Example 1
- 3 days a week
- 35 min commute plus lunch
- 5-year horizon
≈ a typical hybrid extra
Three days give a visible extra from commute and lunch before clothes stack on.

Office days cost calculator
The calculator uses the numbers you enter: required office days per week, a one-way commute, and what lunch costs in the office versus at home. With 3 days a week, a 35-minute one-way trip, lunch at 45 versus 20 at home, and 46 work weeks, the extra cost is 23,058 a year. The result compares an office day with a remote day. It does not judge company policy.
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.
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.

How this estimate works
Office price is the gap between a required on-site day and a remote day. 3 days and 46 weeks are 138 office days a year. A 35-minute one-way trip is 70 minutes round trip; 8 one-way is 16 a day. Lunch 45 minus 20 at home is 25. Prep 40 minutes and 60 an hour put 110 of time value on the day. Clothes 150 a month spread over 138 days, about 1 a day. The day is about 167, the year 23058.
Five days, a 50-minute one-way commute, and a larger lunch gap raise the yearly total, because days rise to 240 at 48 weeks. One day a week gives a small extra cost. Two short days and a cheap 20-minute trip stay low before clothes are added.
Commute plus prep also show as hours: (70+40)/60 is about 1.83 hours a day, about 253 hours a year at 138 days. Full days divide those hours by 24, waking days by 16. Scale, not a health claim.
Clothes are spread evenly across office days in the year. That is a simplification. Parking or care goes in other office-day costs. If the hourly value is 0, only cash remains: at 5 days, 45 minutes, and lunch with no time value, the sum is lower than with 60 an hour.
Fields: days per week, weeks, one-way minutes, one-way cost, office and remote food, clothes, prep, other costs, optional hourly value, and 5- and 10-year horizons. The horizon multiplies the year. 23058 times 5 is 115290, with no inflation.
The calculator does not judge a return-to-office policy. Mentoring and the upside of being on site stay outside the model. When you quote a result, name the days, one-way minutes, and whether you priced an hour. Years spent on one commute are on the commute-cost page.
How to read your result
- “Office days cost” is the gap between a required on-site day and a remote one: commute, food, clothes, prep time, other costs, and an optional time value.
- We build the annual total from your office days per year (days/week × weeks/year).
- The result isn’t a judgment of company policy: it just surfaces costs that often sit outside your salary band.
What drives office-day cost the most?
- Commute: round-trip time and cash, especially on longer routes.
- Food & coffee: the office-vs-remote gap is often bigger than “just lunch”.
- Clothes & prep: a monthly wardrobe budget spread across office days, plus getting-ready time.
- Other costs: parking, childcare, extra tickets — often missing from return-to-office debates.
- Time value: once you price an hour, commute and prep become real money.
Assumptions behind this calculator
- We compare required office days with a remote baseline at the same number of work weeks.
- Monthly clothes spend is spread evenly across office days in the year: a simplification.
- “Full days” and “waking days” are time scales (÷24 / ÷16), not lifespan claims.
- This isn’t HR, tax, or negotiation advice: just a tool for building your own cost picture.
How to use
- Type required office days per week and weeks per year. 3 and 46 is 138 office days.
- Type the average one-way commute time and cost: 35 minutes and 8. The calculator doubles both values, because it counts the trip both ways.
- Add office and remote food, monthly clothes, prep minutes, and other day costs.
- Optionally type an hourly value so commute and prep enter the money sum. In the first example that value is 60.
- Click Calculate. With those numbers the premium is 23058 a year. A 5-year horizon shows 115290.
Days, commute, and office lunch
An on-site day minus a remote day. 3 days, 35 min one-way, and lunch 45 at 46 weeks give 23058 a year.
- days
- Required office days in the week. 3 days and 46 weeks is 138 days. A 5-year horizon multiplies the yearly premium.
- commute
- One-way time and cost. 35 min becomes 70 min a day. A cost of 8 becomes 16 a day.
- lunch
- Food spend on an office day. 45 versus 20 at home is +25 a day, part of 23058 in the year.
Sample profiles
Example 2
- 5 days, longer commute
- Parking in other costs
- 5 and 10 years
≈ a strong horizon effect
Five days come out much higher, and a decade multiplies that extra without inflation.
Example 3
- 2 days, short commute
- Low lunch gap
- No long horizons
≈ a smaller extra, still visible
Two days give a lower yearly total, but the commute still comes out above zero.
Example 4
- 4 days, 40 min
- Clothes 180
- 5-year horizon
≈ closer to a full week
Four days give an extra closer to five than to two, because commute and lunch return more often.
Example 5
- 1 day a week
- Short commute
- Low clothes
≈ the smallest extra here
One day comes out cheap versus five office days, still with lunch and the trip.
Example 6
- 5 days, 70 min
- High hourly value
- 10-year horizon
time ≈ a large share of the total
A long commute times an hourly rate gives a large line beside lunch cash.
Example 7
- 3 days, 15 min
- Tiny food gap
- Low hourly value
≈ extra mostly from small lines
A short trip and similar food give a small extra; clothes can still lift it.
Example 8
- 5 days, 45 min
- Hourly value 0
- Clothes 120
cash ≈ without pricing hours
Zero in the rate leaves cash only: commute, lunch, clothes, no price on time.
FAQ
What do I get at 3 days, 35 minutes, and lunch 45?
138 days, about 167 a day with time at 60, and 23058 a year. Five years is 115290.
Do I type one-way or round trip?
One-way. 35 minutes becomes 70 minutes a day. A cost of 8 becomes 16 a day.
Where does 23058 a year come from?
Commute 16, lunch +25, other 15, time 110, and clothes about 1 a day, times 138 days, plus 150 of clothes in the year.
Does this judge company policy?
No. We compare an on-site day with a remote day at the same weeks. The calculator does not count mentoring or the upside of being on site.
How is the clothes cost spread?
Monthly 150 is divided by office days in the year. At 138 days that is about 1 a day, 150 a year.
What if the hour is blank or 0?
Cash remains: commute, lunch, clothes, and other. At 5 days and 45 minutes with no time value, the sum is lower than with 60 an hour.
How many hours at 3 days, 35 minutes, and 40 minutes of prep?
About 1.83 hours a day and 253 hours a year. Divided by 24 that is about 10.5 full days.
Does parking go in commute or other costs?
If it is a fixed office-day fee, other costs are easier. Commute is one-way times two.
Why a 10-year horizon?
It multiplies the yearly premium. 23058 times 10 is 230580. No inflation and no day-count change in year five.
How is this different from commute cost?
That page tracks years on one trip and compares days. Here an office day also has lunch, clothes, prep, and other costs versus a remote day.
