To understand your EBITDA miss, you'll want to analyze the variance between budget and actuals across your key line items.

Start by comparing:
- Revenue vs. budget
- Cost of goods sold
- Operating expenses (payroll, marketing, G&A)

For each line, calculate the variance and identify which had the biggest impact. Revenue misses often come from lower volume or pricing, while expense overruns can come from unplanned hires or one-time costs.

Once you know where the variance is concentrated, you can dig into the drivers.

EBITDA BRIDGE — Q3 Budget vs Actual
Materiality filter: variances over $25K or 5% shown; rest rolled to Other.

  Budget EBITDA .......................... $1,840K
  ───────────────────────────────────────────────
  Revenue — volume        −$310K  ← the story is here
  Revenue — price         +$140K
  Revenue — mix           − $60K
  COGS — volume-driven    +$180K   (flows with the volume miss)
  Payroll — headcount     −$220K
  Payroll — timing        + $90K
  Marketing               − $70K
  Other (below threshold) − $30K
  ───────────────────────────────────────────────
  Actual EBITDA .......................... $1,600K   miss: $240K

WHAT THE DECOMPOSITION SAYS THAT THE TOTAL HIDES
The $240K miss is NOT a spending problem. It's a volume problem partly
masked by good pricing.

  Revenue: you lost $310K on volume but clawed $140K back on price —
  you held or raised prices into a soft quarter. Net revenue driver
  is −$230K, and it's demand, not discounting.

  Payroll: −$220K headcount looks like an overrun, but +$90K of timing
  says planned hires landed early, not that you overspent on comp. Net
  −$130K, and it's a phasing issue that reverses.

  COGS +$180K is favorable and mechanical — you sold less, so you spent
  less to make it. Not a win, just the other side of the volume miss.

THE ONE SENTENCE FOR THE BOARD
"We missed by $240K driven almost entirely by lower volume ($230K net
of a favorable pricing offset); the payroll variance is early hiring
timing that normalizes in Q4, not a structural cost overrun."

WHERE TO LOOK NEXT
The volume miss. Price held, so this isn't a competitiveness problem —
it's pipeline or seasonality. Pull the volume variance by product line
and I'll tell you if it's concentrated or broad.
