How does FLSA 778.303 retroactive pay work?

A retroactive increase of X per hour raises the regular rate for the retro period. The employee is owed X for each hour worked plus an extra half of X for each overtime hour (the CFR example: 10 cents per hour means 15 cents for each overtime hour). A lump-sum retro for a period is prorated over the hours of that period the same way § 778.209 allocates a bonus.

Same as 778.209 bonus inclusion?

778.303 points to the 778.209 method for lump-sum retros. This page is specifically about retroactive pay increases (hourly or lump) that reopen the regular rate for a past period — not production / percentage / discretionary bonus pages.

Same as 778.120 deferred commissions?

No. 778.120 allocates deferred commissions that cannot be tied to particular workweeks. 778.303 applies a pay-rate increase (or lump) backward over hours already worked.

If an employee is awarded a retroactive increase of 10 cents per hour, he is owed under the Act a retroactive increase of 15 cents for each overtime hour worked during the period. On five 10h @ $20 that is +$5.50 → total $1,105.50.

FLSA 778.303 Retroactive Pay Increases — Hourly / Lump

Q: Classic $20 × five 10h + $0.50/h?

New rate $20.50. Pay = 50 × $20.50 + ½ × $20.50 × 10 OT = $1,025 + $102.50 = $1,127.50. Retro additional over the original $1,100 is $27.50 ($0.50 × 50 + $0.25 × 10). vs /overtime/ $1,100 without the increase.

FLSA 778.303 retroactive pay increases — hourly / lump

29 CFR § 778.303 (lump method via § 778.209): a retroactive pay increase raises the regular rate for the period of its retroactivity. Hourly: owed increase×hours + ½×increase×OT hours (CFR: 10¢/h → 15¢ per OT hour). Lump: prorate over hours of the period. Classic $20 × five 10h + $0.50/h → $1,127.50 vs /overtime/ $1,100 vs CFR 10¢ $1,105.50 vs lump $70 $1,177 vs 778.120 $1,205.60 vs 778.310 $1,182.50 vs 778.302 $1,650.

How 778.303 pays

Hourly retro. An award of X dollars (or cents) per hour for a past period increases the regular rate by X. Straight-time hours pick up X; each overtime hour picks up X plus an extra half of X — the regulation’s 10¢ → 15¢-per-OT-hour example.

Lump retro. A lump sum for a particular period is prorated back over the hours of that period to find the increase in the regular rate, “in precisely the same manner as a lump sum bonus” (§ 778.209). Additional overtime is one-half of that cents-per-hour increase times overtime hours.

Not 778.120 / not waiting-time / not a separate 778.209 page. 778.120 allocates deferred commissions. This page reopens the rate (or adds a lump) for hours already worked. Percentage / discretionary / gift / profit-sharing bonus pages stay on their own statutes.

Classic · $20 × five 10h + $0.50/h → $1,127.50 (new RR $20.50; extra $102.50; retro add $27.50).
CFR · +10¢/h on the same week → $1,105.50 (+15¢ × 10 OT = +$1.50 of the $5.50 add).
Lump · $70 over 50h → RR $21.40 → $1,177 (add $77).
Zero retro · five 10h @ $20 → $1,100.
+$1.00/h · five 10h → $1,155 (same $ as 778.116 board, different statute — not this page’s classic).

Hourly vs lump?

Hourly applies a flat cents-per-hour increase to every hour (plus half on OT). Lump divides the award by hours in the period first, then applies that increase — the § 778.209 method § 778.303 incorporates by reference.

Same as /flsa-778-120-deferred-commission/?

No. 778.120 allocates deferred commissions across weeks/hours. 778.303 reopens the wage rate (or adds a lump) for a past period.

Why not ship 778.209 itself?

778.209 is the general bonus-inclusion method already referenced by several bonus pages. 778.303 is the commercial formula for retroactive pay increases with the CFR’s 10¢/15¢ example.

Can parties agree to skip the OT premium on the increase?

No. Section 778.303 says the employee is owed the 1.5× increase on overtime hours “no matter what the agreement of the parties may be.”
