Financial Modeling Examples

A financial model looks different for every business model. Here are three concrete examples — SaaS, ecommerce, and marketplace — showing how the structure adapts to the economics of the company.

Example 1 — SaaS Financial Model

A B2B SaaS company with three pricing tiers (Starter, Professional, Enterprise) and an inside sales team. The model must capture recurring revenue dynamics, churn at the logo and revenue level, and the efficiency of the sales organisation.

Key Components

  • New customer acquisition: Number of new customers per month per tier, driven by sales headcount and productivity (demos per rep, conversion rate). Sales ramp time is factored in.
  • Recurring revenue: Monthly recurring revenue (MRR) build — beginning MRR + new MRR + expansion MRR − churned MRR = ending MRR. Annual recurring revenue (ARR) is the annualised MRR run rate.
  • Churn: Logo churn rate (percentage of customers lost per month) and revenue churn rate (including downgrades). Churn assumptions are tier‑specific — Enterprise churns less than Starter.
  • Expansion revenue: Upgrades from lower tiers to higher tiers, modelled as a percentage of existing customers moving up each period, with the associated ARPU change.
  • Customer acquisition cost (CAC): Total sales and marketing spend divided by new customers acquired in a period. Blended CAC and payback period are calculated.
  • LTV/CAC ratio: Lifetime value (gross margin per customer divided by churn rate) compared to CAC. A ratio above 3x is expected for a healthy SaaS business.
  • Three‑statement output: Integrated P&L, balance sheet (deferred revenue is critical in SaaS), and cash flow statement. Cash flow shows the impact of annual prepayments if offered.

Example 2 — Ecommerce Financial Model

A direct‑to‑consumer brand selling physical products through its own website. The model must handle inventory, working capital, and unit‑level contribution margins.

Key Components

  • Traffic and conversion: Website sessions (driven by marketing spend and organic growth) × conversion rate = orders. Average order value (AOV) is modelled separately, with assumptions about seasonal variation.
  • Cost of goods sold (COGS): Product cost per unit, shipping cost, payment processing fees. COGS is modelled per unit and linked to order volume, with volume discounts at scale.
  • Inventory management: Inventory purchases are modelled on a reorder cycle with lead times. The balance sheet holds inventory, and the cash flow statement shows cash outflows for inventory before it is sold.
  • Marketing spend: Paid channels (Google, social, affiliate) with cost‑per‑click, conversion rate, and spend budget. Marketing efficiency is measured by return on ad spend (ROAS).
  • Contribution margin: Revenue minus COGS and direct selling costs (payment processing, shipping). Contribution margin per order must be positive before accounting for fixed overheads.
  • Working capital: Accounts payable (payment terms with suppliers), accounts receivable (if any B2B sales), and inventory turnover. These directly affect cash flow.

Example 3 — Marketplace Financial Model

A peer‑to‑peer services marketplace connecting freelancers with clients. The model must capture both sides of the platform — supply acquisition and demand generation — and the liquidity dynamics between them.

Key Components

  • Gross merchandise volume (GMV): Number of transactions × average transaction value. Transactions are driven by demand‑side marketing and supply‑side availability.
  • Take rate: The percentage of GMV the platform retains as revenue. Take rate may vary by service category or scale (enterprise clients negotiate lower rates).
  • Supply‑side acquisition: Number of active freelancers, driven by onboarding campaigns and retention. A churn model for freelancers is essential — if supply drops, transactions drop.
  • Demand‑side acquisition: Customer acquisition spend, conversion from visitor to booking, repeat booking rate. Marketplace liquidity — the ability to match supply and demand quickly — is a key metric.
  • Contribution margin per transaction: Revenue minus direct costs per transaction (payment processing, insurance, customer support). Contribution margin covers platform overheads.
  • Expansion into new categories or geographies: Modelled as a separate scenario with its own supply/demand assumptions, launch costs, and ramp‑up period.
