Output Example

## Budget variance explanation — Marketing / March FY26

### Headline
Marketing spend **+12% vs budget** ($1.12M actual vs $1.00M plan).

### Drivers
1. **Events (+$85k):** two industry conferences moved into March from April.
2. **Paid search (+$42k):** CPC up ~11% on branded + category terms after competitor campaign.

### Mitigations already in motion
- Shift $60k from Q2 syndication budget to cover March events.
- SEM team running negative keyword audit weekly through April.

### Outlook
Expect April marketing spend to normalize unless CPC remains elevated — monitor weekly and revisit forecast in week 3.
