Depreciation, fuel, tyres, maintenance, insurance and labour — all factored in. Know exactly what each machine costs to run per hour or per km, and export professional PDF reports.

Most Operators Don't Know Their True Costs

Quoting a hire rate of £350/day without knowing whether your excavator actually costs £280/day or £180/day to operate is a gamble. Under-pricing erodes margins; over-pricing loses contracts. Knowing your true operating cost per hour is the foundation of a profitable plant hire or fleet operation.

Undercharging on Hire Rates

Without accurate cost-per-hour data, plant hire businesses regularly set rates that don't cover depreciation, tyres or unexpected repairs — especially on older high-value machines.

No Visibility on Asset Profitability

Which machines are making money and which are a drain? Without operating cost data, fleet decisions are based on gut feel rather than numbers.

Spreadsheet Overload

Building and maintaining per-machine cost models in Excel across a growing fleet is time-consuming and error-prone — especially when fuel prices change.

Every Cost Factor Included

FleetBolt's operating cost model covers every major cost driver for plant machinery and commercial vehicles.

Depreciation

Straight-line depreciation based on purchase price, expected working life and residual/salvage value — calculated per hour or km.

Fuel Costs

Diesel or petrol cost per hour/km based on your consumption rate and current fuel price per litre. If you log prices in Fuel Tracking, the latest one pulls straight into the calculator with a single click.

Maintenance & Repairs

Annual maintenance budget spread across working hours/km — covers scheduled services, parts and unplanned repairs.

Tyre Replacement

Tyre cost per hour/km based on expected tyre life and replacement cost — often overlooked but significant for heavy plant.

Labour Costs

Operator labour cost per hour or driver cost per km — optional but important for true all-in cost calculations.

Variable Costs & Other

Catch-all field for insurance, licensing, road tax, storage, or any other variable costs specific to your operation.

Operating Costs Questions Answered

What's the difference between per-hour and per-km costing?

Per-hour costing is best for plant machinery (excavators, telehandlers, generators) where usage is measured in machine hours. Per-km is better for HGVs, vans and vehicles where mileage is the primary metric.

How accurate is the cost-per-hour figure?

As accurate as the inputs. FleetBolt uses your actual purchase price, real fuel consumption, your current fuel prices and your actual service costs — not industry averages. The more complete your data, the more accurate the output.

Can I use this to set plant hire rates?

Yes — this is one of the most common uses. Know your break-even cost per hour, then add your desired margin to set a defensible hire rate. Many operators discover they've been under-charging once they see the full cost breakdown.

Does it work alongside the fuel log feature?

Yes. When you've logged a diesel price in Fuel Tracking, the calculator shows your latest price next to the Fuel Cost field with a one-click 'Use latest price' button — so keeping your cost-per-hour figure current takes seconds, not manual lookups.

Can I export reports for my accountant or finance team?

Yes — generate branded PDF cost reports per machine at any time. Useful for business planning, loan applications, or discussing fleet investment decisions.
