Every calculation runs in your browser, transparently provided based on published rates and formulas.
What Is CarCalc
CarCalc is a free set of tools that help you handle the cost calculations you face at every stage of buying, driving, and selling a car — quickly and clearly. It presents complex acquisition tax structures, loan interest, fuel cost and economy, and used car depreciation alongside their formulas so anyone can understand them.
Operating Principles (E-E-A-T)
- Experience — we mirror the item structure used in real car quotations, loan agreements, and fuel receipts, and break results down item by item.
- Expertise — we calculate based on published rates and formulas, such as 7% passenger acquisition tax (4% for light/commercial), the amortizing loan formula, and fuel cost = distance ÷ economy × price.
- Authoritativeness — we point to official sources such as Wetax and the Vehicle Civil Affairs Portal, with links.
- Trustworthiness — we never hide our formulas and clearly state that every result is an estimate. Your inputs are not collected or stored.
Data Sources
The rates and bases used in each calculator are grounded in the following official sources. Rates may change, and we update to the latest values when they do.
- Wetax — local taxes such as car acquisition tax and vehicle tax
- Vehicle Civil Affairs Portal — vehicle registration and bond guidance
- Opinet — nationwide fuel price information
- Hometax (NTS) — individual consumption tax and VAT
A Note on Accuracy
All CarCalc results are estimates for reference based on your inputs and published formulas. Acquisition tax can change with eco-friendly, multi-child, or disability reductions and local bond differences; loans with handling fees and agreement terms; and depreciation with model, history, and market demand. Always confirm final decisions with an official authority or a professional.
