Cars and SUVs
Buying a vehicle
Car loan #T779 Work out a car, bike or truck loan payment with trade-in, down payment, sales tax, fees and an optional balloon payment, plus total interest and total cost. Lease or buy #T816 Compare a car lease with a loan purchase over the lease term: what you pay, what you still owe, the car's value left and the net cost of each. On-road price #T890 Turn an ex-showroom or sticker price into the full on-road (out-the-door) price for a car or two-wheeler in India, Canada or the US, itemised, with the loan you need after the down payment. Car depreciation #T894 See the value of a car, two-wheeler or truck after each year with a fixed yearly percent or an editable typical curve, adjusted for the km you drive, with a table, chart and loss per km. Car affordability #T895 Find the most you can spend on a car from your income with the 20/4/10 rule: 20% down, a loan of 4 years at most, and total car costs under 10% of your gross income. All numbers editable. VIN check #T909 Type a 17-character VIN to check its characters and check digit, and read the maker region, the model year and the plant code. Works offline, with no lookups. Used car checklist #T910 A printable used vehicle inspection checklist: papers, body, engine, tyres, interior, test drive and after the drive. Mark OK or Problem, add notes, see a score and red flags, print or save a PDF.
Running costs
EV vs petrol #T814 Compare an electric car, a petrol car and a hybrid over the years you keep it: price, incentives, energy, upkeep, insurance, resale, break-even and rough CO2. Commute cost #T815 Compare what getting to work costs by car, transit pass or bike, in money and in the value of your time. Road trip #T896 Plan a drive from legs with distance and average speed: total time with breaks, fuel stops from your tank size, fuel cost, tolls and the time you will arrive. EV range #T899 Estimate an electric vehicle's real range from battery size and rated consumption, with editable effects for speed, outside temperature, heater or AC and load, plus charging time.
Bikes and scooters
Engine CC #T900 Work out engine size in cc, litres and cubic inches from bore, stroke and number of cylinders, plus compression ratio and the bore to stroke ratio. Sprocket ratio #T901 See your motorcycle's road speed in every gear at a chosen rpm, how much a different front or rear sprocket changes it, and roughly how many chain links you need. Helmet size #T911 Measure your head in cm or inches and see your motorcycle or scooter helmet size, how to measure, how a helmet should fit, and the safety marks to look for.
Trucks and transport
E-way bill validity #T891 Work out how many days an e-way bill is valid for a distance (1 day per 200 km, or per 20 km for over-dimensional cargo), the exact expiry, when you can extend it, and whether you need one. Trip sheet #T892 Fill in a truck trip sheet with freight, advance, diesel fills, tolls, driver bata and loading charges to get km run, km per litre, total cost, profit and the balance due to the driver. Print it or save a PDF. Axle weights #T904 See how a load on a semi-trailer splits between the steer, drive and trailer axles, check each group against US federal limits and the bridge formula, or against Canadian and Indian limits you can edit. Cost per mile #T905 Add up a truck's fixed costs, fuel, maintenance, tyres, tolls and driver pay to get its cost per mile or km, the break-even rate and the rate for a profit margin you choose. Load profit #T906 Enter the rate, loaded and empty distance, your cost per mile, tolls and days to see the profit, the rate per total mile, profit per day and whether the load beats your minimum. Pallet planner #T907 Find how many pallets fit in a 53 ft or 48 ft trailer, or a 20 to 32 ft body, with a top-view drawing, stacking and a weight check against the payload. Fleet fuel #T908 Open a fuel-card CSV on your own device to see each vehicle's fuel economy and cost per km or mile, and flag fills that look wrong: bigger than the tank, too close together, or much worse than usual.
Tyres
Size, age and tread
Tyre pressure #T898 Convert tyre pressure between psi, bar and kPa, see how temperature changes it, and find what to fill to today so the tyre is right on a hotter or colder day. Tyre size #T940 Type the size printed on your tyre, like 205/55 R16 91V, and see in plain words how wide and tall it is, what wheel it fits, how much weight it carries and how fast it is rated, with a picture of each part. Tyre age #T941 Type the 4 digits from the DOT stamp on a tyre to see the week and year it was made, how old it is, and whether it is time to have it checked or replaced. Tread depth #T942 Type your tread depth in mm or 32nds of an inch and see if the tyre is legal, close to the limit or needs replacing, with coin tests and wear-bar checks you can do at home.
Weather and seasons
Fuel
Fuel use and cost
Fuel cost #T752 Work out what a drive will cost in fuel, split it between passengers, and convert fuel economy between L/100 km, km/L, US mpg and UK mpg. Real mileage #T893 Log your fill-ups with the full-tank method and see your real km/L, L/100 km, US and UK mpg, cost per km, a trend chart and the range left in the tank.
Fuel types and blends
Octane guide #T946 Turn RON into AKI and back, see the petrol grades sold in India, the USA, Canada, the UK and the Gulf, and find which fuel your car really needs. Ethanol blend #T947 Work out how much mileage you may lose on E10, E15, E20 or E85 compared with plain petrol, and what each kilometre and each month costs. CNG vs petrol #T948 Compare the running cost per kilometre of petrol and CNG (or LPG), see your monthly saving, and how many months a CNG variant or kit takes to pay for itself. 2-stroke mix #T949 Work out how much 2-stroke oil to add to your petrol for a ratio like 50:1, in ml and fluid ounces, or how much petrol goes with the oil you have.
Driving and safety
Stopping distance #T897 Find reaction distance, braking distance and total stopping distance for a car, two-wheeler or loaded truck on dry, wet, snowy or icy roads, with a bar diagram in car lengths. Hot car #T945 See how hot a parked car gets in the first hour, in sun or shade, with a simple chart and what to do if you see a child or pet inside.
