# Budget Planning

## Annual Budget Process

### Timeline (Reverse Calendar)
| Date | Milestone |
|------|-----------|
| Oct 1 | CFO issues budget guidelines and macro assumptions |
| Oct 15 | Department heads submit headcount plans |
| Oct 31 | Department heads submit expense budgets |
| Nov 15 | Finance consolidates, identifies gaps vs. plan |
| Nov 30 | Executive review and negotiation |
| Dec 15 | Board approval |
| Jan 1 | Budget locked — new fiscal year begins |

### Macro Assumptions to Align Early
- Revenue growth target (top-down or bottoms-up)
- Headcount growth % by function
- Inflation assumption for salary increases
- Capital markets / fundraising assumptions
- Key risk scenarios: bull / base / bear case

---

## Budget Approaches

### Top-Down
- Executive sets targets → departments fill in how to achieve
- Fast, aligned to strategic priorities
- Risk: unrealistic targets disconnected from operational reality

### Bottoms-Up
- Departments build from detailed plans → consolidate to company total
- More accurate, builds ownership
- Risk: empire building, everyone asks for more than needed

### Zero-Based Budgeting (ZBB)
Every line item must be justified from zero — prior year spend provides no entitlement.

**ZBB Process:**
1. List all activities performed by the team
2. For each activity: what is the output? What does it cost to deliver?
3. Rank activities by strategic value
4. Allocate budget from highest to lowest priority until budget cap is hit
5. Document what is cut and the business impact of each cut

**Best for:** Cost-heavy functions (G&A, marketing ops), post-acquisition cost rationalization

### Rolling Forecast
- Re-forecast full year every quarter (or monthly for fast-moving companies)
- Replace static annual budget with living projection
- Formula: Actuals YTD + updated forecast for remaining months

## Department Budget Template

```
Department: [Name]
Budget owner: [Name / Role]
Fiscal year: YYYY

HEADCOUNT
  Current HC:     N FTEs
  Planned hires:  +N FTEs (list by role + planned start date)
  Planned exits:  -N FTEs (attrition assumption)
  Year-end HC:    N FTEs

  Salary & benefits:     $X
  (loaded cost per employee: base + benefits + payroll tax ≈ 1.25× base)

DIRECT EXPENSES
  Software / SaaS:          $X
    [Tool 1]:               $X/year ([N] seats × $X/seat)
    [Tool 2]:               $X/year
  Contractors / agencies:   $X
  Travel & entertainment:   $X
  Training & development:   $X
  Conferences:              $X
  Other:                    $X

ALLOCATED EXPENSES (from shared services)
  IT:          $X
  Facilities:  $X
  HR:          $X

TOTAL DEPARTMENT OPEX:  $X

CAPEX (if applicable)
  [Equipment / infrastructure investment]:  $X
  Useful life: N years → annual depreciation: $X/year

TOTAL BUDGET: $X
YoY change vs. prior year: +/-X%
```

## Headcount Planning

### Headcount Model Inputs
| Input | Owner | Notes |
|-------|-------|-------|
| Revenue plan | Finance | Drives sales / CS HC |
| Product roadmap | Product | Drives engineering HC |
| Support volume forecast | Support | Drives support HC |
| Target ratios | Executive | e.g., 1 CSM per $Xm ARR |
| Backfills | HR | Track separately from growth hires |

### Function-to-Revenue Ratios (SaaS benchmarks)
| Function | Benchmark ratio |
|----------|-----------------|
| Sales (AE) | 1 AE per $1–2M quota |
| CS | 1 CSM per $1–3M managed ARR |
| Support | 1 agent per X tickets/month (varies by complexity) |
| Engineering | 1 eng per $200–400K ARR (scales with maturity) |
| Marketing | 10–15% of revenue (varies by motion) |
| G&A | 10–15% of revenue at Series B/C |

### Ramp Cost Calculation
```
New hire total cost (first year) =
  Annual salary × 1.25 (loaded)
  × ramp factor (typically 0.5 for partial year + ramp)
  + recruiting cost ($X per hire)
  + equipment ($X)
  + onboarding overhead ($X in manager / team time)
```

## Capex vs. Opex Decision

| Factor | Capex | Opex |
|--------|-------|------|
| Upfront payment | Capitalized, depreciated over useful life | Expensed immediately |
| Cash flow impact | Large upfront, smaller P&L hit per year | Immediate P&L hit |
| Tax treatment | Depreciation deduction over time | Full deduction in year incurred |
| Flexibility | Lower (committed asset) | Higher (cancel subscription) |
| Balance sheet | Increases assets | No balance sheet impact |
| Best for | Long-lived assets (servers, IP, equipment) | SaaS, services, recurring costs |

### Cloud Infrastructure Decision Framework
- If predictable, high-volume workload: reserved instances (capex-like commitment, opex accounting) = lower cost
- If variable, unpredictable: on-demand (pure opex) = flexibility
- If exploratory: spot / preemptible = cheapest, interruption risk

## Budget Variance Analysis

### Monthly Variance Report Template
```
[Month] Budget vs. Actuals — [Department]

                    Budget      Actual      Variance    Variance %
Salaries & Benefits $X          $X          $(X) fav    -X%
Software / SaaS     $X          $X          $X unfav    +X%
T&E                 $X          $X          $X unfav    +X%
Contractors         $X          $X          $(X) fav    -X%
Other               $X          $X          $X          X%
--------------------------------------------------------------------
TOTAL               $X          $X          $X          X%

YTD:
                    Budget YTD  Actual YTD  Variance    Variance %
TOTAL               $X          $X          $X          X%

Key explanations:
1. Software overage ($X): [Root cause — e.g., "price increase on Salesforce, not budgeted"]
2. Contractor favorability ($X): [Root cause — e.g., "project delayed to Q3"]

Reforecast for full year:
  Prior full-year budget:    $X
  Revised full-year forecast: $X
  Change:                    $X (+/-X%)
```

### Variance Materiality Thresholds
| Threshold | Action |
|-----------|--------|
| < $10K or < 5% | Note in monthly report, no escalation needed |
| $10–50K or 5–15% | Explain in variance report, reforecast line item |
| > $50K or > 15% | Escalate to CFO, budget amendment may be required |

## Budget Request Template (Mid-Year)

```
Budget Request — [Description]
Submitted by: [Name / Department]
Date: YYYY-MM-DD
Amount requested: $X (one-time) / $X per [month/year] (recurring)

Business case:
  Problem: [What situation requires this spend?]
  Solution: [What will this purchase or investment accomplish?]
  
Expected benefits (quantified where possible):
  - [Outcome 1]: saves X hours/month = $X/year
  - [Outcome 2]: enables $X revenue
  - [Outcome 3]: reduces risk of $X loss

Alternatives considered:
  - [Alternative 1]: rejected because [reason]
  - [Alternative 2]: rejected because [reason]

Timeline: [When is budget needed? What are the milestones?]

Risk of not approving: [What happens if this is declined?]

Approval required from: [Finance + relevant exec]
```

## Budget Governance

### Budget Amendment Policy
- Reallocation within department (same total): manager approval
- Reallocation across departments: CFO approval
- New spend > budget total: exec + CFO + board notification above threshold
- Emergency spend: CEO authority up to $X, then board

### Forecast Cadence
| Company stage | Forecast frequency |
|--------------|-------------------|
| Seed / Series A | Monthly |
| Series B+ | Monthly (detailed) + rolling 12-month |
| Pre-IPO | Weekly during planning; monthly ongoing |
| Public | Quarterly guidance + monthly internal |
