Budget Burn Rate Calculator

Budget Burn Rate Calculator

Is the project budget on pace to last until completion? This calculator converts current spending into a weekly burn rate and remaining runway.

Weekly Burn Rate = Spent So Far / Weeks Elapsed
Weeks of Runway = (Total Budget - Spent So Far) / Weekly Burn Rate

Example

$100,000 total budget, $40,000 spent over 8 weeks:

Burn Rate = $5,000/week → 12.0 weeks of runway remaining

The Key Health Check

Comparing this calculated runway against the project's remaining planned timeline is the critical next step - if the budget is on pace to run out well before the project's planned end date, that's an early signal worth escalating before it becomes a crisis.

Why Burn Rate Isn't Always Constant

Spending often isn't perfectly even across a project's lifecycle - many projects burn budget faster during active development phases and slower during planning or testing phases, so recalculating this periodically gives a more current picture than a single early estimate.
