There's often confusion in early-stage companies about which metrics belong to finance and which belong to the business more broadly. In practice, most metrics have financial dimensions — but some sit more naturally in the finance function because they require financial data to calculate correctly, they feed into investor reporting, or they have direct implications for financial planning and decision-making.

Clarifying which KPIs your finance team owns — and building the infrastructure to produce them accurately and consistently — is one of the most practical things you can do to make your financial function more valuable.

The core financial KPIs

The KPIs that every finance function should own, regardless of business model, are: monthly burn rate (the net cash consumed by the business in a given month), cash runway (how many months of cash remain at current burn), gross margin (revenue minus cost of goods or cost of service, as a percentage of revenue), and headcount cost as a percentage of revenue. These four metrics are the minimum set that tells you whether the business is financially healthy and sustainable at its current scale.

Each of these should be calculated consistently, using the same methodology every month, and compared to the prior period and to plan. Inconsistency in how these metrics are calculated — even small inconsistencies, like whether a particular cost is included in gross margin or not — makes trend analysis unreliable and investor reporting confusing.

Model-specific KPIs

Beyond the core set, the KPIs your finance team owns should reflect your business model. For a SaaS business: MRR, ARR, net revenue retention, customer acquisition cost, and LTV:CAC ratio. For an e-commerce business: contribution margin by channel and SKU, customer acquisition cost, average order value, and return rate. For a services business: utilisation rate, revenue per head, and gross margin by client or project type. For a hardware business: bill of materials cost, gross margin per unit, and inventory turns.

These metrics sit at the intersection of finance and operations — they require financial data to calculate but operational context to interpret. The best finance functions don't just produce these numbers; they partner with the relevant business team to explain what's driving them and what decisions they suggest.

The reporting cadence

KPIs are only useful if they're produced and reviewed on a consistent cadence. For most early-stage companies, the right cadence is monthly — close enough to act on trends before they become problems, infrequent enough that the reporting doesn't consume more time than the decisions it enables. Some metrics — cash balance, weekly bookings — may warrant weekly visibility. Others — LTV calculations, cohort analysis — may only need to be updated quarterly. The finance team's job is to design a reporting cadence that gives the business the information it needs at the frequency that's actually useful, without creating reporting overhead for its own sake.
