📌 About Business & Marketing

Running a business or a side hustle comes down to a handful of numbers: what to charge, what you keep, and when you start making money. These calculators turn cost and price into the metrics that actually drive decisions — profit margin and markup (and why they are not the same thing), the break-even point where a product starts to pay off, return on investment, the CPM behind an ad buy, and the hourly rate a freelancer needs to hit an income goal.

Each tool shows the formula and a worked example in US dollars, so the result is something you can act on, not just a number. Use them to price a product, set a sale, size up a marketing spend, or quote a client — and treat the outputs as planning estimates, not financial or tax advice.

  • Find gross profit margin and the markup needed to hit it (margin is of price, markup is of cost)
  • Calculate the break-even point in units and revenue
  • Measure ROI on a purchase, campaign or investment, with an annualized option
  • Work out CPM, CPC and CPA for an ad budget
  • Price a product or sale and work backward from a discounted price
  • Set a freelance or contractor hourly rate from your income goal

❓ Frequently asked questions

What's the difference between markup and margin?

Markup is profit as a percentage of cost; margin is profit as a percentage of the selling price. A 50% markup on a $60 cost is a $90 price, which is a 33% margin — the same dollars, two different bases.

How do I calculate my break-even point?

Divide your fixed costs by the contribution margin per unit (price minus variable cost). At $10,000 fixed costs, a $50 price and $30 variable cost, you break even at 500 units.

How is ROI calculated?

ROI is (final value minus cost) divided by cost, times 100. Putting in $1,000 and getting back $1,300 is a 30% ROI. For multi-year returns, an annualized figure tells you the yearly rate.

What hourly rate should I charge as a freelancer?

Add the salary you want, your business expenses and a profit cushion, then divide by your billable hours for the year. Remember self-employment tax comes out of that rate — the freelance rate calculator handles the math.
