- Payroll: staff x wage x 8 hours x days
- BI: recovery after a 72-hour wait
- Per day: what one faster day saves
Estimates only. Your policy and records decide a real claim.

How the downtime calculator works
The calculator adds two costs that start the moment a business closes or slows down.
- Lost revenue = average daily revenue x days closed or limited x the share of operations affected. If only half your space is down, enter 50 percent.
- Payroll during closure = employees on payroll x average hourly wage x 8 hours x days. It assumes you keep paying staff while the doors are closed.
If you select business interruption (BI) coverage, it estimates possible recovery by removing the first 3 days of losses, since many BI policies have a waiting period of about 72 hours. Finally, it divides the total by the number of days to show what each day of downtime costs, which is also what each day of faster drying saves.
Example with the default numbers
| Item | Inputs | Result |
|---|---|---|
| Lost revenue | $4,000 a day x 5 days x 100% | $20,000 |
| Payroll | 8 employees x $18 x 8 hours x 5 days | $5,760 |
| Total downtime cost | $25,760 | |
| Cost per day | $5,152 | |
| Possible BI recovery after 72 hours | Days 4 and 5 only | About $10,304 |
The numbers are simple on purpose. Real losses also include repairs, damaged inventory, extra expenses like temporary space or rental equipment, and customers who go elsewhere. The calculator leaves those out, so treat the result as a floor, not a ceiling.
How Denton County businesses cut downtime
The biggest lever is how fast drying starts and how well the work is planned around your operation.
- Immediate extraction. Every hour water sits, it spreads into more flooring and walls, which adds days.
- Containment. Plastic barriers and negative air machines let you keep unaffected areas open to customers and staff.
- Phased work. Dry revenue-producing areas first, such as the sales floor, kitchen or treatment rooms.
- After-hours scheduling. Material removal and equipment moves outside business hours where possible.
- Daily moisture readings. Clear data on when each area will be dry lets managers plan staffing and reopening.
Mold adds time and rules for commercial buildings. The Texas Department of Licensing and Regulation requires licensed mold assessment and remediation when mold covers 25 contiguous sq ft or more in a commercial building, and the assessor and remediator must be separate. Fast drying is the best way to avoid that step. If it is needed, our mold remediation team works under the IICRC S520 standard.
Records that support a BI claim
BI claims are paid on documentation. Keep recent sales reports, payroll records, receipts for extra expenses, and a timeline of which areas closed and when each reopened. Our photo documentation, moisture maps and drying logs show when the building was dry and ready for repairs. We can work directly with your insurance company and meet the adjuster on site.

FAQ
Downtime calculator questions
Does business interruption insurance cover water damage downtime?
It can, if the physical water damage is a covered loss under your commercial property policy. BI usually starts after a waiting period, often 72 hours, and has limits. Check your policy with your agent.
Why does the calculator include payroll?
Most businesses keep paying key staff during a short closure to avoid losing them. That payroll is a real cost of downtime even though no revenue is coming in.
What if only part of my business is closed?
Enter the share of operations affected. A restaurant with the dining room open but the bar closed might enter 30 percent. Partial operation is common when containment is set up.
How long does commercial drying usually take?
Many commercial spaces dry in about 3 to 5 days once equipment is running. Large buildings, concrete slabs and Category 3 water can take longer.
Is the result what my insurer will pay?
No. It is an estimate to help you plan. Actual BI payments depend on your policy terms, limits, waiting period and documented losses.
