Understanding the Basics: Plan Year vs. Calendar Year

When navigating the world of business and insurance, two commonly used terms are "plan year" and "calendar year." Essentially, a plan year revolves around the start and end dates that an employer designates for their insurance and benefit plans, which might not necessarily align with a calendar year. In contrast, a calendar year consistently refers to January 1st to December 31st, totaling 365 days in a year.

In a business context, the plan year often defines the duration for which an employer's health plan or FSA (flexible spending account) is effective. The ERISA (Employee Retirement Income Security Act) mandates employers to specify a plan year for their health care and benefit packages. Consequently, the question arises: What is the ERISA plan year? It's the 12-month period selected by the employer for the administration of the employee benefits.

On the other hand, when individuals ponder over questions like Does a calendar year mean 365 days? or What does per calendar year mean?, they are typically referring to a straightforward annual period. This simplicity makes calendar year an appealing choice for many insurance companies when setting the terms of their health plans.

Probing Deeper: What does "Per Calendar Year" Mean?

"Per calendar year" implies any given activity, transaction, or calculation occurring within the confines of a single calendar year. Within the insurance sphere, many policies often have clauses that stipulate limits or benefits that apply "per calendar year."

For instance, an insurance policy may cover two preventive checkups per calendar year, emphasizing the fact that after the two checkups, any further checkups within that year will be an out-of-pocket expense for the insured. This distinction becomes pivotal when understanding insurance resets. Many aspects of an insurance plan, such as deductibles and copays, often reset at the start of a new calendar year.

Unveiling the Calendar Year Deductible

Deductibles play a pivotal role in how insurance policies work. In the realm of health insurance, a calendar year deductible is the amount an insured individual must pay for medical care out of pocket before the insurance company starts to contribute.

For example, if a person's health care plan has a $1,000 calendar year deductible, they must pay the first $1,000 of their medical expenses before the insurance kicks in. This raises another pertinent question: How do you meet your deductible? This can be achieved through medical visits, prescription costs, and other qualified medical expenses.

There are evident advantages to a calendar year deductible system. Firstly, it's straightforward — everyone knows when it resets. Yet, there's also a downside. If an insured person incurs significant medical expenses late in the calendar year, they might have to meet their deductible in full, only for it to reset again shortly thereafter.

Grasping the Concept: Per Calendar Year Vs. Per Plan Year

The terminology "per calendar year" often gets juxtaposed with "per plan year," particularly in insurance contexts. While "per calendar year" adheres to the regular calendar, "per plan year" aligns with the specific timeframe determined by an employer for a health plan or benefit.

For instance, if an employer's health plan begins in July, any mention of "per plan year" benefits or limits would apply from July of one year to June of the next. When choosing between the two for insurance benefits, the consistency and predictability of "per calendar year" might be appealing to some, while others may appreciate the flexibility that a plan year provides, especially if it aligns with fiscal years or other business-specific timelines.


Understanding the nuances between plan year and calendar year is critical for both employers and employees. These terms dictate the operation and benefits of insurance policies. The implications of "per calendar year" and "per plan year" can significantly impact how policyholders use and benefit from their insurance.

The "calendar year deductible" is a frequently used insurance term which resets annually, guiding the insured on the upfront medical costs they must bear. Whether one opts for "per calendar year" or "per plan year" systems, understanding these terminologies ensures they can make informed decisions about their health care, maximizing benefits and minimizing out-of-pocket costs.

Lastly, while navigating these complexities, always remember that while insurance provides a safety net, it's the comprehension of these nuances that turns it into a trampoline, propelling you towards sound financial and medical decisions.

Addressing Top Questions on Plan Year and Calendar Year

  1. What is the ERISA plan year?
    The ERISA (Employee Retirement Income Security Act) plan year is a specified 12-month period designated by an employer for the administration and management of employee benefits. It serves as the fiscal year for benefit plans and can be any 12-month period chosen by the employer. This year often defines the period during which certain benefits can be used and when they might reset.
  2. What is a plan year?
    A plan year refers to a consecutive 12-month period during which an employee benefits plan is operational. It can be aligned with the calendar year or any other 12-month span chosen by the employer, such as a fiscal year or an anniversary year based on the company’s incorporation date.
  3. Does a calendar year mean 365 days?
    Yes, a calendar year refers to a period starting from January 1st and ending on December 31st, making it 365 days long, except in leap years when it is 366 days.
  4. What does per calendar year mean?
    "Per calendar year" implies any given activity, transaction, or calculation occurring within the bounds of a single calendar year. In insurance, it often denotes the limits or benefits that apply within the January to December timeframe, irrespective of when the policy was initiated.
  5. Does insurance reset every calendar year?
    Most insurance plans, particularly health insurance, have aspects like deductibles, out-of-pocket maximums, and certain benefits that reset at the start of each calendar year. However, specifics can vary based on the policy terms.
  6. What is the difference between calendar year and policy year?
    While a calendar year consistently spans from January 1st to December 31st, a policy year is the 12-month duration starting from the effective date of the insurance policy. For instance, if a policy is initiated on July 15th, the policy year would run until July 14th of the following year.
  7. What does calendar year mean for insurance?
    In insurance, a calendar year dictates the period during which certain financial thresholds like deductibles or out-of-pocket maximums must be met. It also can dictate the timeframe for certain benefits, such as the number of covered checkups. All these reset with the onset of a new calendar year.
  8. How do you meet your deductible?
    Meeting a deductible means paying out-of-pocket for medical services until you reach the deductible amount set in your health plan. It can be achieved through various medical expenses, like doctor's visits, hospital stays, or prescription medications. After this amount is met, the insurance typically starts covering a more significant portion or all of the expenses, depending on the plan terms.
  9. Can a plan year be longer than 12 months?
    Typically, a plan year is a consecutive 12-month period. However, in some rare circumstances, a short plan year may be designated, usually for administrative reasons or due to changes in the plan structure. This short plan year would be less than 12 months, but it is unusual for a plan year to exceed 12 months.
  10. What is the difference between out-of-pocket maximum and calendar year deductible?
    A calendar year deductible is the amount an insured individual must pay out-of-pocket before the insurance company starts covering a portion of the costs. The out-of-pocket maximum, on the other hand, is the maximum amount an insured individual would have to pay for covered health care services in a single calendar year. After reaching this maximum, the insurer would pay 100% of the covered expenses. The out-of-pocket maximum includes deductibles, coinsurance, and copayments, but not premiums.
