Zero-based budgeting — ZBB — Is a financial planning approach in which every expense must be evaluated and justified from a zero base at the start of each budget period, rather than being carried forward from the prior year with incremental adjustments. In hospitality, ZBB requires departmental heads to build their budgets from scratch, demonstrating the business case for each cost line against current operational needs, revenue targets and strategic priorities. The methodology is designed to eliminate legacy costs that persist through habit rather than merit, expose inefficiencies hidden within inflated baseline budgets and ensure that every pound of expenditure is aligned with the hotel's current commercial objectives.
Zero-Based Budgeting Explained
Traditional hotel budgeting is predominantly incremental: the finance team takes last year’s actual expenditure by department and cost category, applies an inflation factor or a management-directed percentage adjustment, and produces the new budget. This approach is efficient, it requires relatively little time from departmental managers, but it embeds a dangerous assumption: that last year’s spending structure was essentially correct. In reality, hotels accumulate cost layers over years that are never questioned. A marketing subscription taken out three years ago that nobody uses; a linen supplier whose contract was competitive when signed but has not been retendered in five years; a staffing model designed for a different occupancy mix; maintenance contracts for equipment that has been replaced. Incremental budgeting perpetuates these costs automatically because they are already “in the base” and nobody is asked to justify them.
Zero-based budgeting rejects the prior-year base entirely. Each department starts at zero and must construct its budget by identifying every activity it needs to perform, determining the resources required for each activity, costing those resources at current market rates and demonstrating how each cost contributes to revenue generation, guest satisfaction, regulatory compliance or operational necessity. The F&B department does not inherit last year’s £340,000 cost base and argue for or against adjustments; it must justify why it needs £340,000, or perhaps only £305,000, or perhaps £360,000, based on the specific activities planned for the coming period, the current cost of ingredients, labour, equipment and consumables, and the revenue those activities are expected to generate.
ZBB gained prominence in the hospitality industry when several major hotel groups adopted it as part of cost-transformation programmes following periods of margin compression. The methodology proved particularly effective at identifying what practitioners call “budget creep”, the gradual, invisible inflation of cost bases that occurs when departments routinely spend their full allocation (to avoid next year’s budget being cut) and when new costs are added without corresponding old costs being removed. ZBB forces a conversation that incremental budgeting avoids: not “how much more or less than last year?” but “should we be spending this money at all?”
The discipline is not without limitations. ZBB is significantly more time-consuming than incremental budgeting, requiring each department head to invest considerable effort in bottom-up cost justification. It can create organisational tension if managers perceive they must “fight” for resources they consider essential. And it is poorly suited to fixed costs that genuinely cannot be varied in the short term (rent, insurance, franchise fees). For these reasons, many hotel operators adopt a hybrid approach: applying full zero-base rigour to discretionary and semi-variable costs (marketing, training, maintenance, supplies, outsourced services) whilst budgeting truly fixed costs incrementally. This pragmatic application captures most of the ZBB benefit with manageable implementation effort.
How Zero-Based Budgeting Works in Hotels
Identify Activities → Define Resource Needs → Cost at Current Rates → Rank by Priority → Allocate Budget The ZBB process follows five sequential steps. First, each department identifies every discrete activity it performs (e.g. the marketing department lists paid search, social media management, email campaigns, print advertising, trade shows, photography updates, etc.). Second, each activity is broken down into the resources it requires, staff hours, external supplier costs, technology subscriptions, physical materials. Third, those resources are costed at current market rates, not rolled-forward historical figures. Fourth, activities are ranked by priority based on their contribution to revenue, guest satisfaction or operational compliance, creating a clear hierarchy from essential to discretionary. Fifth, budget is allocated from the top of the priority list downward until the available funding is exhausted, ensuring that the most impactful activities are always funded and the least impactful are the first to be cut if savings are needed.
Decision Packages
The core unit of ZBB is the “decision package”, a documented proposal for each activity or cost line that describes what the activity is, why it is necessary, what it costs, what the alternatives are (including not performing the activity at all) and what the expected outcome or return is. In a hotel context, the housekeeping department might prepare decision packages for: deep-cleaning programme (frequency, staffing, chemicals, expected guest satisfaction impact), linen replacement schedule (quantity, quality tier, supplier options, guest feedback data), minibar restocking service (labour cost, product cost, revenue generated, guest utilisation rate) and outsourced window cleaning (frequency, current contract cost, alternative quotes). Each package is evaluated independently, not as part of an inherited budget block. This granularity is what makes ZBB powerful, and what makes it time-consuming.
Priority Ranking and Trade-Offs
Once decision packages are prepared, management ranks them across departments to create a property-wide priority list. This ranking forces explicit trade-off decisions that incremental budgeting hides. Is a £15,000 investment in a new email marketing platform (expected to generate £42,000 in direct booking revenue) a higher priority than a £15,000 programme of lobby furniture refurbishment (expected to improve guest satisfaction scores and online review ratings)? In incremental budgeting, both would likely be funded if they were “in the base” or cut proportionally if savings were needed. In ZBB, they are evaluated against each other on the basis of ROI, strategic alignment and operational necessity, and the less impactful activity may not be funded, freeing resources for higher-return uses.
Rolling ZBB Reviews
Leading hotel operators do not apply full ZBB to every cost line every year, the administrative burden would be unsustainable. Instead, they implement a rolling programme in which different cost categories are subject to zero-base review on a two- or three-year cycle. Year one might apply ZBB rigour to marketing and sales costs; year two to maintenance and engineering; year three to administration and back-office functions. Meanwhile, categories not under zero-base review in a given year are budgeted incrementally but with tighter scrutiny informed by the ZBB discipline. This rolling approach maintains cost awareness across the organisation without creating budget fatigue.
Practical Example
In practice, this concept only creates measurable value when your hotel links it to clear operating routines, owner-level KPIs and a realistic implementation roadmap. Define one concrete use case, measure baseline performance, roll out in short cycles, and review results monthly with Revenue, Commercial, Operations and Tech in one steering rhythm.
In practice
A 210-room city-centre hotel in Manchester, operated under a management contract, has seen its GOP margin decline from 38% to 33% over three years despite stable RevPAR. The owning company requests a detailed cost review. Your hotel's total operating expenses are £4.2 million, and departmental budgets have been set incrementally for as long as anyone on the management team can recall.
The general manager and financial controller implement a zero-based budget process for the upcoming fiscal year, focusing on four high-impact cost categories. (1) Marketing spend (prior-year budget: £185,000): Every campaign, subscription, agency fee and advertising placement is documented as a decision package with expected ROI. The review reveals £28,000 in legacy costs, a print advertising commitment in a tourism guide that generates negligible trackable bookings (£9,500), a social media management tool licence duplicated across two departments (£4,200), an annual trade show attendance with no measurable lead generation (£8,800), and a photography retainer for quarterly shoots when the hotel's visual content needs have already been met (£5,500). (2) Maintenance and engineering (prior-year: £310,000): Decision packages reveal that three preventive maintenance contracts totalling £22,000 cover equipment replaced within the last 18 months, and that the reactive maintenance budget of £85,000 can be reduced to £65,000 by shifting to a structured preventive programme. (3) Administrative costs (prior-year: £195,000): The review identifies £14,000 in redundant software subscriptions and a £7,500 outsourced service whose function has been absorbed by a recent PMS upgrade. (4) Guest supplies (prior-year: £92,000): A full supplier retendering process triggered by ZBB analysis yields a 12% cost reduction on bathroom amenities through a new supplier at equivalent quality.
The zero-based budget process identifies £91,500 in eliminable costs and £11,000 in procurement savings, a total of £102,500 in annual savings against a £4.2 million cost base (2.4%). Of this, £45,000 is reinvested in high-ROI activities identified during the process: a direct booking campaign (£25,000 budget, projected to generate £95,000 in commission-saved revenue) and a guest experience enhancement programme (£20,000) targeting the hotel's weakest review categories. Net annual saving: £57,500. Your hotel's projected GOP margin recovers from 33% to 35.1%. The owning company mandates rolling ZBB reviews for all managed properties in the portfolio.
Relevance for hotel operations
Finance & Controlling
The finance team leads the ZBB process, designing the decision-package templates, training departmental managers, consolidating and ranking proposals, and modelling the impact of different funding scenarios on GOP and net income. ZBB transforms finance from a data-recording function into a strategic advisory role, positioning the financial controller as a key partner in resource allocation decisions.
Revenue Management
ZBB encourages revenue managers to think holistically about the cost of generating revenue, not just rate and occupancy targets. Distribution costs (OTA commissions, GDS fees, channel manager subscriptions), marketing spend per booking channel and technology investments must all be justified against the revenue they generate. This creates a natural synergy between revenue management and cost management.
Food & Beverage
F&B departments often carry the most legacy costs, supplier contracts that have not been retendered, menu items that persist despite poor margins, staffing rotas designed for historical covers rather than current demand. ZBB forces a rigorous review of food cost, beverage cost, labour scheduling and supplier terms against current revenue and profitability data.
Sales & Marketing
Marketing budgets are prime ZBB territory because they frequently contain subscriptions, agency retainers and campaign commitments that persist through inertia. Requiring each marketing activity to be justified from zero, with clear KPIs and expected ROI, redirects spending from comfortable habits to high-impact channels and ensures that the marketing mix reflects current market conditions.
General Management
For the general manager, ZBB provides visibility into cost structures that is impossible to achieve through incremental budgeting. The decision-package approach creates a property-wide priority map that supports informed trade-off decisions, demonstrates cost discipline to owners and asset managers, and builds a culture of accountability where every manager understands the business case for their expenditure.
Common mistakes & best practices
Common mistakes
- Applying ZBB to genuinely fixed costs: Subjecting contractually fixed obligations, lease payments, franchise fees, insurance premiums, property taxes, to a zero-base review wastes management time and creates frustration because these costs cannot be varied regardless of the analysis. ZBB should focus on discretionary and semi-variable costs where meaningful reallocation is possible. Fixed costs are better addressed through contract renegotiation on renewal or strategic benchmarking exercises, not through annual zero-base justification.
- Cutting without reinvesting: ZBB is not exclusively a cost-cutting tool, it is a resource-optimisation methodology. Hotels that use ZBB solely to reduce total expenditure, without reinvesting savings into higher-return activities, miss the strategic purpose of the approach. Eliminating £30,000 in low-value marketing spend is only half the benefit; redirecting that £30,000 into a direct booking strategy that reduces OTA dependency completes the value cycle.
- Conducting ZBB as a one-off exercise: Some hotels implement ZBB once during a cost crisis, achieve savings, and then revert to incremental budgeting, allowing costs to creep back over subsequent years. ZBB delivers sustained value only when embedded as a rolling discipline: different cost categories reviewed from zero on a structured cycle, with the rigour maintained across budget periods.
Best practices
- Start with the highest-impact cost categories: Rather than attempting a full zero-base review of every cost in year one, begin with the two or three categories that are largest, most discretionary and most likely to contain hidden inefficiencies. In most hotels, marketing, maintenance, supplies and outsourced services are productive starting points. Early wins build organisational confidence and demonstrate the methodology's value before expanding scope.
- Provide clear decision-package templates and training: Departmental managers are operational experts, not finance analysts. If the ZBB process requires them to complete complex financial documentation without guidance, the quality of submissions will be poor and resistance will be high. Provide simple, structured templates with worked examples and offer training sessions that explain the purpose, process and expected outcomes of ZBB.
- Link ZBB to strategic priorities, not just savings targets: Frame ZBB as a tool for ensuring resources are allocated to the activities that matter most, not as a mechanism for arbitrary budget cuts. When managers understand that ZBB may result in their department receiving more budget (redirected from lower-priority areas elsewhere), engagement shifts from defensive to constructive.

What you should know about this term.
Traditional incremental budgeting takes last year's actual spending as the starting point and applies a percentage increase or decrease, for example, "marketing spent £120,000 last year, so budget £126,000 this year (a 5% uplift)". This approach assumes that last year's spending was fundamentally correct and only the total needs adjusting. Zero-based budgeting starts from zero: every cost line must be justified anew based on current business needs, planned activities and expected returns. The marketing department would need to build its budget from scratch, specifying each campaign, channel, target audience and expected ROI, rather than inheriting last year's allocation. ZBB is more resource-intensive to prepare but far more effective at eliminating waste, identifying redundant costs and aligning spending with current strategic priorities rather than historical inertia.
Yes, but the implementation approach should be scaled appropriately. A small independent hotel does not need the full corporate ZBB framework used by large hotel groups with dedicated finance teams. Instead, the owner or general manager can apply ZBB principles selectively, choosing two or three cost areas each year for a zero-base review whilst budgeting other areas incrementally. Common starting points for small hotels include marketing spend (where legacy subscriptions and underperforming channels often persist unchallenged), supplier contracts (where annual renegotiation or retendering can yield significant savings), and maintenance budgets (where reactive spending patterns can be restructured into more cost-effective preventive programmes). The key benefit for small hotels is the same as for large groups: ensuring that every pound spent is delivering value against current business conditions, not simply repeating what was spent last year.
