Biweekly Time Card Calculator
Total two weeks of shifts at once — with a subtotal for each week and a combined pay-period total.
Plenty of employers run a two-week pay period, so a single weekly time card means adding two of them together. Fill in your clock-in and clock-out times (and each day’s break) across both weeks and this calculator gives you a subtotal for week one, a subtotal for week two, and the combined biweekly total — in hours and minutes and in the decimal hours payroll uses. Leave any day blank and it counts as a day off.
How this calculation works
- 01For each day, convert clock-in and clock-out into minutes and subtract that day’s unpaid break.
- 02Add the seven daily totals in each week to get that week’s subtotal.
- 03Add the two weekly subtotals together for the biweekly pay-period total.
- 04Divide the total minutes by 60 for decimal hours.
- —Each week is subtotalled separately, which mirrors how biweekly pay stubs usually break the period down.
- —Any day left without a clock-in or clock-out is treated as a day off (zero hours).
- —Breaks are per-day and unpaid — set a day’s break to 0 if it was paid.
- —Overnight shifts are handled per day, and the two-week total is a plain sum with no overtime multiplier applied.
Worked examples
Two identical Mon–Fri weeks, 09:00–17:00 with a 60-min lunch
35h 00m + 35h 00m = 70h 00m (70.00 decimal hours)
Week 1 four 10-hour days; Week 2 five 8-hour days, 30-min breaks
38h 00m + 37h 30m = 75h 30m (75.50 decimal hours)
Week 1 full-time; Week 2 three days off
40h 00m + 16h 00m = 56h 00m (56.00 decimal hours)
Frequently asked questions
- How do I calculate a biweekly time card?
- Total each week the usual way — subtract clock-in from clock-out and take off breaks for each day, then add the days — and finally add the two weekly totals together. This calculator shows both weekly subtotals and the combined two-week total automatically.
- What is the difference between a weekly and biweekly time card?
- A weekly time card covers seven days; a biweekly one covers a full 14-day pay period. Biweekly is common because many employers pay every two weeks, so this calculator keeps each week’s subtotal visible while giving you the combined figure to submit.
- Does it handle overtime across the two weeks?
- It sums the exact hours worked without applying an overtime multiplier, since overtime rules vary by region and are often calculated per week. Use the per-week subtotals as the basis for any overtime your rules require.
- Is there an easier way than filling this in every pay period?
- Yes — InstaClock records your hours as you work and keeps the running weekly and pay-period totals, so at the end of two weeks the number is already there instead of reconstructed from memory.
