Resource allocation pie chart
Visualize how budget, headcount, or capacity splits across departments or teams.
Budget and resource decisions drive product strategy, but most teams don't have a clear, shared picture of how money and headcount actually split across departments. This template gives you that picture: a single pie chart showing what percentage of your total resource pool — whether that's annual budget, engineers, or working hours — goes to each team.
When to use this template
- Budget planning cycles — at the start of Q1 or fiscal year planning, use this to show leadership and the wider team how you're allocating resources and justify trade-offs.
- Headcount reporting — track how many people sit in each department (or role level) to spot imbalances and plan hiring.
- Capacity planning — if you track engineering hours, use a pie to show what percentage of your development capacity is allocated to each initiative.
How to adapt it
Start by renaming the slices to match your organization and changing the values:
- Add or remove departments — if you don't have a separate Operations team, merge it into a Finance & Admin slice.
- Switch to headcount — instead of dollar amounts, use employee counts or FTE equivalents, and update the title to "Engineering Headcount" or "Total Team Size".
- Show quarter-over-quarter changes — create separate pie charts for Q1, Q2, Q3, Q4 to visualize how resource allocation evolved (or create multiple diagrams and document them side-by-side in your planning doc).
Visual edits regenerate clean Mermaid code, so you can drop the result straight into your board deck, strategic plan, or wiki.

Frequently asked questions
- What is a resource allocation pie chart?
- A pie chart that breaks down a total (budget, headcount, capacity hours) into slices for each team or department. Each slice's size shows what percentage of the total goes to that area, making it instantly clear which teams consume the most resources and where the trade-offs lie.
- When should I use a pie chart versus a bar chart for budgets?
- Use a pie chart when you want to emphasize *composition* — the parts of a whole — and each category is roughly 5–10% or larger. Use a bar chart when you have many categories, want to compare specific values, or need to show comparisons across multiple budgets or time periods.
- How do I update the chart with our actual numbers?
- Open the editor and change the labels (e.g., 'Engineering' → 'Platform') and values (the dollar amounts or headcount). The pie will recalculate automatically. Visual edits regenerate clean Mermaid code.
- Can I break down each slice further, like showing sub-teams within Engineering?
- A simple pie chart cannot nest. Instead, create a second diagram showing Engineering's internal breakdown (e.g., Backend, Frontend, DevOps), and link them in your docs. Or use a stacked-bar chart in a separate diagram for a hierarchical view.
