About this tool
Calculate the true cost of owning a car — EMI, fuel with inflation, insurance, maintenance and depreciation — and compare it against taking taxis.
Car Ownership Cost Analyzer works out what a car costs you per month, per kilometre and across 1, 3, 5 and 10 years by adding four blocks together: the loan EMI, running costs (fuel, insurance, maintenance, parking, tolls), one-off charges like registration and accessories, and depreciation — the purchase price minus what the car is worth when you sell it. It is built for Indian buyers deciding between a purchase and staying with cabs. The EMI uses the standard reducing-balance formula, EMI = P × r × (1+r)^n / ((1+r)^n − 1), and fuel is compounded forward each year at the inflation rate you enter.
Open Car Ownership Cost Analyzer on AltFTool — it loads instantly in your browser.
On the Basic tab enter Purchase Price, Down Payment, Interest Rate and Monthly Income — the Loan Amount field fills in on its own.
Use the Fuel and Expenses tabs to set Mileage, Fuel/Energy Price, Insurance/Year, Ownership Period (years) and Resale Value After Ownership as a percentage.
Read the 5-Year Cost of Ownership, Depreciation and Budget Compatibility bands, then the Buy vs Uber/Ola table; Reset Analyzer clears everything.
Most calculators stop at EMI plus fuel; this one charges the price-minus-resale gap over your ownership period, which is usually the single largest cost.
Year 2's fuel bill is year 1's grown by your inflation rate, so a 10-year projection does not quietly assume today's pump price forever.
Cab cost is projected over the same 1, 3, 5 and 10-year horizons and the tool names the first year at which owning wins, or says it never does.
With the standard reducing-balance formula: EMI = P × r × (1+r)^n / ((1+r)^n − 1), where P is the loan amount, r is the annual rate divided by 12 and by 100, and n is the tenure in months. On ₹8,00,000 at 9% for 5 years that is ₹16,607 a month, and ₹1,96,401 of interest across the 60 instalments.
This tool flags under 15% of monthly take-home pay as comfortable and 15-25% as manageable; above 25% it warns. Those bands are a little wider than the well-known 20/4/10 rule (20% down, 4-year loan, all car costs under 10% of gross income) because the figure here already includes fuel, tolls and parking, which the 10% rule usually leaves out.
Yes. Enter the resale value as a percentage of the purchase price and the ownership period, and the tool charges the difference across those years. A ₹10,00,000 car worth 40% after 5 years depreciates ₹6,00,000 — about ₹10,000 a month, which is often more than the fuel bill.
It depends almost entirely on distance. Below roughly 500 km a month cabs nearly always win, because EMI, insurance and depreciation run whether you drive or not. The tool projects both sides over 1, 3, 5 and 10 years and reports the first horizon at which total ownership cost, depreciation included, falls below the cab bill.
