Car Loan Calculator

📖 Tool Introduction

Car finance quotes are deliberately vague. A salesperson quotes a monthly payment of a bit over two thousand and says nothing about total interest or the fees.

This calculator starts from the vehicle price, applies your down payment ratio for the loan amount, then computes the payment and total interest under either equal instalment or a balloon structure, listing purchase tax and insurance separately.

The total outlay figure is the down payment plus every instalment, which is what the car genuinely costs you.

Every figure you type stays inside this browser tab. The arithmetic runs as plain JavaScript on your own device, so nothing is uploaded to a server, nothing survives after you close the page, and there is no account to create or sign in to. You can enter real numbers without worrying about them leaving your machine.

What comes out is a mathematical projection built on the assumptions you supply, and the assumptions are the part worth checking. Real outcomes turn on details no calculator can see: the exact wording of a loan contract, the policy in force in your city this year, the way your own body responds. Use these numbers to orient yourself and to compare one option against another, then confirm anything that carries real consequences against an official document or a professional who can look at your actual circumstances rather than a generic formula. Where a result feeds into a decision that costs money or affects your health, treat it as the opening of a conversation with someone who can see the whole picture rather than as the answer in itself.

The inputs here are deliberately plain: no file to upload, no network call, no queue to wait in. That keeps the tool fast and private, and it also means no record exists anywhere of what you calculated, so nothing you try here can come back to you later.

⚠️ Things to Note

• Extra fees are excluded: This tool excludes finance service fees, GPS fees, registration charges and mandatory accessories, which often raise the real cost substantially
• Estimated purchase tax: Purchase tax is estimated at ten percent of the tax-exclusive price. New energy and some models qualify for reduction or exemption, so check current policy
• The balloon final payment: Balloon loans lower the monthly payment but require a lump sum at the end. Assess whether you can afford it when it falls due
• Computed locally in your browser: Every figure is worked out inside your own browser and nothing is sent to a server. The values disappear when you close the page, so you can safely enter real numbers
• Indicative results only: What you see here is a mathematical projection. For contracts, tax filings or medical decisions, rely on the official documents issued by the relevant authority rather than on this tool
