About this model
By Rotation is a peer-to-peer fashion-rental marketplace where members list, rent, and resell designer items through an app. The inventory remains with lenders, giving the platform a circular-fashion proposition without the inventory risk of a traditional rental operator.
The research records more than 250,000 active app users, 20,000 listed designer items, and a highly engaged audience. Revenue comes from commission on rentals and resale transactions, with partnerships and community events providing additional but less certain commercial opportunities.
The financial model builds GMV from active lenders, listings, rental frequency, daily price, and rental duration. A marketplace take rate produces net revenue, while resale is modeled as a second transaction stream. Payment processing, trust and safety, marketing, and lender liquidity determine contribution margin and the pace of marketplace growth.
A turnkey financial model
Live formulas, no hardcoded values
Outputs are driven by live formulas, so the workbook updates from its assumptions instead of relying on hardcoded results.
All assumptions in one tab
Inputs are clearly marked in the Assumptions tab and separated from calculations, making it clear what to change and what to leave intact.
Statements always balancing
For integrated-statement models, the balance sheet, cash flow, and supporting schedules tie through properly.
Distinct schedules for clarity
Debt, working capital, taxes, and cash flow can get messy quickly. We group calculations in clear schedules, not across disconnected tabs.
No hidden macros or external links
There are no unexplained external workbook links or macros to undermine auditability or portability.
Changes flow through the model
Update a key driver and see the impact carry through the forecast, financing, and return outputs. We never use hardcoded numbers in formulas.

Recommended financial model
- Archetype + why: P2P marketplace GMV model. Revenue is derived as (GMV × take rate); GMV is the primary driver, built bottom-up from active lenders × avg. listings per lender × rental frequency × avg. daily rate × avg. rental duration. Resale GMV is a secondary stream. Fits standard marketplace mechanics; no inventory, so gross margin structure is simple (net revenue after payment processing).
- Forecast horizon & granularity: 3 years monthly (Year 1–2 monthly, Year 3 can collapse to quarterly); early-stage with limited disclosed financials warrants monthly for cash burn visibility.
- Key drivers & assumptions:
| Driver | Value / Source |
|---|---|
| Active app users (base) | 250,000 |
| % actively renting (utilisation) | 85% |
| Active renters (base) | ~212,500 |
| Avg. rental transactions per active renter per month | 0.5–1.0; fashion rental is occasion-driven, not weekly |
| Avg. rental value (ARV) | £40–£60/transaction; proxy from £10/day × 3-day min with expected average above minimum |
| Platform take rate (rental) | 15–20%; benchmark against Fat Llama, Hurr Collective (15–17%) |
| Platform take rate (resale) | 10–15%; lower than rental, more commoditised |
| Resale GMV as % of rental GMV | 10–15%; secondary channel per deck positioning |
| Active user growth (MoM) | 3–5% early months, decelerating to 1–2% by Year 3 |
| Listings (base) | 20,000+ |
| Avg. daily rental rate | £10–£20 (£10/day shown as example floor) |
| Payment processing cost | 2.5–3% of GMV (Stripe/standard) |
| CAC | £5–£15 (social/community-led; heavy organic/press-driven) |
| Gross margin (net revenue – processing) | ~80–85% after payment costs |
| Headcount cost | 4 FTEs currently; model should include hiring plan for sales/ops |
| Community events / pop-up cost | line-item required; not quantified in deck |
- Scenarios (Base / Bull / Bear - which variables flex):
- Base: Active user growth at 2.5% MoM, take rate 17%, ARV £50, 0.7 transactions/renter/month.
- Bull: Faster user growth (4% MoM), geographic expansion to US/EU, B2B partnership revenue materialises.
- Bear: User growth stalls at 1% MoM (market saturation / competitive entry), take rate pressure to 12%, lower rental frequency (0.4 tx/renter/month).
- Required sheets / outputs:
- Assumptions dashboard (all toggleable drivers)
- GMV build (renters × frequency × ARV, split rental vs. resale)
- Revenue & gross profit (GMV × take rate, less payment processing)
- Headcount & operating expense plan
- P&L summary (monthly, Year 1–3)
- Cash flow & runway (critical: burn rate vs. undisclosed raise)
- KPI summary (active users, GMV, net revenue, take rate, transactions)

Hey, I’m Alex and I created Finamodel.
Over my years in the finance industry I kept building the same models over and over again. Same structure, same assumptions, different logo. So I started building frameworks to turn them into clean, reusable templates.
Every model here is one I’d actually use for a client, and I personally vet each one before it goes up.
I’m not an expert in every industry, but I’ve built enough models to know what belongs in one. And when something is completely foreign to me, I reach out to my network for experts to work on our models with us.
Having a template library on hand cuts a first build from hours to minutes.
Need help finding your model? You’ll find me in the Finamodel app!
