What It Does

Three steps to the real fuel cost of a job

Enter how the job will actually run and the calculator does the maths. No spreadsheet, no round number guessed at the end of the quote.

1

Job details

How long the job runs and how many days a week the crew's on site.

2

Your exact vehicles

Pick the make and model of each vehicle on the job. Fuel use comes from a built-in database, so there's no hunting for specs.

3

Addresses and fuel

Enter the depot and site addresses and it works out the distance. Then add trips per day, fuel type and today's price.

Your result

The fuel cost for the whole job, ready to drop into your quote.

Who It's For

For project trades with crews on the road

If your crew drives to the same site every day for weeks, fuel is a real cost on every job, whether you're working across town or well out past it. Built for Kiwi builders and project trades who want it priced in, not guessed.

Why It's Useful
Quote with confidence when prices move

Use today's pump price, not the one from six months ago.

Stop margin leaking on long jobs

A few dollars a day across a three-month build adds up fast.

Price far-away jobs properly

The Formula

How to work out fuel cost for a job

Multiply the total kilometres by your vehicle's fuel use, then by the price per litre. Do it for each vehicle and add them up.

(km per trip × trips per day × days) × (L/100km ÷ 100) × $ per litre
1

Get the return distance. Depot or home to site and back. The calculator does this from the two addresses.

2

Count the trips. Include supplier runs, tip runs and the extra trip back for the thing you forgot.

3

Use your real fuel use. Loaded utes and towing burn more than the brochure figure. On diesel, remember Road User Charges come on top of the pump price.

Worked example

Two utes on a 15-day deck build, 60 km round trip, one trip a day, 9 L/100km, diesel at $2.00/L. Road User Charges not included.

2 × 60 km × 15 days1,800 km
1,800 km × 0.09 L/km162 L
162 L × $2.00$324
With 10% markup$356.40
Why It Matters

Where fuel quietly eats your margin

Fuel's easy to overlook until prices jump. These are the trips that usually miss the quote.

Supplier runs

The mid-job trip to the yard for more timber or fixings.

Tip runs and green waste

Loaded trips burn more and often go the long way round.

Machine fuel on site

Diggers, bobcats, compactors and generators all need filling.

Return visits

Defects, inspections and handover add trips after the main work's done.

Next Step

Fuel is one line. NextMinute keeps the whole job on track.

Quote from templates so travel and fuel never get left off, schedule the crew so you're not doubling up trips, and track actual vs quoted by job and stage while the work's still underway.

Fuel cost questions from Kiwi tradies

We’ve answered the ones we hear most from Kiwi builders and tradies.

What's the easiest way to work out fuel costs for a job in NZ?

The easiest way is to let the calculator do it. Pick your vehicles, pop in your yard and the job site address, and add how long the job runs. It works out the kilometres, litres and dollar cost for the whole job. Doing it by hand is fine for one ute, but it gets messy fast with a few vehicles and extra trips. Then drop the figure into your quote in NextMinute's quoting software.

Do I need to include Road User Charges when quoting diesel travel?

Yes, if your utes or trucks run on diesel. Road User Charges are paid per kilometre on top of the pump price, so a diesel ute on a long job costs more to run than the fuel bill alone suggests. The calculator gives you the fuel cost, so add RUC for the same kilometres before you price travel. It's an easy one to miss on jobs out of town.

Does the calculator work for petrol and diesel vehicles?

Yep, it works for both. Choose the fuel type and enter today's price per litre, and the calculator uses the fuel figures for your exact make and model. That matters because a petrol van and a diesel ute can burn quite differently on the same run. If you're running a mixed fleet, add each vehicle separately so the total reflects what's actually heading to site.

How much does it cost to run a ute to site each day?

It depends on the distance and the vehicle, which is why it's worth running the numbers. A ute doing a 60 km round trip at 9 L/100km uses about 5.4 litres a day. At $2.00 a litre that's around $11 a day before Road User Charges. Over a three-month build that adds up to a real line on the quote, so don't leave it to a guess.

Should I charge travel time as well as fuel?

Plenty of trades do, because time behind the wheel is time the crew isn't building. Fuel covers the vehicle, travel time covers the people. On a job an hour out of town, the travel time can be worth more than the fuel. Track hours against the job with timesheets so you can see what travel really costs you over a few jobs.

How do I price jobs out of town or in rural areas?

Work out the full travel cost before you price the job, not after. Run the fuel numbers for every vehicle, add Road User Charges on diesel, and allow for travel time and the odd extra trip. Rural and out-of-town jobs are where travel most often eats the margin. If the job needs the crew to stay away, factor accommodation in as well.

Can I use the calculator for a crew with several vehicles?

Yes. Add each vehicle heading to the job, like a couple of utes and a truck, and the calculator works out the fuel for each one and gives you the total. That's handy for builds where different vehicles come and go. When you're ready to plan who's on which job and when, NextMinute's scheduling helps you avoid doubling up trips.

How do I stop fuel costs blowing out my margin?

Price it properly up front, then keep an eye on it while the job runs. The calculator sorts the first part. For the second, NextMinute's job costing shows actual costs against your estimate by job and stage, so if travel and fuel start running over you'll know while there's still time to do something about it.

Can I add the fuel cost straight into my quotes?

Yes. Copy the figure into your quote as a travel or fuel line, or save a travel line in your quote templates so it's there by default. Once the quote's accepted and invoiced, NextMinute syncs with Xero and other accounting software, so you're not keying the same numbers in twice.

Is NextMinute worth it for a small building crew?

If you've got a crew of three or more running multi-day jobs, it's worth a look. NextMinute puts quoting, scheduling, timesheets and job costing in one place, so costs like fuel stop slipping through the cracks. Have a look at the plans in NZD, or give it a crack with a free trial.
