Running Cost 1
: Wages and Salaries
Payroll Baseline
Payroll starts at $11,875 monthly in 2026, making it your primary fixed cost driver. This commitment covers 15 FTEs, including the Lead Consultant and Administrative Assistant positions you plan to staff. You must secure revenue quickly to cover this base.
Cost Breakdown
This $11,875 monthly expense in 2026 is the budgeted salary and overhead for 15 FTEs. To estimate this, you need the fully loaded cost per employee, including benefits and payroll taxes, for roles like the Lead Consultant. This cost is fixed overhead, independent of service revenue.
Baseline monthly payroll: $11,875
Staff count: 15 FTEs
Key roles: Lead Consultant, Admin Assistant
Managing Labor Costs
Since labor is the main cost, focus on high utilization rates for all 15 staff members. Avoid hiring ahead of demand; every unfilled role burns cash against that $11,875 fixed commitment. Use fractional arrangements until client volume justifies full-time hires.
Delay hiring until utilization hits 80%.
Negotiate salary bands carefully now.
Track billable hours vs. total hours closely.
The Breakeven Hurdle
Your revenue must generate enough gross profit to cover $11,875 in payroll plus the $18,000 in other fixed costs ($2,500 rent + $1,250 marketing + $250 software) before you see profit. This high fixed burden means you need steady client intake, defintely starting in 2026.
Running Cost 2
: Office Rent
Rent Starts 2026
Office rent hits as a fixed $2,500 per month starting January 2026. This predictable cost immediately adds to your fixed overhead, making early revenue generation absolutely critical to cover it before it starts impacting cash flow.
Fixed Overhead Hit
This $2,500 covers your physical workspace, kicking in January 2026. It's a non-negotiable fixed cost, unlike variable software fees (which start at 30% of revenue). You must budget for this $30,000 annual commitment regardless of how many clients you land early on.
It sits on top of $11,875 in baseline monthly wages.
Requires detailed lease negotiation now.
Lease Strategy
Negotiate the lease start date carefully; pushing the January 2026 occupancy avoids paying rent while you are still building capacity. Aim for shorter initial terms, maybe three years, to limit exposure if your location needs change fast. Don't sign until sales pipelines look solid, honestly.
Push rent commencement date back.
Avoid long-term commitments initially.
Look for tenant improvement allowances.
Break-Even Impact
That $2,500 rent is pure fixed overhead. Since variable costs like travel (40%), software (30%), and compliance (20%) eat up 90% of revenue, your effective contribution margin is only 10%. You need $25,000 in monthly revenue just to service the rent component.
Running Cost 3
: Client Acquisition Marketing
Marketing Spend Target
Client acquisition marketing is budgeted at $15,000 for 2026, demanding a $1,800 Customer Acquisition Cost (CAC) to be effective. Hitting this goal means securing about 8 new consulting clients annually from marketing spend alone.
Inputs for Client Volume
This $15,000 annual spend breaks down to $1,250 monthly. To justify this, you must acquire 8.33 new clients per year, or roughly 0.7 clients monthly, defintely assuming the $1,800 CAC holds. This covers all initial outreach expenses.
Annual spend: $15,000
Target CAC: $1,800
Implied new clients: 8.33
Managing CAC Risk
Managing this cost means focusing intensely on lead quality, not just volume. Since the budget is fixed at $1,250 monthly, any CAC over $1,800 directly cuts your potential client count. You need efficient sales processes to close leads quickly.
Track lead-to-client conversion rates.
Test channels before scaling spend.
Ensure sales collateral is sharp.
Pipeline Timing Check
If your first client takes six months to land due to long consulting sales cycles, you’ve spent $7,500 before seeing any revenue from that acquisition. That means the $1,800 CAC target relies on quick conversion from initial contact.
Running Cost 4
: Fixed Software Subscriptions
Essential Software Spend
You need dedicated systems for client management and project tracking right away. The fixed software cost for your CRM and Project Management tools is set at $250 monthly. This baseline spend supports operational efficiency and ensures client data integrity from day one.
Cost Inputs
These $250 monthly payments cover your core technology stack needed to manage client pipelines and ongoing consulting engagements. This is a fixed overhead cost, unlike variable expenses like travel or specialized licenses. You budget this amount for 12 months regardless of revenue volume.
CRM for pipeline tracking.
PM tools for service delivery.
Fixed at $250/month total.
Optimization Tactics
Avoid over-buying features you won't use immediately. Start with lower-tier plans; scaling up later is cheaper than paying for unused capacity now. A common mistake is paying for enterprise features when a small business tier suffices. You can defintely save money by bundling services if the provider allows.
Tracking ROI
Since this is a fixed cost, you must track its return on investment (ROI) against billable hours. If your CRM usage doesn't directly lead to closing deals or managing projects efficiently, that $250 is just overhead eating into your margin. Measure utilization monthly.
Running Cost 5
: Specialized HR Software Licenses
Software Cost Hit
Specialized HR software licenses are a 30% variable cost against revenue starting in 2026. These tools are not optional; they power the specific compliance checks and client reports you promise. If revenue hits $100k, expect $30,000 immediately allocated here.
Estimate Inputs
This 30% of revenue covers essential, industry-specific tools needed for service delivery, like compliance monitoring software or advanced talent analytics platforms. To budget accurately, map required tools to your service packages. If a standard client engagement requires $150 in per-user licensing fees monthly, you must track licenses against active client counts to defintely project this expense correctly.
Map licenses to service tiers.
Track usage per client.
Factor in annual renewal spikes.
Manage Licenses
Since these tools ensure compliance, cutting them risks regulatory fines. Instead, focus on vendor negotiation and utilization rates. Avoid paying for full seats if you only use 75% of the functionality. Can you bundle smaller tools into a single platform subscription for a 10% discount?
Audit unused seats monthly.
Seek annual contract savings.
Standardize tools across consultants.
Compliance Risk
Failing to budget for these specialized licenses means you cannot legally or effectively deliver promised HR consulting services. Under-resourcing this cost directly translates to increased liability for your clients and, ultimately, for your firm.
Running Cost 6
: External Compliance Fees
Compliance Cost Hit
Because HR consulting is so regulated, external compliance audit fees will eat up 20% of your 2026 revenue. This cost is fixed as a percentage, meaning revenue growth doesn't reduce its proportional impact on your gross margin.
Audit Cost Drivers
These fees cover mandatory external reviews ensuring client policies meet federal and state labor laws. To estimate this cost, you need projected 2026 revenue, as the input is simply Revenue times 20%. This variable expense sits alongside software licenses (30%) and travel (40%) as a major revenue drag.
Input: Projected 2026 Revenue
Output: 20% of that total
Benchmark: High due to regulation
Controlling Audit Spend
You can't eliminate required compliance checks, but you can control the scope and efficiency of the review. Standardize your client deliverables to use fewer audit hours. If you onboard clients using a strict, pre-vetted template, you defintely reduce the complexity auditors must review.
Standardize policy templates
Require clean client data upfront
Negotiate fixed audit retainers
Margin Pressure Point
Compliance fees (20%), software licenses (30%), and travel (40%) immediately consume 90% of revenue before you pay a single employee. This leaves only 10% contribution margin to cover fixed costs like the $11,875 monthly payroll.
Running Cost 7
: Client Travel and Expenses
T&E Drives Top Line
Client Travel and Expenses (T&E) will consume 40% of total revenue in 2026, making it the largest single expense category by far. Since these are direct, reimbursable site visit costs, they inflate the gross revenue figure without necessarily reflecting true operational profitability. You must track these pass-through costs meticulously against client billing.
Estimating Travel Spend
This cost covers necessary site visits for policy implementation and employee relations work. To estimate this accurately, you need the number of required client site visits multiplied by the average cost per trip (flights, lodging, per diem). Given T&E is 40% of revenue, if you project $500k in 2026 revenue, expect $200k in travel costs. What this estimate hides is the actual margin impact if travel isn't billed at 100% markup.
Controlling Reimbursables
Since this is a direct pass-through, the focus isn't cutting the cost, but ensuring proper client invoicing and avoiding scope creep that generates unnecessary travel. A common mistake is absorbing minor travel fees into the hourly rate instead of itemizing them. Keep all receipts tied directly to project codes. If onboarding takes 14+ days, churn risk rises due to delayed site visits.
Bill travel costs at 105% markup.
Use remote audits first.
Define travel boundaries upfront.
Margin Risk Check
While T&E is technically reimbursable, its size relative to other costs—like variable software at 30%—means cash flow timing is critical. If clients delay payment on large project invoices that include travel reimbursements, your working capital gets squeezed fast. You defintely need strong accounts receivable controls here.
Total monthly fixed costs (rent, software, admin) are $4,280, plus payroll starting at $11,875 Total baseline running costs exceed $16,155 monthly before variable client expenses (which are 12% of revenue in 2026)
Breakeven is projected for August 2028, requiring 32 months This long runway is typical for service firms scaling high-salary staff and requires a significant capital buffer
Wages are the largest expense, starting at $142,500 annually in 2026 This cost scales rapidly, increasing FTEs from 15 in 2026 to 70 by 2030, driving the need for continuous client acquisition
The financial model shows a minimum cash requirement of $546,000, needed by August 2028 to cover cumulative operating losses
The projected CAC in 2026 is $1,800, based on an annual marketing budget of $15,000
Total variable costs (COGS and OpEx) start at 120% of revenue in 2026, decreasing slightly to 92% by 2030 due to scale efficiencies
