Float Consumption Calculator

Calculate total float consumed by delay events, remaining float, and EOT entitlement per activity. Essential for preparing and defending Time Impact Analysis under FIDIC and MoW contracts.

How to use - and why float matters in EOT claims
  1. Enter the activity details - name, original planned duration, and total float available at baseline.
  2. Enter delay event duration - the number of days this specific event delayed the activity.
  3. The calculator shows float consumed, remaining float, and whether you have an EOT entitlement. If total delay exceeds available float, the excess days are your EOT entitlement.
  4. Key principle: Under FIDIC and MoW, a delay event only entitles the Contractor to an EOT if it consumes all available float AND pushes the activity onto the critical path. This tool makes that determination instantly.
  5. Add multiple activities to analyse an entire programme section in one view. Export as PNG for your EOT submission.

How EOT entitlement is determined
If Delay <= Float → No EOT. The activity still completes on time after absorbing the delay in existing float.
If Delay = Float exactly → Activity becomes critical. No delay to completion yet, but further events will directly delay the project.
If Delay > Float → EOT entitlement = Delay minus Float. The excess days are the Contractor's justifiable extension claim.
If Float was already zero (critical path activity) → 100% of the delay is EOT-entitlement subject to causation proof.

Float consumption and delay exposure

P6 Float Calculator With Local Schedule Analysis

This float calculator helps project controls teams review how much schedule float has been consumed and where delay exposure is building. It is useful for early warning reviews, extension of time discussions and programme update meetings. Calculations run locally in the browser, so the activity data you enter is not uploaded to a server.

How To Use The Float Calculator

  1. Enter the activity name or reference from the programme update.
  2. Add baseline float, current float and delay or consumption values.
  3. Review the calculated float consumption and remaining float position.
  4. Use the output to identify activities moving toward critical or negative float.
  5. Download or capture the result for project controls and claims records.

What The Calculator Helps Review

Float consumption gives an early warning that schedule flexibility is being used. It can help teams understand whether delays are still absorbed by available float or are moving toward critical path impact.

  • Total float movement between updates
  • Consumed float versus remaining float
  • Activities approaching zero float
  • Negative float and delay exposure
  • Evidence for planning, recovery and EOT discussions

Technical Definitions

Total Float
The amount of time an activity can be delayed before it affects project completion or a key milestone.
Float Consumption
The reduction in available float between a baseline, previous update or current schedule position.
Negative Float
A condition where the schedule shows delay beyond a required completion date or constraint.
Critical Path
The longest controlling path through the schedule, where delays generally affect the completion milestone.

Float Calculator FAQ

Is my schedule data uploaded?

No. The float calculations run locally in your browser. Planix Engineering does not receive or store the activity data you enter.

Can this support EOT discussions?

Yes. The calculator can help organize float movement and delay exposure, but entitlement and causation should still be assessed using the contract, programme records and supporting evidence.

Does float consumption prove critical delay?

No. Float consumption is an indicator of schedule risk. Critical delay should be reviewed with the full programme logic, critical path, data date and contemporaneous records.

Who should use this calculator?

It is useful for planners, claims consultants, project controls engineers and managers reviewing float trends and delay exposure.
