What is Price-Volume-Mix analysis?
Price-Volume-Mix (PVM) analysis, also called Volume / Rate / Mix analysis, explains why a total changed between two periods by splitting the variance into three additive drivers: a volume effect (selling more or fewer units), a rate effect (a different price or cost per unit), and a mix effect (a shift in the blend of what was sold). The three always sum to the total change.
Is Volume / Rate / Mix the same as Price / Volume / Mix?
Yes, the same decomposition. "Rate" is the general term for the per-unit driver: a price for revenue, a unit cost for cost, ARPU for subscriptions, or average compensation for headcount. "Volume" is the general term for the quantity. Using rate and volume lets the method work across all of these.
What is the mix effect?
The change caused by selling a different proportion of high-rate versus low-rate items, even when total volume and each item's rate stay the same. Shifting the blend toward pricier items raises the average value per unit, and that uplift is the mix effect. More on mix →
How do you calculate the volume, rate, and mix effects?
Per item: Rate = (New Rate − Base Rate) × New Volume; Volume = (Total New Volume − Total Base Volume) × Base Rate × Base Share; Mix = Total Variance − Rate − Volume. See the fully worked example.
Is my data uploaded to a server?
No. Everything runs in your browser with an in-browser SQL engine (DuckDB WASM). Your data never leaves your computer and is never stored on a server.
Is it free to use?
Yes, it's currently free. Sign in with your email and a one-time code, no password required.
Can I analyze cost or headcount, not just revenue?
Yes. Any metric that's quantity × rate works: revenue, cost, personnel cost, and subscriptions all have built-in presets.
What file formats can I upload?
CSV and Excel files, or start from a built-in demo dataset.
