Formula Used
Future car price = Current price × (1 + inflation rate)years.
Future total cost = Future car price + sales tax + registration fees + dealer fees + insurance reserve.
Net target cost = Future total cost − trade-in value − rebate.
Goal amount = Net target cost for full purchase, or net target cost × down payment percentage for a deposit goal.
Future value of current savings = Present savings × (1 + periodic rate)periods.
Future value of monthly deposits uses the ordinary annuity formula: Payment × [((1 + monthly rate)months − 1) ÷ monthly rate].
Required monthly saving = Remaining future funding need ÷ annuity factor.

Frequently Asked Questions
1. What does this calculator estimate?
It estimates how much you may need for a future car purchase, then compares that target with your projected savings growth.
2. Why include inflation?
Vehicle prices often rise over time. Inflation helps you save toward a more realistic future purchase cost.
3. Should I save for the whole car or only the down payment?
Use full purchase if you want to avoid financing. Use down payment if you plan to finance the remaining amount.
4. What return rate should I use?
Use a conservative rate that matches your savings or investment account. Higher assumptions can overstate future balances.
5. Does trade-in value reduce the goal?
Yes. A trade-in or rebate lowers the amount you must fund from savings.
6. What does required monthly saving mean?
It shows the monthly deposit needed to hit your chosen goal within the selected timeline and return assumptions.
7. Can I export the results?
Yes. You can download the schedule as CSV or use the PDF button to save a print-ready version.
