How Much Does It Cost to Run a Car in Ireland?

A practical guide to fuel, insurance, motor tax, servicing and the expenses to consider before buying your next used car.

The asking price is only the beginning of your car budget. To understand car running costs in Ireland, you also need to consider insurance, fuel or charging, motor tax, maintenance, tyres and everyday expenses such as parking and tolls.

Before choosing your next vehicle, browse used cars for sale in Ireland on Bargaindigger and compare the costs of owning each option alongside its advertised price.

Why Your Car May Cost More Than You Think

Research published by the ESRI on 15 September 2026 found that 72% of motorists underestimated their annual motoring costs. The median initial estimate was €2,000, compared with almost €3,000 after respondents worked through their expenses. Those figures excluded the purchase price and depreciation.

The lesson for buyers is straightforward: build a budget around your own journeys, insurance quotation and vehicle condition. A national figure cannot tell you exactly what a particular used car will cost.

Read the ESRI research on car ownership costs for the study details.

Example Monthly and Annual Car Running Costs

The following is an illustrative budget for a used petrol car covering 15,000 km per year. It assumes consumption of 6 litres per 100 km and a fuel price of €2 per litre. These are calculation assumptions, not a current fuel-price quotation or national average.

Expense Annual budget Monthly equivalent Petrol€1,800€150.00 Insurance€750€62.50 Motor tax€200€16.67 Routine servicing€400€33.33 Tyre replacement allowance€250€20.83 Repairs and wear items allowance€600€50.00 One full NCT test€60€5.00 Parking and tolls€360€30.00 Total budget €4,420 €368.33

All amounts except the published NCT fee are illustrative assumptions. Replace them with your own quotations and expected use. Monthly equivalents spread annual costs across 12 months; actual bills arrive at different times. Repair and tyre allowances are money set aside, not a prediction of what you will spend.

This budget excludes the purchase price, depreciation, finance payments, breakdown cover and any additional expenses. It includes one full NCT test during the year; your car may have a different test schedule.

1. Fuel and Charging

Annual distance, driving conditions and consumption all affect your fuel bill. Calculate a petrol or diesel estimate using:

Annual kilometres ÷ 100 × litres per 100 km × price per litre.

For the example above, 15,000 ÷ 100 × 6 × €2 equals €1,800 per year. Use realistic consumption for the exact engine and the type of journeys you make.

For an electric car, multiply annual kilometres divided by 100 by electricity consumption in kWh per 100 km and your charging price per kWh. Allow for charging losses and your likely mix of home and public charging.

2. Car Insurance

Get an insurance quotation for the exact vehicle before paying a deposit. Your premium depends on factors such as your driving history, address, licence, cover requirements and the car itself.

Compare excesses and cover as well as the headline price. If paying monthly, check the total payable rather than assuming it is simply the annual premium divided by twelve.

Our guide to car insurance costs in Ireland explains the factors to consider.

3. Motor Tax

Check the exact tax rate for the vehicle rather than estimating it from engine size or a model badge. Registration date, emissions and tax class can affect the amount.

Use our Irish motor tax guide to understand the systems and find the official rate checker before buying.

4. Servicing, Tyres and Repairs

A service history helps you assess both past maintenance and work that may be due soon. Ask for invoices and check the manufacturer's schedule for the exact engine and gearbox.

Look beyond the next oil change. Timing-belt work, brake replacement, gearbox servicing and tyres can change the affordability of an otherwise attractive car. Obtain a garage quotation for any known upcoming work.

Our guide to car servicing and maintenance intervals provides a useful starting point.

5. NCT, Parking and Tolls

NCTS currently lists a full test at €60 and an equipment-based retest at €40. Certain visual retests are free. Repairs needed to pass are separate from the test fee. Check your vehicle's due date and the latest official NCT fees and guidance.

Parking and tolls depend heavily on your routine. Include workplace parking, regular motorway journeys and any parking permit you need. Small daily charges can become a substantial annual expense.

Depreciation and Finance: Keep the Calculations Separate

Depreciation is the difference between what you pay for a car and what you later sell it for. For example, buying at €12,000 and selling three years later for €7,500 would mean €4,500 in depreciation, or €1,500 per year. This is an illustration, not a resale-value forecast.

Adding that assumed €1,500 annual depreciation to our €4,420 running budget gives an illustrative ownership cost of €5,920 per year, or €493.33 per month, before finance interest and fees.

For cash-flow planning, include your deposit, repayments and any final payment when they fall due. For an economic ownership-cost comparison, use depreciation plus finance interest and fees alongside running costs. Adding full finance repayments and depreciation together would count part of the vehicle cost twice.

Petrol, Diesel, Hybrid or Electric?

Compare each fuel type against your own use rather than assuming one is always cheapest.

• Petrol: compare real-world consumption with the purchase price, insurance and maintenance requirements.
• Diesel: consider your journey lengths and the condition of emissions equipment, particularly if you mainly make short trips.
• Hybrid: check the type of hybrid system, documented maintenance and battery condition. Plug-in hybrids need a realistic charging plan.
• Electric: compare charging access and tariffs, battery condition, insurance, range requirements and likely resale value.

Explore our guides to diesel cars in Ireland and whether hybrid cars are worth buying before narrowing your search.

How to Compare Two Used Cars Fairly

Use the same ownership period and annual mileage for both vehicles. Compare purchase price, expected resale value, insurance quotations, tax, energy costs and known maintenance needs.

A lower asking price can be outweighed by expensive repairs or higher running costs. Equally, paying more for a newer car does not automatically make it cheaper to own.

Before committing, follow our used-car inspection checklist for Ireland and consider an independent mechanical inspection.

Frequently Asked Questions

How much should I budget monthly for a car in Ireland?

Use your own insurance quotation, mileage, tax and maintenance needs. Our worked example allocates €368.33 per month to running expenses and allowances, excluding purchase, depreciation and financing. It is an example budget, not an average or guaranteed cost.

Is the cheapest used car always the cheapest to run?

No. Condition, maintenance due, insurance and fuel consumption can outweigh a lower purchase price. Compare the total expected cost over your intended ownership period.

Should I include depreciation even if I buy without finance?

Yes, when comparing the economic cost of ownership. Depreciation represents lost vehicle value, even though it does not arrive as a monthly bill.

Find a Used Car That Fits Your Whole Budget

Choose a car you can afford to buy, maintain and use. Start with an insurance quotation and realistic mileage, then check tax, service records and upcoming work before deciding.
