Money gets awkward on the road
Booking the flight is the easy part. The awkward bits come later: converting prices in your head at a market stall, working out who owes whom after a week in a rented villa, deciding if 60,000 miles for a ticket is a deal or a rip-off.
The four tools here handle those moments. They run in your browser and your trip details stay private.
Currency converter
The converter uses live mid-market exchange rates, the same ones banks trade at. That's not what you get as a tourist. Banks, card networks and exchange booths add a spread on top, and the tool estimates that spread so you can see the real cost.
Type an amount, pick two currencies and read the result. It also shows the inverse rate and the money lost to the spread. Rates are cached for an hour to keep the page fast, so for a large transfer check the live quote with your provider.
A few habits save real money. If a card terminal asks whether you want to pay in your home currency or the local one, choose the local one. The home-currency option usually carries a poor rate. Avoid airport exchange counters. Withdraw modest amounts from bank ATMs. And find a card with no foreign transaction fee before you leave.
Travel cost splitter
Group trips go sour over money more often than over anything else. One person pays for the house, another for dinners, a third for the car. By day six no one remembers who paid what.
The splitter handles up to eight travelers and many expenses. You can weight shares, for example when a couple shares a room and a solo traveler doesn't. Expenses can be entered in different currencies with your own rates. The tool calculates each person's balance and suggests a short list of payments to settle everything with the fewest transfers. A copy button creates a summary you can paste into the group chat.
Tips for peace: enter expenses as you go, not at the end. Agree on the split rules before the trip. And settle up within a week of getting home.
Frequent flyer mile value
Miles aren't money until you spend them. The mile value calculator divides the cash price of a ticket, minus any taxes and fees you still pay, by the miles needed. That gives cents per mile, or CPM.
It compares the result with a benchmark for the program and gives a verdict. As a rough guide, anything well above about 1.5 cents per mile is decent for many programs, and below 1 cent usually means pay cash. The tool also shows the break-even cash price, the point where using miles makes sense.
Remember that points and miles have an opportunity cost. If you could have earned 2 percent back in cash on the same spending, factor that in. And don't hoard. Miles can lose value when programs change their charts, and some expire.
Bill splitter
For dinners with friends. Choose equal, itemized or custom splits. Enter tax and tip and the tool adds them proportionally, handles rounding and produces Venmo-style payment lines.
Itemized is the fair option when one person ordered a salad and another ordered steak and wine. Equal is simpler when everyone ordered about the same. Apply tip on the pre-tax total or after-tax total depending on local custom. Customs differ by country, and in some places service is already included.
Before you go
Make a rough budget with the converter, using the exchange rate you expect. Tell your bank you're traveling so cards aren't blocked. Carry some local cash for small shops and taxis. Keep a backup card in a separate place.
Check entry rules and travel insurance well before departure. These tools help with math, not paperwork.
A trip budget, line by line
Say you're spending ten days abroad. Flights 700, lodging 90 a night for nine nights, food 40 a day, transport 15 a day and activities 250. That's 700 plus 810 plus 400 plus 150 plus 250, so 2,310. Add 10 percent for the things nobody plans for, and you're near 2,540.
Now convert it. If the local currency moves 3 percent against yours between booking and travel, your budget moves about 70. Not a disaster, though worth knowing. Use the converter with a slightly worse rate than today's so you have a cushion.
Splitting the shared costs early keeps the trip friendly. Decide who pays the big items and settle once, not daily.
Cards, cash and fees
Fees hide in three places: the exchange rate margin, the foreign transaction fee and the ATM fee. A card with 3 percent on foreign spending turns a 2,000 trip into 60 extra. A bad ATM can charge a flat fee plus its own rate.
Carry two cards from different networks, one main and one backup, plus a little cash. Withdraw larger amounts less often if your bank charges per withdrawal. And always choose to pay in the local currency.
Miles and points in context
Points feel free, but they have a price. If a flight costs 450 in cash or 30,000 miles plus 40 in taxes, your miles are worth about 1.4 cents each. That's fair, and not exceptional. If you can fly for 12,000 miles when cash is 400, you're looking at over 3 cents, which is a real deal.
Use the mile value tool before you spend. And try not to sit on a pile of miles for years.
