Transparent by design

A clearer picture starts here.

Review the example inputs, then calculate. We show the assumptions alongside your result.

Why is this an estimate?

Resale value is your scenario, not a market forecast. The separate loan payment is a cash-flow figure. No balloon, arrangement fees or early-settlement costs are modelled.

Read our methodology

EVVerity estimates are informational and are not a substitute for a professional battery diagnostic or pre-purchase vehicle inspection.

See how the calculation works

Economic cost = depreciation + interest paid during ownership + running costs. Loan principal is not added to depreciation.

Resale value is your scenario, not a market forecast. The separate loan payment is a cash-flow figure. No balloon, arrangement fees or early-settlement costs are modelled.

Separate ownership cost from the monthly loan payment

Depreciation is purchase price minus your assumed resale value over the ownership period. The tool adds finance interest and operating expenses. It does not add the loan principal again to depreciation, because that would count the same purchase cost twice.

Where to get useful inputs

  • Enter insurance, tax and maintenance amounts for a full year.
  • Use your actual finance terms; this is a simplified amortising-loan calculation, not a lender quotation.
  • Try more than one resale assumption. It is an estimate you supply, not a market valuation.
Why is monthly ownership cost different from cash paid this month?

Ownership cost spreads depreciation and the relevant expenses across the ownership period. Cash flow also depends on deposits, repayments and when bills fall due. Read the separate finance figures and the stated model limitations.

Methodology, assumptions & confidence →

See why resale assumptions can outweigh energy savings

Original EVVerity worked scenario. Inputs are illustrative, not measured vehicle results or market prices.

  1. Use purchase price 18,000, deposit 18,000, APR 0, term 60 months, ownership 5 years and resale 8,000. Depreciation is 2,000 per year.
  2. For 12,000 km per year, consumption 18, loss 10% and tariff 0.25, energy is 600 per year. Insurance 700 and service 300 bring the subtotal to 3,600 per year, or 300 per month, with tax, tyres and parking set to 0 solely for this example.
  3. Reduce resale to 5,000: annual depreciation rises by 600 and the monthly subtotal by 50. Add your actual omitted costs before using either result.

What the result helps you decide

Resale is a scenario you supply. The tool does not value the vehicle. A 50-per-month difference caused by resale can matter as much as a change in electricity price; compare both.
