The business calculator hub combines focused tools for gross profit,
gross margin, markup, break-even sales and target profit. Each
calculator uses transparent formulas and keeps the inputs visible, so
the result can be checked against the company’s accounting records.
Quick gross-profit check / Snelle brutowinstcontrole
Quick break-even check / Snelle break-evencontrole
Use one definition consistently / Gebruik één definitie consequent
Gross margin, markup and contribution margin answer different questions. Match revenue and cost to the same period and document whether an expense is direct, variable or fixed. These calculators do not provide a formal valuation, tax return or cash-flow forecast.
Brutomarge, opslag en dekkingsbijdrage beantwoorden verschillende vragen. Laat omzet en kosten op dezelfde periode aansluiten en leg vast of een post direct, variabel of vast is. Deze calculators maken geen formele waardering, aangifte of kasstroomprognose.
Gross profit calculator
Use net sales revenue and the matching cost of goods sold. The result
is gross profit, gross margin and markup.
Gross profit = revenue − cost of goods sold
Gross margin = gross profit ÷ revenue
Markup = gross profit ÷ cost of goods sold
Margin uses sales as its base; markup uses cost. A $100 sale with $60
cost produces $40 gross profit, a 40% gross margin and a 66.67%
markup.
Pricing calculator
Use the pricing tool when cost and target gross margin are known. The
core formula is:
Price = unit cost ÷ (1 − target gross margin)
If unit cost is $45 and target margin is 25%, the calculated price is
$60. This is a mathematical price, not proof that customers will accept
it. Add applicable taxes, channel fees, expected discounts and minimum
order economics in the commercial decision.
Break-even calculator
Enter fixed costs, selling price and variable cost per unit. The tool
calculates contribution margin and the units required to cover fixed
costs.
Break-even units = fixed costs ÷ (price − variable cost per
unit)
The formula requires a positive contribution per unit. If variable
cost equals or exceeds price, selling more does not cover fixed costs
under the model. Adjust the economics rather than treating the displayed
warning as a software error.
Target-profit calculator
Break-even produces zero operating profit. To plan a specific result,
add target profit to fixed costs:
Required units = (fixed costs + target profit) ÷ contribution
margin per unit
Use operating profit consistently. Financing costs, tax, startup
investment and owner distributions may need separate treatment. Round
physical units up and test whether capacity can deliver the required
volume.
Can a
calculator value a business with $1 million in sales?
Revenue alone cannot produce a defensible business valuation. Two
companies with $1 million of sales can differ in margin, recurring
revenue, growth, customer concentration, assets, debt, owner dependence
and risk.
Valuation methods may use normalized earnings, discounted cash flow,
assets or comparable transactions. Each requires assumptions beyond
annual sales. A simple revenue multiple can be a rough scenario only
when supported by relevant market evidence and adjustments. Obtain
qualified valuation advice for a sale, tax, dispute or financing
decision.
Which numbers should you
enter?
Use figures from the same period, entity and currency. Remove sales
tax collected for an authority from revenue. Match cost of goods sold to
the sales reported. Split mixed costs when possible and document
allocations.
For planning, use expected values plus a lower and higher scenario.
Supplier pricing, returns, discounts and payment fees can change the
result materially. Keep a dated copy of assumptions rather than updating
a result without an audit trail.
How do the calculators
connect to the P&L?
Gross profit should reconcile with revenue and cost of goods sold on
the profit and loss statement. Break-even uses the same contribution
economics but separates variable and fixed cost behavior, which may not
match the P&L’s presentation line for line.
Investigate differences. An expense can be classified below gross
profit on the P&L yet still behave as a variable cost for a decision
model. The classification must fit the question and remain clearly
documented.
What the tools do not
calculate
The hub does not create a full tax return, cash-flow forecast, loan
decision or formal valuation. Results are estimates based on entered
data. Use accounting records for historical reporting and test model
assumptions before changing prices, staffing or capacity.
Choose the smallest calculator that answers the question. A focused
formula is easier to verify than one large output that combines
incompatible assumptions.
