Partial pay periods
How prorated salary works in 2026
When you work only part of a pay period — because you started mid-month, left mid-month, or took unpaid leave — your employer prorates your salary to pay you for the days you actually worked. The standard method divides your annual salary by the total work days in the year, then multiplies by the days you worked in that period.
The proration formula
Prorated pay = (Annual salary / Annual work days) x Days worked. An employee earning $78,000 per year with a 260-day year has a daily rate of $300. If they start on the 15th and work 12 of the 22 work days in the month, their prorated check is $300 x 12 = $3,600 gross, compared to a full-month check of $6,600.
| Annual salary | Daily rate (260 days) | 12 days worked | Full month (22 days) |
|---|---|---|---|
| $50,000 | $192.31 | $2,308 | $4,231 |
| $65,000 | $250.00 | $3,000 | $5,500 |
| $78,000 | $300.00 | $3,600 | $6,600 |
| $100,000 | $384.62 | $4,615 | $8,462 |

When proration applies
Salary proration is most common when starting a new job mid-period, resigning or being terminated mid-period, returning from or starting unpaid leave (FMLA, sabbatical), or transitioning between part-time and full-time status. It does not apply during paid leave — PTO, sick days, and paid holidays are counted as worked days for pay purposes.
Tax impact of a prorated paycheck
A smaller prorated check means less tax withheld from that particular paycheck, but your annual tax liability is based on your total income for the year. If you started mid-year, your actual annual income is lower than your salary rate, which may result in an over-withholding correction at filing time.

Questions
Prorated salary calculator FAQ
How is prorated salary calculated?
The most common method is the work-day approach: divide your annual salary by the total work days in the year (typically 260 or 261) to get a daily rate, then multiply by the number of days you actually worked. For example, a $78,000 salary divided by 260 days equals $300 per day. If you worked 12 days in a partial month, your prorated pay is $3,600.
What number of work days should I use?
Most employers use 260 work days (52 weeks times 5 days). Some use 261 or 262 depending on how the calendar year falls. The federal government uses 2,087 hours (approximately 261.25 days) as the annual divisor. Check with your HR department to confirm which divisor your employer uses, as it slightly affects the daily rate.
Does prorated salary include benefits?
Prorated salary only covers base pay. Benefits like health insurance, retirement contributions, and PTO accrual are prorated separately according to your employer's benefits policies. Some benefits begin on day one, others after a waiting period, and PTO typically accrues proportionally based on the fraction of the year worked.
When is salary prorated?
Salary is prorated whenever a salaried employee works a partial pay period. The most common situations are starting a new job mid-period, leaving a job mid-period, taking unpaid leave during a pay period, or transitioning from part-time to full-time (or vice versa) during a period.
Is prorated pay taxed differently?
No. Prorated pay is taxed just like regular pay — federal income tax is withheld based on your W-4 and annualized income, and FICA applies (6.2% SS up to $184,500 and 1.45% Medicare in 2026). A smaller paycheck may fall into a lower withholding bracket for that period, but your year-end tax liability is based on total annual income.
