Time Tracking Calculator: What Your Logged Hours Cost

Nine hours. That’s what a bathroom tile job ran over last spring before I caught it. The crew was logging time on paper, the sheets sat in a truck for two weeks, and by the time I added them up the profit was already gone. A time tracking calculator would have flagged it on day two.

If you log hours but never turn those hours into a dollar figure, you are flying blind. Tracked time only matters when you know what it costs you. That is the whole job of a time tracking calculator: take the hours your crew punches and convert them into real, burdened labor cost you can compare against the bid.

Quick Answer

A time tracking calculator multiplies logged work hours by your burdened labor rate to show the true cost of a job’s labor. Burdened rate means base wage plus payroll taxes, workers comp, and insurance, usually 30 to 40 percent on top of the wage. Track estimated hours against actual hours and you catch overruns before they eat your margin.

Why Logged Hours Are Not the Same as Your Wage

Here is the mistake I see new contractors make. They pay a carpenter $30 an hour, so they figure 40 hours costs them $1,200. Wrong. That $30 is the wage. It is not what the employee actually costs your business.

On top of the wage you carry:

• Payroll taxes - FICA alone is 7.65 percent (Social Security plus Medicare), per IRS employer rules
• Workers compensation - varies by trade and state, often 8 to 20 percent for construction
• General liability and unemployment insurance
• Paid time off, holidays, and any benefits you offer

Stack those up and your true cost lands 30 to 40 percent above the base wage. That gap is your labor burden. A carpenter at $30 an hour really costs you closer to $40 an hour once burden is loaded. Run your own number in the burdened labor rate calculator so you are not guessing.

Skip the burden and every estimate you build is short. Quietly. Job after job.

Worked Example: One Carpenter, One Week

Let’s say a carpenter logs 40 hours on a kitchen job. Base wage is $30 an hour, which sits right in the typical range for carpenters (BLS pegs the median around $31.55/hr). Apply a 35 percent burden.

Line item	Calculation	Amount
Base wage	40 hrs x $30	$1,200
Labor burden (35%)	$1,200 x 0.35	$420
True labor cost		$1,620

That $420 is the part most contractors forget. On a single week it is the difference between a job that pays and a job that pays you nothing. Now imagine a three-week job with a two-man crew. The burden you ignored is over $2,500.

Worked Example: Estimated Hours vs Actual Hours

This is where a time tracking calculator earns its keep. You bid the job on a number of hours. Then you track what actually happened.

Say I estimated 32 hours to tile a bathroom floor and walls. The crew tracked 41 hours. Here is the damage at a burdened rate of $40.50 an hour ($30 wage plus 35 percent).

	Hours	Burdened rate	Labor cost
Estimated	32	$40.50	$1,296
Actual	41	$40.50	$1,660.50
Overrun	9		$364.50

Nine hours over. That $364.50 came straight out of profit. If I had been tracking against the estimate daily, I would have seen the gap forming by hour 20 and either adjusted the crew or flagged a change order. Caught early, an overrun is a conversation. Caught at invoice time, it is a loss.

Tracking Methods Compared

Not every tracking setup gives you usable numbers. Here is how the common ones stack up for a small to mid contractor.

Method	Setup cost	Real-time cost view	Catches overruns
Paper timesheets	Free	No	Rarely, too slow
Spreadsheet	Free	Manual	Only if you update daily
Time tracking app	$8-$20/user/mo	Yes	Yes, automatically
Integrated estimate tool	Bundled	Yes	Yes, against the bid

Paper works until it doesn’t. The problem is lag. By the time the sheets reach the office, the job is done and the money is spent. A job costing spreadsheet template is a solid free upgrade if you commit to updating it daily. Better yet, tie the hours to the original estimate so the comparison is automatic.

Regional Reality on Labor Rates

Wages are not flat across the country, so your burdened cost shifts with your market. These are rough adjustments off a national carpenter wage, based on BLS regional wage data and my own field experience working from Alaska to Louisiana.

Market	Wage vs national
Seattle / PNW	+25% to +35%
New York metro	+30%
National average	baseline
Phoenix / Southeast	-10% to -15%
Rural Midwest	-20%

Prices vary by region, and 2026 wage pressure from the skilled labor shortage is pushing the high markets even higher. Pull your own local wage data and get multiple bids on subs before you lock a rate into your template.

Common Mistakes That Wreck Your Numbers

• Tracking hours but not loading burden. The single most common one. Your cost is always higher than the wage.
• Updating the log weekly instead of daily. Overruns hide in the lag. Daily entries catch them.
• Rounding everyone to 8 hours. Real days run 7.5 or 9.25. Round and your data is fiction.
• Forgetting drive time and setup. If you pay for it, track it. It is real labor cost.
• Never comparing actual to estimated. Tracked hours with nothing to compare against just tell you the job happened. They don’t tell you if it paid.

I have made most of these myself. The paper-sheets-in-the-truck habit cost me real money before I tightened it up.

How Contractors Actually Use the Numbers

Once you have clean burdened-hour data, three things get easier:

1. Better bids. Last job took 41 hours, not 32? Your next tile bid uses 40. Your estimates get sharper with every tracked job.
2. Faster overrun calls. You see the gap mid-job and decide: push the crew, eat it, or write a change order.
3. Honest job costing. At closeout you know exactly what labor cost, not what you hoped it cost.

For the man-hour side of bidding, our man hours calculator helps you estimate the labor a job should take before you ever swing a hammer.

Frequently Asked Questions

What is a time tracking calculator? It is a tool that converts logged work hours into labor cost by multiplying hours times a burdened hourly rate. The good ones also compare your actual hours against the hours you estimated, so you can see overruns while the job is still open.

How do I calculate labor burden for time tracking? Add up payroll taxes (FICA is 7.65 percent), workers comp, liability insurance, and any benefits or PTO, then divide that total by the base wage. For most construction trades it lands at 30 to 40 percent. So a $22 laborer (the typical going rate) costs roughly $29 to $31 an hour fully loaded. Our labor cost calculator builds this for you in seconds.

Should contractors track time on every job? Yes, even small ones. The whole point is building a history of real production rates. After 10 tracked jobs you stop guessing your hours and start bidding off data. That alone tightens your estimates more than any pricing software.

How much does time tracking cost a contractor? Standalone apps run $8 to $20 per user per month in 2026. The bigger cost is not tracking at all. One missed nine-hour overrun, like my tile job, costs more than a year of a tracking app.

Can I track time in a spreadsheet? You can, and it beats paper if you update it daily. The weakness is discipline. Spreadsheets only work when someone enters hours every single day and ties them back to the original bid.

Get Your Time Back, Not Just Your Hours

The reason I built estimating software in the first place was to stop losing evenings to spreadsheets and stop losing money to overruns I caught too late. Contractors who move off paper and spreadsheets onto EstimationPro report cutting estimate time from a couple of hours down to a few minutes, and they finally see labor cost against the bid in real time.

EstimationPro doesn’t just track your hours. It builds the estimate, sends the proposal automatically, follows up with the homeowner so you win more of the bids you already send, and invoices when the job is done. Try EstimationPro free and get back to the work that actually pays, or get home to your family.
