GMV

TL;DR

Gross Merchandise Value — the total dollar value of transactions processed through a marketplace or platform over a given period.

GMV is the headline volume metric for marketplaces and payment platforms. It captures what users transacted, not what the platform earned. Net revenue is GMV multiplied by take rate, minus payment processing and fulfillment costs.

GMV is useful for showing scale and growth; it is not, by itself, a measure of business health. A marketplace with $1B GMV at a 1% take rate is structurally weaker than one with $200M GMV at a 15% take rate. Investors discount GMV-only narratives.

Formula

GMV = Σ (Order Value × Order Count) over Period

• Order Value — Gross transaction value of each order before refunds, returns, and platform fees
• Order Count — Number of qualifying transactions in the period

GMV ≠ revenue. Net revenue is GMV × take rate, less returns and chargebacks.

Worked example

A marketplace processes 1.2M orders averaging $48 each in Q4 → GMV $57.6M. With a 15% take rate and 4% returns, net revenue ≈ $57.6M × 15% × 96% = $8.3M.

Common pitfalls

• Reporting GMV as if it were revenue.
• Including processed-but-refunded volume in GMV.
• Letting GMV growth mask declining take rate.

When this shows up in a pitch deck

Marketplaces show GMV alongside take rate, net revenue, and contribution margin — never alone.
