Formula Used
Taxable amount = price + destination fee + order fee + dealer fee - trade-in value.
Sales tax = taxable amount × sales tax rate.
Gross out-the-door cost = price + fees + sales tax + registration.
Loan amount = gross cost - incentives - trade-in - down payment.
Monthly payment = L × [r(1 + r)n] ÷ [(1 + r)n - 1].
Annual charging cost = miles × Wh per mile ÷ 1000 × charging loss factor × electricity rate.
Net ownership cost = total vehicle, finance, energy, insurance, maintenance, tire, parking, and toll costs minus incentives, trade-in, and resale value.
Cost per mile = net ownership cost ÷ total miles driven.

Model 3 Cost Planning Guide
Why Total Cost Matters
A Model 3 cost estimate should include more than the sticker price. The final number may change after taxes, fees, loan interest, charging, insurance, and resale value. This calculator gathers those items in one place. It helps you compare purchase price with long term ownership cost. It also shows monthly pressure on your budget.
Purchase Cost Details
Start with the vehicle price. Then add destination, order, dealer, and registration fees. Sales tax can be large, so it should not be ignored. Incentives reduce your net cost. Trade value can also lower the amount you finance. A larger down payment can reduce interest and monthly payment.
Financing and Interest
The loan section estimates a standard fixed payment. It uses APR, loan term, and financed balance. A longer term can lower the monthly payment. Yet it may increase total interest. A shorter term may cost more each month. It can save interest over the life of the loan.
Charging and Daily Use
Electric driving cost depends on miles, efficiency, electricity price, and charging loss. The calculator converts watt hours per mile into yearly kilowatt hours. It then multiplies energy use by your electricity rate. This gives annual and monthly charging cost. Enter your local rate for better accuracy.
Ownership Expenses
Insurance, tires, maintenance, tolls, and parking can affect the final result. These costs are often missed during quick comparisons. The calculator spreads them across the ownership period. It also subtracts estimated resale value. This gives a clearer net ownership cost.
Better Budget Decisions
Use several scenarios before buying. Try different APRs, terms, mileage levels, and resale values. Compare a low down payment with a larger one. Check how home charging setup changes the first year. Review the cost per mile. This figure helps compare the car with other transport choices.
FAQs
What does this Model 3 calculator estimate?
It estimates purchase cost, loan payment, charging cost, ownership expenses, resale impact, monthly cost, and cost per mile.
Can I include incentives?
Yes. Enter any eligible incentive or credit amount. The calculator subtracts it from the ownership cost.
Does trade-in value reduce the loan?
Yes. Trade-in value is subtracted before estimating the financed amount. Local tax rules may vary.
How is monthly loan payment calculated?
It uses the standard amortized loan formula with loan amount, monthly interest rate, and term length.
How is charging cost calculated?
It uses yearly miles, efficiency, charging loss, and electricity price. The result shows yearly and monthly charging cost.
Can I use another currency?
Yes. Change the currency symbol field. The math stays the same for any currency.
Why include resale value?
Resale value reduces the net ownership cost. It helps estimate what the car may truly cost over time.
Are the example values official prices?
No. They are sample values for testing. Always enter your own quote, tax rate, fees, and local energy price.
