Age-Based Accrual

The Age-Based Accrual plugin grants additional time off based on employee age. This is commonly used for “senior days” where older employees receive extra vacation days, often mandated by collective agreements or company policy.

When to use

Use this plugin when:

Older employees receive additional vacation days
Your collective agreement grants extra days based on age
You need flexible age-based calculations using formulas
Different age brackets have different entitlements

Parameters

Parameter	Description	Required
Days per year formula	Expression to calculate days per year. Can use the `age` variable. See Formula examples.	Yes
From age	Minimum age for eligibility. Employees turning this age during the year qualify.	Yes
To age	Maximum age for eligibility (optional). Leave at 0 for no upper limit.	No
Max days	Maximum days per year cap. Set to 0 for no limit.	No
Accrual method	When accruals occur: yearly at year start, yearly on birthday, or monthly.	Yes
Year start month	Which month starts the accrual year.	Yes
Prorate by working hours	When turned on, part-time employees receive proportionally fewer days based on their FTE.	No

Accrual methods

Yearly at start of year

Grants the full amount on the first day of the vacation year. The employee’s age at that date determines eligibility and the formula result.

Best for: Simple annual grants tied to the vacation year.

Yearly on birthday

Grants the full amount on the employee’s birthday. The accrual uses their new age for the formula calculation.

Best for: Benefits that activate when the employee reaches a specific age.

Monthly

Distributes the annual amount across 12 monthly accruals. Eligibility is checked each month.

Best for: Gradual accrual throughout the year, similar to regular vacation.

Every 2 Months

Distributes the annual amount across 6 bimonthly accruals (January, March, May, July, September, November based on year start). Eligibility is checked at each period.

Best for: Less frequent accrual while still spreading benefits throughout the year.

Every 3 Months (Quarterly)

Distributes the annual amount across 4 quarterly accruals. Eligibility is checked at each quarter.

Best for: Quarterly grants that align with business quarters or review cycles.

Formula examples

The formula field accepts mathematical expressions using the age variable.

Fixed amount

For a simple fixed number of days regardless of age:

All eligible employees receive 5 days.

Linear increase

For one additional day per year of age above a threshold:

age - 60

Age	Days
60	0 (not eligible if from_age > 60)
61	1
62	2
65	5

Progressive formula

For more complex calculations:

(age - 60) / 2

Age	Days
62	1
64	2
66	3

With maximum cap

Combine a formula with the Max days parameter:

Formula: age - 60
Max days: 5

This limits the benefit to 5 days maximum, even for employees 66+.

How it works

The plugin evaluates eligibility and calculates accruals based on employee age:

Eligibility check: Employee must be between From age and To age
Age determination: Age is calculated at the accrual date
Formula evaluation: The formula is evaluated with the employee’s age
Capping: Result is limited by Max days if set
Proration: FTE proration is applied if enabled
Crediting: Amount is added to the time bank account

Age eligibility

An employee is eligible if they turn the minimum age at any point during the accrual year:

From age: 62
Year start: September
Employee born October 15, 1963
In September 2025, they are 61 but turn 62 in October
They are eligible for the September 2025 - August 2026 accrual year

Examples

Danish senior days (Seniordag)

Many Danish collective agreements grant 1 extra day per year from age 60:

Add the Age-Based Accrual plugin
Set Days per year formula to age - 59
Set From age to 60
Set Max days to 5 (common cap)
Set Accrual method to Yearly at start of year
Set Year start month to September

Result:

Age 60: 1 day
Age 61: 2 days
Age 62: 3 days
Age 63: 4 days
Age 64+: 5 days (capped)

Fixed senior days

For a simple “5 extra days for everyone 60+” policy:

Add the Age-Based Accrual plugin
Set Days per year formula to 5
Set From age to 60
Leave To age at 0 (no upper limit)
Set Accrual method to Yearly at start of year

Tiered age brackets

For different entitlements at different ages, create multiple plugins:

Plugin 1: Ages 55-59

Formula: 2
From age: 55
To age: 59

Plugin 2: Ages 60-64

Formula: 4
From age: 60
To age: 64

Plugin 3: Ages 65+

Formula: 6
From age: 65
To age: 0 (no upper limit)

Birthday-triggered benefit

For benefits that start on the employee’s actual birthday:

Set Accrual method to Yearly on birthday
Configure other parameters as needed

The accrual appears on the employee’s birthday each year.

Monthly senior accrual

For gradual monthly accrual of senior days:

Set Accrual method to Monthly
Set Days per year formula to 5
Configure age parameters

The 5 days are distributed as ~0.42 days per month.

Quarterly senior accrual

For quarterly accrual of senior days:

Set Accrual method to Every 3 Months (Quarterly)
Set Days per year formula to 4
Configure age parameters

The 4 days are distributed as 1 day per quarter.

Troubleshooting

Issue	Solution
Employee didn’t receive senior days	Verify their birth date and check if they meet the “From age” requirement during the accrual year
Formula error	Check formula syntax. Use only `age`, numbers, and basic math operators (+, -, *, /)
Wrong amount calculated	Verify the formula and check “Max days” cap
Need different amounts per age bracket	Create multiple plugins with different “From age” and “To age” ranges
Accrual on wrong date	Check “Accrual method” and “Year start month” settings
