Pricing & margins methodology

1. Overview

The pricing-and-margins category covers the calculators an operator opens before quoting a client, raising prices, or hiring a first employee on a retainer book: gross margin and retainer-to-hourly-rate conversion. The math here is basic managerial accounting; the work this category does is forcing operators to look at margin and markup as two different numbers, and to convert retainer scope into a true hourly rate they can defend in a renegotiation.

2. Primary sources

• FASB ASC 606 — Revenue from Contracts with Customers. The accounting-standard governing what counts as revenue and when. Important for COGS classification on the gross-margin calculator: ASC 606 defines transaction price, variable consideration, and the cost basis that flows through to gross-margin reporting. asc.fasb.org/topic/606
• Garrison / Noreen / Brewer, Managerial Accounting (16th edition). The standard reference for break-even, contribution margin, and margin-vs-markup definitions. The textbook treatment is direct and unambiguous: margin uses revenue as the denominator; markup uses cost.
• Aswath Damodaran, NYU Stern industry margin dataset. Source for industry-comparison gross-margin benchmarks. Updated annually on the New York University Stern site. pages.stern.nyu.edu
• U.S. Bureau of Labor Statistics, Occupational Employment and Wage Statistics (OEWS). Source for occupation-specific median hourly wages used to sanity-check retainer pricing inputs. bls.gov/oes

3. Formula derivations

Gross margin and markup. The two are not the same number. Gross profit = revenue − COGS. Margin and markup differ only in what's in the denominator:

Gross Margin % = Gross Profit ÷ Revenue
Markup % = Gross Profit ÷ COGS

A 50% margin equals a 100% markup. A 25% margin equals a 33.33% markup. The single most common pricing error in small business is confusing the two — a contractor charging 30% markup believing it's 30% margin is actually running at a 23% margin and wondering why the year-end numbers don't tie out. The calculator surfaces both explicitly and never lets the page show one without the other.

Reverse mode (target margin → required price). Given target margin M (decimal) and per-unit cost C, required price = C ÷ (1 − M). This is the right operator framing for "I want to hit 40% gross margin — what do I need to charge?" rather than the (wrong) intuitive temptation to add 40% on top of cost.

Retainer-to-hourly conversion. True hourly rate = monthly retainer ÷ monthly hours actually delivered. The calculator forces operators to enter both the contracted scope hours and the realistic delivered hours (typically meaningfully higher because of meetings, scope creep, and async overhead). The output is the rate the engagement is actually paying, which is usually 30-50% lower than the rate the contract appears to imply.

A retainer is profitable if the true hourly rate exceeds the fully-loaded cost rate of the operator delivering it. Fully-loaded cost rate = (annual base salary + benefits load + overhead allocation) ÷ billable hours per year. The calculator surfaces the gap as an absolute dollar figure rather than as a single profitability boolean.

4. Edge cases and assumptions

• COGS classification. The line between COGS and operating expense varies by accounting policy. Software companies often debate whether hosting, customer support, and dev-ops belong in COGS or G&A. The calculator does not enforce a single classification — it computes margin and markup from the COGS the operator enters. ASC 606 provides guardrails but not a single right answer.
• Variable consideration. For revenue with refund clauses, returns reserves, or volume rebates, ASC 606 requires booking the expected variable consideration rather than face value. The calculator assumes the revenue input is already adjusted; if the operator enters gross invoice value, the resulting margin overstates.
• Service-business COGS. For pure service businesses, COGS often equals labor cost only, with overhead in operating expense. The retainer calculator handles this by separating direct labor from overhead allocation.
• Multi-product mix. The calculator computes blended margin from total revenue and total COGS. Operators with materially different per-product margins should run the calc per product line, not blended, to catch the case where a low-margin product is masking a healthy high-margin one.

5. Update protocol

Pricing-and-margins calculators are reviewed quarterly and updated on these triggers:

• FASB issues an ASC 606 amendment or new revenue-recognition Accounting Standards Update (ASU).
• Damodaran publishes the annual industry-margin dataset refresh.
• BLS OEWS publishes the May vintage of national wage data.

Material errors are documented on the corrections page.

6. Limitations

These calculators are estimates for educational use. They do not replace a CPA's review of revenue recognition policy, a pricing consultant's market study, or counsel on enforceable contract terms. Industry margin benchmarks are population averages — your margin should reflect your specific positioning, cost structure, and pricing power, not converge on a category mean.
