8,000 miles/year at 4 miles/kWh = 2,000 kWh. At 7p/kWh off-peak (typical overnight EV tariff): 140/year to charge. Same mileage in a 40 MPG petrol at 1.50/L = 1,363/year. Home charging is often 10× cheaper than equivalent petrol.
Quick example
With annual miles of 8,000 and efficiency of 4 (plus off-peak rate of 0.07), the result is 140.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Annual Miles, Efficiency (miles/kWh), and Off-peak Rate (per kWh). Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
When to actually change the habit
Most lifestyle spending delivers real value. The exceptions are the ones that stopped delivering months ago but got auto-renewed anyway, and the ones chosen out of defaults rather than preference. Run this, then audit for those two categories — that's where the easy wins live.
What this doesn't capture
The tool prices the money; it can't weigh the enjoyment. A coffee habit, gym membership, or streaming bundle might cost what the math says but deliver value that's harder to quantify. Use the number to make the trade-off visible — the decision is yours.
Where to go next
This calculation rarely sits alone in a planning exercise. If you're running these numbers, you'll probably also want the car insurance annual increase calculator, the car maintenance annual cost calculator, and the ev charging cost per mile calculator — each one answers a different question in the same territory. Treating them as a set rather than in isolation usually produces a more honest picture.
