Calculators

Count your days, in your browser.

These calculators run the same rules engine as the app, validated against the same golden test fixtures. They run entirely client-side: nothing you enter is transmitted, stored or seen by us.

US

Physical presence test calculator (FEIE)

Check the FEIE physical presence test: full days abroad, the best 12-month window, how many days you are short, and the earliest date you could qualify.

IN

Residential status calculator (India)

Work out your Indian residential status: Resident, RNOR or Non-resident, with the limb that decided it and how far you are from the next threshold.

SCHENGEN

Schengen 90/180 calculator

Check your Schengen short-stay allowance: days used, days remaining, the date you would breach the limit, and the next day a day frees up.

UK

Statutory Residence Test calculator (UK SRT)

Work through the UK Statutory Residence Test in order: automatic overseas tests, automatic UK tests, then sufficient ties, with the deeming rule applied.

US

Substantial Presence Test calculator

Work out whether you meet the IRS Substantial Presence Test: the three-year weighted count, days remaining, and your latest safe departure date.
