E-bike vs car savings calculator
How much would you save by replacing your car commute with an e-bike? Enter your commute, see annual savings, payback period, and 5-year + 10-year net. Sourced defaults from EPA, EIA, Ofgem, and DfT — override anything you know.

How the math works
We compare two scenarios for the same set of commute miles:
Scenario A — keep driving
- Annual fuel cost = miles ÷ mpg × petrol price
- Annual parking = days × parking-per-day × 52
- Maintenance ≈ $0.10/mi (AAA 2024)
- CO2 = fuel × 8.89 kg/gal (petrol) or 10.18 kg/gal (diesel)
Scenario B — switch to e-bike
- Charging cost = round-trips × $0.15/charge
- Maintenance ≈ 15% of car maintenance per equivalent mileage
- CO2 from grid = ebike kWh × regional grid intensity
- Upfront = e-bike cost (one-time, factored into payback period)
Net annual savings = A − B. Payback period = ebike cost ÷ annual savings. 5-year and 10-year nets compound the savings minus the upfront cost.

Savings calculator — FAQ
How much money does an e-bike save vs a car?
A typical 5-mile-one-way commute saves **$1,200–$1,800 per year** in the US (petrol car @ 27 mpg) or **£700–£1,100 per year** in the UK (39 mpg-UK). Fuel is the largest line item; parking adds £/$200–800 in cities. Maintenance saves another £/$300–500. The calculator returns your specific number based on your commute distance + days per week.
What's the typical payback period for an e-bike?
For most US commuters, a $1,500 e-bike pays for itself in **12–18 months**. UK commuters at £1,200 see payback in **14–20 months**. Faster if you have city parking costs or a long commute; slower if you only ride 2–3 days/week or have an efficient EV. Anything under 24 months is industry-standard "good" payback — every month after that is pure savings.
Are e-bikes cheaper than driving in the UK?
Yes — significantly. UK petrol at £1.45/L vs e-bike charging at £0.10 per full charge means **a 5-mile commute costs about £0.20 of fuel by car vs 1p by e-bike**. Over a year of 5-day-a-week commuting, that's £700+ saved on fuel alone. Add UK car insurance (~£600/year), road tax, and parking, and the UK savings beat the US in absolute terms despite smaller absolute fuel cost.
Do e-bikes save money on maintenance?
Yes — significantly. AAA puts US car maintenance at ~$0.10/mile; e-bike maintenance (chain, tyres, brake pads) is roughly **15% of that**. On a 2,600-mile commuting year that's **~$220 saved per year**. UK figures are similar (£0.07/mile car vs ~£0.01/mile e-bike). The catch: if you replace the e-bike battery (every 4–6 years) that's a $300–$700 cost, which the calculator doesn't factor in. Subtract one battery from your 10-year net savings to be safe.
How much CO2 does switching to an e-bike save?
A 2,600-mile commuting year on a 27 mpg car burns ~96 gallons of petrol → **858 kg CO2/year**. The same miles on an e-bike charged from the US grid use ~36 kWh → 13 kg CO2/year. **Net savings: ~845 kg CO2/year**, about the same as planting 14 mature trees per year. UK savings are slightly lower in absolute terms but better in percentage because the UK grid is cleaner.
Is an e-bike worth it for a 5-mile commute?
Almost always yes. A 5-mile-one-way commute (10 mi/day, 50 mi/week, 2,600 mi/year) is the e-bike sweet spot — long enough to make car costs add up, short enough that even a 250 Wh battery handles round trip with capacity to spare. Payback period for a $1,500 e-bike is typically **14–17 months** at this distance. Below 2 miles, the savings shrink because the car costs are smaller; above 8 miles, you'll want a Class 3 (28 mph) bike to keep the trip time competitive.
Does an e-bike save money compared to an EV?
Yes — but the gap is smaller. EVs at 3.5 mi/kWh + $0.16/kWh charging cost about **$0.046 per mile** in fuel. E-bikes at $0.15 per round-trip charge cost about **$0.015 per mile**. So you're still saving ~$0.03/mile, plus the e-bike avoids the EV's **upfront $35,000+ cost**. Over a 2,600-mile commuting year, fuel savings alone are ~$80, but the upfront cost difference means an e-bike is the cheaper choice unless you genuinely need the car for non-commute trips.
