Ireland version
How it works
Calculate a whole-ownership budget without double counting loan principal as both purchase price and repayments.
This is the Ireland planning view, with monetary inputs and outputs in EUR. A currency label does not establish that a tax rate, construction price, coverage rule or legal limit has been verified locally. The inputs and limitations below describe the actual scope.

Formula
ownership cost = purchase price + purchase fees − resale proceeds + recurring operating costs + finance interest.
Calculations retain numeric precision internally. Displayed values are rounded for readability. Quantities that must be purchased as whole units are rounded up only where the formula explicitly requires it.
Read the inputs before calculating
- Vehicle purchase price: Enter the quantity described by the label.
- One-off purchase taxes and fees: Enter the quantity described by the label.
- Expected sale proceeds at end of ownership: Enter the quantity described by the label.
- Ownership period, years: Enter the quantity described by the label.
- Annual driving distance: Enter the quantity described by the label. The measurement selector converts this physical quantity; it does not change the underlying scenario.
- Annual fuel/charging cost: Enter the quantity described by the label.
- Annual insurance: Enter the quantity described by the label.
- Annual maintenance and repairs: Enter the quantity described by the label.
- Annual tax, parking and other ownership costs: Enter the quantity described by the label.
- Interest only over the ownership period: Enter the quantity described by the label.
Reproducible worked example
The following is a fictional arithmetic example, not a local quote, a verified claimant or a market forecast. Its values are included so the formula can be checked. The form does not automatically confirm any verification checkbox.
| Input | Example value |
|---|---|
| Vehicle purchase price | 30,000 |
| One-off purchase taxes and fees | 2,000 |
| Expected sale proceeds at end of ownership | 15,000 |
| Ownership period, years | 5 |
| Annual driving distance (km) | 20,000 |
| Annual fuel/charging cost | 1,800 |
| Annual insurance | 900 |
| Annual maintenance and repairs | 600 |
| Annual tax, parking and other ownership costs | 500 |
| Interest only over the ownership period | 3,000 |
| Output | Calculated result |
|---|---|
| Purchase price minus resale proceeds | EUR 15,000 |
| Total entered recurring operating costs | EUR 19,000 |
| Total ownership cost | EUR 39,000 |
| Annual equivalent ownership cost | EUR 7,800 |
| Cost per distance unit | EUR 0.39/km |
Interpreting a changed assumption
Start with one complete scenario and change only one input when diagnosing a difference. Recheck units, the period of every rate, whether an amount is recurring or one-off, and whether a cost is already included elsewhere. A larger calculated benefit is not evidence that an assumption is more likely to occur.
Limitations
- Prices, consumption and contract terms are entered scenarios. This is not a retail quote, tax eligibility determination or vehicle safety certification.
- Enter interest, not the sum of all loan payments. Sale proceeds are a scenario, not a valuation; a remaining loan affects cash at sale but must not make the purchase principal count twice.
Frequently asked questions
What does this Vehicle Running Cost result represent?
Calculate a whole-ownership budget without double counting loan principal as both purchase price and repayments. It applies the displayed formula to your inputs; it does not infer omitted facts.
Are the starting amounts verified Ireland prices or legal rules?
No. Numeric defaults are illustrative unless an input or dated reference explicitly identifies a researched component. Currency is EUR; local quotes, eligibility and unsupported rules must be entered and verified separately.
What must I check before relying on the result?
Prices, consumption and contract terms are entered scenarios. This is not a retail quote, tax eligibility determination or vehicle safety certification.
Can I compare or share different assumptions?
Change one assumption at a time and use the browser-local project or share controls. A shared URL contains the encoded input values; do not include information you do not wish to disclose.
