Travel costs and timing are set by rules that are easy to miss until they cost you money at the airport. A checked bag seven pounds over the limit, a tip calculated with the wrong custom, or a photo that fails a visa spec can all derail a trip that was otherwise planned well. These calculators keep the numbers straight before you leave.

Baggage and timing

Most US airlines allow a checked bag up to 50 lb, but the budget carriers use 40 lb. Go over and the fee is steep: a 57 lb suitcase on Delta is 7 lb over, which lands in the 51 to 70 lb tier and adds $100 on top of the normal bag fee. That is $135 each way. Seven pounds is about a pair of sneakers, jeans, a hoodie and a toiletry bag, which you can often move into a carry-on. On the day of the flight, the check-in tool works backward from your departure time to tell you when to leave, when bag drop closes and when boarding starts.

• Flight time: the tool estimates hours and minutes from the distance between two airports and a cruise speed you pick.
• Tips abroad: the calculator splits a bill, converts to US dollars and shows local tipping customs by country.
• Visa photos: the US wants a square 2 by 2 inch photo, while much of the world uses 35 by 45 mm.
• Budget: add flights, lodging, food and a buffer to see the total per person and per day.

Confirm current fees and limits with your airline, since they change often.
