Time and Materials Estimate Template
Download a time and materials estimate template to price labour, materials, equipment, markups, tax, and estimated project costs clearly.
Price Variable-Scope Work With a Clear Cost Breakdown
A time and materials estimate gives a customer an expected project cost based on anticipated labour hours, material quantities, equipment charges, and agreed markups. It is useful when the full scope cannot be confirmed before work begins or when site conditions may affect the amount of work required.
This template helps subcontractors prepare a professional estimate while making it clear that final billing may be based on actual labour, materials, equipment, and other authorised costs. It also creates a consistent starting point for tracking estimated costs against completed work.
What Is a Time and Materials Estimate?
A time and materials estimate is a preliminary cost projection for work that will be charged according to actual resources used. Labour is normally priced using hourly rates, while materials and equipment are charged at cost, at an agreed unit rate, or with a stated markup.
Unlike a fixed-price estimate, a time and materials estimate does not necessarily promise that the work will be completed for one set amount. It should explain how charges will be calculated, what assumptions were used, and whether the estimate includes a spending limit or not-to-exceed amount.
When to Use a Time and Materials Estimate
- Repair work where concealed damage may affect the scope
- Service calls that cannot be fully diagnosed in advance
- Renovation and retrofit work in existing buildings
- Emergency work that must begin before complete pricing is available
- Change-order work with uncertain quantities
- Projects where the customer requests transparent labour and material pricing
- Small jobs where preparing a detailed fixed-price bid is impractical
Who Should Use This Template?
The template is designed for subcontractors and specialty contractors who price work using labour rates, material costs, equipment charges, and markups. Typical users include owners, estimators, project managers, service managers, and office staff.
It can be adapted for electrical, plumbing, HVAC, roofing, concrete, painting, landscaping, excavation, welding, fire-protection, maintenance, and other specialty construction work.
What the Template Should Include
| Section | Purpose |
|---|---|
| Contractor and Customer Details | Identifies the parties, project, site address, and primary contacts. |
| Scope of Work | Describes the work expected to be performed and the limits of the estimate. |
| Labour Estimate | Lists labour classifications, estimated hours, billing rates, and extended amounts. |
| Material Estimate | Records anticipated items, quantities, unit costs, and material markups. |
| Equipment and Other Costs | Captures plant hire, tools, permits, disposal, travel, delivery, and subcontractor charges. |
| Allowances | Provides estimated amounts for items that have not yet been selected or fully measured. |
| Summary | Totals labour, materials, equipment, overhead, profit, tax, and the estimated project amount. |
| Terms and Assumptions | Explains billing rules, exclusions, markup treatment, validity period, and approval requirements. |
| Customer Authorisation | Documents acceptance of the pricing method and permission to proceed. |
How to Use the Template
- Enter the contractor, customer, and project information.
- Describe the anticipated scope and identify any work that is excluded.
- List each labour classification, estimated hours, and hourly billing rate.
- Add expected materials with quantities, unit costs, and any agreed markup.
- Include equipment, delivery, disposal, permits, subcontractor charges, and other direct costs.
- Add overhead, profit, and applicable tax according to the agreed pricing method.
- State whether the estimate has a not-to-exceed amount or requires approval before additional spending.
- Review the assumptions and obtain written customer authorisation before work begins.
An electrical contractor is asked to troubleshoot intermittent power loss in an occupied retail unit. Because the cause may be damaged wiring, a failed breaker, or an overloaded circuit, the contractor estimates 12 electrician hours at £68 per hour, £450 in anticipated materials, £90 for access equipment, and a stated material markup. The estimate notes that hidden damage and after-hours work require separate approval.
Best Practices for Time and Materials Pricing
- Use current labour billing rates rather than payroll rates alone.
- Define how regular time, overtime, supervision, and travel time will be charged.
- State whether material markup applies to purchase cost, delivered cost, or another agreed basis.
- Include expected freight, delivery, disposal, permits, and equipment charges.
- Identify allowances and uncertain quantities separately.
- Set approval thresholds for costs that exceed the original estimate.
- Keep timesheets, receipts, delivery tickets, and equipment records to support final billing.
- Compare estimated and actual costs after completion to improve future estimates.
Common Mistakes to Avoid
- Presenting the estimated total as though it were a guaranteed fixed price
- Failing to explain material markups or equipment charges
- Leaving travel, mobilisation, supervision, or disposal out of the estimate
- Using vague scope descriptions that make final billing difficult to defend
- Starting additional work without documented customer approval
- Billing labour or materials without supporting records
- Failing to notify the customer when costs are approaching an agreed limit
Frequently Asked Questions
Is a time and materials estimate a fixed price?
No. It is generally an expected cost based on estimated labour, materials, equipment, and other charges. The final amount may change according to actual resources used unless the agreement includes a firm cap.
Should material markup be shown separately?
That depends on the agreement and the contractor's pricing policy. Whether shown as a separate line or included in unit pricing, the treatment should be stated clearly and applied consistently.
What is a not-to-exceed amount?
A not-to-exceed amount is a spending limit that the contractor should not exceed without additional customer authorisation. The agreement should explain which costs count towards the limit and how approvals will be handled.
What records support a time and materials invoice?
Useful supporting records include approved timesheets, employee classifications, supplier receipts, purchase orders, delivery tickets, equipment logs, subcontractor invoices, daily reports, and written change approvals.
Can this template be used for change-order work?
Yes. It can help price change work when the exact labour hours or quantities are unknown. The contractor should still document the changed scope, pricing method, schedule impact, and approval requirements.
Build a Clear Record From Estimate to Final Billing
A well-structured time and materials estimate helps the contractor and customer understand how the work will be charged before the job begins. Clear rates, assumptions, approval limits, and supporting records reduce confusion when actual costs are invoiced.
A spreadsheet is a practical starting point for this process. As job volume grows, construction management software such as SimplySub can help subcontractors connect estimates with customers, jobs, time records, expenses, invoices, and job-cost information.
