Milestone burn-up staircase
Completed work, productive daily gains, review pauses, and target crossing
The staircase advances by effective work completed and marks every review checkpoint rather than pretending all clocked time becomes progress.
Checkpoint forecast
Milestone review and progress ledger
Each row shows cumulative clocked effort, review overhead, productive completion, remaining work, and completion percentage.

How to forecast the milestone
Use observed productivity, not ideal capacity
- Enter the productive-hour target.
- Record completed work using the same definition.
- Estimate the share of clocked time that becomes accepted progress.
- Add review cadence and effort explicitly.
- Use the checkpoint ledger to update the forecast.
Progress logic
Clocked hours and accepted progress are not interchangeable
Administrative work, correction, clarification, and review reduce the amount of output created by each clocked hour.
The chart keeps review events visible so a project manager can see why cost rises without an equal rise in milestone completion.
Calculation method
Convert clocked effort into productive progress and insert review overhead
The productive share reduces nominal daily hours. Review checkpoints consume labor cost and calendar effort but are reported separately from milestone completion.

Velocity diagnostics
What changes the milestone date most
The forecast separates backlog size, daily input, conversion efficiency, and governance overhead.
Remaining scope
—Accepted productive work still required.
Daily velocity
—Clocked daily effort multiplied by productive share.
Review load
—Future checkpoint effort outside productive progress.
Forecast cost
—Clocked work and review time at the entered rate.
Decision takeaway: Improving productive conversion can move the milestone more than simply extending nominal daily hours.
Forecast checks
Review before promising the milestone
- Completed and target hours must use the same unit.
- Productivity should come from comparable work.
- Review hours may increase near final approval.
- Dependencies can create idle days not modeled here.

Practical applications
Decisions this calculator is designed to support
Payroll coding backlog
A team converts historical entries into approved payroll codes with periodic supervisor review.
What the result clarifies: The staircase distinguishes accepted output from time spent checking it.
Audit evidence milestone
A compliance team needs a forecast for completing a fixed evidence-hour target.
What the result clarifies: Review overhead is visible in cost without inflating progress.
Worked example
Current-input substitution and reconciliation
Model limitations
The forecast assumes stable daily effort and productive conversion. It does not model staff learning, individual availability, queue blocking, quality rejection, changing milestone scope, or nonworking dates.
Timesheet Milestone Calculator FAQ
Why are review hours not counted as milestone progress?
They are treated as governance overhead unless the target explicitly includes review work.
Can completed hours exceed the target?
Yes; remaining work then becomes zero.
What is productive share?
It is the fraction of clocked effort that becomes accepted milestone work.
How is labor cost calculated?
Future clocked work plus review hours are multiplied by the blended rate.
