South Dakota workers benefit from a state minimum wage that is well above the federal floor: $11.20 per hour as of January 1, 2025 — $3.95 more per hour than the federal rate of $7.25 set by the Fair Labor Standards Act (FLSA). This calculator converts that hourly rate into the numbers that matter for day-to-day planning: weekly gross pay, monthly gross and annual gross salary, with FLSA overtime built in automatically whenever you work more than 40 hours in a week.
How it works
Enter your hourly wage (pre-filled with the South Dakota 2025 minimum of $11.20) and your average hours per week. The calculator splits your hours into two categories:
- Regular time — the first 40 hours at your straight-time rate.
- Overtime — every hour beyond 40 at 1.5 times your regular rate, as required by FLSA Section 7(a)(1). South Dakota has no separate state overtime law; the federal 40-hour weekly threshold is the only trigger.
Weekly gross = (regular hours x wage) + (overtime hours x wage x 1.5).
Monthly gross is derived as weekly x 52 / 12, capturing the exact calendar average. Annual gross is weekly x 52. All arithmetic runs entirely in your browser — nothing is uploaded or stored anywhere.
A warning badge appears if you enter a wage below $11.20 (South Dakota state minimum) or below $7.25 (federal minimum), so you can spot non-compliant scenarios instantly. A second panel compares your entered wage against the South Dakota minimum and the federal $7.25 rate side-by-side on an annual basis.
Worked example
Suppose you work 45 hours per week at the South Dakota minimum of $11.20 per hour:
| Metric | Calculation | Result |
|---|---|---|
| Regular pay | 40h x $11.20 | $448.00 |
| Overtime pay | 5h x $16.80 (1.5x) | $84.00 |
| Weekly gross | $448.00 + $84.00 | $532.00 |
| Monthly gross | $532.00 x 52 / 12 | $2,305.33 |
| Annual gross | $532.00 x 52 | $27,664.00 |
At a straight 40 hours per week with no overtime, South Dakota minimum wage produces a weekly gross of $448.00, a monthly gross of $1,941.33, and an annual gross of $23,296.00 — before federal income tax, Social Security (6.2%) or Medicare (1.45%). South Dakota is one of nine states with no state income tax, so workers keep a larger share of gross earnings than in most other states.
Compare that to a worker paid the federal minimum of $7.25/hr for 40 hours/week: their annual gross is just $15,080. The South Dakota minimum wage generates $8,216 more per year at standard hours — a 54% premium over the federal floor.
South Dakota minimum wage in context
South Dakota voters approved Amendment E in November 2014, creating a CPI-indexed state minimum wage codified at SDCL 60-11-3.1. The amendment established an initial minimum wage of $8.50 per hour on January 1, 2015 — well above the then-federal rate of $7.25 — and required it to be adjusted each January 1 in proportion to any increase in the CPI-U for the Midwest urban region, published by the U.S. Bureau of Labor Statistics. The rate can never fall below the previous year’s figure.
The 2025 rate of $11.20 reflects approximately a decade of cumulative CPI adjustments on top of the original $8.50 rate. The South Dakota Department of Labor and Regulation publishes the new rate each autumn for employers to plan accordingly.
Tipped workers receive special treatment under SDCL 60-11-3.3: employers may pay a direct cash wage as low as $5.60/hr in 2025 (50% of the state minimum), provided that tips bring the effective hourly rate to at least $11.20 in every workweek. If tips fall short, the employer must top up the difference.
Youth minimum wage: SDCL 60-11-3.2 permits a sub-minimum rate for employees under 18 during their first 90 days of employment — currently $10.08/hr (90% of the state minimum). After 90 days or on the employee’s 18th birthday, the full $11.20 floor applies.
No state income tax: South Dakota is one of nine U.S. states that levies no individual income tax. This means take-home pay is higher relative to gross pay than in most states. Workers still pay federal income tax, Social Security (6.2%) and Medicare (1.45%).
Use this calculator to model any hourly rate scenario — for instance, how a prospective $14/hr, $16/hr or $18/hr job offer translates into annual earnings — so you can compare job offers, negotiate a pay rise, or stress-test a household budget with confidence.
