Travel calculators
5 free tools
Before you pack, do the math. Price out the drive, budget the whole trip, sort out who's awake when across time zones, and get a feel for how rough the jet lag will be. A few minutes here saves a lot of guessing later.
Add up fuel, lodging, and food for a road trip, then split the total across everyone sharing the car.
Turn a time in one city into the local time in one or more others, so a call never lands at 3 a.m. for someone.
Total up flights, lodging, daily food, activities, and a buffer to see your full trip budget and daily average.
Estimate rough recovery days from the zones you cross and the direction you fly, with tips to adjust faster.
Enter any two of distance, speed, and time to solve the third, with unit selectors for miles, km, mph, and more.
Frequently asked questions
Which travel calculator should I start with?
Depends on the trip. Driving somewhere? The Road Trip Cost Calculator sizes up fuel and hotels. Flying? Start with the Travel Budget Planner, then use the Time Zone Converter to book calls and the Jet Lag Calculator to plan your first day.
How accurate is the time zone converter?
It reads your browser's own time zone data, so daylight saving shifts are handled for you. The one thing to double-check is the date — a late-night conversion can land on tomorrow somewhere, and the result shows the weekday so you catch that.
Are the trip cost numbers exact?
Treat them as solid estimates. Gas prices swing, hotels add taxes and fees, and a splurge dinner can blow past your daily food figure. Pad the total a little and you'll rarely be caught short.
Is the jet lag estimate reliable?
It's a rule-of-thumb, not a medical prediction. Recovery runs about a day per zone, a bit slower flying east, but sleep, age, and your flight all matter. Use the number to plan a light first day, not to schedule to the hour.
