Estimating

Overhead and profit markup in a construction estimate, in the right order

An estimate starts with direct costs and ends with a price that carries general conditions, overhead, contingency and profit. The order in which those markups are applied, and what each one is a percentage of, changes the total. In Fidrel you add each markup as a percentage or an amount, choose its basis, put the markups in order and see the result line by line. The numbers on this page are only an illustration, not a benchmark.

Where markups go wrong

Every markup on the same base

Overhead, contingency and profit are all applied to the direct costs, so none of them is applied to the others. Whether that is intended depends on how your company prices, and in a spreadsheet it is easy to do it by accident.

A markup that quietly skips a scope

The markup formula covers rows 5 to 80 and a late addition sits in row 81. The total looks plausible and is short by the markup on one division.

Markups typed over the estimate

Someone changes a percentage in a cell after the estimate was reviewed. Nothing records what the markups were when the estimate was approved.

The arithmetic, with round numbers

Illustrative figures: direct costs are 1,000,000 dollars. General conditions at 10 percent on direct costs add 100,000, so the subtotal is 1,100,000. Overhead at 5 percent on the subtotal above adds 55,000, giving 1,155,000. Contingency at 3 percent on the subtotal above adds 34,650, giving 1,189,650. Profit at 4 percent on the subtotal above adds 47,586, so the estimate total is 1,237,236. Had profit been set on direct costs instead, it would have been 40,000, which is why the basis matters as much as the percentage.

General conditions: a line or a markup

General conditions can be priced as line items, for example a project manager by the month or a tower crane, or added as a percentage markup. Fidrel supports both, and the suggested markup names include General conditions. Choose one way for each cost and avoid carrying the same cost in both, since the markup would then be applied to a cost already in the direct total.

Stacking markups in Fidrel

  1. Step 1

    Finish the direct costs

    Build the estimate in groups and line items with quantity and unit price. Direct costs is the sum of the line items, and it is the first figure shown above Markups and deductions.

  2. Step 2

    Add each markup with a name, a value and a basis

    Press Add markup, name it, and choose Percentage or amount. For a percentage, choose the Basis: on direct costs or on the subtotal above. The suggested names are General conditions, Overhead, Contingency and Profit, and a Discount can be added as a deduction.

  3. Step 3

    Put them in order

    The panel says Calculated in this order. Use Move up and Move down to arrange the markups, because a markup on the subtotal above includes every markup that comes before it. Fidrel recalculates the Estimate total as you reorder.

  4. Step 4

    Limit a markup to part of the estimate

    For a percentage on direct costs, choose Applies to and keep All items, or mark groups as Included or Excluded, or give a group its own percentage under Own %. Then approve the estimate, which saves the calculation with it.

What is saved when the estimate is approved

The calculation is saved when the estimate is approved, and a locked estimate shows when it was approved. Changes are then made in a revision. Each figure is rounded once to the cent, half away from zero, so the page never shows a figure that the saved estimate would change. A markup percentage can be at most 1,000 percent and a deduction at most 100 percent.

What the markups in Fidrel do not do

Fidrel supplies no markup benchmarks, so every percentage and amount is your own decision. Fidrel does not decide whether general conditions belong inside overhead; that depends on your company’s practice and your contract. A markup can be limited to selected groups only when it is a percentage of direct costs, not when it is a percentage of the subtotal or a fixed amount. The estimate is not turned into a bid proposal or a client quote.
