The 75‑15‑10 rule is a resource‑allocation framework that divides a company’s budget, time, or headcount into three distinct buckets: 75% for core operations, 15% for adjacent growth initiatives, and 10% for high‑risk experimental work.
Origins and purpose of the rule
Unlike the Pareto 80/20 principle, the 75‑15‑10 split emerged in the last two decades within corporate innovation circles. It was popularised by consulting studies that observed the most adaptive firms consistently allocated resources in a pattern close to these ratios. The goal is to give enough fuel to the existing business while preserving capacity for future disruption.
What belongs in each bucket
Core (75%) – Activities that keep the business running: payroll, product maintenance, customer support, and the marketing that generates the majority of revenue. These are low‑risk, predictable streams.
Growth (15%) – Projects that expand the current offering into adjacent markets or new customer segments. Examples include adding a consulting arm to a SaaS product or testing a vegan line in a bakery. They carry moderate risk and usually show results within a year‑plus.
Transformation (10%) – High‑risk, high‑reward experiments such as AI prototypes, AR filters, or new platform ventures. Success rates are low, but a single win can reshape the company’s trajectory.
Applying the rule in practice
Consider a mid‑size marketing agency with $3 million annual revenue. Under the 75‑15‑10 model the agency would allocate $2.25 million to client work (core), $450 000 to test new services like AI reporting tools (growth), and $300 000 to speculative projects such as an Instagram AR filter (transformation). The same percentages can be applied to staff time, ensuring that a team member spends roughly three‑quarters of their week on delivery, a small portion on learning new tools, and a brief stretch on experimental research.
Common challenges
The biggest obstacle is protecting the 10% bucket. When quarterly results dip, finance teams often cut the experimental budget first, starving the pipeline of future growth. Successful companies ring‑fence this allocation with separate budgets, clear metrics, and senior‑level sponsorship.
How the rule compares to other models
Personal‑finance models like 50/30/20 split income into needs, wants, and savings, while the 90/10 startup model puts almost everything into execution with a tiny learning slice. The 75‑15‑10 approach adds a middle tier, giving organizations a structured way to nurture emerging opportunities without neglecting the core.
When to adjust the percentages
The split is a guideline, not a law. In crisis mode firms may shift to 80‑10‑10 to preserve cash, while hyper‑growth firms might use 60‑20‑20 to accelerate new product development. The key is to keep the three‑bucket mindset rather than fixate on exact numbers.
