18 · Unit Economics, Pricing & Cashflow

Week 19 · 25 hours

Objective

Build a working financial model of your business, know your break-even, and set a price you can defend with arithmetic rather than feeling.

Why it matters commercially

Most small brands fail not because the product was bad but because the cash ran out at the wrong moment. Footwear has a particularly hostile cash cycle: you pay for everything months before you’re paid for anything.

Core concepts

The cash cycle, which is the real problem

  Month 0   ── Development charge + samples          −$1,500
  Month 3   ── 30% deposit on bulk order             −$2,400
  Month 5   ── 70% balance + inspection              −$5,900
  Month 5   ── Freight + duty + broker               −$1,400
  Month 5   ── Packaging, photography, site           −$1,200
            ───────────────────────────────────────────────
            CUMULATIVE OUT BEFORE FIRST SALE        −$12,400
  Month 6   ── Launch. Sell 120 of 250 pairs         +$16,800
  Month 9   ── Sell the next 80                      +$11,200
  Month 14  ── Sell the last 50 (discounted)         +$5,250

Two lessons jump out. First, the peak cash requirement comes before any revenue — which is exactly what pre-orders exist to solve (Module 19). Second, the tail is long: the last 20% of your run takes as long to sell as the first 80%, and usually at a discount. Model that honestly.

Unit economics

Per pair:

Line Example
Retail price (DTC) $140.00
− Payment processing (~2.9% + $0.30) −$4.36
− Landed cost −$41.75
− Outbound shipping (if free to customer) −$9.00
− Packaging & inserts −$1.50
− Returns provision (see below) −$7.00
= Contribution margin $76.39 (55%)

Then fixed costs — site, insurance, software, your own time if you’re paying yourself — divided by contribution margin gives your break-even units.

The returns provision

Footwear DTC returns run 15–30%, driven mostly by fit. Each return costs you return shipping, inspection, repackaging, and sometimes the unit if it comes back unsellable. Provision realistically: at a 20% return rate with $12 of cost per return, that’s $2.40 per pair sold plus the working capital tied up.

Reducing returns is a margin strategy, and it’s why Module 3’s fit work and Module 14’s wear testing matter financially, not just aesthetically. Concretely: publish a real size guide with foot-length-in-mm measurements, be explicit about fit (“runs half a size small”), and photograph the shoe on multiple foot shapes.

Pricing

Three inputs, in this order of authority:

  1. Cost floor. Below roughly 3× landed you cannot fund a second run. This is arithmetic, not opinion.
  2. Positioning. What does the customer compare you to? A minimal leather sneaker from an unknown brand competes at $120–180. A vulcanized canvas shoe competes at $70–110 and that’s a hard place to make money. This is a design decision as much as a pricing one — and it’s a reason to lean toward a construction and material story that supports a higher price.
  3. Willingness to pay. Test it in Module 19 with actual money, not surveys.

Practical notes:

  • Do not launch cheap intending to raise later. Raising prices on early customers is far harder than starting at the right number.
  • Price whole, e.g. $140 rather than $139.99, for a brand at this positioning.
  • Free shipping is close to an expectation in DTC. Build it into the price rather than adding it at checkout, where it kills conversion.
  • Avoid discounting the first drop. It permanently reframes your price. If you must move the tail, do it as a private sale to your email list, or as a sample sale, not as a public markdown.

If you ever wholesale

A retailer buys at wholesale (~50% of retail) and needs their own margin. So your $140 shoe wholesales at ~$65–70, against a $42 landed cost — a $25 margin instead of $76. Wholesale is a volume and credibility play, not a margin play, and it comes with payment terms (net 30–60) that worsen your cash cycle. Module 22 covers when it’s worth it.

The model you’re building

A single spreadsheet with these tabs:

  1. BOM & cost sheet — from Module 13
  2. Landed cost — from Module 16
  3. Unit economics — per-pair P&L at three price points
  4. Sales forecast — units by month, with the long tail modelled honestly
  5. Cashflow — weekly, 18 months, showing your lowest cash point
  6. Break-even — units and revenue
  7. Scenarios — pessimistic / base / optimistic, where pessimistic means selling 50% of the run in year one

The number that matters most is the lowest point on the cashflow tab. That’s how much money you actually need to have.

Do this

1 · Build the model (12h). All seven tabs. Real numbers where you have them, clearly flagged assumptions where you don’t.

2 · Three price points (3h). Model $110, $140, $170. For each: contribution margin, break-even units, and what proportion of your run you must sell to recover cash. Write a paragraph on which you’d choose and why.

3 · Pessimistic scenario (3h). Assume you sell 50% of the run in year one, returns run 25%, and freight costs 30% more than quoted. Does the business survive? If not, reduce the order quantity now.

4 · Competitive pricing map (3h). Twenty comparable shoes, their prices, their construction, their materials, their country of manufacture, their brand age. Place yourself on it honestly.

5 · Break-even memo (2h). One page: how many pairs must you sell to get your money back, by when, and what you’ll do if you don’t.

6 · Bookkeeping setup (2h). Get actual accounting software running and enter every expense to date from your build log.

Deliverable. A complete seven-tab financial model; a three-price-point analysis with a decision; a survivable pessimistic scenario (or a reduced order quantity); a competitive pricing map; a one-page break-even memo.

Self-check

  • Why does peak cash need come before any revenue?
  • What’s a realistic DTC footwear return rate and what does each return cost?
  • What’s the minimum multiple of landed cost you should price at, and why?
  • Why is wholesale not a margin strategy?
  • Which single number in your model matters most?

Traps

Optimistic sell-through. Assume the tail. Everybody sells the first 30% to friends, followers and early believers; the remaining 70% is the actual business.

Forgetting your own time. If you never pay yourself, the model isn’t real. Put a number in, even a small one.

Ignoring returns. At 25% returns your contribution margin can drop by a third. Model it.

Pricing from the cost up only. Cost sets the floor. Positioning sets the price.
