To compare working from home with going to an office, use the same workdays and take-home pay assumption, then count only cash costs that actually change. Remote work may add electricity, internet or equipment spending while removing commute costs. Neither arrangement is automatically cheaper, and saved travel time is not cash in your account.
The CFPB spending-tracker guidance recommends looking at actual spending before changing a budget. Its page is archived; use the method, not as a statement of current employment or tax rules. Keep any employer-provided equipment, allowance or reimbursement as a documented input to your own comparison rather than assuming everyone receives it.
Make two columns with matching assumptions
- Remote fixed monthly changes: any extra internet plan cost, work-only service, and an estimate of incremental electricity or heating/cooling. If a bill does not change, do not charge the entire household bill to work.
- Remote per day: home meals or work supplies you would not otherwise buy.
- Office fixed monthly changes: parking pass or other recurring work-related charge.
- Office per day: round-trip transit fare or incremental driving cash, tolls, per-day parking and comparable meals. Avoid double-counting a parking pass and a per-day fee for the same space.
- One-time cash: desk, chair or setup purchases needed specifically for one arrangement. Spread these only for a chosen comparison period; the full amount is still due when bought.
For devices running at a steady draw, electricity use in kWh is watts divided by 1,000, multiplied by operating hours per day and the number of days. The EIA explains watts versus kilowatthours. Actual appliance draw, heating/cooling and utility rate vary; a device estimate does not forecast the whole power bill. As a hypothetical input, 125 watts for 8 hours on 20 days is 20 kWh; at an illustrative $0.20 per kWh, that is $4 of variable energy, not a current local tariff or a guaranteed bill increase.
Worked comparison: 20 workdays
| Line | Fully remote | Fully office |
|---|---|---|
| Monthly fixed change | $20 extra internet + $4 electricity = $24 | $70 parking pass |
| Per workday | $5 home lunch | $10 round-trip travel + $5 packed lunch = $15 |
| 20-day recurring cash | $124 | $370 |
| One-time setup spread over 12 months | $240 desk ÷ 12 = $20 | $0 |
| Monthly comparison equivalent | $144 | $370 |
Remote is $226 lower per month in this narrow hypothetical comparison after allocating the desk over 12 months. The $240 desk purchase still requires $240 in cash when purchased. The meal cost is deliberately the same $5 for home lunch and packed office lunch; the modeled difference comes from travel, parking, internet, device energy and the desk. Other work-related spending, heating/cooling, vehicle wear, childcare, insurance, compensation and benefits could change the result. Do not use these example amounts as local price quotes.
If the office trip takes an illustrative 45 minutes each way, 20 office days represent 1,800 minutes, or 30 hours of travel. Keep those 30 hours in a separate decision column. Do not multiply them by a wage and add the result to the $226 cash comparison unless you are explicitly modeling a separate, realistically earnable income opportunity.
Two-option cash cost comparison
Monthly equivalent = monthly fixed cost + cost per use × uses per month + one-off cost ÷ comparison months. Enter all applicable cash costs yourself. Assumes constant monthly costs. Excludes refunds and refundable deposits, time, taxes, wages, benefits, financing, and resale value. One-off amounts are spread for comparison, not a payment schedule.
US dollars. This tool calculates in your browser only. It does not send, store, or log your entries. Required fields are labeled below. Dollar entries allow up to two decimal places.
In the two-option tool, set remote fixed costs to $24 and per-use cash to $5; office fixed costs to $70 and per-use cash to $15. Use 20 workdays, 12 comparison months and a $240 remote one-off. This tool compares cash costs, not salary, hours, taxes, utility billing details or legal reimbursement rights. The rent-and-commute comparison is helpful if a housing move is also under consideration; a job-offer comparison should account for separately verified pay and benefits.
Replace the example with your own terms
Check your employer’s written equipment and reimbursement policy, the number of required office days, your utility bill and your actual trip cost. Test a hybrid schedule too: count remote and office days separately rather than assuming all 20 days use one setting. If you might switch jobs or schedules, choose a shorter comparison period for one-time purchases. This is a cash worksheet, not tax advice or an assertion of reimbursement entitlement.
