How to Use This Calculator
- Select Your Model: Choose your Tesla model from the dropdown. Each model has different battery capacities which affect total charging costs.
- Set Charge Levels: Enter your starting battery percentage and desired ending percentage. Most drivers charge from 10-20% to 80% for optimal battery health and charging speed.
- Choose Time Period: Off-peak rates apply all day except 4pm-8pm. Peak hours (4pm-8pm) cost approximately 13-15p more per kWh.
- Select Membership: Tesla owners automatically receive discounted rates. Non-Tesla owners can subscribe for £10.99/month to access the same pricing.
- Calculate: Click the button to see your estimated charging cost, energy consumption, range added, and cost per mile.
Optimising Your Charging Sessions
- Charge to 80% rather than 100% for faster charging speeds and better battery longevity
- Avoid peak hours (4pm-8pm) when possible to save 13-15p per kWh
- Pre-condition your battery before arrival for faster charging rates
- Use the Tesla app to check real-time availability and pricing
- Consider home charging for daily use and Superchargers for long journeys
Pricing Structure Explained
Time-Based Pricing
Tesla introduced time-of-use pricing in the UK to manage grid demand. The network operates on a two-tier system:
| Time Period | Hours | Tesla Owner Rate | Non-Tesla PAYG | With Membership |
|---|---|---|---|---|
| Off-Peak | 12am-4pm, 8pm-12am | 39-54p/kWh | 60-67p/kWh | 39-54p/kWh |
| Peak | 4pm-8pm | 52-67p/kWh | 67-79p/kWh | 52-67p/kWh |
Membership Benefits
For non-Tesla EV owners, the £10.99 monthly membership provides access to Tesla owner pricing. This breaks even after charging approximately 73-75 kWh per month, equivalent to one full charge on most long-range models.
Location-Based Variations
Rates differ significantly by location type:
- Motorway Services: Typically 50-67p/kWh (highest rates)
- City Centres: Usually 45-58p/kWh
- Suburban/Rural: Often 33-48p/kWh (best value)
- Destination Chargers: Sometimes free or reduced rates at participating venues
Cost Comparison Analysis
Supercharger vs Home Charging
Whilst Superchargers provide convenience for long journeys, home charging remains significantly cheaper for daily use:
| Charging Method | Rate per kWh | Model 3 LR (0-80%) | Model Y LR (0-80%) | Annual Cost (12,000 miles) |
|---|---|---|---|---|
| Home (Standard Rate) | 25-27p | £16.40 | £17.71 | £810-£950 |
| Home (EV Tariff Off-Peak) | 7-9p | £4.59 | £4.96 | £230-£310 |
| Supercharger (Off-Peak) | 39-54p | £25.74 | £27.79 | £1,270-£1,760 |
| Supercharger (Peak) | 52-67p | £34.32 | £37.04 | £1,690-£2,180 |
| Petrol Equivalent (£1.40/L) | N/A | N/A | N/A | £1,950-£2,350 |
Network Comparison
Tesla’s Supercharger network offers competitive pricing compared to other UK rapid charging networks:
- Tesla Supercharger: 39-67p/kWh depending on time and membership
- Ionity: 69-74p/kWh (members get discounts)
- BP Pulse: 44-79p/kWh depending on charger speed
- Gridserve: 66-79p/kWh at motorway hubs
- Pod Point: 40-65p/kWh (varies by location)
Battery Capacity by Model
| Model | Battery Capacity | EPA Range | Efficiency (miles/kWh) | 0-80% Charge Cost (Off-Peak) |
|---|---|---|---|---|
| Model 3 Standard Range | 60 kWh | 272 miles | 4.5 | £23.52 |
| Model 3 Long Range | 75 kWh | 358 miles | 4.8 | £29.40 |
| Model 3 Performance | 82 kWh | 315 miles | 3.8 | £32.15 |
| Model Y Standard Range | 60 kWh | 260 miles | 4.3 | £23.52 |
| Model Y Long Range | 82 kWh | 331 miles | 4.0 | £32.15 |
| Model Y Performance | 82 kWh | 319 miles | 3.9 | £32.15 |
| Model S | 100 kWh | 405 miles | 4.1 | £39.20 |
| Model X | 100 kWh | 348 miles | 3.5 | £39.20 |
Efficiency figures represent real-world averages. Actual consumption varies based on driving style, weather, terrain, and speed.
Frequently Asked Questions
Maximising Charging Efficiency
Pre-Conditioning Strategy
Pre-conditioning your battery before arriving at a Supercharger significantly improves charging speeds:
- Set Supercharger as destination in navigation to automatically warm the battery
- Pre-conditioning can improve charging speed by 25-40% in cold weather
- Optimal charging occurs when battery temperature reaches 20-25°C
- Allow 15-20 minutes pre-conditioning time for best results
Optimal State of Charge
Charging speed varies dramatically based on battery percentage:
- 10-50%: Maximum charging speed (150-250 kW depending on charger)
- 50-70%: Speed begins tapering (100-150 kW)
- 70-80%: Significantly reduced speed (50-100 kW)
- 80-100%: Very slow charging (25-50 kW) – not recommended
Cost Saving Strategies
- Route Planning: Choose cheaper suburban Superchargers over motorway services when practical
- Timing: Avoid peak hours (4pm-8pm) to save 13-15p per kWh
- Charge Level: Stop at 80% rather than 100% for faster sessions and lower costs
- Membership: Subscribe if charging 75+ kWh monthly at Superchargers
- Home Priority: Use cheap overnight home charging (7-9p/kWh) for daily driving
- Price Checking: Compare nearby stations in the Tesla app before selecting
Real-World Cost Examples
Scenario 1: Weekly Commuter
Profile: 150 miles weekly commute, charges at home
- Weekly consumption: 35 kWh (Model 3 LR)
- Home charging (7p/kWh overnight): £2.45/week = £127/year
- Supercharger equivalent (49p/kWh): £17.15/week = £891/year
- Annual savings with home charging: £764
Scenario 2: Monthly Long-Distance Driver
Profile: 500 miles monthly motorway driving, uses Superchargers
- Monthly consumption: 125 kWh (Model Y LR)
- Without membership (65p/kWh peak): £81.25/month
- With membership (52p/kWh peak): £65 + £10.99 = £75.99/month
- Monthly saving with membership: £5.26 (£63/year)
Scenario 3: Frequent Business Traveller
Profile: 1,000 miles monthly, mix of motorway and home charging
- 700 miles home charged: 146 kWh × 7p = £10.22
- 300 miles Supercharged: 63 kWh × 49p = £30.87
- Total monthly cost: £41.09
- Petrol equivalent (35 mpg, £1.40/L): £176.45
- Monthly saving vs petrol: £135.36 (£1,624/year)
