Business & Pricing Calculators

The percentage change between two consecutive periods — the momentum metric behind analytics and KPI dashboards — with the absolute change alongside.

Find your gross margin from cost and price, or price a product to hit a target margin — with the markup, profit, and the margin-vs-markup distinction made clear.

Work out the markup on a product, or set a price from a target markup — and see why a markup is always a bigger number than the margin it produces.

Calculate gross profit margin from revenue and cost, see the dollar profit per unit, and price to a target margin — the number that protects your bottom line.

Convert between margin and markup and see both at once for any cost and price — so you never price off the wrong one and quietly lose profit.

Return on ad spend from revenue and ad cost — plus the full funnel (CPM, CPC, CTR, conversion rate, CPA, ROI) so you see what is really driving the number.

Cost per thousand impressions from spend and impressions — with CPC, CTR, conversion rate, CPA, ROAS, and ROI for the same campaign in one view.

Click-through rate from clicks and impressions — alongside the rest of the funnel so you can tell whether a high CTR is actually converting.

Your conversion rate from conversions and clicks — with cost per conversion, ROAS, and ROI so you know what each conversion costs and earns.

Your fully-loaded cost to acquire a customer — every sales and marketing dollar divided by the customers it won, the foundation of healthy unit economics.

Customer lifetime value from ARPU, margin, and churn — plus the LTV:CAC ratio and CAC payback period that reveal whether growth actually pays

The share of customers lost over a period, with its retention complement — the leak in the bucket that quietly compounds and sets the ceiling on lifetime value.

How many of the customers you started with are still here — new sign-ups stripped out, so growth can’t hide a leaky base. The quiet engine of compounding revenue.

The cost of a single conversion — lead, sign-up, or sale — at the campaign level, and how it differs from the fully-loaded CAC for a paying customer.

Break-even point — the units and revenue needed to cover costs, fixed costs divided by contribution margin per unit — the first number a business needs

The contribution margin per unit and its ratio — what each sale leaves toward fixed costs and profit after variable costs — the engine behind break-even and pricing.

Gross and net profit from revenue, cost of goods sold, and operating expenses — with the gross and net margins that show how much of each sales dollar you keep.

The order size that minimizes total inventory cost — balancing ordering against holding costs — plus how often to order and the annual cost at that quantity.

How long an investment takes to pay for itself — initial outlay divided by annual cash flow — the quick screen for whether a project recovers its cost soon enough.

All three textbook forms of customer lifetime value — simple, margin, and the discounted Gupta–Lehmann perpetuity — with the LTV:CAC ratio and CAC payback months.

Full depreciation schedules under straight-line, double-declining balance, sum-of-the-years-digits, and units of production — year by year, with book value tracked to salvage.

Gross burn, net burn, and months of runway — with a growth simulation that answers the default-alive question: does revenue reach break-even before the cash runs out?

Current, quick (acid-test), and cash ratios plus net working capital from a handful of balance-sheet lines — the three liquidity tests side by side with interpretation bands.

The fully-loaded annual cost of an employee — salary plus employer FICA, unemployment taxes, benefits, and overhead — with the cost multiplier and true cost per working or billable hour.
