Plan the side hustle backwards

Start with what you want the side income to do, such as $1,000 a month toward debt or investing, then work back to the effort it takes. Side income is usually self-employment income, so set aside money for tax: in the US that includes both income tax and roughly 15.3% self-employment tax on net earnings, which is why 25% to 30% is a common set-aside. Platform fees, supplies and mileage come off the top too.

At $30 an hour with 25% for tax and 10% for costs, you keep $19.50 an hour, so $1,000 a month takes about 51 hours, or 12 hours a week.
