Estimating and bidding

How to calculate a bid-hit ratio

Divide the number of jobs you won by the number of bids you submitted over the same period. Then run it again by dollar value and by job type, because one blended number hides where your estimating time is actually paying off.

A bid-hit ratio is the share of submitted bids that turn into signed work. The basic formula is jobs won divided by bids submitted, for the same period. Win 9 out of 60 bids in a year and the ratio is 15 percent, which some estimators say as "one in 6.7." That number alone is only a start. Calculate it a second way, by dollars, and then split both versions by job type, client, and delivery method. The split is where the real decisions come from: which general contractors to stop chasing, which job sizes you win, and whether your estimating department is busy or productive.

Most contractors track this loosely in their heads. The ones who track it on paper usually find that half their bidding effort goes to clients who almost never award them anything.

The two formulas: count and dollars

  • Hit ratio by count = number of bids won / number of bids submitted.
  • Hit ratio by dollars = total value of bids won / total value of bids submitted.
  • Bids per win = number of bids submitted / number of bids won (the inverse, which some owners find easier to picture).

The two ratios tell different stories. A high count ratio with a low dollar ratio means you win the small jobs and lose the big ones. That pattern often points to markup that is too high on large work, or a bonding or staffing limit that owners can see. The reverse, a low count ratio with a high dollar ratio, means you win a few large jobs and lose a lot of small ones, which may mean your small-job pricing carries too much overhead or that you are bidding small work you do not really want.

Step by step: how to calculate your bid-hit ratio

1. Build a bid log

Every bid gets one row: bid date, client, project name, job type, public or private, bid amount, estimating hours spent, result, and winning number if you can get it. A spreadsheet works. The construction bid template can serve as the starting record for each one. Log the bid the day it goes out, not at the end of the quarter when half the details are gone.

2. Decide what counts as a bid

Agree on a definition and keep it. A full hard bid with a takeoff counts. A budget number tossed to a GC over the phone probably does not, or it goes in a separate column. If one estimator logs budget numbers and another does not, the company ratio is meaningless.

3. Decide what counts as a win, and when

A win is a signed contract or subcontract, not a verbal "you're low." Projects that never get built, or get shelved for a year, should be marked "no award" and removed from the denominator. Otherwise a run of cancelled projects drags your ratio down for reasons that have nothing to do with your pricing.

4. Pick a period and wait for results

Use a rolling 12 months for the headline number and a quarter for trends. Bids still pending at the end of the period stay out of both the top and bottom of the formula until they resolve. Counting them as losses makes the newest quarter look worse than it is.

5. Calculate the blended ratio, then split it

Run the count and dollar formulas for the whole company. Then run them for each client, each job type, each size band, and public versus private. Ten bids is a thin sample for any one slice, so look for strong patterns rather than reading meaning into a single loss.

6. Add cost per win

Multiply estimating hours by a loaded hourly rate for your estimators, then divide by wins. This turns the ratio into a dollar cost of getting work, which is the number that matters when deciding where to spend next month's bid time.

Worked example: a mechanical subcontractor

Say a mechanical sub logs 60 bids over 12 months, totaling $18,000,000 in bid value. It wins 9 jobs worth $1,980,000. Two other bids were for projects that were never awarded and are excluded. The figures below are an illustration, not industry benchmarks.

Example: blended bid-hit ratio
MeasureCalculationResult
Hit ratio by count9 / 6015%
Hit ratio by dollars$1,980,000 / $18,000,00011%
Bids per win60 / 96.7

The dollar ratio is lower than the count ratio, so the company wins smaller jobs more often. Now split by client type.

Example: the same 60 bids split by client
Client groupBidsWinsHit ratioEstimating hoursHours per win
Three repeat GCs18633%29048
Public hard bids16213%420210
Open invitations from new GCs2614%390390

At a loaded estimator cost of $55 an hour, one win from the repeat GCs costs about $2,640 of estimating time. One win from cold invitations costs about $21,450. Nothing here says to stop bidding new GCs. It says to qualify them before committing 15 hours to a takeoff, and to protect time for the repeat clients who actually award. The process for that filter is in how to decide which construction jobs to bid.

What a good bid-hit ratio looks like

There is no single right number. A specialty sub bidding the same handful of GCs on negotiated work may win a large share. A contractor sending hard bids to every public invitation in the region will win far fewer, because every bid is against the full field and the low number takes it. Compare your ratio with your own history and between your own segments, not with a figure someone quoted at a trade show.

A ratio that is very high can be a warning too. If you win almost everything you bid, your prices may be leaving money on the table. Check how far below second place your winning numbers land. A pattern of winning by wide margins suggests room for more markup.

Mistakes that distort the number

  1. Counting budget prices as bids. They inflate the denominator and make real bidding look worse.
  2. Not logging losses. Estimators remember wins. A bid log with only the jobs you got is a sales brag sheet, not data.
  3. Mixing pending bids into results. Leave them out until they resolve.
  4. Ignoring the dollar ratio. A strong count ratio can hide that you never win anything larger than $250,000.
  5. Never recording the winning number. Without it you cannot tell whether you lost by 2 percent or 20 percent, which are completely different problems.
  6. One ratio for the whole company. Split by estimator, client, and job type, or the number cannot tell you what to change.

How to use the ratio to win more work

  • Cut low-yield bidding. Drop or tighten the segments with the highest hours per win, and put that time into follow-up and relationships with clients who award.
  • Follow up on every loss. Ask for the bid tabulation or at least your rank. The method is in how to follow up on construction bids.
  • Tie it to backlog. If your backlog needs $6 million of new work next year and your dollar ratio is 11 percent, you need roughly $55 million of bids in the pipeline. That math tells you whether your estimating staff is big enough.
  • Review it with pricing. Pair the ratio with margin on won jobs. A rising hit ratio with falling margin means you are buying work.

A bid log works best when it lives next to the estimate and the job, so won bids carry their numbers straight into the project budget. Smart Business Automator keeps bids, projects, and job costs connected, and its estimate to project handoff automation moves a won bid into an active job without retyping the estimate.

Frequently asked questions

What is the formula for bid-hit ratio?

Jobs won divided by bids submitted for the same period. Many contractors also calculate it by dollars: total value of bids won divided by total value of bids submitted.

Should I count projects that were never awarded?

No. If the owner cancels or shelves a project, no one won it. Mark it as no award and leave it out of both sides of the formula.

Is a higher bid-hit ratio always better?

Not always. A very high ratio can mean your prices are too low. Check how far below the second bidder your winning numbers fall and what margin the won jobs actually earn.

How often should I review the bid-hit ratio?

Quarterly works for most contractors, using a rolling 12 months for the headline number so one slow month does not swing the result.

What is the difference between hit ratio and win rate?

They usually mean the same thing. Some companies call the count version the win rate and use hit ratio for the dollar version, so define both in your bid log and stick with it.
