Resource Allocation Calculator
Distribute your team's working hours across up to three projects based on priority weights and a target utilization rate. Use it during sprint planning or project kickoffs to ensure effort is proportional to business value.
About this calculator
This calculator answers a practical question: if your team has a fixed pool of hours each week, how many should each project receive? The core formula is: Resource Allocation = (totalResources × utilizationRate / 100) × (projectPriority / sumOfAllPriorities). First, the total available hours are scaled down by your target utilization rate — for example, 80% utilization on 100 hours yields 80 effective hours. Those effective hours are then split proportionally among projects using their priority weights. A project with a weight of 50 out of a total weight of 100 receives exactly half the effective hours. This approach prevents over-allocation, protects buffer time, and makes trade-offs explicit and data-driven rather than political.
How to use
Suppose your team has 200 hours/week, a utilization rate of 80%, and three projects with priority weights of 50, 30, and 20. Step 1 — effective hours: 200 × 80 / 100 = 160 hours. Step 2 — total priority: 50 + 30 + 20 = 100. Step 3 — Project 1 allocation: 160 × (50 / 100) = 80 hours. Project 2: 160 × (30 / 100) = 48 hours. Project 3: 160 × (20 / 100) = 32 hours. Total allocated = 160 hours, matching the effective capacity exactly. Adjust weights whenever priorities shift.
Frequently asked questions
What is a good target utilization rate for a software development team?
Most project management practitioners recommend a utilization rate between 70% and 80% for knowledge workers. Targeting 100% leaves no room for unplanned work, meetings, or learning, which inevitably leads to burnout and missed deadlines. A buffer of 20–30% keeps the team sustainable and allows them to absorb urgent requests without disrupting planned work. Some high-maturity teams track actual utilization over time and adjust the target based on historical data.
How should I choose priority weights for competing projects?
Priority weights should reflect the relative business value, strategic importance, or revenue impact of each project. One common approach is to score each project on criteria like ROI, customer commitment, and risk, then normalize the scores into weights. Weights don't need to add up to 100 — the calculator computes each project's share as its weight divided by the sum of all weights. Involving stakeholders in the weighting process also builds buy-in for the resulting allocation.
When should I recalculate resource allocation during a project?
Recalculate whenever a significant change occurs — a new project is added, a deadline shifts, a team member joins or leaves, or a stakeholder changes a project's priority. Many teams run a lightweight re-allocation exercise at the start of each sprint or planning cycle. Waiting too long between recalculations means your team may be spending hours on low-priority work while high-priority deliverables slip. Treat this calculator as a living planning tool, not a one-time exercise.
