EV vs Petrol Calculator New York: A Step-by-Step Worked Example

If you want a straight answer on ev vs petrol calculator new york, start with the maths, not a headline figure. This page works through the formula step by step, runs a worked example with every assumption stated in full, and gives you tables you can read your own numbers off. Nothing here is presented as a current price or a measured efficiency: every figure is labelled as an assumption or an example, and the method works with whatever numbers you substitute.

For ev vs petrol calculator new york, the point is this: The short answer is that the comparison comes down to cost per mile: the petrol car burns US gallons, so its cost per mile is the price per gallon divided by its MPG, while the EV uses kilowatt-hours, so its cost per mile is the electricity price per kWh divided by its miles per kWh. With the example assumptions on this page — petrol at $3.45 per US gallon, 38 US MPG, electricity at 28 cents per kWh and 3.5 miles per kWh — the petrol car costs about $0.09 per mile and the EV about $0.08 per mile. Those are example figures, not prices you should quote, and the rest of this page shows how they were reached and what would change them.

ev vs petrol calculator new york: Assumptions used on this page

For ev vs petrol calculator new york, the point is this: Every figure in the tables below comes from this assumptions table. Each one is an assumption or an example, not a measured fact about any particular car or a current price. Substitute your own numbers and the method still works.

Input Value used Status
Petrol price $3.45 per US gallon Example price
Petrol efficiency 38 US MPG Assumption
Electricity price 28 cents per kWh Example price
EV efficiency 3.5 miles per kWh Assumption
Annual mileage 15,000 miles Example

Because this page is about new york, the units above match how drivers there usually measure fuel and electricity. The method itself does not change with location — only the units and the example prices do — so a driver anywhere else can use the same steps with local figures. Do not treat the example prices as current prices for New York: they are placeholders chosen to make the arithmetic easy to follow, and real prices move constantly.

How the EV versus petrol comparison works for ev vs petrol calculator new york

For ev vs petrol calculator new york, the point is this: Hold the mileage constant and price the energy each car actually uses. For the petrol car, cost per mile equals the price per gallon divided by its MPG. For the EV, cost per mile equals the price per kWh divided by its miles per kWh. Multiply each cost per mile by the annual mileage and you have the annual fuel and charging bill for each car; subtract one from the other and you have the saving, or the extra cost, under those assumptions. The method is deliberately simple, because a simple method with honest inputs beats a complicated model built on guessed ones. The two numbers that matter most are the electricity price and the petrol car's MPG: a driver who charges at home on a cheap overnight rate will see a very different answer from a driver who relies on public rapid chargers, and a thirsty petrol car widens the gap while an efficient one narrows it.

Worked example: the same distance, two energy bills for ev vs petrol calculator new york

Take a driver covering 15,000 miles a year. The petrol car does 38 MPG and petrol costs $3.45 per gallon as an example price, so its cost per mile is $3.45 ÷ 38 = $0.09, and 15,000 miles cost $1,361.84 a year. The EV does 3.5 miles per kWh and electricity costs 28 cents per kWh as an example price, so its cost per mile is $0.28 ÷ 3.5 = $0.08, and 15,000 miles cost $1,200.00 a year. The difference on fuel and charging alone is $161.84 a year in the EV’s favour under these assumptions. Now change one input and watch the answer move: if the EV is charged mostly at a public rapid charger at, say, double the home electricity price used here, its annual charging cost doubles and most of the saving disappears. If the petrol car is driven mainly in town at lower MPG, the petrol bill rises and the saving grows. That sensitivity is the real lesson — the answer is only as solid as the assumptions, so write yours down before you believe the result.

ev vs petrol calculator new york: Cost at different annual mileages

On this page, ev vs petrol calculator new york is the case in point: The table uses the worked-example assumptions above — petrol at $3.45 per gallon (example), 38 MPG, electricity at 28 cents per kWh (example), 3.5 miles per kWh. The gap grows with mileage, which is why high-mileage drivers see the biggest fuel-cost difference and low-mileage drivers see the smallest.

Annual miles Petrol cost per year EV charging cost per year Difference
6,000 $544.74 $480.00 $64.74
8,000 $726.32 $640.00 $86.32
10,000 $907.89 $800.00 $107.89
12,000 $1,089.47 $960.00 $129.47
15,000 $1,361.84 $1,200.00 $161.84
20,000 $1,815.79 $1,600.00 $215.79

ev vs petrol calculator new york: Cost per mile and per 100 miles

On this page, ev vs petrol calculator new york is the case in point: At the example assumptions, the petrol car costs $0.09 per mile ($9.08 per 100 miles) and the EV costs $0.08 per mile ($8.00 per 100 miles). Per 100 miles is often the easier figure to compare with a fuel receipt or a charging bill, because both are usually priced in round numbers per hundred miles of driving. If you know your own MPG and your own prices, the same two divisions give your own figures: fuel price per gallon divided by MPG, and electricity price per kWh divided by miles per kWh.

What the comparison leaves out — and why it matters for ev vs petrol calculator new york

The fuel and charging maths on this page is only one slice of the real cost. Left out, by design, are the purchase-price gap between the two cars, depreciation, insurance, servicing, tyre wear and tax — every one of them differs between an EV and a petrol car and every one of them moves the true answer. The page also prices electricity at a single rate, while real life mixes cheap overnight home charging with dear public rapid charging; that mix usually matters more than the headline rate. Price your own mix honestly before deciding which car is cheaper for you. That is the point this page works through for ev vs petrol calculator new york.

Common mistakes for ev vs petrol calculator new york

  • Taking ev vs petrol calculator new york as the case in point: Comparing a car's best-case efficiency with another's everyday figure is another trap. Brochure efficiency is measured in controlled conditions; your real miles per kWh or MPG will be lower, and the comparison only works when both cars are measured the same way.
  • For ev vs petrol calculator new york, the point is this: Forgetting that winter changes EV efficiency is easy to miss. Cold weather reduces an EV's miles per kWh noticeably, so a saving calculated on summer figures will overstate the winter result.
  • For ev vs petrol calculator new york, the point is this: Using the same electricity price for every charge hides the real cost. A driver who mixes home and public charging has two different prices, and averaging them into one number without weighting by how much energy comes from each is a common error.
  • Forgetting charging losses is another: slightly more electricity is drawn from the plug than the battery stores, so dividing the battery size by the miles driven understates the real cost per mile by a few percent. That is the point this page works through for ev vs petrol calculator new york.

Putting your figure to work for ev vs petrol calculator new york

Use the result as a tool, not a verdict. Re-run the two divisions with your own prices and efficiencies whenever they change, and the comparison stays honest. A monthly log — miles, energy used, price paid — is enough to spot the patterns that matter: colder months cost more per mile for an EV, a new charging habit shifts the average, and a petrol car driven more in town drifts the other way. Measured figures beat remembered ones, and the method on this page is built for measured figures. That is the point this page works through for ev vs petrol calculator new york.

Frequently asked questions

Does charging at home really make that much difference?

On this page, ev vs petrol calculator new york is the case in point: Yes, usually more than any other single factor. Home charging is typically far cheaper per kWh than public rapid charging, so a driver who charges at home overnight will see a much bigger saving than one who relies on rapid chargers. Work out your own mix of home and public charging and price each part separately for an honest figure.

What does miles per kWh mean?

On this page, ev vs petrol calculator new york is the case in point: It is the EV equivalent of MPG: how many miles the car travels on one kilowatt-hour of electricity. Higher is more efficient. Divide the electricity price per kWh by miles per kWh to get the EV's cost per mile, in the same way you divide the fuel price per gallon by MPG for a petrol car.

Is an EV always cheaper to run than a petrol car?

For ev vs petrol calculator new york, the point is this: Not always. On fuel and charging alone, an EV is usually cheaper per mile when it charges mostly at home at an example electricity price, but the answer flips if it relies on expensive public rapid charging or if the petrol car is very efficient. Purchase price, depreciation, insurance and servicing are not in the fuel-cost maths, so a full comparison has to include them before calling either car cheaper overall.

What affects an EV's miles per kWh?

Driving speed, temperature, heating and air conditioning, tyre pressures and how much town versus motorway driving you do. Cold weather and high speeds reduce miles per kWh, while gentle town driving usually improves it. Measure yours over several weeks rather than trusting a single trip. That is the point this page works through for ev vs petrol calculator new york.

How sensitive is the saving to the electricity price?

On this page, ev vs petrol calculator new york is the case in point: Very sensitive. Doubling the electricity price doubles the EV's charging cost per mile, while the petrol side is unchanged. That is why this page states its example prices openly: change the electricity price to the one you actually pay and the saving changes with it, sometimes by enough to change the conclusion.
