About this tool
WFH cuts commute (gas + wear), lunch (eat at home), parking, work clothes, and time. Studies show 60-90 min average commute round-trip. WFH reclaims 5-7 hours/week. The financial savings often exceed $10K/year for urban workers.
Bloom-Barrero-Davis Survey of Working Arrangements puts the average US WFH-day cost saving at $47 (commute, food, child care offsets), validated across 30,000+ workers in 2024-2025. Apply that to 2 WFH days per week and you free up roughly $4,900 per year before tax-deferred 401(k) auto-escalation kicks in. Offsets to weigh on the other side: home utilities rise $40-100/month, broadband may need upgrading, and an ergonomic chair plus desk adds $400-1,200 in year one.
How it works
Worked example: 25-mile round-trip at 28 mpg and $3.30/gal gas costs $2.95 in fuel; $12 daily lunch out vs $4 at home saves $8; $20 daily parking. Per WFH day = $30.95. Over 48 weeks at 2 WFH days/week (96 days) = $2,971/year, before factoring 50 reclaimed commute hours valued at after-tax wage. Add IRS 70 cents/mile full TCO and the gross saving exceeds $5,000/year for a 25-mile commuter.
Frequently asked questions
How accurate is the Work From Home Savings Calculator?
It applies the standard formula. Accuracy is limited only by your input precision. For decisions with material consequences (taxes, medical, legal, structural), use the result as a starting point and verify with a qualified professional in the relevant field.
Is the Work From Home Savings Calculator free to use?
Yes. 100% free, no signup, no payment, no API key. The site is funded by display ads around the tool but not inside the calculation flow.
Are my inputs saved anywhere?
No. All inputs stay in your browser tab. Closing the tab discards them. The site uses Google Analytics for traffic measurement (anonymized) but the analytics never see what you type into the form.
Can I use the Work From Home Savings Calculator on my phone?
Yes. The tool is responsive and tested on iOS Safari, Android Chrome, and major desktop browsers. Touch targets meet Apple's 44pt and Google's 48dp minimum.
Does the Work From Home Savings Calculator work offline?
Yes. Once the page has loaded, it works without internet. The calculation runs in JavaScript on your device.
How do I report a bug or suggest improvement to the Work From Home Savings Calculator?
Email hi@3tej.com with the URL of this page and a description of what you saw vs expected. We typically respond within 72 hours.
Can I share results from the Work From Home Savings Calculator?
Take a screenshot or copy the output. The page doesn't generate shareable URLs for specific calculations - inputs stay in your browser only.
Why are the results different from another work from home savings tool?
Most likely: different formula assumptions, different default values, different rounding rules, or different applicable rates. Check the methodology if both tools document it. Both can be valid for different scenarios.

Can I deduct home office expenses on my 2026 US taxes?
If you are a W-2 employee, no, the 2017 Tax Cuts and Jobs Act eliminated the miscellaneous itemized deduction for unreimbursed employee expenses through 2025 and that provision is widely expected to extend in the 2026 tax-reform package. Self-employed and 1099 contractors can still use Form 8829 or the $5/sqft simplified method up to 300 sqft ($1,500 max).
What hidden WFH costs should I track?
Track utilities (electricity up 15-25% on full-WFH days), broadband upgrade fees, ergonomic equipment depreciation, and subscription overlap (you may still pay for corporate parking spots). One-time setup of $1,000-2,000 typically pays back inside year one for daily WFH workers.
How to use the Work From Home Savings Calculator
The Work From Home Savings Calculator is a browser-based tool that runs entirely on your device. Inputs you enter never reach a server - all calculations happen client-side in JavaScript. This means:
- Privacy: nothing is logged, sent, or stored by 3Tej. Inputs disappear when you close the tab.
- Speed: results update as you type. No network round trip.
- Offline use: once the page is cached, it works without internet.
- No signup: no account, no email, no rate limits.
Step by step
- Enter your inputs in the form above. Each field is labeled with its unit (currency, percent, kg, etc.) and the expected range.
- Read the result as it updates. The number reflects the formula commonly accepted in Work From Home Savings-related calculations.
- Adjust to see sensitivity: change one input at a time and watch how the output moves. This is the fastest way to understand which variable matters most.
- Copy or screenshot the result for later reference. The page state persists for the session if your browser allows it.
When you would use this
- Quick estimates: when you need a number now and don't want to open a spreadsheet.
- Sensitivity analysis: testing how a result changes as inputs vary, before committing to a real-world decision.
- Comparison: running the same calculation with different inputs to compare options side by side.
- Learning: building intuition for how the underlying math behaves.
- Documentation: capturing a snapshot of inputs and outputs at a point in time.
