How we calculate it
- fio cost: active members × US$ 1.99 a month.
- Members who stay: active members × cancellation rate × how much fio lowers it.
- Every member who stays keeps paying their fee: we count 1 ÷ the cancellation rate with fio months, up to 12. With your numbers, 12 months.
- Revenue you keep per month: members who stay × monthly fee × those months. The year is 12 times the month.
- Net gain: revenue you keep minus the cost of fio. It doesn’t add what the custom software or partner businesses bring in.
- In dollars, monthly fees are converted at S/ 3.40 per dollar and rounded to .99.
- Everything is calculated in your browser. We don’t store or send anything.
