Small purchases, big totals

A coffee here, a takeaway there — each small purchase feels tiny on its own, which is exactly why they add up unnoticed. Pick your categories, enter roughly how many you buy per week and what each one costs, and see the real total per month and per year, in the currency you actually spend in.

It answers questions like 'how much do I spend on coffee a month', 'what do my snacks and takeaway really cost per year' and 'how much do small everyday purchases add up to' — the classic latte factor, calculated instantly. And because money is really time, it links you straight to what those totals mean in working hours.

Good to know

  • A $5 coffee every workday is about $110 a month and $1,300 a year.
  • Four $12 takeaways a week is roughly $210 a month — about $2,500 a year.
  • Skipping just one $4 purchase a week saves about $17 a month and $208 a year.
