Every excavation quote in Kenya is a cost calculation wearing a price tag — and the contractors who can show their workings win the jobs the guessers lose, because they know which jobs to chase and which to walk away from. This guide provides the editable formulas for excavator cost per hour and excavator cost per cubic metre Kenya buyers actually use: ownership, fuel, operator, transport and maintenance summed into a machine-hour rate, divided by measured production — an SDLG ownership calculator with model-specific scenario structures, deliberately not another price-list article.
Quick answers if you are pricing now: the six input lines below build the hourly rate; production from the site's own measurement divides it; and the worked example is illustrative arithmetic with assumptions stated, not a rate card. The general earthworks context sits in the earthworks cost estimation guide, the market-rate view in the earthworks rate breakdown and the machine context in the excavator prices 2026 guide; the desk at +254 718 686 967 builds the model with your fleet's numbers.
| The hourly formula | Ownership plus fuel plus operator plus transport plus maintenance, divided by scheduled hours — the machine hour rate calculation every quote rides on |
| The production formula | Measured bank cubic metres per productive hour from the site's own cycles — the denominator that converts cost into price per cubic metre |
| The honesty rule | Every figure is the operation's measured number or a stated assumption — the example below is illustrative arithmetic, not a rate card |
| The guardrail | This is an ownership calculator with model-specific scenario structures — the market rate articles linked above own the going-rate picture; neither replaces the other |

The six input lines of the machine-hour rate
| Line | The editable formula | Where the number comes from |
|---|---|---|
| Ownership | (Purchase price minus residual value) divided by ownership hours, plus finance cost where borrowed | The quotation, the exit assumption and the lender's terms — all dated |
| Fuel | Litres per hour times the delivered price per litre | The machine's measured burn at the site's duty — the logbook, not the brochure |
| Operator | Daily cost divided by scheduled hours | The wage, statutory costs and supervision share — the payroll, honestly loaded |
| Transport | Mobilisation plus moves, spread over the programmed hours | The low-loader quotation and the programme's geography — the transport cost excavation line priced per move count, not hoped |
| Maintenance | Scheduled services plus wear items plus a breakdown allowance, per the duty | The manual's schedule bent by dust and hours, plus the fleet's own history — the maintenance cost per hour the records supply |
| Scheduled hours | The denominator — shift hours the programme actually commits | The contract calendar, with the utilisation gap stated honestly |
Sum the first five, divide by the sixth, and the operation has its excavator cost per hour — the number every tender, hire decision and fleet comparison ultimately prices against.
The production line: converting cost into price
The second formula divides the hourly rate by production cubic metres per hour — measured bank cubic metres per productive hour from the site's own cycles: face time, swing, dump, return, with the delays the site actually produces. And because production is the denominator, it disciplines twice: the fuel cost per cubic metre line and the hourly cost line fail or hold together, and idle time punishes both. The measurement is deliberately simple — cycles timed across a shift, loads counted, swell applied — because a measured rough number beats an assumed precise one on every contract in the country. The operator cost excavator Kenya line divides by the same production, which is why operator technique and shift planning belong in the same spreadsheet as the fuel log.
An illustrative worked example, assumptions stated
The structure below shows the arithmetic on deliberately simple assumptions — illustrative, not prescriptive, and rebuilt with the operation's own numbers before any real pricing:
| Line | Illustrative assumption | Arithmetic |
|---|---|---|
| Ownership | Machine and finance averaged over planned ownership hours | Line value in currency per hour |
| Fuel | Measured litres per hour at the site's duty | Litres × delivered price |
| Operator | Daily cost over scheduled hours | Line value per hour |
| Transport | Mobilisation spread over programmed hours | Line value per hour |
| Maintenance | Schedule plus wear plus allowance | Line value per hour |
| Hourly rate | Sum of the five lines | The machine-hour rate |
| Production | Measured bank cubic metres per productive hour | The site's own cycle measurement |
| Cost per m³ | Hourly rate ÷ production | The number the tender carries |
Model scenarios: the calculator across the range
Across the SDLG excavator cost Kenya range, the formula's shape holds while the inputs move. Compact machines carry lower ownership and fuel lines but the same operator, transport and maintenance structure; production-class machines divide the rate across higher production where the face and trucks feed them; heavy machines concentrate every line and punish idle time hardest. The scenario discipline: run the calculator per machine per duty — the class that wins on hourly cost can lose on cost per cubic metre where its production goes unfed, and the reverse. The model-specific scenarios are the desk's daily work; this page's job is the formula the scenarios are built on.
Relationship to the going-rate articles
This calculator and the market-rate guides are complements, not competitors: the rate breakdown describes what the market charges; this page calculates what the machine costs. The two numbers meet at the tender: price above cost, margin between them, and the excavator ownership cost formulas above are where the margin is defended. Quoting from the market rate alone leaves the margin to luck; quoting from cost alone ignores the market. The professional bid carries both.
Misuse patterns that corrupt cost calculations
- The brochure burn: fuel from the nameplate instead of the logbook — the most optimistic number in the industry.
- Hours assumed, not scheduled: the denominator set by hope — utilisation discovered at the invoice.
- Transport priced at zero: mobilisation absorbed into optimism — the move count priced per programme, not per memory.
- Production from a cousin site: cycles borrowed from different ground and trucks — the measured site number is the only honest one.
- The single quote, eternal: inputs from last year's prices — every line dated or the model lies quietly.
Five checks before the number is trusted
- Every input is dated and sourced: quotation, logbook, payroll, low-loader quote, service records — or a stated assumption.
- The denominator is scheduled hours: the programme's real calendar, utilisation gap stated.
- Production is measured: cycles timed on the site's ground with its trucks.
- The structure is editable: formulas live in the operation's spreadsheet, refreshed per contract.
- The market cross-check is run: cost per m³ compared against the going-rate guides before the tender leaves.
Working the knowledge with the desk
Send the machine, duty and programme to +254 718 686 967 and the desk returns the model populated — ownership lines from the written quotation, fuel from the class's measured duty, production assumptions from the site's description, all editable and dated. The calculator is free; the quotation within 24 hours carries the real numbers. The contractors who know their cost per cubic metre stop chasing the jobs that lose money and start winning the ones that make it — and in a market where everyone quotes, the workings are the moat.
Frequently asked questions
1. How do I calculate excavator cost per hour?
Sum ownership, fuel, operator, transport and maintenance, divided by scheduled hours — the machine-hour rate every quote rides on, built from the operation's own dated inputs.
2. How do I get cost per cubic metre?
Divide the hourly rate by measured production — bank cubic metres per productive hour from the site's own cycles, with swell applied and delays stated.
3. Where do the inputs come from?
The quotation, the fuel logbook, the payroll, the low-loader quote and the service records — each dated, or carried as a stated assumption the site can correct.
4. Is the worked example a rate card?
No — illustrative arithmetic with stated assumptions; the real pricing replaces every input with the operation's measured numbers before any tender.
5. How does this relate to the market rate guides?
Complements: the rate guides describe what the market charges; this calculator shows what the machine costs — the tender prices between the two.
6. Which machine class wins on cost per m³?
The one whose production feeds the hourly cost — class winners change with the face, trucks and duty, which is why the calculator runs per machine per scenario.
7. How often should the model be refreshed?
Per contract or per quarter — fuel, finance and transport dates drift fastest, and stale inputs price quiet lies into every bid.
8. Who populates the model with our numbers?
The SDLG desk at +254 718 686 967 — machine, duty and programme in, editable dated model out with the written quotation.
