Vehicle & Travel Calculators
Work out what your car really costs to buy and run — on-road price, fuel and EV charging.
Updated June 2026 · Free · No sign-up
Owning and running a vehicle in India involves a lot more than the ex-showroom price you see in the brochure. Once you add RTO road tax, registration, insurance and handling charges, the on-road price can jump well beyond the sticker, and that gap changes from one state to the next. This cluster brings together the numbers every car and bike owner keeps reaching for, from the On-Road Price calculator that builds up the true cost state by state to the Fuel Cost Trip calculator that tells you what a long drive will set you back.
Beyond the purchase, the running costs are where the real money goes month after month. Use the EV Charging Cost calculator to compare a home top-up against public AC and DC fast chargers and see the saving over petrol or diesel, or the Fuel Cost Trip calculator to plan a road trip down to the cost per km. For the hands-on owner, the Tyre Size and Horsepower calculators help you decode P-metric tyre markings and convert between HP, kW and PS when you are comparing variants.
All Vehicle & Travel Calculators
On-Road Price Calculator
Estimate on-road price of a new car = ex-showroom price + RTO road tax (state-wise) + registration fee + insurance (TP + OD + add-ons) + handling charges. Supports all 28 states/UTs and fuel types (petrol/diesel/EV/CNG).
Fuel Cost Trip Calculator
Calculate fuel cost for any trip — enter distance, vehicle mileage, fuel type (petrol/diesel/CNG/EV), and city. Shows total fuel needed, total cost, cost per km, and EV-vs-ICE comparison.
EV Charging Cost Calculator
Calculate cost to charge your electric vehicle at home (₹6-10/kWh slab tariff) vs public AC slow (₹8-15/kWh) vs DC fast (₹18-25/kWh). Returns full-charge cost, cost per km, and savings vs petrol/diesel equivalent.
Tire Size Calculator
Calculate tire diameter, sidewall height, and compare tire sizes from P-metric notation.
Horsepower Calculator
Calculate horsepower from torque and RPM, or convert between HP, kW, and PS.
Frequently asked questions
What is the difference between ex-showroom and on-road price?
Ex-showroom price is the manufacturer's price plus GST and cess, before any registration or insurance. On-road price adds RTO road tax, registration fees, the insurance premium (third-party plus own-damage and any add-ons) and dealer handling charges. Because road tax is set by each state, the on-road price for the same car varies noticeably between states.
How is road tax on a car calculated in India?
Road tax is levied by your state RTO and is usually charged as a percentage of the vehicle's ex-showroom price or invoice value. The exact slab depends on the state, the price band, and often the fuel type, with many states offering lower rates or exemptions for electric vehicles. It is generally paid once at registration as a lifetime tax for private vehicles.
Is it cheaper to run an electric car than a petrol car in India?
Per kilometre, charging an EV at home is almost always cheaper than petrol or diesel, since home electricity at roughly Rs 6 to 10 per kWh works out to a far lower running cost than fuel. Public DC fast charging at Rs 18 to 25 per kWh narrows the gap but is usually still cheaper than petrol. The EV Charging Cost calculator shows the per-km cost for each option so you can compare directly.
What does a tyre size like 195/55 R16 mean?
The first number (195) is the tyre's width in millimetres, and the second (55) is the aspect ratio, meaning the sidewall height is 55% of the width. The R denotes radial construction, and 16 is the wheel rim diameter in inches. The Tyre Size calculator uses these values to work out the overall diameter and sidewall height so you can compare sizes safely.
