The Chicken-and-Egg Problem is Hard. Modeling It Shouldn’t Be.

Building a two-sided marketplace—whether it’s connecting freelancers, drivers, or B2B buyers and sellers—is a balancing act. You have to acquire two completely different user groups simultaneously, often at a loss, just to build enough liquidity to make the platform useful.

Trying to model this in Excel usually results in a tangled web of tabs. How do you separate the Customer Acquisition Cost (CAC) for supply versus demand? How do you model the lag between when a supplier signs up and when they actually generate Gross Merchandise Value (GMV)? One wrong assumption about your take rate or churn can make your marketplace look like a goldmine or a black hole.

It’s time to ditch the generic spreadsheets and use a dynamic financial model built specifically for the unique mechanics of two-sided platforms.

What Makes This the Ultimate Marketplace Unit Economics Tool?

Built for marketplace founders, operators, and venture capitalists who need to understand the true health of a platform.

• Split Supply & Demand Modeling: Independently track user growth, churn, and acquisition costs for both sides of your platform. See exactly how supply constraints or demand drops impact your overall GMV.
• Dynamic Take Rate & Revenue Engine: Model tiered commission structures, subscription fees, and payment processing fees. Instantly see how a 1% increase in your take rate impacts your bottom line over 3 to 5 years.
• Cohort-Based Liquidity Tracking: Visualize the “marketplace liquidity flywheel.” See how long it takes for a new user cohort to become active and transacting, and how that accelerates as your network grows.
• Instant Unit Economics (CAC/LTV): Automatically calculates blended and segmented Customer Acquisition Cost, Lifetime Value, and LTV:CAC ratio for both buyers and sellers.
• One-Click Investor Deck Export: Raising a Series A? Export a perfectly formatted, professional PDF summary of your marketplace metrics, GMV projections, and pathway to profitability to share with partners.

How It Works

1. Define Your Sides: Input the baseline metrics for your Supply (e.g., drivers, sellers) and Demand (e.g., riders, buyers).
2. Set the Economics: Enter your average order value, transaction take rate, payment processing costs, and marketing spend.
3. Simulate & Scale: View your automated 5-year projections for GMV, Net Revenue, EBITDA, and cash burn to make informed growth decisions.

Frequently Asked Questions

Does this work for service marketplaces (like Upwork) as well as product marketplaces (like Etsy)?

Yes. Because you define the “Average Transaction Value” and “Take Rate” yourself, the model is completely agnostic. It works for B2B SaaS marketplaces, freelance platforms, delivery apps, and traditional e-commerce marketplaces.

Can I model different payment processing fees?

Absolutely. There is a specific input for payment gateway fees (e.g., Stripe, PayPal). You can set it as a flat percentage of GMV to see exactly how much revenue you lose to payment processors before calculating your net take rate.

Does it calculate the “Marketplace Liquidity” metric?

Yes, it models the core drivers of liquidity. By tracking the ratio of active supply to active demand over time, you can visually see on the charts when your platform crosses the threshold from a “cold start” to a functioning, liquid marketplace.

Is my startup’s data secure?

Absolutely. This is a standalone HTML application. It does not send, store, or transmit your sensitive unit economics or user data to any external server. Your competitive advantage stays entirely on your local machine.
