KPIs Every CFO Must Track

CFOs translate business performance into financial health, using KPIs to manage cash efficiency, profitability, and the unit economics that determine long-term enterprise value.

Why These Metrics Matter

The CFO's lens on KPIs is fundamentally about capital efficiency: is the company generating an appropriate return on invested capital, and is the cash position sustainable through the next operating cycle? For SaaS businesses, the CFO focuses on ARR and NRR as the foundation of predictable revenue, gross margin as the profitability floor, and burn rate and runway as the survival metrics that determine fundraising timing. Unit economics (LTV:CAC ratio and CAC payback period) are the CFO's tool for stress-testing whether growth investment will ultimately generate positive returns. A company growing rapidly with a 18-month CAC payback and 4:1 LTV:CAC can justify aggressive growth spending; one with a 36-month payback and deteriorating LTV has a structural economics problem that revenue growth cannot solve. The CFO also owns the operating plan's credibility with investors. Free cash flow margin, operating margin, and EBITDA are the metrics used to demonstrate path to profitability and to position the company on the Rule of 40 spectrum. At the detailed level, churn rate's impact on future ARR cohort trajectories and gross margin's effect on the entire unit economics stack are the mechanisms through which operational decisions translate into financial outcomes.

Your Core KPIs

Every metric includes definition, formula, platforms, causal drivers, and Q&A.

Annual Recurring Revenue
ARR
Annual Recurring Revenue (ARR) is the annualized value of all active subscription contracts, normalized to a one-year period.
Monthly Recurring Revenue
MRR
Monthly Recurring Revenue (MRR) is the total predictable recurring revenue a SaaS business expects to receive each month from all active subscriptions.
Gross Margin
GM%
Gross Margin measures the percentage of revenue remaining after subtracting the direct cost of delivering the product or service (Cost of Goods Sold).
Operating Margin
Operating Margin measures the percentage of revenue remaining after subtracting all operating expenses including COGS, sales and marketing, R&D, and G&A, but before interest and taxes (EBIT).
EBITDA
EBITDA
EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is a widely used measure of core operating profitability that strips out the effects of financing decisions, tax environments, and non-cash accounting charges.
Burn Rate
Burn Rate measures the rate at which a company is spending its cash reserves, typically expressed as a monthly net cash outflow.
Free Cash Flow
FCF
Free Cash Flow (FCF) measures the cash a company generates from operations after deducting capital expenditures required to maintain or expand its asset base.
Customer Acquisition Cost
CAC
Customer Acquisition Cost (CAC) measures the total sales and marketing expenditure required to acquire one new paying customer over a given period.
Customer Lifetime Value
LTV
Customer Lifetime Value (LTV) estimates the total net revenue a business expects to generate from a single customer relationship over its entire duration.
LTV:CAC Ratio
LTV:CAC
The LTV:CAC Ratio compares the expected lifetime value of a customer against the cost to acquire that customer, providing a single efficiency score for the growth model.
CAC Payback Period
CAC Payback Period measures the number of months required for a newly acquired customer to generate enough gross profit to recover the cost of acquiring them.
Churn Rate
Churn Rate measures the percentage of customers or revenue lost in a given period due to cancellations, non-renewals, or downgrades.
Net Revenue Retention
NRR
Net Revenue Retention (NRR) measures the percentage of recurring revenue retained from existing customers over a period, including expansion revenue from upsells and cross-sells, minus contraction and churn.
Gross Revenue Retention
GRR
Gross Revenue Retention (GRR) measures the percentage of recurring revenue retained from existing customers in a period, excluding any expansion revenue.
Revenue Per Employee
RPE
Revenue Per Employee (RPE) measures total annualized revenue divided by the total number of full-time equivalent employees.
Average Order Value
AOV
Average Order Value (AOV) measures the average dollar amount spent per transaction or order, most commonly used in e-commerce and transactional businesses.
/// causal intelligence

How Causal Analysis Changes the Game

For CFOs: Causal analysis of unit economics by customer cohort and acquisition channel helps CFOs identify which segments are actually profitable versus which are producing revenue growth that destroys economic value when LTV is properly accounted for.
