Question 1

How do you calculate total cost of car ownership?

Accepted Answer

Total cost of ownership (TCO) includes: purchase price, loan interest/financing costs, fuel or electricity costs based on annual mileage and efficiency, routine maintenance and servicing, insurance premiums, registration and road taxes, depreciation, and country-specific charges like RUC (New Zealand), VED (UK), or state taxes. Our calculator computes these costs year-by-year over 1-20 years of ownership.

Question 2

Is an electric car cheaper to own than petrol?

Accepted Answer

Electric vehicles (EVs) typically have higher upfront costs but lower running costs. EVs save money through: cheaper electricity vs petrol/gas, reduced maintenance (no oil changes, fewer brake replacements), tax incentives and rebates, and lower road tax in many countries. The break-even point depends on annual mileage, local electricity rates, and fuel prices. Most EV owners see savings within 3-7 years for high-mileage drivers.

Question 3

What countries does CostMyCar support?

Accepted Answer

CostMyCar provides vehicle cost calculators for 11 countries: New Zealand (with RUC), Australia (with stamp duty), USA (with federal tax credits), United Kingdom (with VED and MOT), Canada (with iZEV rebates), India (with FAME subsidies), Germany, France, Netherlands, Norway (highest EV adoption), and Spain. Each calculator uses country-specific costs, taxes, and incentives.

Question 4

How accurate is the vehicle cost calculator?

Accepted Answer

Our calculator uses current market data for fuel prices, electricity rates, insurance averages, and depreciation rates. Accuracy depends on the inputs you provide. For best results, enter your actual vehicle specs, local fuel/electricity costs from recent bills, and real insurance quotes. Default values are updated regularly to reflect market conditions.

Question 5

Should I buy a hybrid or fully electric car?

Accepted Answer

The choice depends on your driving patterns. EVs are ideal for: daily commutes under 200km, access to home charging, and high annual mileage (15,000+ km). Hybrids suit: long-distance drivers, those without home charging, and areas with limited EV infrastructure. Use our calculator to compare 5-10 year costs for your specific situation.

Question 6

How does car depreciation affect total ownership cost?

Accepted Answer

Depreciation is often the largest single cost of car ownership, typically 15-20% in year one and 10-15% annually thereafter. A $40,000 vehicle could lose $18,000 in value over five years — more than fuel and insurance combined. EVs historically depreciated faster due to rapid battery improvements, though this is improving as second-hand EV demand grows. Our calculator tracks depreciation for each vehicle type so you see the true net cost difference between EV, hybrid, and petrol options.

Question 7

What additional costs are not included in basic car cost calculators?

Accepted Answer

Beyond fuel and insurance, experienced car owners budget for: tyres ($600-1,200 per set every 20,000-30,000km), brake pad replacements (more frequent for EVs due to regenerative braking), windscreen replacement ($300-800), roadside assistance membership, parking fees and tolls (particularly in cities like Sydney, London, and Singapore), car wash and detailing, and contingency for unexpected mechanical failures. Our running cost calculator factors in these variable costs to give you a realistic annual figure.

Question 8

Should I finance my car with a loan or pay cash upfront?

Accepted Answer

Paying cash eliminates interest costs — a $30,000 loan at 7% over 5 years costs an extra $5,500 in interest. However, some financing deals offer 0% interest or you may be able to invest the cash at a higher return. Our calculator lets you compare both scenarios by adjusting the loan interest rate. For high-net-worth individuals, keeping cash invested and financing may be mathematically advantageous. For most people, paying cash upfront is the simpler, cheaper option.

Question 9

Which country has the cheapest total cost of EV ownership?

Accepted Answer

Norway currently offers the lowest EV ownership costs globally, thanks to VAT exemptions, reduced registration taxes, free public parking and charging, and reduced ferry fares. A Tesla Model 3 in Norway costs roughly half what it does in the UK or Australia once all incentives are applied. In New Zealand, EV ownership is about 40% cheaper than petrol long-term when accounting for RUC, fuel savings, and maintenance. Use our country comparison calculator to compare costs across all 11 supported nations.

Question 10

How much does car insurance cost for EVs compared to petrol vehicles?

Accepted Answer

EV insurance premiums are typically 10-20% higher than equivalent petrol vehicles due to the higher repair costs of specialised EV components and battery systems. However, this is partially offset by lower comprehensive insurance rates as more insurers enter the EV market. In the UK, EV drivers pay an average of £100 more per year. Our calculator uses country-specific insurance data — enter your quoted premium to see how it affects your total ownership cost over 5-10 years.

Question 11

Is EV maintenance really cheaper than petrol or hybrid maintenance?

Accepted Answer

Yes — EVs have significantly lower maintenance costs because they have no internal combustion engine, meaning no oil changes, timing belt replacements, exhaust repairs, or complex transmission servicing. Estimates suggest EV maintenance costs are 50-70% lower per kilometre than petrol vehicles. Brake wear is also reduced thanks to regenerative braking. The main ongoing EV costs are tyre replacements and 12V battery checks. Our total cost calculator factors in these differences so you can see the genuine long-term savings.

Question 12

What does it cost to install home EV charging?

Accepted Answer

Home charging installation costs vary by country: Australia $800-2,500 AUD, UK £800-1,500, USA $700-2,000 USD, and New Zealand $1,200-2,500 NZD. Standard Level 1 (120V) charging uses a regular socket but adds only 40-50km range per hour. Level 2 (240V) fast charging requires a dedicated circuit and adds 50-80km per hour. Despite the upfront cost, home charging is the cheapest way to run an EV — costing approximately $0.03-0.06 per kilometre vs $0.12-0.18 for petrol. Our calculator includes home charging installation in the total cost analysis.

Question 13

How do government EV tax credits and rebates affect the total cost?

Accepted Answer

Government incentives vary dramatically by country and can shave thousands off the purchase price. USA federal tax credit offers up to $7,500 for qualifying EVs. Canada iZEV provides $5,000 CAD. India FAME III subsidies reach up to ₹150,000. Germany's environmental bonus ended in 2023, reducing EV appeal there. New Zealand's Clean Car Discount was $8,625 for EVs before ending. These incentives can shift the break-even point between EV and petrol ownership forward by 2-4 years. Our calculator incorporates current incentive levels for each country.

Question 14

Should I buy a used EV instead of a new one to reduce ownership cost?

Accepted Answer

Buying a 2-3 year old used EV can save you 30-40% off the new car price while still having most of the battery life and software features. Battery degradation in modern EVs is minimal — most retain 90%+ capacity after 100,000km. However, used EV prices are elevated relative to the overall used car market due to high demand. A 3-year-old Tesla Model 3 may only save you $8,000-12,000 vs new. Our cost calculator lets you compare scenarios for both new and used vehicle purchases to see which offers better long-term value.
