Project Budget Tracker

Track actual spend against budget with forecast at completion. The key column is Forecast at Completion -- that is where you will finish, not where you are today. Used by: Project managers, quantity surveyors, programme managers.

Instructions: Copy this table into Google Sheets or Excel. Add your own work packages. The Variance column = Approved Budget - Forecast at Completion. Update monthly. The Committed Costs column captures signed contracts before work begins -- this is your early warning of overruns.

Change Order Log

Track every scope change request. Essential for preventing scope creep from silently driving overruns. Used by: All project types -- construction, IT, government.

IDDescriptionRequested ByDateCost ImpactSchedule ImpactStatusApproved ByApproval Date
CO-001Additional CCTV cameras in car parkClient security team15 Jan+$8,5000 daysApprovedJ. Smith (PM)22 Jan
CO-002Upgrade to commercial kitchen specificationOperations director28 Jan+$34,000+3 daysRejected----
CO-003Change entry door from aluminium to timberDesign team2 Feb+$1,2000 daysPending----
Critical rule: No work begins on a change until it has Approved status. Rejected changes are recorded permanently -- they are evidence if the requester later claims the work was always in scope. Pending changes that start accumulating are a warning sign.

Frequently Asked Questions

What should a project budget tracker include?

A project budget tracker should include: original estimate, approved budget, committed costs (signed contracts), actual spend to date, forecast at completion, and variance. Organise by work package. Update monthly at minimum. The key column is "forecast at completion" -- not "spent to date", which tells you where you are, not where you will finish.

What is a change order log and why is it important?

A change order log tracks all requested scope changes: what was requested, by whom, the cost impact, schedule impact, approval status, and approval date. It is essential for preventing scope creep. Every approved change should increase the budget baseline; unapproved changes should not be built. Without a log, scope creep is invisible until the project is significantly over budget.
