Remote vs Office Hybrid Savings Simulator: What Working From Home Really Saves
Executive industry analysis
Moving from a full-time office to a hybrid or remote model is often presented as a saving. The rent on empty desks is easy to see and easy to cut, and commute allowances go away. But the same decision adds costs that were never in the old budget: home-working stipends, collaboration tools, travel for in-person weeks, and a change in how efficiently people work together. Whether the policy pays depends on the balance of both sides, not on the rent alone.
The structure of the problem is a trade between two groups of costs. On one side are office costs that fall as more people work remotely: rent, utilities and commute subsidies, plus the value of keeping people longer. On the other side are costs that rise with remote days: allowances, software, travel and any loss of productivity. Productivity is the largest item in most cases, because it is priced at the loaded cost of every employee, and a small percentage applied to a large payroll quickly exceeds the rent saved.
The domino cascade starts with the share of the desk bill released. More remote days free more space, which raises gross savings. The cost of supporting remote work per person rises at the same time, and the productivity drag grows with the share of the week spent away from the office. Savings minus those costs is the net result, so the policy can move from clearly positive to negative if the productivity effect rises even a few points.
The iceberg shows what the rent figure hides. Above the waterline sit the three savings that are easy to count: the rent and utilities released, the commute stipends no longer paid and the replacement cost avoided if people stay longer. Below it sit four costs that rarely appear in the business case: output lost on remote days, home-working stipends, collaboration and security tools, and the travel and offsites needed to keep teams connected. The hidden part can be as large as the rent saving.
Formula and methodology blueprint
The model works per month. The share of the week spent remotely is remote days divided by five. Rent saved is headcount times the cost per desk times that share times a realisation factor, because leases and meeting rooms limit how much space can really be released. Commute stipends saved are priced per head. Retention savings come from a small fall in turnover for each remote day, priced at half a year of loaded cost per avoided leaver. Costs are stipends, tools, the productivity effect on loaded payroll and offsites.
- Remote share
- r = remote days ÷ 5
- The share of the working week spent away from the office.
- Rent saved
- S = headcount × rent per desk × r × 0.8
- Rent and utilities released, limited by lease terms and shared space needs.
- Retention saving
- R = headcount × remote days × 0.3% × 0.5 × loaded cost
- Avoided leavers per year times the replacement cost, spread over twelve months.
- Productivity drag
- P = headcount × loaded cost × r × productivity loss
- The value of output lost on remote days, priced at the loaded payroll.
- Net saving
- Net = S + commute + R − stipends − tools − P − offsites
- The monthly result. The breaking point is the productivity loss or remote-day count where it reaches zero.
Cascading elasticity
Productivity loss is the most elastic input because it is priced on the whole payroll, which is far larger than the rent. Remote days increase both savings and costs, so their effect depends on which side is larger at your inputs. Rent per desk is linear and matters most in expensive cities, while the stipend is small per head but grows with the remote share.
Three real-world case studies
Bootstrapped starter
A small team in a pricey office
A twelve-person team in a costly city moves to two remote days a week with a small stipend and little productivity loss. Rent savings outweigh the new costs, but only slightly. Load it to see how thin the margin can be at small scale.
Scaling mid-market
A large company with expensive space
A company of a hundred and eighty people at a high cost per desk goes to three remote days a week with a low productivity penalty. The rent saved across hundreds of desks makes the policy clearly positive. Load it to see how scale and a high desk cost help.
Black-swan crisis
Cheap office, heavy remote policy, weak collaboration
A team with inexpensive office space moves to four remote days, pays large stipends and sees a big productivity loss. The rent saved is small while the output lost is large. Load it to see why remote work is not a saving when the office is cheap.
Industry benchmark matrix
| Metric | Danger zone | Industry average | Top 10% elite |
|---|---|---|---|
| Office cost per desk as share of loaded cost | Below 4% | 6–9% | Above 12% |
| Productivity loss on remote days | Above 10% | 2–5% | Below 2% |
| Desk utilisation before the change | Above 80% | 50–65% | Below 40% |

Variables and levers
Headcount
Number of employees affected by the hybrid or remote policy.
Lever: Apply the policy where the saving per head is largest and the work suits remote collaboration.
Office cost per desk per month
Rent, utilities, cleaning and service charges divided by the number of desks.
Lever: Release space only when a lease allows it, and sublet or renegotiate rather than paying for empty desks.
Remote days per week
Days each employee works from home in an average week.
Lever: Pick a remote-day pattern that matches the work and fix the anchor days so teams meet in person on the same days.
Home-working stipend per month
Allowance paid to each fully remote employee for internet, energy and furniture.
Lever: Replace flat allowances with a clear, capped stipend that covers the real extra cost.
Productivity loss on remote days
Drop in output on remote days compared with office days, from coordination and slower collaboration.
Lever: Invest in written processes, shared documents and clear ownership so remote days do not slow decisions.
Loaded cost per person per month
Salary plus employer costs for one employee, used to price lost output and turnover.
Lever: Price productivity and retention effects with the true loaded cost, because they scale with every salary.
How to use this simulator
- 1Start from the realistic preset or enter your headcount, desk cost and planned remote days.
- 2Set the loaded cost per person, because it prices productivity and retention.
- 3Enter a cautious productivity loss, based on a trial or on your own measurement.
- 4Press Find my breaking point to see which input erases the net saving first.
- 5Compare the current policy with the focus-day plan over 24 months in the Parallel universe tab.
Mistakes to avoid
- Counting the rent but not releasing the space. If the lease cannot be reduced, the saving exists only on paper.
- Ignoring productivity because it is hard to see. A small loss across the whole payroll can exceed the entire rent saving.
- Assuming everyone benefits equally. Juniors, new hires and collaborative teams often lose more on remote days than experienced individual contributors.
- Treating stipends as one-off. Allowances recur every month and grow with the remote share, so budget them as a running cost.
Frequently asked questions
Is remote work always cheaper than an office?
No. Remote work removes some costs and adds others, and productivity effects can outweigh the rent saved. It tends to pay when office space is expensive and collaboration is well organised.
Why is productivity priced on loaded cost?
Because a loss of output costs the business what the lost hours would have produced, and loaded cost is a cautious proxy for it. Use your own estimate if you can measure output.
How is retention included?
The model assumes a small fall in yearly turnover for every remote day per week and prices each avoided leaver at half a year of loaded cost. Treat it as a cautious assumption, not a promise.
What about commuting time, taxes and legal rules?
Rules on home-working allowances, working time and tax treatment differ by country and change. Check current rules before you design a policy.
How do I find the breaking point?
Press Find my breaking point. The tool pushes each input to its worse end in small steps and reports the value at which the net saving reaches zero.
