Fixed-Price Margin Rescue

Methodology & Interpretation Guide

Fixed-Price Margin Rescue answers the question a fixed-price project raises part-way through delivery: where is the margin heading, and what realistic combination of actions would bring it back to target.

Model FPMR-1.0

What the utility answers

A fixed-price project can be on schedule and still be losing money. This utility takes what the project was priced at, what has been spent, how far the work has got and what is left to do, and works out where the margin will land if nothing changes. It then translates the gap into the specific amounts that would close it, and compares the rescue paths you have told it are realistic.

  • Where is the margin heading, and how far has it moved from what was priced?
  • What is the estimate at completion?
  • How much additional revenue would restore the target margin?
  • How much delivery cost, or how many hours of effort, would do the same?
  • How much more effort can the project absorb before the margin falls below a floor?
  • Which combination of the levers I actually have closes the gap, and can the target still be recovered at all?

Fixed-price project economics

On a fixed-price project the revenue is largely settled when the contract is signed, and almost everything that happens afterwards happens to cost. Every hour of rework, every defect cycle and every underestimated task comes straight out of the margin. That asymmetry is why margin erosion on fixed-price work is usually discovered late: nothing on the revenue side announces it.

Revenue

Revenue here means the contract value the project's margin is measured against: the fixed price, plus any change revenue that has been formally approved. It is project revenue at completion, not what has been invoiced or recognised so far.

Delivery cost

Delivery cost is the direct cost of delivering the project: the people working on it at their cost rates, plus any direct non-labour cost such as licences, travel or third-party services you choose to include. Corporate overhead is excluded unless you build it into your rates, which is stated again under limitations because it changes what the margin means.

Gross profit

Gross profit is revenue less delivery cost. It is the money the project contributes after paying for its own delivery.

  • Gross profit = Revenue - Delivery cost

Gross margin

Gross margin is gross profit as a share of revenue. It is the main profitability measure throughout this utility, because it is the one a fixed price is normally set against and the one a commercial review asks about.

  • Gross margin = Gross profit / Revenue

Gross margin and markup are different numbers

Markup measures profit against cost; margin measures it against revenue. A project costing 70 and sold for 100 has a 30% margin and a 42.9% markup. Treating one as the other is the most common way a commercial conversation goes wrong, so markup is shown only for reference and never used in any calculation here.

  • Markup = (Revenue - Cost) / Cost

Actual cost to date

What the project has actually spent on delivery so far, from your time and cost records. It is the one figure in the analysis that is a fact rather than a forecast, which is why it anchors the estimate at completion.

Estimate to complete (ETC)

The delivery cost still to be spent from today to completion. By default it is the remaining effort multiplied by one blended cost rate. If you use the role-based forecast, each role's remaining effort is costed at its own rate and the total gives the blended rate every rescue calculation then uses. Known unplanned effort and any other remaining direct cost are added on top.

  • ETC = Remaining effort x Cost rate + Unplanned effort x Cost rate + Other remaining direct cost

Estimate at completion (EAC)

What the project will have cost when it finishes: what has already been spent plus what is still to be spent. It is the single most important cost figure in the analysis.

  • EAC = Actual cost to date + ETC

Forecast revenue

Forecast revenue at completion is the baseline contract value plus approved change revenue. It deliberately excludes anything not yet approved.

  • Forecast revenue = Baseline revenue + Approved change revenue

Approved and pending change revenue are kept apart

Approved change revenue has been agreed and is expected to be recognised, so it counts in the forecast. Pending or unapproved change value has not, so it never counts. It is shown separately, with what the margin would be if it were approved, and can be used as the limit on the revenue rescue lever. Counting it early is how a project reports a healthy margin right up to the week the client says no.

Original margin

The margin the project was priced at: baseline revenue less the original planned delivery cost, over baseline revenue. It is the reference point every movement in the margin bridge is measured from.

Target margin

The margin you want to protect or recover. It can be the original margin, or something lower that the business would accept. If you leave it blank, the original margin is used and the result says so. It is a separate concept from the minimum acceptable margin.

Forecast margin

Forecast gross profit over forecast revenue: where the margin lands if delivery continues as forecast and nothing is done.

  • Forecast gross profit = Forecast revenue - EAC
  • Forecast gross margin = Forecast gross profit / Forecast revenue

Margin erosion

The movement from original margin to forecast margin, in percentage points, together with the fall in gross profit in money. A margin moving from 31.2% to 21.7% has fallen by 9.5 points. It has not fallen by 30%, and the two statements lead to very different conversations.

Cost overrun

The estimate at completion less the original planned delivery cost. A negative figure is an underrun. The margin bridge splits the overrun into the cost pressure already incurred (spend against the planned cost of the work done), the remaining forecast against the remaining budget, and unplanned effort on its own line, so each can be acted on separately.

  • Forecast cost overrun = EAC - Original planned delivery cost

Cost performance, and why it is not margin

Where work completion is reported, the planned cost of the work done so far is the original planned cost times the completion percentage. Dividing that by actual cost gives a cost performance ratio, the CPI familiar from earned value management. It is a supporting signal only. CPI describes cost efficiency against plan; gross margin describes project economics against revenue. A project can run a CPI below one and still land its margin if the remaining work is cheap, or run a CPI of one and lose money on a thin price.

  • Planned cost of work done = Original planned cost x Completion %
  • Cost variance to date = Planned cost of work done - Actual cost to date
  • CPI = Planned cost of work done / Actual cost to date

Revenue required to restore the target margin

Holding the forecast cost where it is, how much more revenue would bring the margin back to target. The calculation uses gross-margin algebra. Adding the cost gap to revenue understates the ask, because every additional rupee of revenue raises the profit the target requires as well.

  • (Revenue + X - Cost) / (Revenue + X) = Target margin
  • Revenue + X = Cost / (1 - Target margin)
  • X = Cost / (1 - Target margin) - Revenue

Cost reduction required

Holding revenue where it is, how much delivery cost would have to come out for the margin to reach target. It is also the gross-profit gap: the profit the target requires less the profit currently forecast.

  • Maximum allowable delivery cost = Forecast revenue x (1 - Target margin)
  • Cost reduction required = EAC - Maximum allowable delivery cost, where positive

Effort reduction required

The cost reduction expressed as remaining effort at the current effective cost rate. It is a quantified requirement, not a recommendation: whether that effort can actually be taken out of the plan is a delivery judgement, which is why it is only used as a rescue lever up to the limit you state.

  • Effort reduction required = Cost reduction required / Effective remaining cost rate

Absorbable additional effort

How much more effort the project can take before its forecast margin falls to a threshold. It is measured against the target, and against the minimum acceptable margin where you set one. A negative figure means the threshold has already been crossed, and says by how much.

  • Cost headroom = Forecast revenue x (1 - Threshold margin) - EAC
  • Absorbable effort = Cost headroom / Effective remaining cost rate

Staffing mix and cost-rate improvement

A cheaper delivery mix on the remaining work lowers the blended cost rate. This utility only considers it if you enter the lowest remaining rate you believe is achievable. It never suggests offshoring, contractor replacement or any particular mix on its own initiative: the rate is yours, and so is the judgement about what it would take to reach it.

Rescue constraints are yours, not ours

Three levers exist, and each is only used where you have stated a limit: the most additional revenue you believe is recoverable, the most remaining effort you believe can realistically be removed, and the lowest remaining cost rate you believe is achievable. A lever without a limit is not considered, and no option ever uses more of a lever than you allowed. A rescue plan resting on savings nobody has agreed to is not a plan.

Commercial recovery

Additional revenue through a change request, a scope clarification or a renegotiation, up to the limit you set. It is often the fastest lever and always the least certain, because it needs somebody outside the project to agree. Pending change value is a natural limit to enter here.

Delivery recovery

Removing remaining effort: descoping, simplifying, stopping rework at source, or finishing with less. Each hour removed saves the effective cost rate. It costs the client nothing to agree to and usually costs the delivery team a difficult conversation.

Combined recovery

Often no single lever closes the gap within its limit, and two or three together do. Because every lever can be solved for exactly, each combined option uses only as much of each lever as it needs. The combined options differ in which lever they lean on first.

How the rescue options are generated and ranked

Each lever is tried alone, then every combination of the levers you supplied is evaluated. Different options answer different management priorities, so none of them is labelled best.

  • Target margin recovery: the fewest simultaneous changes that reach the target, then the least additional revenue, then the least effort removed, then the smallest rate change.
  • Minimum revenue ask: the delivery levers are used first, so the client is asked for as little as possible.
  • Minimum delivery intervention: the revenue lever is used first, so the delivery team is disturbed as little as possible.
  • An option that achieves no more margin while needing at least as much of every lever as another is filtered out as dominated.
  • Where two options are identical, one is shown. The same analysis always presents its options in the same order.

When the target margin is not recoverable

Sometimes every lever at its limit still leaves the margin short. The utility says so plainly rather than inventing a recommendation, and shows the best achievable margin, the points still missing, how much more revenue or cost reduction would be needed on top, and how much of each lever was used to get there. A realistic revised margin agreed early is worth more than an optimistic one defended until the final invoice.

Health classification

The forecast is classified as on track (at or above target), watch (short of target by no more than the watch tolerance), at risk (short by no more than the rescue point and above any minimum margin), or rescue required (further short, below the minimum margin, or loss-making). The default tolerance is 2 points and the default rescue point 5 points. Both are KnownShift model settings you can change, not finance standards.

Assumptions

The remaining effort forecast is yours and is used as entered. Unplanned effort is costed at the same effective rate as the remaining plan. Person-days are converted to hours at the productive hours per day you set, eight by default. Nothing in the analysis is random or generated: the same inputs and the same model version always produce the same result, including the order the rescue options appear in, and every saved analysis records the model version it was produced under.

How to read and interpret the result responsibly

Treat the forecast margin as the headline and the rescue options as priced choices rather than instructions. The utility knows the limits you gave it and nothing about whether the client will sign the change or the team can absorb the descope. The most useful output is often the gap between the single-lever answers and the combined one, because that gap shows which conversations have to happen together.

What this model does not claim

  • The result is only as good as the remaining-effort forecast. If the forecast is optimistic, so is every figure built on it.
  • Work completion is entered by you and can be subjective. It affects the cost performance signal and the margin bridge, not the forecast margin itself.
  • Future approved revenue may change, and pending change value is not committed until it is approved.
  • Cost rates exclude corporate overhead unless you include it, so the gross margin here may be higher than a fully loaded figure.
  • Gross margin follows project delivery economics as described in this guide and may differ from your company's accounting or reporting definitions.
  • Rescue options are limited to the constraints you supply. The utility cannot see levers you did not enter, or know whether the ones you did enter are achievable.
  • The utility does not guarantee commercial approval from a client, and a rescue option is not a commitment anybody has agreed to.
  • The health classification thresholds are KnownShift model settings you can change. They are not an industry standard and carry no certification or endorsement.

Every figure this utility produces follows from the information you entered and the assumptions set out above. It is a structured model of one decision, offered to inform professional judgement rather than to replace it or to substitute for your organisation’s own governance.
