Biweekly accrual with cap
- Accrual per period: 4 hours; 26 periods → 104 hours accrued
- Starting 40 + 104 − 80 used = 64 hours before cap
- Cap 120 → Ending balance 64; Lost to cap = 0

Overview
Paid time off feels simple—hours go in, hours come out—but the details of accrual, usage, and carryover caps can make it surprisingly hard to know where you’ll stand by year-end. This PTO accrual calculator takes your current balance, the rate you earn hours each pay period, and your planned time off and turns them into a clear projection of total hours earned, hours used, and how many hours you’re on track to carry forward.
How to use this calculator
- Enter your starting PTO balance in hours, based on your latest pay stub or HR portal.
- Enter your accrual per pay period and the number of pay periods per year (for example, 26 for biweekly, 24 for semi-monthly, 12 for monthly, or 52 for weekly payroll).
- Add the number of PTO hours you expect to use this year and your employer’s carryover cap, then review your projected ending balance and any hours that would be forfeited. Adjust your planned usage or assumptions to hit the balance you want at year-end.
Inputs explained
- Accrual per pay period
- Hours of PTO earned each paycheck (or per accrual cycle).
- Pay periods per year
- Typical values: 12 monthly, 24 semi-monthly, 26 biweekly, 52 weekly.
- Planned PTO used
- Hours you expect to take off this year.
- Carryover cap
- Maximum PTO hours allowed to carry; extra hours above this are forfeited.
How it works
The calculator starts by estimating how many hours you will earn over the year: Total accrual = Accrual per pay period × Pay periods per year. This mirrors how most PTO systems credit hours each payroll cycle.
Next it projects your year-end balance before any caps by combining your starting balance, total accrual, and planned usage: Ending balance before cap = Starting balance + Total accrual − Planned PTO used. This gives a simple view of whether you’re building or drawing down your PTO bank.
If your employer enforces a carryover cap, the calculator then applies that limit at year-end: Ending balance after cap = Min(Ending balance before cap, Carryover cap). Any hours above the cap are treated as forfeited or “use-it-or-lose-it” time.
Finally, it computes Hours lost to cap = Max(0, Ending balance before cap − Carryover cap) so you can see exactly how many hours you risk leaving on the table if you do not adjust your vacation plans.
Formula
Total accrual = Accrual per period × Pay periods Ending balance = Starting + Total accrual − Used (capped at carryover limit) Hours lost = Max(0, Ending balance before cap − Cap)
When to use it
- Checking if you’ll hit a use-it-or-lose-it cap.
- Planning vacations while keeping a buffer of PTO.
- Adjusting accrual or carryover assumptions when changing employers or pay schedules.
Tips & cautions
- If your employer has separate vacation, sick, and personal time buckets, run the calculator separately for each bank so you don’t mix rules or caps that apply differently to different types of leave.
- If your accrual increases with tenure or promotion, plan to re-run the calculator when you cross into a new tier. For a rough annual estimate, you can also average your old and new accrual rates for the year.
- Some policies cap accrual each period once you hit the maximum balance rather than only applying a cap at year-end. Ask HR how your employer enforces caps so you can interpret the results correctly.
- Consider modeling both a conservative scenario (taking all of your planned vacations) and a backup scenario (adding extra buffer days for illness or emergencies) to understand a realistic range of ending balances.
- If your company offers PTO cash-outs, sellbacks, or special rules near separation, combine this calculator with your HR documentation to avoid surprises about which hours will be paid out versus forfeited.
- Simplified annual snapshot; does not model month-by-month caps or front-loading policies.
- Assumes a single carryover cap and linear accrual; check your employee handbook for exact rules.
- Does not include cash-out or PTO sellback programs.
Worked examples
High balance hitting cap
- Starting 120, accrual 5 hours × 26 = 130, usage 40
- Balance before cap = 120 + 130 − 40 = 210
- Cap 160 → Ending balance 160; Hours lost = 50
Deep dive
Use this PTO accrual calculator to turn your employer’s time-off policy into a concrete projection of hours earned, hours used, and how many hours you are likely to carry into next year under a given carryover cap.
Enter your starting PTO balance, accrual per pay period, number of pay periods per year, planned time off, and carryover limit to see total accrual, your projected year-end balance, and any hours that would be forfeited under a use-it-or-lose-it policy.
Perfect for employees planning vacations, managers helping teammates schedule time off, or HR teams documenting example scenarios—this tool makes it easy to test different accrual rates, pay schedules, and caps before you make commitments on your calendar.
FAQs
- Does this handle monthly or weekly payroll?
- Yes. Set pay periods per year to match your payroll cycle—for example, 12 for monthly, 24 for semi-monthly, 26 for biweekly, or 52 for weekly. As long as your accrual rate is expressed per pay period, the math will line up with how your PTO is credited.
- What if my accrual rate steps up with tenure?
- You can either re-run the calculator when your accrual rate changes or approximate the year by averaging your hours per period across the old and new rates. For major changes, it’s often clearer to break the year into two parts and calculate each segment separately.
- Do caps apply per period or only at year-end?
- This model applies a single carryover cap at year-end. Some employers instead stop accruing new hours once you hit a maximum balance during the year. In that case, this calculator will slightly overstate how many hours you might end with—check your policy or talk with HR about how and when caps are enforced.
- Can I include separate sick and vacation banks?
- Yes, but you should model each bank separately unless your employer explicitly combines them into a single PTO bucket with the same accrual rate and cap. Different banks often have different rules for carryover, usage, and payout at termination.
- What if there is no cap?
- If your policy has no practical carryover limit, you can either set the carryover cap to 0 (to effectively ignore it) or to a very high number that you are unlikely to reach. In both cases, the hours lost to cap will show as zero.
- Can I use this with an “unlimited PTO” policy?
- Not directly. Unlimited PTO policies typically do not bank hours or track balances the same way traditional accrual systems do, so there is no official carryover cap or forfeiture. You can still use the calculator as a personal planning tool by pretending you have a notional target number of days, but your manager’s expectations and approval practices matter more than the math.
- Does this account for local labor laws or payout rules?
- No. PTO, vacation, and paid leave laws vary by country, state, and city, and some employers are required to pay out unused balances while others are not. This calculator focuses solely on hours earned, used, and forfeited under a simple accrual and cap model. Always review your employee handbook and local regulations or talk with HR for authoritative guidance.

This PTO accrual calculator is for personal planning only. It assumes a simple linear accrual rate, a single year-end carryover cap, and no mid-year policy changes. Real-world policies may accrue based on hours worked, cap balances during the year, treat different leave buckets separately, or be constrained by local labor laws. Always rely on your official HR documentation, pay stubs, and conversations with HR or your manager for exact balances and rules, and do not make employment or leave decisions based solely on these estimates.
