How to build a construction company budget for the year

A construction company budget starts with revenue you can actually reach (backlog plus realistic new wins), applies the gross margin each type of work really earns, then sets overhead and profit targets the gross profit can support. It ends with a monthly cash plan and a monthly check against actuals.

To build a construction company budget for the year, work in this order: revenue from backlog and expected new work, gross profit from the margins each type of job has actually produced, overhead line by line, the profit target that is left, and finally a month-by-month cash plan. Start from your own job history, not from a revenue goal picked in December. A budget that begins with "we want to do $10 million" and works backward usually skips the question of whether the estimators can bid that much and the crews can build it.

The budget is also a lending and bonding document. A bank or surety may ask for projections and set them next to what actually happened last year. A realistic budget you hit is worth more than an ambitious one you miss by 30 percent.

Step 1: Start with backlog

List every signed job with the revenue left to earn and when you expect to earn it. That is your backlog, and it is the most reliable part of next year's revenue. Spread it by month using each job's schedule. Be honest about slow starts; a job that has not broken ground by February rarely burns its revenue on the original curve.

Step 2: Plan new work from your bid numbers

Subtract backlog from the revenue you want to reach. The gap is new work you must win and partly build within the year. Divide by your historical hit ratio to see how much you need to bid. If the answer is more than your estimating team can handle, the target is wrong, not the math. See how to calculate a bid hit ratio if you do not track it yet.

Step 3: Apply real gross margins by work type

Use the margins finished jobs actually earned, not the margins they were bid at. Split them by the kind of work: negotiated versus hard bid, public versus private, service versus project. A blended average hides that one segment may be carrying the other. If jobs regularly finish below bid, read how to find margin fade on construction projects before trusting any margin assumption.

Step 4: Budget overhead line by line

Start from last year's actual overhead by account, then add known changes: raises, a new hire, insurance renewal, software, a vehicle replacement. Include a market salary for the owner. Overhead should be set from what the company needs, then tested against what gross profit can pay for. A Construction Executive article on surety underwriting offers a rule of thumb that gross profit should be enough to cover 12 months of overhead. If it does not, cut overhead, raise margin, or lower the volume that requires the overhead.

Step 5: Set the profit target

Gross profit minus overhead is operating profit. Decide what the company needs to keep after taxes and distributions to grow working capital, since working capital drives bonding and borrowing. The same article cites rules of thumb of working capital around 10 to 15 percent of annual revenue and a backlog about equal to one year's revenue. Treat those as one source's benchmarks, not rules, and ask your surety what it wants to see.

Step 6: Turn it into a monthly cash budget

Profit and cash are not the same thing in construction. Retainage, slow pay, and front-loaded material purchases mean a profitable month can still drain the bank account. Lay out expected billings, collections (with your real days to pay), payroll, sub payments, and overhead by month. The construction cash flow template and how to forecast cash flow for a construction business cover the mechanics.

Step 7: Compare to actuals every month

A budget nobody looks at after January is a wish list. Each month, compare revenue earned, gross profit, overhead, and cash to the plan. Explain variances over a threshold you set in advance. Re-forecast the rest of the year at midyear if backlog or margin has moved a lot. Keep the original budget on file next to the re-forecast so you can see how far the plan moved and why.

Worked example: an $8 million budget

Say a commercial contractor wants $8,000,000 of revenue next year. The figures below are illustrative.

Example annual budget build
LineAmountNote
Backlog to be earned next year$3,200,000From signed jobs and schedules
New work to win and earn$4,800,000Target minus backlog
Historical hit ratio20%From last two years of bids
Volume to bid$24,000,000$4,800,000 ÷ 20%, before allowing for jobs that start late
Gross profit at 16% realized margin$1,280,000Actual finished-job margin
Overhead budget$940,000Last year plus one PM hire and insurance increase
Operating profit$340,000About 4.3% of revenue

The $24 million bid number is the first reality check. If the two estimators bid $15 million last year, either the company hires another estimator (more overhead), raises its hit ratio by bidding more selectively, or lowers the revenue target. The second check is margin. If realized margin slips from 16 to 14 percent, gross profit drops by $160,000 and operating profit falls by almost half. Running the budget at two or three margin levels shows the owner how thin the cushion is.

Who should build the budget

The owner sets direction, but the numbers should come from the people closest to them. Project managers supply backlog timing and expected margins on their jobs. The chief estimator supplies bid volume and hit ratio. The office manager or bookkeeper builds the overhead lines from last year's general ledger. The CPA or outside accountant can check that the budget lines up with how the financial statements are prepared, which matters if the budget will be shared with a bank or surety. Getting each person to sign off on their piece makes the monthly variance review easier, because nobody can claim the number was handed to them.

Mistakes to avoid

  1. Starting from a revenue wish. Start from backlog and bidding capacity.
  2. Using bid margins instead of realized margins. The budget inherits every bit of fade.
  3. Forgetting the overhead that growth requires. More volume usually means more PMs, more trucks, more office help.
  4. Skipping the cash budget. Profitable growth can still run out of cash.
  5. Setting it and forgetting it. Monthly variance review is where the budget earns its keep.

Frequently asked questions

When should a construction company build next year's budget?

Start in the fourth quarter, once you have a solid view of year-end backlog and the current year's realized margins. Finish it before the new year so January actuals can be compared against it.

What should a contractor's annual budget include?

Revenue from backlog and planned new work, gross profit by type of work, a line-item overhead budget, a profit target, planned equipment or capital purchases, and a month-by-month cash budget.

How do I budget revenue when most of next year's work is not signed yet?

Budget signed backlog first, then plan new work from your bid volume and historical hit ratio. Run the budget at a lower and higher volume as well, so you know what overhead you can carry if wins come slower.

Do sureties and banks look at the annual budget?

They may. When a lender or surety asks for projections, it can compare them with your past results, so a budget grounded in your actual history carries more weight than an aggressive target.
