Vacation Balance Calculator
It is easy to lose track of paid time off. You earn a little every pay period, take a few days here and there, and the pay stub figure never quite matches your own count. This vacation balance calculator settles it with four numbers: your starting balance, any carryover from last year, what you earned, and what you took. It works in days or hours and shows the full breakdown behind the result.
The unit toggle only relabels the figures: the math is identical in days and hours, and the tool does not convert between them. Enter every figure in one unit. Negative entries are accepted, so a negative balance is shown as entered rather than blocked.
Quick Answer
Start with 12 days, add 3 days carried over from last year and 5 days earned, then subtract 6 days taken, and the vacation balance is 14.00 days. The formula is Balance = (Starting + Carryover) + Earned − Taken, and it works the same in hours: the same run in hours would be entered entirely in hours. Those figures are pre-filled above, so one click on Calculate reproduces the answer.
Key takeaways
- Your balance is a ledger, not a guess: everything that added time goes in, everything you used comes out.
- Carryover is a separate field here. Enter only the days that actually rolled over, after any cap in your policy.
- The days and hours toggle only changes the label. Pick one unit and enter every figure in it.
- A negative result is possible and meaningful: either you borrowed against future accrual, or one of the entries has the wrong sign.

How to use the vacation balance calculator
Enter four figures from the same period and in the same unit, then read the balance and its breakdown. The result stays hidden until you calculate.
- Pick Days or Hours. Match the unit your pay stub or HR portal uses. Switching the toggle hides any old result, because a figure entered in days is not converted to hours for you.
- Enter your starting balance: what you had at the start of the period. This field is required.
- Add carryover if you have it: unused time that rolled in from last year, after any cap. Leave it at 0 if nothing rolled over. It is the only optional field.
- Enter earned and taken: the time accrued during the period and the time you actually used during that same period. Both are required; enter 0 if either is none.
- Click Calculate. The balance appears to two decimals with a five-line breakdown, so you can check each piece against your own records before you trust it.
Three of the four fields are validated: leave the starting balance, earned, or taken blank and you get a specific message under that field ("Enter your starting balance.", "Enter earned time (0 if none).", "Enter taken time (0 if none).") and no result. Negative numbers are not blocked. Taken time larger than your balance, or a negative entry, produces a negative balance, which is the honest answer for anyone whose employer lets them borrow time.
The vacation balance formula
Vacation balance = (Starting balance + Carryover) + Earned − Taken. That is the whole formula, and it is deliberately simple: a leave balance is a running ledger, so addition and subtraction are all it needs.
The starting balance is what you had when the period began. Carryover is last year's unused time that your policy allowed to roll forward. Earned is what accrued during the period, and taken is what you used. Because nothing is multiplied or converted, days and hours behave identically, which is why one toggle covers both. The one way to get a wrong answer is mixing units: a starting balance in days, earnings in hours. Keep everything in one unit, or convert first by dividing hours by your standard workday length, usually 8.
If your unknown is the earned figure rather than the balance, work out your per-period earnings with an accrual rate calculator first, then bring the total earned back here.
Worked example: 12 days in, 14 days out
You started the quarter with 12 days, carried 3 unused days over from last year, earned 5 more days, and took 6 days off. Those are the pre-filled figures in the calculator, and it returns 14.00 days.
The same ledger, drawn as shares of the 20 days that were available at the peak, looks like this:
Four more runs of the same tool, including the two edge cases people actually hit, are below. Type any row in and you will get the same figure back.
| Starting | Carryover | Earned | Taken | Balance |
|---|---|---|---|---|
| 12 days | 3 days | 5 days | 6 days | 14.00 days |
| 80 hours | 0 hours | 16 hours | 40 hours | 56.00 hours |
| 10 days | 0 days | 2.5 days | 12.5 days | 0.00 days |
| 5 days | 0 days | 1 day | 8 days | −2.00 days |
| 0 days | 0 days | 0 days | 0 days | 0.00 days |
How vacation time accrues, and what a typical balance looks like
Most employers do not hand you a year of vacation on January 1. You earn it gradually, a slice per pay period or per hour worked, and the rate usually grows with tenure.
The slice is simple arithmetic: annual allowance ÷ pay periods per year. A 20-day allowance over 24 semi-monthly periods is about 0.83 days per period; an hourly system granting 160 hours over a 2,080-hour work year is about 0.077 hours of leave per hour worked. Add the slices since your starting-balance date and you have the earned figure this calculator wants.
For scale, the Bureau of Labor Statistics reports that private industry workers with paid vacation average 11 days after 1 year of service, 16 after 5 years, 18 after 10 years, and 20 after 20 years (Employee Benefits survey, March 2026). If your balance is far below those lines for your tenure, the gap is worth a question to HR, starting with whether your accrual rate in the system matches your offer letter.
| Years of service | Average paid vacation days, private industry |
|---|---|
| After 1 year | 11 days |
| After 5 years | 16 days |
| After 10 years | 18 days |
| After 20 years | 20 days |
One federal point worth knowing before you argue about any of this: no federal law requires an employer to offer paid vacation at all. The Fair Labor Standards Act does not mandate vacation pay, according to the U.S. Department of Labor's vacation leave guidance, so your balance lives and dies by your employer's written policy and your state's rules, not by a national entitlement.
Carryover, caps, and use-it-or-lose-it rules
Carryover is where balances go wrong. Whether last year's unused days still exist on January 1 depends on your policy and your state, and the calculator only counts what you tell it survived.
Three policy shapes cover most workplaces. Some employers let unused time roll forward with a cap, so only part of a large leftover balance survives. Some run use-it-or-lose-it, where unspent days expire at year end, in states that allow it. And a few states treat accrued vacation as wages already earned: California's labor agency states that vacation cannot be forfeited once earned, so it carries until used or paid out. Before you trust a January balance, check two things in your own policy: the carryover cap, and whether an accrual cap stopped you earning mid-year once your balance hit a ceiling.
Enter only the days that actually rolled over in the carryover field. If 9 days were left but the cap is 5, the honest input is 5, and the other 4 are gone, not pending. When employment ends, the leftover balance turns into a money question: several states require it to be paid out, and a selling leave calculator estimates what an unused balance is worth in pay.
Part-time schedules, mid-year starts, and prorating
Part-time balances follow the same formula after one extra step: prorate the allowance to your schedule first. The usual method is your hours ÷ full-time hours × the standard allowance.
A 30-hour week against a 40-hour standard is 0.75, so a 20-day full-time allowance becomes 15 days. Mid-year starters get the same treatment for their first partial year. If your schedule is irregular or changed mid-year, a prorated PTO calculator works out the earned figure period by period, and a prorated days off calculator covers the partial-year case; bring the resulting earned total back here and track the balance with it. Keep the units consistent when you do: prorated results usually come out in days, so run this calculator in Days mode to match.
Vacation and public holidays are separate buckets at most employers. If your question is what a worked holiday pays rather than what your balance holds, a holiday pay rate calculator is the right tool for that one.
What most competing tools miss
The tools ranking for this search mostly answer a different question, or stop one field short:
- Accrual-first calculators (Rize, PTOCalculator-style tools): strong on projecting a future balance from a hire date and an accrual schedule. The gap is the present-tense check: if you already know your four ledger figures, a projection model makes you reconstruct them from a start date instead of just entering them.
- Spreadsheet templates and tracker apps: good for a year of entries, but they are paid downloads, app installs, or accounts. A one-off balance check should not need any of that.
- Vacation pay estimators: several top results estimate the wages you will receive while on vacation. Useful, but a pay projection does not tell you how many days you have left, which is the question this page answers.
- Balance tools with no carryover field: rolled-over days are part of most real balances, yet many simple tools omit the field and push the addition onto you. Here carryover is explicit, capped value and all.
- Hours-only tools: payroll thinks in hours; people plan trips in days. The toggle here lets you work in whichever unit your records use, with the limit stated plainly: it relabels, it does not convert.
Frequently asked questions
Add your starting balance and any carryover, add the time you earned, and subtract the time you took: Balance = (Starting + Carryover) + Earned − Taken. With 12 days starting, 3 carried over, 5 earned and 6 taken, the balance is 14.00 days.
Vacation days are time off for rest and travel. PTO, or paid time off, is often a single bank that also covers sick days and personal days. The balance math is identical either way; only the label and what draws from the bank change.
You earn a small amount of leave each pay period or hour worked: accrual rate × time worked = time earned. A 20-day annual allowance spread over 24 semi-monthly periods is about 0.83 days per period, and many employers raise the rate with years of service.
It depends on your employer policy and your state. Some employers let days carry over, often with a cap; some run use-it-or-lose-it policies where state law allows them; and a few states, California being the best known, treat accrued vacation as earned wages that cannot be taken away once earned.
Yes, in two ways. Some employers let you borrow against future accrual, which shows as a negative balance you earn back over time. This calculator also accepts negative entries and taken time larger than your balance, so it will show a negative result rather than blocking you: check your signs if the number surprises you.
It depends on your state and your employer policy. Several US states require payout of accrued, unused vacation at separation, while others leave it to the written policy. Check your state labor department rules and your handbook before your last day, not after.
Divide hours by the length of your standard workday, usually 8. So 112 hours is 14 days. This calculator does not convert for you: pick Days or Hours at the top and enter every figure in that one unit.
Prorate the allowance first: your weekly hours ÷ full-time weekly hours × the standard allowance. A 30-hour week against a 40-hour standard earns 75 percent of the full-time amount. Then track the prorated figures with the same balance formula.
