Tardy Calculator Form
Use the fields below to evaluate late arrivals, grace rules, rounding policy, attendance points, and estimated payroll impact.
Formula Used
This model treats early arrivals as zero tardy minutes. If the actual time looks like a post-midnight clock-in, the calculator adjusts for overnight shifts automatically.
How to Use This Calculator
- Enter the employee name and department for reporting clarity.
- Input the scheduled shift start and the actual clock-in time.
- Add the grace period defined by your attendance policy.
- Set the rounding increment used by your organization.
- Provide the hourly rate to estimate lost pay.
- Enter previous tardies, policy points, and the monthly threshold.
- Click Calculate Tardy to show the result above the form.
- Use the CSV or PDF buttons to save the report.

FAQs
1. What is a tardy calculation?
A tardy calculation measures how late an employee clocks in against the scheduled start. It can also apply grace periods, rounding rules, attendance points, and estimated pay impact for consistent policy enforcement.
2. Does the calculator subtract a grace period first?
Yes. Raw lateness is reduced by the grace period before rounding is applied. This helps align the result with attendance policies that forgive a small number of late minutes.
3. How does rounding affect tardy minutes?
Rounding moves chargeable tardy minutes up to the next policy increment. For example, 7 chargeable minutes rounded to 5-minute increments becomes 10 minutes.
4. Can this calculator estimate lost pay?
Yes. It converts rounded tardy minutes into hours and multiplies them by the hourly rate. That produces a simple estimate for payroll impact or unpaid attendance time.
5. What happens if the employee is early?
Early or exact clock-ins return zero tardy minutes. The calculator does not create a tardy event when the actual time is equal to or earlier than the scheduled start.
6. Is this useful for disciplinary thresholds?
Yes. The tool compares total tardies this month against the maximum allowed threshold and labels the result as on time, coaching, warning, or escalation range.
7. Can it work for overnight shifts?
Yes. If the actual clock-in appears to be after midnight and earlier than the scheduled time, the calculator can treat it as an overnight shift rather than a negative result.
8. When should HR use the projected monthly loss value?
Use it as a planning estimate only. It assumes the same tardy pattern repeats across all entered workdays in the month, so it is best for forecasting rather than final payroll processing.
