Companies award time off in hours or days. Select the unit of time your company uses for your specific time off policy. You can typically find this in your employee handbook and/or vacation policy documents.

How much you can carry over yearly?
Depending on your company’s time off policy, you may be allowed to “carry over” or “rollover” some unused time off at the end of the year. If your company does not allow you to carry over any time off (usually called “Use-it-or-loose-it”), add “0” in the calculator above.

Start date of accruals
Most companies in the United States require employees to “accrue” or earn their time off throughout the year as they work. Usually, most companies start accruals on either January 1st or a specific date, like your hire date.

How much you accrue
The amount of units (hours or days) you earn every accrual accrual period. You can find this information in your employee handbook and/or vacation policy documents.

What are PTO Accruals?

As an employee works, they earn or are awarded paid time off (PTO) based on the hours they work in a given period of time. This process of earning time off is referred to as “accruing” time off or accrual-based time off policies. When the time off being accrued is classified as “paid”, then it’s referred to as accrual-based paid time off or accrual-based PTO. Very subtle but important naming distinctions, as any time off classified as paid, has to be accounted for as a liability to the organization.

Most companies that use accrual-based PTO use hourly PTO accrual for hourly employees and bi-weekly or semimonthly accrual for salaried employees (aligning with their payroll schedule). Factors that impact PTO accrual include state laws, company policies, and union contracts.

PTO accrual is based on rate, period, and hours worked.

What Happens to Unused Accrued PTO

This depends on your state’s laws and your company’s PTO policies.

In some PTO policies, employees forfeit any PTO they haven’t used by the end of the year (or the end of the accrual cycle). However, three U.S. states prohibit “use-it-or-lose-it” policies.

This is why some companies use PTO rollovers with expiration. For example, unused vacation might carry over from one year to the next but then expire at the end of February. This gives employees a chance to make use of their earned PTO but limits the financial liability that the company carries. However, rollovers with expiration can still create resentment amongst employees who feel like they're being cheated out of something they've earned.

A more popular and flexible option is PTO conversion. Conversion enables employees to convert their extra vacation into cash, retirement contributions, student loan payments, college savings, and more. PTO conversion is basically an
