EV buying tools

Keep my car or buy a Tesla?

Adjust the example for your car to see what switching costs, what you could save and when the extra expense may pay back.

Use what you could sell your car for today, not what you originally paid. Fuel is estimated from consumption and site prices. Uncheck that option to enter actual fuel bills for the same period as your kilometres; include all trips.

Figures and sources

Equal weight per report; at least 1,600 km per owner. Wh/km ÷ 10; Wh/mi ÷ 16.09344. Single trips and repeated reports are excluded. Parked use, such as Sentry Mode, is extra.

Insurance, road fees and Tesla servicing use editable site budgets. Your current car uses the recorded servicing and repair average, or your separate budget. Future resale is separate from payback.

Charging availability

AC use is limited by available power and parked time. Any energy it cannot supply moves to DC. New scenarios use 10 hours overnight and up to 3.7 kW at home; imported charging settings stay unchanged.

Where these estimates come from

Starting budgets assume a used car in normal condition. Purchase prices are editable examples, not current listings. Warranty eligibility is not verified.

Insurance
Bulstrad 2026 full Casco: 4.94% for Highland/Juniper and S/X starters (assumed up to 3 years old), 5.75% for original Model 3/Y and fuel cars (assumed over 3–5 years), plus 2% premium tax. These ages are starter assumptions. Liability uses the Sofia tariff for a private owner aged 30–78, including tax and fund contributions. Confirm eligibility, age, cover and repair network with an insurer. Annual premiums stay constant in this estimate.
Servicing and tyres
Service budgets combine Bulgarian labour prices with separate allowances for parts, tyres and wear. AT Batsalov lists oil/filter labour at €23.30 including VAT; parts cost extra. Tesla intervals set the filter and brake checks. The budget includes two seasonal changes of four tyres; oil service for fuel cars is assumed annually or every 15,000 km. Check your car’s schedule. Major repairs are separate.
Tax, inspection and road fees
Annual vignette: €64.50 from BG TOLL. Inspection: €46.02 from one Sofia M1 station, budgeted once a year. EV vehicle tax: €0. Combustion example: €62.74 in Sofia, 110 kW, Euro 6, up to 5 years old. Other municipalities, ages and power differ. Set unused items to 0. Parking, transfer and registration costs are separate; today’s annual costs are held constant.
Resale value
The base resale budget keeps 50% of today’s value after another 5 years and 25% after 10. Lower-cost and higher-cost scenarios vary these values by 30%. Bulgarian listings are asking prices, not completed sales or a future depreciation curve, so they do not set this forecast. Enter your own expected sale price in the advanced settings.
