Pro Rata Salary Calculator (Gibraltar)

How pro rata salary is worked out

1. 1

   Enter your full-time salary

   Start with the annual salary paid for a full-time role at your normal contracted hours.

2. 2

   Add the full-time hours

   Enter the standard full-time working week for the role, typically 40 hours in Gibraltar.

3. 3

   Add the hours you actually work

   Enter the hours you are contracted to work each week, which will usually be lower than full-time hours.

4. 4

   Get your pro rata pay

   The calculator multiplies your full-time salary by your hours ratio to show your pro rata annual, monthly and weekly pay.

The pro rata salary formula

Pro rata annual salary = Full-time salary x (Hours actually worked / Full-time hours)

• •If you only worked part of the year, multiply the result again by (Months worked / 12).
• •The monthly equivalent is the pro rata annual salary divided by 12.
• •The weekly equivalent is the pro rata annual salary divided by 52.
• •This is a gross figure - tax and social insurance contributions are calculated separately.

Worked example

An employee on a £30,000 full-time salary based on a 40-hour week works 24 hours a week for the full year.

Working 24 of 40 hours a week (60% of full-time) gives a pro rata annual salary that is 60% of the full-time £30,000 salary.

When pro rata salary applies

Part-time contracts

Anyone working fewer hours than the standard full-time week for their role is normally paid pro rata.

Starting or leaving mid-year

If you join or leave partway through the year, your salary for that period is usually pro rated by the months or weeks worked.

Job-share arrangements

Job-share employees typically each receive a pro rata share of the full-time salary based on their agreed hours.

Career breaks and reduced hours

Employees who temporarily reduce their hours, for example after parental leave, are usually paid pro rata for the reduced hours agreed with their employer.

Frequently Asked Questions

What does pro rata salary mean?

Pro rata salary means your pay is calculated in proportion to how many hours you work compared with a full-time employee doing the same role, so someone working half the hours of a full-time colleague is typically paid half the full-time salary.

How do I calculate my pro rata salary in Gibraltar?

Divide the hours you actually work each week by the standard full-time hours for the role, then multiply that ratio by the full-time annual salary to get your pro rata annual pay, which you can then divide by 12 or 52 for monthly or weekly figures.

Does pro rata salary include tax?

No, the pro rata salary figure produced by this calculator is a gross amount before income tax, social insurance contributions and any other deductions are applied, so your take-home pay will be lower.

Do part-time employees get the same benefits as full-time staff?

Part-time employees are generally entitled to the same type of benefits as full-time colleagues, such as holiday entitlement, but many of these benefits are themselves calculated pro rata based on hours worked.

What if I only work part of the year?

If you start, leave, or take unpaid leave partway through the year, your annual pro rata salary can be reduced further by multiplying it by the proportion of the year actually worked, based on months or weeks.
