Useful next steps
One basis for every plan
Each price is multiplied by its charges per year: 52 for weekly, 26 for every two weeks, 24 for twice a month, 12 for monthly and 1 for yearly. These period counts match the pay period table in IRS Publication 15-T (2026). A 12.00 weekly gym plan costs 624.00 a year and 52.00 a month. Change the weeks per year to 52.1775 and the days per year to 365.2425 if you prefer an average Gregorian year.
Rounding and trials
Each plan is rounded to the currency decimal places first, and totals add the rounded plans, so the table always adds up. A yearly plan shows its monthly equivalent, for example 99.99 a year is 8.33 a month. First-year cost removes free trial months as twelfths of the yearly cost; it does not follow exact billing dates, price changes or taxes.
