Leave accrual explained: monthly, yearly or per pay cycle
Three ways leave can build up, what each one means for new starters and leavers, and how to pick the one that fits your business.
6 min readFor owners and payroll
In short
- Accrual is only the timing of leave: the yearly allowance is the same, but when it becomes available differs.
- Yearly (up front) is simplest for staff; monthly and per-cycle keep balances close to what has been earned.
- The method matters most when someone joins or leaves part way through the year.
- Decide what happens when someone asks for more leave than they have earned so far, and write it down.

Most leave policies start with one number: so many days a year. The harder question is when those days become available. Does a new starter have the full allowance on day one, or do they earn it bit by bit? That timing is called accrual, and the method you choose changes what people see in their balance every week of the year.
This guide covers the three common methods, shows the same allowance worked through each one, and helps you choose. Leave rules are different in every country and sometimes in every contract, so treat this as a way to think about it and check the rules that apply to you before you settle on a policy.
The three methods in one table
| Method | When leave is added | Best for |
|---|---|---|
| Yearly (up front) | The whole allowance on the first day of the leave year | Stable teams, salaried staff, simple admin |
| Monthly | One twelfth of the allowance each month | Most small businesses; a fair middle ground |
| Per pay cycle | A slice each pay period | Hourly or shift teams paid weekly or every two weeks |

Yearly: everything on day one
With yearly accrual the full allowance appears at the start of the leave year. Staff can plan a long break in the first month if they want to, and nobody has to explain why a balance shows 3.33 days.
The cost of that simplicity is risk when someone leaves. A person can take most of their year's leave by spring and resign in early summer, having used more than they earned for the time they worked. Whether you can recover the difference depends on your contracts and local rules, so it is worth knowing the answer before it happens.
New starters need a rule too. Someone who joins half way through the leave year would normally get a share of the allowance for the months that are left, not the whole year.
Monthly: one twelfth at a time
With monthly accrual each person earns one twelfth of the yearly allowance every month. Balances grow steadily, and at any point the balance is close to what the person has earned by working.
The trade-off is early in the year. In the first two months nobody has enough leave for a week away, even though they will by the time summer arrives. Many businesses solve this by letting people borrow against leave they have not yet earned, up to a limit. If you allow that, say how far a balance can go below zero.
Per pay cycle: a slice every payday
Per-cycle accrual adds leave each pay period: weekly, every two weeks, every four weeks or twice a month. It suits teams where pay and hours already run on that rhythm, because the leave added lines up with the pay period it was earned in.
The slices are small, so balances show more decimal places. That is normal. Agree a rounding rule once (for example, show two decimal places and round requests to half days) and use it for everyone.
The same allowance, three ways
- Yearly: 20 days are available on 1 January.
- Monthly: 20 ÷ 12 = 1.67 days a month. By the end of May: 5 × 1.67 = 8.33 days.
- Per cycle, paid every two weeks (26 pay periods): 20 ÷ 26 = 0.77 days a period. After 10 periods: 7.69 days.
- By 31 December all three methods have added the same 20 days.
Now look at what the method does when someone joins or leaves part way through the year.
- Emma Wilson joins on 1 April. Nine months of the leave year remain, so her share is 20 × 9 ÷ 12 = 15 days.
- On yearly accrual she has all 15 days from her first day. On monthly accrual she earns 1.67 days a month and reaches 15 by December.
- Ben Carter is on yearly accrual. He takes 15 days by June and leaves on 30 June.
- For six months worked he earned 20 × 6 ÷ 12 = 10 days, so he has taken 5 days more than he earned.
- On monthly accrual with no borrowing, Ben could not have taken more than 10 days by that date.
How to choose
- Look at how often people leave. If staff turnover is high or work is seasonal, monthly or per-cycle accrual keeps balances in step with time worked.
- Look at how you pay. If people are paid weekly or every two weeks by the hour, per-cycle accrual matches what they already see on payday.
- Think about how staff plan. If your team books long trips early in the year, yearly accrual or monthly accrual with borrowing avoids a lot of awkward conversations.
- Decide the borrowing rule. Either balances cannot go below zero, or they can down to a set number of days.
- Check the rules that apply to you. Some places and contracts say how and when leave must be given.
- Write the choice into your time off policy in one or two plain sentences, with a short example like the ones above.
Mistakes to avoid
- Changing method half way through a leave year without working out each person's balance on the day of the change.
- Forgetting part-time staff. Their allowance is usually a share of the full-time figure, and the accrual slice shrinks with it.
- Using a different leave year for different people without meaning to, for example some on the calendar year and some on their start date.
- Rounding differently each time. Small differences turn into arguments at year end.
- Leaving the leaver rule unwritten. Decide in advance how unused or over-used leave is settled, within the rules that apply to you.
How ClockinBee handles accrual
In ClockinBee each time off type has one or more policies. A policy sets the allowance and whether it is added monthly, yearly or each pay cycle, along with carry-over limits and when carried-over days expire. You can make a policy the company default. A policy can also give more days after a number of years of service, counted from each person's hire date, and you can give a different policy to individual people for a part-time contract or an agreed exception.
When someone requests time off, a preview shows how many days the request uses and the balance that would be left before they send it. Each person has their own working-day pattern and public holiday calendar, so days they do not work are not counted. Managers see balances and a who's-off calendar in one place.
ClockinBee does not know the law where you employ people, and it does not decide your allowance for you. You choose the numbers; it keeps the arithmetic consistent for everyone.
Questions people ask
Does the accrual method change how much leave people get?
No. Over a full leave year each method adds the same allowance. It only changes when the days become available, which matters most for starters, leavers and early-year bookings.
Can someone take leave they have not earned yet?
That is your decision, within the rules that apply to you. Many businesses allow a small negative balance so people can book a holiday early in the year. Set a limit and say what happens if the person leaves while the balance is below zero.
What about a pay period that crosses the end of the leave year?
With per-cycle accrual, pick one rule and keep it: for example, leave is added on the last day of each pay period and counts in the leave year that day falls in.
Should we switch methods?
Only if the current one causes real problems, such as balances that staff cannot follow or regular over-taking by leavers. If you do switch, do it at the start of a leave year and tell everyone their opening balance.
