Cash. Plan. Decide. Always know how much runway you have.

Financial planning and analysis (FP&A) is the operating discipline of modeling cash, revenue, costs, and scenarios — and using the model to make decisions. For private-company operators, FP&A often falls to the COO or founder until $5M ARR. After that, the most valuable FP&A artifacts are: a rolling cash forecast, scenario plans, and a board-ready P&L view.

§ 01 · Definition

What is financial planning?

Financial planning and analysis (FP&A) is the function and discipline that owns financial modeling, scenario planning, budget vs. actual variance, cash management, and board-level reporting. It bridges accounting (what happened, GAAP) and operating decisions (what to do, forward-looking).

§ 02 · Context

Why financial planning matters in 2026

  • 01

    Cash runway under 12 months requires weekly cash management; over 18 months allows quarterly.

  • 02

    Burn Multiple replaced "growth at all costs" as the FP&A north star — under 1.5 is best-in-class.

  • 03

    Scenario planning is the single highest-leverage FP&A activity — knowing your downside paths prevents panic decisions.

  • 04

    Budget vs. actual variance >10% indicates either planning or operating-rhythm problems, both costly.

  • 05

    For operators, FP&A is the language of the board — speak it fluently or get over-managed.

§ 11 · FAQ

Frequently asked

When does a startup need dedicated FP&A?

Most SaaS startups can survive on founder-led FP&A through ~$5M ARR. Hire a dedicated FP&A lead at $5–15M ARR. Build a team at $15M+ ARR or after Series B.

What is the difference between FP&A and accounting?

Accounting reports the past (GAAP, audit-ready). FP&A models the future (forecast, scenario, decision-making). Accounting is backward-looking and rules-based. FP&A is forward-looking and judgment-based.

What is a good Burn Multiple?

Burn Multiple = Net Burn / Net New ARR. Best-in-class: <1. Good: 1–1.5. Average: 1.5–2. Above 2 indicates capital inefficiency. Above 3 is a red flag for VC investors.

What templates do FP&A teams use?

Annual operating plan (AOP), monthly variance report, board deck financial section, scenario model (base/upside/downside), 13-week cash flow, cap table, and headcount plan.

What tools replace spreadsheets for FP&A?

Mosaic, Cube, Causal, Pigment for full FP&A platforms. Operating intelligence (Fairview) for operator-friendly variance and scenario views. Mostly mid-market+ companies graduate from spreadsheets.
