This is a cost comparison of entered cash flows. It does not determine ISO 41001 or 41012 conformity, service quality, statutory staffing or inspection, labour or contracting compliance, tax or accounting treatment, or vendor suitability. Primary sources were checked on 2026-08-04.
Integrated facility management combines technical maintenance, soft services such as cleaning and security, operating administration, and specialist-vendor coordination within one management system.
An outsourced contract may bundle many of those activities, but retained governance, pass-through charges, excluded work, and service-failure exposure do not disappear.
An in-house model can preserve direct control and site knowledge, but it carries more than payroll: relief labour, specialist contracts, systems, equipment, materials, and disruption exposure also belong in the comparison.
This calculator puts both alternatives on one horizon and discount-rate basis, then reports nominal and present-value total cost of ownership.
Its purpose is to avoid comparing a vendor quote with bare salary while leaving different scopes and retained costs hidden.
Every default price, staffing level, and area is a fictional worked example, not a market benchmark, compliant staffing level, or vendor quote.
Pass-through, excluded scope, retained governance time, and expected service-failure cost in outsourced TCO
Relief labour, specialist contracts, systems, equipment, capital reserve, and expected disruption cost in in-house TCO
Initial, monthly, periodic, and terminal cash flow placed at its timing before PV and equivalent-cost comparison
A TCO result is useful only when the outsourced proposal and the in-house operating plan cover the same facilities, hours, and performance level.
If a vendor offers round-the-clock technical response while the internal plan has weekday daytime coverage, a lower figure represents a different service rather than a true saving.
Align cleaning frequencies, security posts, preventive-maintenance cycles, statutory-inspection support, help-desk response, energy management, and minor-work approval limits line by line.
| Comparison axis | Check in the outsourced case | Check in the in-house case |
|---|---|---|
| Work scope | Included, pass-through, and excluded tasks | Directly performed and subcontracted tasks |
| Operating coverage | Resident staff, on-call cover, and surcharges | Shifts, holidays, leave cover, and overtime |
| Performance | KPI, SLA, and service credits | Internal targets, audits, and correction |
| Risk allocation | Indexation, subcontracting, liability, and insurance | Vacancies, incidents, obsolescence, and purchasing |
If cleaning materials and after-hours callouts are included in the outsourced base fee, do not repeat them under pass-through or excluded scope.
If loaded FTE cost already contains ordinary benefits and employer burden, use relief labour only for incremental overtime and vacancy cover.
Treat capital reserve as cash set aside for future replacement, and do not repeat the same replacement in monthly systems cost and a periodic renewal event.
Expected loss should be a monthly probability-weighted net amount after estimated insurance or service-credit recovery, not the gross consequence of one severe event.
Outsourced monthly cost adds the base fee, area multiplied by area rate, pass-through, excluded-scope cover, retained hours multiplied by loaded hourly cost, and expected service-failure loss.
In-house monthly cost adds loaded FTE by role, relief labour, specialist contracts, systems and equipment, area-linked materials, oversight outside the FM team, expected disruption, and capital reserve.
Annual escalation changes recurring cost in 12-month steps, while initial cost sits at month zero, operations at each month-end, rebid or renewal at the selected month, and net terminal cost at the end.
The annual discount rate is converted to an effective monthly rate before every cash flow is discounted from its timing.
Recoverable in-house residual value reduces terminal cost but cannot exceed setup plus periodic renewal cost actually included within the horizon.
Monthly discount rate = (1 + annual rate)1/12 − 1
PV TCO = initial cost + Σ(monthly cash flow ÷ (1 + monthly rate)month)
Outsourcing NPV = in-house PV TCO − outsourced PV TCO
The lower PV TCO is shown as the lower-cost case, and equivalent monthly cost uses the same monthly discount basis.
Per area-month, per facility-month, and per facility operating hour are normalization metrics for portfolios of different scale.
Area, outsourced base-fee, and total in-house FTE break-even results hold every other input fixed, so they are not market prices or staffing recommendations.
A cumulative crossover is linearly interpolated between two month-end balances and reported only when the new ranking persists through the horizon.
The timing and life-cycle cost structure draws on the official NIST Handbook 135e2022 page.
The management-system and strategic sourcing scope draws on the official descriptions of ISO 41001:2018 and ISO 41012:2017.
The treatment of assumptions, sensitivity, and traceable cost elements also considers the GAO-20-195G Cost Estimating and Assessment Guide.
These sources support method and scope, not local market pricing or compliance in a particular jurisdiction.
The official pages were checked on August 4, 2026.
The English defaults assume one 215,000 ft² commercial facility, a 60-month horizon, and a 4% annual discount rate.
First-year monthly operating cost is USD 122,100 for outsourced FM and USD 163,000 for in-house management.
After escalation, a month-36 rebid or renewal, and terminal cash flow, nominal TCO is about USD 7,824,946 outsourced and USD 10,731,983 in-house.
PV TCO is about USD 7,078,713 outsourced and USD 9,727,893 in-house, producing a fictional outsourcing NPV of about USD 2,649,180.
Equivalent monthly TCO is about USD 130,137 outsourced and USD 178,840 in-house, with a PV difference of about 31.53% against average PV.
| Metric | Outsourced integrated FM | In-house management |
|---|---|---|
| First-year monthly operating cost | USD 122,100 | USD 163,000 |
| Nominal TCO | USD 7,824,946 | USD 10,731,983 |
| Present-value TCO | USD 7,078,713 | USD 9,727,893 |
| Equivalent monthly TCO | USD 130,137 | USD 178,840 |
These defaults exist to explain and test the model, so they are not a procurement or investment conclusion.
Area, coverage, workforce structure, retained scope, transition feasibility, tax, and contract terms can reverse the result.
Replace every fictional amount with at least two comparable vendor quotes and documented internal cost from the same pricing date.
Area break-even changes only the area-linked rates.
Base-fee break-even is the outsourced monthly base fee that equals the current in-house cash flow.
Total FTE break-even preserves the entered role mix and each loaded role cost while scaling headcount proportionally.
A value obtained without reviewing coverage, shifts, and required competence is not a staffing plan.
A case with greater setup cost can have lower recurring cost while remaining more expensive in early months.
Sustained crossover shows when the lower cumulative PV case changes and stays changed through the horizon.
No crossover may mean that one case was always lower or that a temporary reversal did not persist, so inspect the annual table as well.
These cases are probability-free what-if calculations rather than a forecast distribution.
A stable ranking across all four indicates more cost headroom, while a quick reversal means service quality and risk allocation deserve greater weight than a narrow price difference.
Comparison of outsourced mobilisation with in-house recruitment and system setup against one opening schedule
A baseline including pass-through, exclusions, retained contract management, and exit or transition rather than the base fee alone
A test of simple payroll-saving claims against workforce transfer, specialist contracts, and capabilities that remain external
Common governance separated from site cost with per-site and per-area normalization for scale effects
Nominal budget and PV economics shown separately, including renewal, exit obligations, and recoverable residual value
Conditional fee break-even and scope-gap stress used as boundaries without permission to reduce required service
Licensing, qualifications, designated roles, inspections, labour, contracting, privacy, and security duties depend on jurisdiction and actual scope.
This calculator does not determine whether those duties apply or have been met, so confirm them with the relevant authority and legal, labour, and safety specialists.
Referring to an ISO standard does not mean that an organization or supplier is certified or conformant.
Separate base, area, pass-through, and excluded scope whenever possible; a grand total hides which cost varies with use and which exposure remains with the owner
No; use loaded cost that includes employer burden, benefits, recruitment, training, and ordinary workforce overhead, while keeping incremental overtime and vacancy cover under relief labour
If the owner pays the same utility amount under either model, exclude it as a common non-differential cost; if performance incentives or markup create different net cash flow, enter only the difference in the relevant pass-through or operating line
No; this is a pre-tax comparison of entered operating cash flow, while depreciation, corporate tax, recoverable indirect tax, and financing require a separate model aligned with organizational accounting policy
No; evaluate compliance, safety, resilience, occupant experience, supply chain, data ownership, innovation capability, and reversibility in a separate non-price scorecard
Match the actual contract or organization decision and include material renewal; short horizons overemphasize setup, while very long horizons depend heavily on uncertain escalation and residual value, so compare multiple horizons
A strong TCO model is not the one with the most numbers; it is the one where scope, pricing date, cost owner, and evidence can be checked again.
Replace fictional defaults with the site RFP, workforce plan, and operating history, then reconcile the cost breakdown to quotes and budgets.
Document how the conclusion changes between the base and stress cases, and carry both cost and service-risk evaluation into the decision record.
