Founder KPI Dictionary: Stop Changing Metrics

Finin2min Startup CFO Desk·June 2026·10 min readKPI DICTIONARYValidated: 17 June 2026

If your KPI definition changes every month, your board does not know whether performance improved or the formula changed.

For broader context, see the Companies Act, MCA and Startup Compliance Hub.

2-minute answer: Write ONE page per core metric (ARR, MRR, logo churn vs revenue churn, CAC, LTV, gross margin, burn, runway) naming the exact formula, the source system it pulls from, the owner who computes it, what is explicitly excluded, and who must approve any future change to the definition. Present the SAME formula every board meeting - if the definition genuinely needs to change, disclose the change and show both the old and new number for at least one transition period, rather than silently swapping metrics when the old one looks worse.

Why boards actually get burned by this

The real failure mode
A founder who reports "50% MoM growth" one month using logo count and "35% MoM growth" the next using revenue is not necessarily lying - but a board that cannot tell the difference will eventually stop trusting EVERY number the founder presents, including the accurate ones. The fix is cheap (a one-page dictionary) relative to the cost of a board that has quietly decided not to trust management’s numbers.

Detailed analysis

Why this matters
A KPI dictionary defines metric name, formula, source, owner, exclusions, update frequency and approval for changes. It prevents founder optimism from becoming reporting inconsistency.

Practical example

Example
Company reports churn by customer count one month and ARR churn next month. Board confusion leads CFO to create KPI dictionary and disclose both logo churn and revenue churn consistently.

Computation logic	Formula, assumptions, exclusions and period consistency.	Working paper and CFO sign-off.
Decision impact	How the output affects pricing, hiring, spend, funding or compliance.	Management note and action tracker.
Diligence evidence	Whether an investor/auditor can verify the number independently.	Indexed folder with contracts, reports and approvals.
