How Much Side Income Do I Need?
Most people do not need side income in the abstract. They need a number: the gap between what goes out and what comes in. Start there.

Name the gap
List fixed monthly outflows: rent, minimum debt payments, childcare, insurance, and anything you cannot skip. Subtract stable take-home pay. The remainder is the gap side income would need to cover, if that is your goal.
Use net figures, not gross app payouts. A $1,200 gig month might be $800 after gas and a tax reserve.
Turn the gap into hours
Divide the gap by your realistic net hourly rate from a calculator. That is how many hours the hustle must produce at your current efficiency. If the hours do not exist, the goal or the rate has to change.
This is an estimate, not advice
Every result here is a rough model based only on the numbers you enter. Sidequity is an informational tool and does not provide professional, tax, legal, investment, or financial advice, and it makes no income guarantees. Any tax set-aside is a planning placeholder, not a tax calculation.
For decisions that affect your money, taxes, or business, review your situation with a qualified professional. See our full disclaimer.
