> The prorated salary calculator works out the salary due for part of a month – for a new starter, a leaver or unpaid leave – from the monthly salary and the working days in that month, accounting for your days off and holidays.

## Inputs

- Month
- Year
- Gross monthly salary
- Days worked
- Approved paid leave days
- Public holidays in the month
- Working week
- Proration basis

## Results

- Days in the month
- Working days in the month
- Daily rate
- Prorated salary

## Formula

```
Working days in the month = days on your working weekdays − public holidays
Daily rate = monthly salary ÷ working days
Prorated salary = daily rate × (days worked + approved paid leave)
```

## Explanation

Employers prorate salaries in different ways – by working days, calendar days or a fixed 30-day month. This calculator counts the actual working days in the chosen month.

### How to use the Prorated Salary Calculator

- **Month**
- **Year**
- **Gross monthly salary**
- **Days worked**
- **Approved paid leave days**
- **Public holidays in the month**
- **Working week**
- **Proration basis**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Choose the month and year, enter the monthly salary, days worked, paid leave and public holidays, and choose your working week.

### Tips

- Tax figures here are estimates for planning – your actual tax depends on credits, deductions and local rules.
- Check the tax year and filing status before you rely on a result.
- Use gross (before-tax) figures unless a field asks for take-home pay.
- When in doubt, confirm with the tax authority's own calculator or a tax professional.

### Common mistakes to avoid

- Confusing marginal and effective tax rates.
- Adding sales tax to a price that already includes it.
- Forgetting payroll taxes (Social Security and Medicare) on wages.

### What each result means

- **Days in the month** = date([Year], [Month] + 1, 1) - [First day]
- **Prorated salary** = min([Daily rate]×([Days worked] + [Approved paid leave days]), [Gross monthly salary])

## Worked example

Inputs — Month: October; Year: 2,026; Gross monthly salary: $6,000; Days worked: 12; Approved paid leave days: 0; Public holidays in the month: 0; Working week: Monday–Friday (5 days); Proration basis: Working days in the month.

Results — Days in the month = 31; Working days in the month = 22; Daily rate = $272.73; **Prorated salary = $3,272.73**.

## FAQ

**How do I prorate a salary?**
Divide the monthly salary by the working days in the month and multiply by the days worked.

**Do weekends count?**
Not when prorating by working days; they do when prorating by calendar days.

**Are public holidays paid?**
Usually yes for salaried staff – they are excluded from working days here.

**What formula does the Prorated Salary Calculator use?**
Working days in the month = days on your working weekdays − public holidays.
