Readable tip sheet — not a calculator. When daily overtime, Sunday/special-day, and lump-sum premiums sit inside or outside the regular rate (RR), and whether they credit toward FLSA statutory overtime.

True daily / weekly excess premium (e.g. time-and-a-half after 8 in a day)
Extra pay that is actually contingent on hours over 8 in a day, over 40 in a week, or over the employee’s normal/regular daily or weekly hours can be a true overtime premium.
That extra premium is excludable from the regular rate under FLSA §7(e)(5) and creditable toward statutory overtime under §7(h).
Artificial “straight time then overtime” splits of a normal day (devices to evade the Act) keep the higher rate inside the RR — see also 778.501.
Premiums for work on Saturdays, Sundays, holidays, regular days of rest, or the sixth/seventh day of the workweek can be OT premiums only if the rate is at least time and one-half the bona fide rate for like work on other days.
Qualify → out of RR and creditable. Fail the 1½× test (and not otherwise a 7(e)(5) premium) → in RR, not creditable.
Must be paid because work is on that special day — not, for example, only as a short-notice penalty (that kind of extra usually stays in RR unless another exclusion applies).
Labeling money “OT” or “Sunday premium” is not enough — structure and rate matter.
Hourly premiums tied to excess or special-day hours at true 1½×+ are the ones that usually exit RR and offset statutory OT.
Fixed lumps for “working OT / working Sunday” inflate RR and do not buy OT credit under 778.310.
