Enter the rate you were quoted or found for your specific transaction — exchange rates move constantly and differ between banks, cards, and cash exchanges, so there's no single "correct" rate to default to.

Minimum connection times vary by airport — this uses common industry planning minimums (45–60 min domestic, 75–120 min international depending on re-check) as a general guide, not an airport-specific guarantee.

Eastward travel is generally harder to adjust to than westward travel, because it shortens your day rather than lengthening it — this is reflected in the different day-per-zone estimates used below.

Lodging is a total per night (not per person); food and local transport are per person per day; flight cost is round trip, total for all travelers. This compares trip costs only — add visa and insurance costs separately if they differ between destinations.

These percentages are illustrative planning estimates, not a quote — real US travel insurance typically runs roughly 4-10% of trip cost depending on provider, coverage, traveler age and pre-existing conditions. Always compare actual quotes from licensed insurers before you buy.

This is an illustrative planning estimate only, not the official minimum. Proof-of-funds requirements vary by embassy or consulate, change over time, and often depend on whether lodging is already prepaid — always confirm the current, exact requirement with the specific embassy or consulate you're applying through.

Emission factors are widely-used averages (grams CO2 per passenger-km): short-haul flight economy ~150g, long-haul flight economy ~115g, long-haul business/first ~260g, train ~35g, car (whole vehicle) ~170g, coach/bus ~30g, ferry ~115g. Real figures vary by aircraft, occupancy, grid mix and vehicle efficiency — treat this as a planning estimate, not a certified carbon audit.

A plan whose data allowance is below your total expected usage is flagged as insufficient, even if its cost per GB looks attractive — you'd need to add a top-up, which changes the real cost.

Driving time here is pure travel time at your average speed — it doesn't include the rest stops themselves, so add roughly 15-20 minutes per stop to your real departure-to-arrival time.

A commonly cited baseline is that many travel points/miles are worth somewhere around 1-1.5 cents each when redeemed reasonably well — this varies enormously by program, so set your own target based on what you've seen that program's points redeem for.

These are general regional norms, not rules — always check the bill for an already-included service charge (common across much of Europe and the Middle East) before adding an extra tip, and use local judgement for taxis, hotels and tours, which often differ from restaurant norms.

The "183-day rule" is a widely-used general rule of thumb, not a universal law — many countries use a rolling 12-month window instead of a calendar year, count partial days differently, or apply entirely different tests (e.g. centre-of-vital-interests, permanent home, citizenship). Tax residency can also be triggered well below 183 days in some countries. This tool is a starting point for awareness only — always get advice from a qualified tax professional for your specific situation.

All figures are monthly totals in your own currency, for one person. This is meant for comparing a base to live and work from for weeks or months, distinct from the short-trip destination comparison tool above — visa, tax residency and health insurance costs are not included here and should be checked separately.

UTC offsets can include half-hour or 45-minute steps (e.g. UTC+5.5 for India, UTC+9.5 for Central Australia) — enter these as decimals. This ignores daylight saving changes; re-check offsets around DST transitions.
