Side Hustle Income Goal Calculator

See how many sales per day you need to reach a monthly income goal.

Why break a goal into daily sales?

"$1,000 a month" sounds big and vague. "11 sales a day" is a number you can track, test and improve. Breaking a monthly goal down to sales per day, and then per product, shows you very quickly whether a plan is realistic. It also tells you which lever matters most: raising profit per sale, adding more products, or getting each product to sell more often.

The formula

Sales per month = (monthly profit goal + monthly fixed costs) ÷ profit per sale
Sales per day = sales per month ÷ 30.4 (average days in a month)
Sales per product per day = sales per day ÷ number of products

Worked example

You sell printed books that earn about $3 profit each and want $1,000 a month. That is $1,000 ÷ $3 ≈ 334 sales a month, or about 11 a day. With 30 books in your catalog, each book needs to sell only about 0.37 copies a day — roughly one sale every three days. With just 3 books, each would need almost 4 sales a day, which is much harder. This is why many sellers focus on building a catalog instead of relying on one product.

How to use the results

• If sales per product per day is under 1, the goal is often reachable by adding more products over time.
• If it is well above 1, look at raising your price, cutting costs, or adding products before spending more on ads.
• Include fixed costs. Paid ads and tools come out of your profit, so they raise the number of sales you need.
