概要

Gas Mileage Calculatorとは

Owning a vehicle in India involves more ongoing math than most buyers anticipate at the showroom. Road tax varies by state, insurance renewals go up each year, fuel prices shift weekly, and depreciation quietly erodes resale value in the background. The Gas Mileage Calculator puts the specific numbers in front of you using Indian-market defaults - the kind a generic international calculator would miss entirely.

Use the Gas Mileage Calculator to budget before buying, run a periodic cost check during ownership, or plan a road trip. For business-use vehicles where you're claiming expenses against tax, use the calculator's output as a starting figure and have your CA confirm what's deductible under the current rules - that part changes more often than the depreciation math does.

使い方

Gas Mileage Calculatorの使い方（3ステップ）

  1. Enter the distance driven and the fuel used.

  2. Choose your units.

  3. Read mpg (US and UK), km/l and l/100 km.

計算式

Gas Mileage Calculatorのしくみ

Fuel economy divides distance by fuel. Consumption (l/100 km) is the inverse, expressed per 100 km.

Formula

mpg = miles / gallons | l/100km = 100 x litres / km

計算の仕組み

Gas Mileage Calculatorが結果を出す方法

The Gas Mileage Calculator uses Indian-specific defaults wherever relevant: petrol, diesel and CNG prices in major Indian cities, RTO rules for road tax, average vehicle insurance premiums, and standard fuel-economy figures published by ARAI.

Costs are estimates. Fuel prices change daily and vary by city; insurance premiums depend on the vehicle's IDV, your location and your claim history; depreciation curves differ by brand and segment. Use the Gas Mileage Calculator as a directional input and refine with quotes from dealers, insurers or fleet operators.

活用場面

Gas Mileage Calculatorを使う場面

  • Buyers comparing the all-in cost of two vehicles before making a purchase decision.
  • Existing owners deciding when to sell or replace based on rising running costs.
  • Trip planners estimating fuel and toll costs before a road trip.
  • Fleet managers budgeting periodic maintenance and replacement cycles for a vehicle pool.
注意

よくある間違いと落とし穴

  • Using a city's average fuel price for trip planning across multiple states. Diesel and petrol prices can vary by ₹3-5 per litre across states.
  • Forgetting taxes and insurance in total ownership cost. Road tax (5-12%) and 5-year insurance can together add 10-15% to vehicle on-road price.
  • Ignoring depreciation. A ₹15 lakh new car is worth ₹8-9 lakh after 5 years - that's roughly ₹1-1.4 lakh of depreciation per year, often more than fuel.
  • Comparing only EMI between vehicle loan options. Down-payment, processing fee and total interest matter more than monthly EMI alone.
プロのコツ

このツールを使いこなす

  • Always factor depreciation into your ownership cost - it's typically the biggest line item over 5+ years.
  • Compare on-road price (not ex-showroom) when shopping. The difference is 10-20% and varies by state.
  • Pair this calculator with the EMI and fuel-cost calculators for a complete picture of vehicle ownership economics.
  • Re-run the trip-cost calculation periodically as fuel prices change - the same trip can cost 10% more or less month to month.
FAQ

Gas Mileage Calculatorに関するよくある質問

Why do US and UK mpg differ?

The UK (imperial) gallon is about 20% larger than the US gallon.

What is a good figure?

Around 15 km/l (6.7 l/100 km) is efficient for a petrol car.

Total cost of ownership, simplified

Owning a vehicle in India means juggling EMI, fuel cost, depreciation, charging cost (for EVs), maintenance and trip cost. These numbers are interconnected - a longer commute means more fuel, faster depreciation, and bigger interest payments. Rather than treat them in isolation, the vehicle calculators help you see the full stack before you sign on the dotted line.

Pair this calculator with the EMI, depreciation, fuel cost and EV charging calculators to compute the realistic monthly cost of ownership. For depreciation we follow the IRDAI standard schedule used by Indian insurers for IDV (Insured Declared Value); for EV charging we model losses, charger type and time-of-use tariffs.
