Calculate Your Real Daily Cost to Drive to Work 2026
Calculate your actual daily commute cost at current fuel prices for short, medium and long distance drives.
Most People Underestimate Their Commute Cost
If you commute by car in Australia right now, you already know it hurts. But do you actually know the number? Most people don't. They estimate by gut feel — "about sixty bucks a week, maybe?" — and they're almost always wrong. With unleaded sitting at $2.60 per litre and diesel above $3.20 in most of the country, the real figure is likely 30 to 50 per cent higher than you think.
This post walks through the proper formula, runs the numbers at today's prices for four common commute types, compares them to what you were paying just six weeks ago, and stacks driving against public transport in Sydney, Melbourne and Brisbane. There's a calculator link at the bottom so you can plug in your own figures.
The Quick Formula Most People Get Wrong
Here's how most people estimate their fuel cost: they remember roughly what a tank costs, divide by how often they fill up, and round to something comfortable. The problem is that this ignores the actual variables — distance, fuel economy, and the price on the day you filled up — and it almost always undershoots.
The correct formula is simple:
**(Round-trip km ÷ 100) × fuel consumption (L/100km) × price per litre × work days per week = weekly fuel cost**
That's it. Four numbers multiplied together. But it's remarkable how few people sit down and do it, which is why most commuters underestimate their weekly fuel spend by 20 to 40 per cent. At today's prices, that gap between perception and reality can be $30 or $40 a week — over $1,500 a year of invisible spending.

Worked Examples at March 2026 Prices
The following examples use today's national average prices: **$2.60/L for Unleaded 91** and **$3.20/L for diesel**. Fuel consumption figures are based on typical real-world averages for each vehicle class (real-world, not manufacturer claims — most cars use 10–20% more than the brochure number). All examples assume a five-day working week.
| Commute Type | Vehicle | Distance | Daily | Weekly | Annual | |---|---|---|---|---|---| | **Short (15km ea way)** | Small hatchback | 30km | **$5.46** | **$27.30** | **$1,420** | | **Medium (35km ea way)** | Mid-size sedan | 70km | **$15.47** | **$77.35** | **$4,022** | | **Long (60km ea way)** | Large SUV | 120km | **$31.20** | **$156.00** | **$8,112** | | **Diesel ute (40km ea way)** | Dual-cab ute | 80km | **$23.04** | **$115.20** | **$5,990** |
:::warning The Diesel Ute Reality Dual-cab utes are Australia's best-selling vehicles (Ford Ranger #1 for 3 years), and owners are hit hard: **high consumption + fuel price >$3/L**. If you're driving a Ranger or HiLux to a job site daily, you're spending almost **$6,000/year** in fuel alone. :::

What Changed Since February
Six weeks ago, before the Strait of Hormuz closure sent global oil markets into a tailspin, the Australian Institute of Petroleum reported national average prices of **$1.73/L for ULP** and **$1.80/L for diesel** for the week ending 22 February 2026. Those feel like numbers from another era.
| Commute Type | Feb 2026 | Now | Increase | |---|---|---|---| | **Short (30km/day)** | $18.27/wk | $27.30/wk | **+$470/yr** | | **Medium (70km/day)** | $51.49/wk | $77.35/wk | **+$1,345/yr** | | **Long (120km/day)** | $103.80/wk | $156.00/wk | **+$2,714/yr** | | **Diesel ute (80km/day)** | $64.80/wk | $115.20/wk | **+$2,621/yr** |
:::danger Cost Shock: February vs March 2026 If you drive a mid-size car 35km each way, you're paying **$1,345 more per year** than February. If you drive a ute, it's **$2,600+ more**. That's a holiday, dental work, or six months of electricity bills. :::

Drive vs Public Transport: The Break-Even
With fuel this expensive, it's worth doing the maths on public transport. The comparison isn't always straightforward — it depends on where you live, where you work, and crucially, whether you have to pay for parking.
**Sydney — Opal Card** The Opal weekly cap sits at **$50 for adults**, unchanged since 2019. At current fuel prices, a medium commute (70km round trip) costs $77.35 per week in fuel alone. Add CBD parking — early bird rates start around $25 to $35 per day, with casual rates pushing $50 to $80 — and driving could easily cost **$200+ per week** to get to a CBD office. The break-even point for fuel cost alone (ignoring parking) is roughly a 40km round trip. Any commute longer than 20km each way, and the train is cheaper on fuel alone. Factor in parking, tolls, rego, insurance, and maintenance, and the gap widens dramatically.
**Melbourne — myki** Melbourne's daily myki cap increased to **$11.40 on weekdays** from 1 January 2026. For a five-day commuter, that's a maximum of **$57 per week**. At $57 per week on myki versus $77.35 per week in fuel for a medium commute (before parking), public transport saves $20 per week — over $1,000 a year. And that's before CBD parking, which runs $20 to $67 per day depending on where you book.
**Brisbane — Go Card (50-Cent Fares)** Brisbane is in a category of its own right now. The Queensland Government made 50-cent flat fares permanent in late 2024, meaning a full working week of commuting — ten trips — costs just **$5.00**. That's not a typo. Five dollars a week for unlimited zones. Even the shortest petrol commute in our examples costs $27.30 a week. A Brisbane commuter switching from car to public transport saves at minimum **$22 per week** on fuel, plus whatever they'd spend on parking. Over a year, that's more than $1,100 in fuel savings alone.
The Parking Multiplier
Parking is the factor most people overlook when comparing driving to public transport. In Australia's three largest CBDs, casual daily parking runs from $36 to $80 or more. Even with an early bird discount, you're looking at $20 to $35 per day. At $25/day over five days, parking alone adds **$125 per week** — $6,500 per year — to your commute cost. Combined with fuel, a medium car commute to a Sydney CBD office can easily exceed **$10,000 per year** in direct costs.

Five Ways to Cut Your Commute Fuel Bill
You can't control the oil price, but you can control how much fuel your commute burns. Here are five things you can do this week:
:::tip 1. Carpool — The Biggest Lever If two people share a 70km round trip, each drops from **$77.35 to $38.68/wk** — **$2,000+/yr savings** each. Three people? **$25.78 each**. FuelCalc has built-in cost-split. Carpooling is the single biggest lever most commuters aren't pulling. :::
:::tip 2. Work From Home One Day Even one day remote cuts weekly fuel bill by **20%**. For medium commute: **$15.47/wk saved = $804/yr**. If flexible arrangements available, use them now. :::
:::tip 3. Switch to E10 (If Compatible) E10 costs **3–5c/L less** than ULP91. At 50L tank: **$1.50–$2.50 saved per fill**. Check your manual for compatibility. See our [E10 vs 91 Unleaded guide](/blog/e10-vs-91-unleaded). :::
:::tip 4. Check Tyre Pressure Underinflateds reduce fuel economy by **3–5%** = **$2–$4 extra/wk**. Two minutes at servo air pump, zero cost. See [driving techniques that save fuel](/blog/driving-techniques-save-fuel) for more tips. :::
:::tip 5. Time Your Fill-Ups Price cycles swing **20–40c/L** between peak and trough. Filling at bottom of cycle on 50L tank saves **$10–$20 per fill**. Check [cheapest day to buy fuel](/blog/cheapest-day-buy-fuel-australia) or [FuelCalc live prices](/wholesale). :::
Track Your Real Costs Over Time
The numbers in this post are snapshots. Fuel prices change daily, your driving habits shift with the seasons, and the crisis may ease — or it may not. We're building a [fuel economy tracker](/economy-tracker) inside FuelCalc so you can log your actual fill-ups, see your real cost per kilometre, and track how your commute cost moves over time.
In the meantime, you can run your numbers right now. [Open the FuelCalc calculator](/) — enter your home and work addresses, select your vehicle, and see your exact daily, weekly and annual commute cost at today's live fuel prices.
