Fleet economics
Fleet operating-cost estimator
Compare petrol or diesel with electric for two-wheeler, three-wheeler and light-van fleets, using assumptions you can see and change.
Methodology
How the estimate is calculated
The model is deliberately simple and fully transparent. It is built from physical quantities (distance, fuel and energy use) and prices, not from a fixed percentage.
Formulas
- Monthly distance
- fleet size × daily km × operating days
- ICE fuel cost
- monthly km × (L / 100 km ÷ 100) × fuel price
- ICE maintenance
- monthly km × maintenance cost per km
- EV energy cost
- monthly km × (kWh / 100 km ÷ 100) × all-in energy price
- EV maintenance
- monthly km × maintenance cost per km
- Monthly savings
- ICE (fuel + maintenance) − EV (energy + maintenance)
- Annual savings
- monthly savings × 12
- Cost difference
- monthly savings ÷ ICE monthly cost
- CO₂ abated (annual)
- (ICE litres × fuel factor − EV kWh × grid factor) × 12 ÷ 1000, in tonnes
Default assumptions (illustrative)
These defaults are illustrative placeholders, not Integride operating data, and have not been validated in a pilot. Replace them with your own figures. Base values are held in USD and shown below in Australian dollars (AUD, the default display currency) at the planning rate in the table that follows; visitors can switch currency in the calculator.
| Assumption | Two-wheeler | Three-wheeler | Light delivery van |
|---|---|---|---|
| Daily distance (km) | 90 | 100 | 120 |
| ICE fuel (L / 100 km) | 2.5 | 5 | 10 |
| EV energy (kWh / 100 km) | 4 | 8 | 20 |
| ICE maintenance (AUD / km) | 0.03 | 0.045 | 0.09 |
| EV maintenance (AUD / km) | 0.015 | 0.027 | 0.0525 |
| Fuel price (AUD / L) | 1.5 | 1.5 | 1.65 |
| Fuel type | petrol | petrol | diesel |
- All-in EV energy price: 0.6 AUD / kWh, covering the battery-swap service, not only electricity.
- Operating days: 26 per month, 12 months per year.
- Emission factors: petrol 2.31, diesel 2.68 kg CO₂ per litre; grid 0.45 kg CO₂ per kWh (illustrative regional average, to be verified).
Currencies and planning rates
The estimator opens in AUD. Switching currency re-expresses the four editable prices at the planning rates below, keeps any edits you have made, and scales the allowed ranges. The rates are round-number approximations for illustration, not live market rates; enter your own local prices for a meaningful result. Volumes, efficiencies and CO₂ do not depend on currency.
| Currency | Code | Units per 1 USD |
|---|---|---|
| Australian dollar | AUD | 1.5 |
| US dollar | USD | 1 |
| New Zealand dollar | NZD | 1.7 |
| Pound sterling | GBP | 0.78 |
| Euro | EUR | 0.92 |
| Nigerian naira | NGN | 1500 |
| South African rand | ZAR | 18 |
| Kenyan shilling | KES | 129 |
Operating cost is not total cost of ownership
The estimate covers energy and maintenance only. It excludes:
- Vehicle purchase price, financing and depreciation
- Insurance, licensing, taxes and duties
- Battery replacement and residual value
- Charging / swap infrastructure capital cost
- Driver or operator labour
- Downtime, route differences and payload effects
Results are modelled estimates under the stated assumptions, not guarantees or measured Integride results.
