Am I double-counting an EV’s purchase price and loan payments?
Cash-flow budgeting and economic ownership cost answer different questions. Mixing them can count the same purchase more than once.

A closer look
Choose the question first
For monthly affordability, list cash actually leaving the account: deposit timing, loan instalments, energy and other bills. For economic ownership cost, depreciation and financing costs are useful. Keep the two views separate instead of adding every line from both.
Separate principal from interest
Loan principal repays the purchase amount; interest is a financing expense. If a model already includes purchase price minus resale value as depreciation, adding principal repayment again overstates economic cost. Interest and relevant finance fees can still belong in that model.
Use a simple illustration
A hypothetical car bought for 25,000 and sold for 18,000 has a 7,000 purchase-to-sale difference before other costs. Counting that 7,000 and the entire 25,000 of principal repayments as separate economic losses would duplicate part of the purchase.
Keep future resale uncertain
A resale assumption is not a guaranteed market value. Test a lower resale scenario and distinguish it from an actual offer. Where a finance agreement contains a final payment or conditions, use the actual contract figures rather than assuming all agreements behave alike.
