Big Ambitions Profit Calculator
Calculate operating profit, margin and break-even from the numbers in your own business. Test one financial change and calculate contribution per unit without assuming demand or sales.

Use values from the same period.

These labels do not change the arithmetic. They help identify the scenario and can be carried into other tools.
Where does the money go?
Revenue, each entered cost, then operating profit. A large cost is not automatically a bad cost; check whether it produces enough value before cutting it.

Breakdown of entered costs only
Revenue, each entered cost, then operating profit. A missing cost is shown as a gap, not as zero.
Test one financial change
This is arithmetic what-if. Revenue is held constant unless you explicitly test revenue; demand, staffing and customer behavior are not predicted.
Optional
Unit economics
Calculate contribution per unit and the units needed to cover the fixed operating costs entered for the period. Optionally compare actual units sold with unit break-even.

Period operating costs treated as fixed: payroll, rent, marketing, licensing, theft/losses and other recurring costs. The variable product cost per unit is already inside contribution.
Unit break-even = fixed operating costs entered for the period ÷ contribution per unit. The variable product cost per unit is already inside contribution, so the period product-cost total is not added again. Units sold and customer response are not assumed.

Revenue is not profit. Operating profit subtracts the product or resource costs, payroll, rent, marketing, licensing and theft or losses that you enter. A blank field remains unknown; entering zero confirms that the cost does not apply.
Revenue break-even shows the revenue needed to cover the operating costs entered for the same period. Unit break-even divides those fixed operating costs by contribution per unit (selling price minus variable product cost per unit). It does not predict whether customers keep buying after a price change.
Use the Profit Guide when you need to diagnose why a margin is weak. Use the full Simulator when price, demand, staffing, capacity or marketing may change customer behavior and sales.
What is the difference between revenue break-even and unit break-even?
Revenue break-even is the revenue needed to cover the operating costs you entered. Unit break-even is the number of units you need to sell to cover those fixed costs at your contribution per unit. They answer different questions.
What if I do not know one of my costs?
Leave it blank. The page shows a known operating result and keeps final profit incomplete until required costs are entered or explicitly confirmed as zero.
Is operating profit the same as cash?
No. This calculator covers entered operating revenue and costs. Loans, financing movements, taxes and other non-operating cash changes are not mixed into operating profit.
Does increasing price always increase profit?
No. This calculator can show the arithmetic effect if unit sales stay unchanged. The Simulator is needed for demand and purchase-response effects.
Should payroll and marketing be included?
Yes, when they apply to the period being calculated. They are operating costs and affect profit and break-even.
