Leave accrued for part of a year calculator
Type the annual days from the handbook and how many months have already passed. 15 days and 6 months round to 8 days. The United States sets no federal minimum for paid vacation.

How it works
Allowance15
Months6
Accrued8
15 handbook days across the year
Month 1 is 1 day. Month 6 is 8 days, because 7.5 rounds to 8. Month 12 is the full 15 days. The United States sets no federal minimum for paid vacation.
This calculator splits the annual allowance across the months that have already passed. It multiplies the allowance by the months, divides by 12, and rounds to the nearest whole number. 15 days over 6 months comes to 7.5, so the result is 8 days. One month of 15 days is about 1.25, so the result is 1 day. A full year of a 15-day allowance is 15 days.
The United States sets no federal minimum for paid vacation, so the days come from the handbook. A 10-day allowance and 6 months give 5 days. Two months of a 15-day allowance are 2.5, which rounds to 3.
Entitlement must be at least 1 day. An allowance of half a day will not produce any leave, even after 12 months. Months may be zero: 20 days and 0 months give 0 days. The calculator will not accept a negative number of months. The formula does not cap entitlement at 26 days. If you type 30 days and 12 months, the result is 30 days.
Carryover and days already used are optional. Empty fields count as zero. When either is greater than zero, the calculator shows what is left: accrued days plus carryover minus days already used. That number cannot go below zero. 26 days, 6 months, 4 days from last year, and 5 already taken give 13 accrued days and 12 remaining. If the days already used are greater than accrued days plus carryover, remaining is 0, not a negative number.
The days come from the entitlement and the months you type. Use the number from the handbook, such as 10, 15, or 20. The calculator does not check how long you have worked. Last year's days go in the carryover field, and days already taken go in their own field. It does not turn unused days into pay.
The employment-fraction calculator counts monthly hours from a fraction, not leave days. Pay at a fraction multiplies the salary. On this page the result stays in days. 6.5 months at an entitlement of 26 days is about 14.08, so rounding gives 14 days. You can type a comma or a period for the decimal.
The result is in days, not in money. The currency symbol in the header does not turn 13 into another number. An example button fills in the entitlement and the months together. The entitlement alone, or the months alone, is not enough for a result.
How to use
- In the allowance field, type the annual days from the handbook, or choose 10, 15, or 20. 15 days and 6 months round to 8 days.
- In months, type how many months of the year have already passed. Six months at an entitlement of 26 days gives 13 days. One month at 26 days gives 2 days, because 2.17 rounds to 2.
- Click Calculate and read accrued days. Zero months at an entitlement of 20 days gives zero days. An entitlement below 1 day will not produce a result.
- Leave the carryover field and the days already used field empty if you only want the days earned this year. With 13 accrued days, 4 days from last year, and 5 already taken, 12 days are left.
- The remaining row appears when carryover or the days already used are greater than zero. The remaining days will not go below zero, even when the days already used are greater than the days you have.
Formula
accrued = round(entitlement × months / 12)
remaining = max(0, accrued + carryover − used)
Entitlement is at least 1 day. Months can be zero. Empty carryover and empty days already used count as zero.
Entitlement, months, and leave days
Accrued days are the entitlement multiplied by the months and divided by 12, rounded to a whole day. 26 days and 6 months give 13 days. 20 days and 3 months give 5 days.
- entitlement
- Annual leave in days. 26 days at 6 months give 13 days. 30 days and 12 months give 30 days. The minimum is 1 day.
- months
- Months worked in the year. Six months at an entitlement of 26 days give 13 days. 6.5 months is about 14.08, which rounds to 14 days.
- days
- The result in days, not money. 13 days plus 4 carried over minus 5 already used leaves 12 days.
Real-life examples
Example 2
20 days and 12 months give 20 days, the full entitlement.
Example 3
20 days and 3 months give 5 days after rounding.
Example 4
26 days and 1 month give 2 days, because 2.17 rounds down to 2.
Example 5
26 days and 12 months give 26 days, a full year.
Example 6
24 days and 6 months give 12 accrued days.
Example 7
26 days, 6 months, 4 carried over, and 5 already used give 13 accrued days and 12 left to use.
Example 8
20 days and 9 months give 15 days after rounding.
When this helps
- You check how many of 26 days you have after six months before you plan a longer trip.
- You enter 4 days from last year and 5 already taken, to see the 12 days that are still left.
Frequently asked questions
How many days do 15 days and 6 months give?
8 days. 15 times 6 divided by 12 is 7.5, and 7.5 rounds to 8. One month of 15 days rounds to 1 day. Two months of those 15 days round to 3 days, because 2.5 rounds to 3.
Does the United States require paid vacation?
No. There is no federal minimum for paid vacation. Type the number of days from the handbook. A 10-day allowance and 6 months give 5 days.
How many days do I get from 26 and 6 months?
13 accrued days. 20 days and 3 months give 5 days. 24 days and 6 months give 12 days.
Why do 26 days and 1 month give 2, not 2.17?
The calculator rounds to the nearest whole number. 26 divided by 12 is about 2.17, so the result is 2 days. There is no separate rule that always rounds the fraction down.
Is 26 days a statutory ceiling?
No. The formula does not cap entitlement at 26. 30 days and 12 months give 30 days. You type the handbook number yourself.
What if entitlement is 0.5 days?
The calculator will not produce a result. Type at least 1 day. An allowance of half a day will not produce any leave, even after 12 months.
When does the remaining row appear?
When carryover or the days already used are greater than zero. 13 days plus 4 carried over minus 5 already used leaves 12 days. Without those fields, you see only the accrued days.
What if the days already used are greater than the balance?
Remaining is 0. The calculator does not show negative leave. The accrued days still stay in the first line of the result.
How is 6.5 months calculated at an entitlement of 26 days?
26 days times 6.5 months, divided by 12, is about 14.08. Rounding gives 14 days. A comma and a period both work as the decimal mark.
How is this different from employment-fraction hours?
This calculator splits leave days across the year. The hours calculator multiplies full-time hours by a fraction. The results are not the same.
Does this calculator turn unused leave into pay?
No. The result stays in days. There is no pay for unused days on this page. The part-time pay calculator and the hourly-rate calculator work out pay, not this leave balance.
Is the result in money?
No. Leave is in days. The currency symbol in the header does not turn 13 into another number. Pay is calculated on the salary pages.
Knowledge sources
Leave is the allowance times the months, divided by 12, plus carryover, minus the days already used. This is not a statement of labor law.
