Calculate, benchmark, and improve profit margins across your business
A 50% markup on an $8.00 cost yields a 33% margin, not 50% — the single most expensive arithmetic error in small-business pricing. This guide gives the formulas for cost-plus, value-based, and penetration pricing, worked examples, the markup-vs-margin correction, and how to A/B test a price before committing.
Residential duct cleaning runs roughly $25–$50 per supply vent (about $75 for returns) and dryer vent add-ons average $145, so a one-line invoice hides your margin. This guide itemizes base fees, vent counts and add-ons, costs the four buckets behind each job, capitalizes a $9,000 vacuum rig instead of expensing it as supplies, and tracks the five KPIs — revenue per vent, revenue per tech-hour, upsell attach rate, callback rate, revenue per truck per day — that decide whether the next rig pays for itself.
How to keep the books for a gas station with a convenience store — splitting fuel from inside sales, tracking tank inventory in gallons, booking lottery as an agency arrangement, recording tobacco buydowns, and keeping card fees off the revenue line. U.S. convenience stores rang up a record $341 billion of in-store sales in 2025, yet NACS found the average in-store basket lost roughly seven cents per transaction after expenses.
Pour cost is beverage COGS divided by beverage revenue — target 15-20% on spirits, 20-25% on draft, and 25-35% on wine by the glass. This guide covers how to compute usage and variance weekly, why a half-barrel keg yields about 112 pints instead of the theoretical 124, and how to split revenue, COGS, comps, and keg deposits so the leak is visible in the ledger.
Filament is often under a third of a 3D print's true cost. A six-layer costing method — filament, electricity, wear parts, failed prints, post-processing labor, and machine depreciation — shows why a $4.20 print really costs $15.32, and how to work backwards from Etsy's ~10–12% fees to a list price with a real margin.
Surveys put 64% of diners against restaurant surge pricing and 81% ready to avoid peak hours or leave entirely, while 75% will shift to an off-peak visit for an incentive — so discount the trough instead of taxing the peak, and track discounts, daypart P&L and delivery fees as separate lines.
Ghost tour and walking-tour operators often keep less than half of ticket revenue after OTA commissions of 20–30%, guide pay, and year-round insurance. Here is how to book per-seat contribution margin by channel, treat advance sales as deferred revenue, and budget October to fund February.
How elevator service companies job-cost full-maintenance and exam-and-lube contracts per unit — booking prepayments as deferred revenue, costing callbacks at a burdened CET mechanic rate of 85 to 100 dollars an hour rather than the 52-dollar wage, carrying truck stock as inventory, and pricing renewals from twelve months of callback history.
Zone skipping loads all parcels bound for one region onto a single truck and hands them to the carrier near the customer, repricing a Zone 7–8 cross-country label as bulk freight plus a Zone 2 final leg — a 20–40% cut on that leg and roughly $5,000 off a $30,000 week for 3,000 New York–to–California packages. It only pays above about 1,000–1,500 parcels a week to one region and adds about one transit day; this guide covers the break-even math, the mistakes that erase the savings, cheaper alternatives like split inventory and rate shopping, and how to book linehaul freight, consolidator fees and final-leg postage so the program's margin is actually measurable.
Ground beef hit about $6.75 a pound and steak $12.80 in May 2026, with the U.S. cattle herd at a 75-year low of 86.2 million head and relief unlikely before 2028. This guide shows restaurants and butcher shops how to recost every beef item, spread increases across the menu, move down the carcass, and track item-level margin after the change.
How a screen-printing shop tracks blank garments and ink as job-level inventory, prices each additional color as a production change rather than extra ink, and sets a rework reserve from actual misprint history — plus a weekly close routine that ties deposits, job costs, and margins together.
A feed store guide to costing bulk feed and bagged SKUs at delivered cost—allocating inbound freight, choosing FIFO or weighted average, counting bulk bins to expose shrink, and reconciling the inventory subledger monthly.
