TeamPredict HR Calculators

Calculate a week of overtime pay at time and a half under the federal FLSA rule (hours over 40 in the week) or California's rules (daily overtime over 8 hours, double time over 12, the seventh consecutive day, and the weekly 40). Use rule_set federal with total hours worked in the week and any extra pay that counts toward the regular rate, such as a nondiscretionary bonus; use rule_set california with the hours worked on each of the seven days. Returns regular and overtime hours and pay and the week's total, gross before tax. Use us_paycheck_take_home with overtime_hours_per_week for take-home pay including overtime, and hourly_to_salary for converting pay without overtime.

Estimate a severance package: weeks of pay per year of service times years of service times weekly pay, with an optional plan minimum and maximum, plus unused PTO paid out, employer-paid health coverage and other lump sums. Use it for an employer budgeting an exit or an employee checking an offer; every input is the plan's own terms, because US federal law sets no severance formula. Use cost_of_a_bad_hire for the all-in cost of a failed hire instead. Amounts are before tax.

Find the date that is a given number of business days after (or before) a start date, skipping weekends and optionally US federal holidays. Use it to answer 'what is the due date 10 business days from now?', delivery dates, response deadlines and notice periods. Use business_days_between instead to count the working days between two known dates, and add_to_date to move by calendar years, months, weeks or days. The start date itself is not counted; day 1 is the next business day. Holidays are the 11 US federal holidays with observed dates. Valid for years 2000 to 2100.

Move a date and clock time forward or back by days, hours and minutes in a US time zone and get the resulting date and time. Days move the calendar date and keep the clock time (the way a phone calendar does); hours and minutes are counted as they really pass, so a daylight saving change inside the span is handled. Use time_duration_between instead to measure the gap between two known date-times, add_to_date for calendar years, months and weeks, and convert_time_zone to show a moment in other zones.

Add or subtract years, months, weeks and days to or from a calendar date and get the resulting date with its weekday, ISO week and day of the year. Use it for 'what is the date 90 days from today?', contract end dates, probation periods and anniversaries. Years and months move by the calendar first (Jan 31 plus one month is the last day of February), then weeks and days. Use add_business_days to skip weekends and holidays and days_between_dates to measure the gap between two dates. Valid for years 2000 to 2100.

Convert one date and clock time from a source time zone to other time zones, with daylight saving applied for that date, and find the stretch of the day when it is 9 AM to 5 PM in every zone at once. Use it to schedule across offices, pick a meeting time for a distributed team, or answer 'what is 3 PM Eastern in London?'. Supports 24 zones (US zones, UTC and major world zones); the valid zone ids are listed in the schema. Use time_duration_between for the length of time between two moments.

Estimate the total cost of one bad hire: the salary paid for lost productivity plus recruiting, onboarding, manager time, severance and the cost of hiring a replacement. Use it for a single failed hire with a known salary and tenure. Use employee_turnover_cost instead for the company-wide cost of turnover across many employees, and severance_pay for the pay owed to a departing employee. Every cost line is optional and defaults to the TeamPredict calculator's default; set a line to 0 to leave it out.

Calculate the employee retention rate exactly, by separating leavers who were on the payroll at the start of the period from leavers who were hired during it. Use it when you can tell those two groups of leavers apart; it returns the standard retention rate, the new-hire retention rate, the turnover rate and the ending headcount, and shows why retention and turnover do not add up to 100%. Use employee_turnover_rate instead when you only have one total for people who left.

Estimate what employee turnover costs a company per year, and how much cutting turnover would save. Use it when you know headcount, average salary and the annual turnover rate and want the dollar cost of people leaving. Use employee_turnover_rate instead to work out the turnover rate itself from headcounts and leavers, and cost_of_a_bad_hire for the cost of one specific failed hire. Returns departures per year, cost per departure, total annual cost and the yearly saving from a given cut in turnover. Same formula as the TeamPredict turnover cost calculator.

Calculate the employee turnover (attrition) rate for a month, quarter or year from starting headcount, ending headcount and the number of people who left. Use it when you have headcounts and separations and need the rate; it also annualizes a monthly or quarterly rate. Use employee_retention_rate instead when you can split leavers into people who were there at the start and people hired during the period, and employee_turnover_cost to price the turnover in dollars. Returns the turnover rate for the period, the annualized rate, average headcount and a simple retention rate.

Calculate an employee Net Promoter Score (eNPS) from survey response counts: the percentage of promoters minus the percentage of detractors, from -100 to +100. Use it when you have the count of people who answered 9-10 (promoters), 7-8 (passives) and 0-6 (detractors) to the question 'How likely are you to recommend working here?'. Returns the score, both percentages and a rule-of-thumb reading (not a universal benchmark).

Convert pay between hourly, daily, weekly, biweekly, semimonthly, monthly and yearly, in either direction, from one amount. Use it for 'what is $25 an hour per year?' or 'what is $90,000 a year per hour?'. It uses hours per week and paid weeks per year (default 40 hours and 52 weeks), so a 2,080-hour year is the default. Amounts are gross, before tax. Use us_paycheck_take_home for take-home pay after tax and overtime_pay for pay that includes overtime hours.

Convert between military (24-hour) time and standard 12-hour AM/PM time, in either direction. Give military_time (for example 1345, 13:45 or 0800) to get the standard time, or hour_12, minute and period to get the military time. Returns the converted time in every common written form, the plain-English name for special times (midnight, noon) and the hour of the military-time chart it sits in. Use military_shift_hours instead to find how many hours run between two military times.

Work out how paid time off accrues: hours earned per pay period, per month and per hour worked, plus the balance after each pay period, with an optional balance cap and hours already used. Use it to design or explain a PTO policy, or to project an employee's balance by year end. Accrual pauses while the balance sits at the cap and resumes once time is used. Use hourly_to_salary or salary_increase for pay questions, not this tool.

Calculate a pay raise: the new annual and hourly pay, the raise per year, month and biweekly paycheck, the raise as a percentage, and whether it keeps up with inflation. Give either raise_percent (a percentage raise on current pay) or new_pay (the new pay, from which the percentage is worked out), and the pay as per year or per hour. Use hourly_to_salary instead to convert between pay periods without a raise, and us_paycheck_take_home for take-home pay after tax. All amounts are before tax.

Work out how much time passes between a start and an end date and time, in days, hours and minutes, accounting for daylight saving changes in the chosen US time zone. Use it for shift lengths that cross midnight, elapsed time on a ticket, on-call windows and billing time. Use days_between_dates for whole calendar days, add_time_to_datetime to move a date-time forward or back by a known amount, and military_shift_hours for a shift written in 24-hour times only.

Calculate how much tax is withheld from a US bonus in 2026 and what is left: federal income tax (the 22% flat rate or the combined method, 37% above $1 million), Social Security, Medicare, and the state's own bonus withholding rule, for all 50 states and DC. Use it for 'how much of my $X bonus will I keep in <state>?'. Withholding is not the final tax: the bonus is taxed at your normal rate on your return. Use us_paycheck_take_home instead for regular pay, and salary_increase for a raise. When the bonus is paid on its own it also returns the result under the other federal method so the two can be compared.

Calculate US take-home (net) pay from a salary or an hourly wage for 2026, after federal income tax (from the Form W-4), Social Security, Medicare and the state's own income tax and payroll contributions, in any of the 50 states or DC. Use it for 'how much will I take home on $X in <state>?', for comparing states, or to price an offer; it also returns the full-year totals and what the employer pays on top. Use us_bonus_tax instead for tax withheld from a bonus, overtime_pay for the extra pay for overtime hours before tax, and hourly_to_salary for converting pay between hour, week, month and year without tax. Assumes the 2026 federal withholding method and the state's published employer withholding formula, one job, and a W-4 filed in the standard way.

Count the business days (Monday to Friday, optionally skipping US federal holidays) between two dates. Use it for working-day questions such as notice periods, delivery windows, payroll runs and project lead times. Use add_business_days instead to find the date that is N business days from a start date, and days_between_dates for plain calendar days. Holidays are the 11 US federal holidays with their observed dates when one falls on a weekend; company and state holidays are not included. Valid for years 2000 to 2100.

Count the calendar days between two dates and break the gap into weeks, months and years, with the weekdays and weekend days inside it. Use it for 'how many days until X', tenure, age of a record, notice periods in calendar days and countdowns. Use business_days_between instead to leave out weekends and federal holidays, and time_duration_between when clock times matter. Valid for years 2000 to 2100.

Count full-time equivalent employees (FTE) from full-time staff and groups of part-time staff, and run the Affordable Care Act count that decides whether an employer has 50 or more full-time equivalents. Use it for workforce planning, headcount reporting or checking applicable-large-employer status. FTE is total weekly hours divided by the hours of one full-time schedule; the ACA count uses the IRS rule (30 hours a week is full-time, other employees count their monthly hours up to 120 each, divided by 120). Returns both counts; assumes every month looks like the one entered.

Find how long a shift or interval lasts between a start and an end written in military (24-hour) time, including shifts that run past midnight (2200 to 0630 is 8 hours 30 minutes). An end at or before the start counts as the next day. Returns hours and minutes and decimal hours for timesheets. Use military_time_convert to translate a single time between 24-hour and AM/PM, and time_duration_between when the two moments have different dates or a time zone with daylight saving.
