Calculate your vacation accrual rate per pay period with tenure-based tiers. See how years of service increase your annual vacation allotment and per-period earn rate.
Many employers increase vacation allotments based on years of service — a practice known as tiered or tenure-based accrual. A new hire might earn 10 days per year while a 10-year veteran earns 20 days. This calculator shows your per-period accrual rate based on your tenure tier and pay frequency.
Enter your annual vacation hours for your current tenure level and select how often you're paid. The tool divides your annual allotment by the number of pay periods to give you the exact hours you earn each paycheck. It also shows how many accrual periods remain and your projected year-end total.
Understanding tiered accrual is especially important when you're approaching a tenure milestone — you may be about to unlock a significantly higher vacation rate. Whether you are a beginner or experienced professional, this free online tool provides instant, reliable results without manual computation. By automating the calculation, you save time and reduce the risk of costly errors in your planning and decision-making process.
Tenure-based accrual means your rate changes over time. Without recalculating after each milestone, you might undercount your available days. This calculator keeps you current on exactly how many hours you earn per period at your current and next tier. Having a precise figure at your fingertips empowers better planning and more confident decisions.
Accrual Rate = Annual Vacation Hours ÷ Pay Periods Per Year Year-End Projected = Rate × Total Pay Periods Tier Increase = Next Tier Rate − Current Tier Rate
Result: 4.62 hrs/period current — 6.15 hrs/period at next tier
At 120 annual hours on biweekly pay (26 periods), you accrue 120 ÷ 26 = 4.615 hrs/period. After 14 periods you've earned 64.62 hrs. Moving to 160 annual hours would increase your rate to 160 ÷ 26 = 6.154 hrs/period — a 33% increase.
Employers use tiered vacation schedules to reward loyalty and reduce turnover. The most common structure starts employees at 10 days per year and increases by 5 days at each major tenure milestone (typically 3, 5, and 10 years). Executive-level employees may negotiate higher starting tiers.
To see your daily accrual rate, divide your per-period rate by the number of work days in each period. For biweekly pay, that's about 10 work days. This daily rate is useful for prorating vacation when you change tiers mid-period.
If your tenure milestone falls mid-year, you'll accrue at the old rate for part of the year and the new rate for the rest. Your total year-end vacation will be a blended amount. Plan any large vacations for after the bump to take advantage of the higher rate.
Common tiers include: 0–2 years = 10 days, 3–5 years = 15 days, 6–10 years = 20 days, 10+ years = 25 days. Each employer defines its own milestones and corresponding vacation allotments.
Most employers adjust your accrual rate starting the pay period that includes your tenure milestone date. Some wait until the next calendar or anniversary year. Check your HR policy for specifics.
Vacation accrual applies specifically to vacation days only. PTO accrual is broader — it may combine vacation, sick, and personal days into a single bank. The math is the same; the category of time off differs.
Yes, experienced hires often negotiate vacation matching their previous employer's level. This is typically documented in your offer letter as a "years of service credit" for vacation purposes.
Policies vary. Some employers have a rehire recognition policy that restores partial or full tenure credit. Others start you at zero. Government and union jobs often have specific rehire tenure rules.
Many employers offer prorated vacation tiers to part-time staff. For example, a half-time employee at the 15-day tier would receive 7.5 days. Some employers exclude part-timers from vacation benefits entirely.
