an example: If a landscaper plans to charge $25 to mow a lawn and has contracts with 40 people to mow once a week, the estimated weekly revenue would be $1,000 and the estimated monthly mowing revenue would be $4,000.

Though your primary revenue may be from a single source, you may project some additional revenue from related work.

If the landscaper lived where it snows, there might be money to be made in snow removal.

When you project revenue, you may want to estimate annual as well as monthly income . One reason is that in some businesses, the revenue increases or decreases at certain times of year. It helps to anticipate that in creating your budget.

Now it's time to think about start-up costs.
