Office Days Cost Calculator
Enter required office days, one-way commute, and the lunch difference versus a remote day. The calculator builds a per-day premium (commute×2, lunch, other, time value, clothes) and multiplies by days per year. At 3 days/week, 35 minutes, lunch 45 vs 20, other 15, rate 60, and 46 weeks, the yearly premium is about 23,058. The result compares an office day to a remote day — it does not judge company policy.

Return-to-office debates usually focus on productivity and culture. This calculator measures something else: how much extra a required office day costs versus a remote day. The result is not a verdict that the office is bad and remote work is good. It shows costs that often sit outside a salary band.
This is an estimate of the office-day premium versus a remote day. Years on one commute are on the commute cost page. You can take an hourly rate from the rate from pay calculator.
How this estimate works
The calculator builds an office-day premium from round-trip commute, lunch gap versus a remote day, other day costs, monthly clothes allocated across office days, and optional time value (commute plus prep minutes × hourly rate). Year = day premium × (days per week × weeks per year).
Presets 1 / 2 / 3 / 5 only set office days; weeks stay put. At 3×46 you get 138 days; at 5×46, 230. Check “Compare hybrid” and the result also shows a 5-day scenario at the same unit costs plus yearly savings versus full office.
Example 1: 35 min and 8 one-way commute, lunch 45 vs 20, other 15, clothes 150 / month, prep 40 min, hour worth 60 → about 23,058 a year. A cost sketch, not a judgment of company policy.
Article hook: the offer says “3 office days” and the salary band is silent on commute. At 35 minutes one way, lunch 45 vs 20, and an hour worth 60, the premium is about 23,058 a year — before you compare against five days. A cost sketch, not a verdict that offices are bad.
Formula
day_premium = commute×2 + (office_lunch − remote_lunch) + other + (commute_min×2 + prep)/60 × hourly + clothes_month / office_days_year
year_premium = day_premium × (days_week × weeks)
Hybrid: same day premium at your days and at 5 days; gap = full office − hybrid. At 3×46, 35 min, lunch 45 vs 20, other 15 and $60/h ≈ 23,058 / year.
FAQ
Which fields are required to start?
Office days per week, weeks per year, and one-way commute time. Lunch, clothes, and hourly value sit in options and may stay empty.
What do the 1 / 2 / 3 / 5 day buttons do?
They set office days. At 3 days and 46 weeks that is 138 days a year; at 5 days — 230 days with the same weeks.
What does the hybrid comparison do?
With the same day costs it computes your result and a 5-day office scenario, then shows the annual difference. Full remote in the model is 0 days × the same units.
Where does about 23,058 in example 1 come from?
The day from commute, lunch gap, other 15, clothes, and time value × 138 days. Example 1 numbers: 3 days, 46 weeks, 35 min, 8, lunch 45 vs 20, clothes 150, prep 40, value 60.
Does the result judge company policy?
No. It estimates the on-site day premium versus a remote day. It is not HR or career advice.
What if home lunch is more expensive?
A negative lunch gap lowers the net “office price”. The food category bar then does not show a positive penalty.
How is time value counted?
Round-trip commute minutes plus prep, divided by 60, times the hourly rate. At 70 min commute, 40 prep, and 60/h that is 110 of time value per day.
Why monthly clothes?
The monthly amount is divided by office days in the year and added to the day. At 150 and 138 days that is about 1.09 per day.
Is one-way commute doubled?
Yes. Commute cost and time in the model are round-trip: the field × 2.
How many weeks per year should I set?
Typically 46–48 after leave. 52 means every week with no break — rarely realistic.
Does the result include a work phone plan?
Not unless you enter it under other day costs. The model does not invent subscriptions.
How is this different from commute cost over years?
Here the office-versus-remote day balance (lunch, clothes, time). Commute alone over a multi-year horizon belongs on the commute-cost page.
How is one office-day cost counted?
Commute, meal difference, clothes, prep, and extras divided by office days per year, plus a money value of commute time.
What does the hybrid day share do?
It reduces office days per year. At 50% hybrid, fixed and commute costs scale with days on site.
Why enter an hourly value?
It turns commute minutes into money. At 60 minutes a day and $50/h that prices your travel time.
Is remote food subtracted from office food?
Yes. The calculator uses the difference so you do not double-count “I would eat anyway”.
What do the 5- and 10-year scenarios show?
They multiply the annual cost by 5 or 10. Simple projection, no inflation.
Is the result career advice?
No. It is the sum of your fields. Hybrid decisions stay with you and your employer.
How are weeks per year used?
You can set e.g. 46 to exclude vacation. The calculator multiplies days/week × weeks.
What about clothes and prep?
Those annual or monthly amounts are spread across office days to show the cost of a day on site.
How do I calculate the yearly cost of office days?
Compute one day’s premium versus a remote day, then multiply by days/week × weeks. At 3×46, 35 min, lunch 45 vs 20, other 15, and 60/h the yearly figure is about 23,058.
What changes at 5 office days instead of 3 with the same day costs?
With the same per-day units, a 5×46 schedule has more presence days than 3×46; the hybrid compare shows the yearly gap between full office and your rhythm.
Is this the same as a fuel-only commute calculator?
No. Here the day balance includes lunch, clothes, and time value. Fuel mileage alone belongs on the commute-cost page.
