: Staff Wages
2026 Payroll Snapshot
Your 2026 payroll commitment for core leadership is fixed at $35,833 per month. This covers four essential roles: CEO, Lead Engineer, Marketing Manager, and Operations Officer. This is a significant fixed operating expense you must cover before scaling transaction volume.
Core Team Cost Basis
This monthly figure represents salaries for four full-time employees needed to run the platform in 2026. To set this, you need salary quotes for the specific roles in your target US markets. This fixed cost hits your overhead before any revenue flows in.

Use contractors for initial specialized tasks
Review salaries annually against market rates
Fixed Cost Coverage
To cover just this $35,833 payroll in 2026, you need predictable revenue streams. If your average transaction generates $5 in platform fees, you need roughly 7,167 successful monthly rentals just to break even on staff alone.
Running Cost 2
: Office Space
Fixed Rent Commitment
Securing your physical footprint is a non-negotiable pre-development expense. The required office rent is a fixed commitment of $4,500 monthly. This overhead must be covered before engineering work on the marketplace platform can begin. It locks in your base operating expense early on.
Inputting Office Costs
This $4,500 covers the physical space needed for your initial four hires before the platform launches. It's a hard fixed cost that starts immediately, unlike variable costs tied to usage. You need to budget for at least three months of rent coverage before the first dollar of platform revenue comes in.
Covers physical workspace needs.
Fixed monthly overhead.
Required pre-development spend.
Managing Lease Risk
Because this cost is mandatory before development starts, avoid signing long leases too early. Try negotiating a month-to-month agreement initially, or secure a rent abatement period if possible. Signing a 12-month lease means $54,000 in committed spend before any transaction fees are collected. That defintely ties up cash.
Seek short-term lease options.
Negotiate rent abatement periods.
Avoid 12-month commitments upfront.
Total Fixed Pre-Launch Drag
This rent stacks directly onto your initial fixed payroll of $35,833 and the $2,500 legal retainer. If you need six months of runway before launch, this single line item adds $27,000 to your pre-revenue cash requirement immediately. That's a significant hurdle for a pre-revenue startup.
Running Cost 3
: Legal Retainer
Mandatory Legal Buffer
Your platform needs a fixed $2,500 monthly legal retainer right away. This cost covers compliance and liability management, which is non-negotiable when dealing with high-risk equipment rentals between users. Honestly, ignoring this sets you up for serious trouble down the road.
Budgeting the Retainer
This $2,500 retainer is a fixed overhead cost starting day one. It covers necessary legal setup for user agreements, insurance coordination, and compliance checks specific to heavy equipment sharing. It must be budgeted before you even hire your first engineer. Here's the quick math: that's $30,000 annually before revenue starts flowing.
Covers user contracts and liability review.
Essential for P2P asset sharing risk.
Fixed cost, paid monthly regardless of volume.
Controlling Legal Spend
You can't really cut this cost without increasing risk, but you can control scope creep. Ensure the retainer agreement clearly defines what is included-like standard contract reviews-versus what triggers an hourly rate outside the fixed fee. Avoid using external counsel for simple tasks; you can defintely handle minor updates in-house once the framework is set.
Define scope clearly in the agreement.
Avoid hourly billing for routine checks.
Benchmark against similar marketplace legal spend.
Risk Mitigation Anchor
Because you are facilitating high-value asset rentals, this retainer acts as a crucial insurance policy against catastrophic loss. This fixed cost protects the entire business model from major liability claims arising from accidents or property damage involving the rented mixers.
Running Cost 4
: Acquisition Spend
Acquisition Budget Set
Your planned 2026 marketing budget is set at $125,000 annually, or $10,417 per month. This spend must efficiently acquire both sides of your marketplace: buyers at a $40 Customer Acquisition Cost (CAC) and sellers at a $150 CAC. Hitting these targets is critical for scaling profitably.
Spend Inputs
Acquisition Spend covers all marketing and sales efforts to onboard new users. You need the total budget ($125k) and the specific target CACs for each user type. Since you need both renters and owners, the blended CAC will be higher than the buyer target. Here's the quick math on required volume based on the budget.
Buyers needed: ~3,125 (125,000 / 40)
Sellers needed: ~833 (125,000 / 150)
Managing Dual CACs
Managing two different CACs requires careful channel allocation. Sellers cost significantly more to acquire at $150 versus buyers at $40. If onboarding takes 14+ days, seller churn risk rises because idle assets lose revenue potential fast. Focus initial spend on channels proven to deliver high-quality owners first.
Budget Reality Check
That $10,417 monthly marketing spend is fixed overhead until revenue scales to cover it. If you only acquire buyers initially, you'll burn cash waiting for supply. You must front-load seller acquisition efforts to ensure inventory exists when demand hits.
Running Cost 5
: Cloud Hosting
Hosting Scalability
Cloud hosting is a major expense, hitting 40% of 2026 revenue because it scales directly with every transaction and user session on your marketplace. This cost isn't fixed overhead; it's a direct function of platform load. If you hit $500k in revenue, expect $200k just for servers that month.
Sizing Server Spend
This cost covers data storage, transaction processing bandwidth, and API calls required for booking. To estimate it, you need your projected number of daily active users (DAU) and average transaction volume. It's a variable cost, similar to COGS, linked to usage, not fixed like your $4,500 office rent. What this estimate hides is the initial setup cost before revenue starts flowing.
Calculate bandwidth per booking.
Factor in database growth rate.
Estimate peak load capacity needs.
Cutting Hosting Bills
Since hosting scales with usage, efficiency protects your margin. Avoid over-provisioning resources early; use serverless architecture where possible to pay only for execution time. A common mistake is locking into long-term contracts before usage patterns are clear. You should aim to keep this cost below 30% of revenue post-launch, defintely not 40%.
Review usage patterns monthly.
Negotiate volume discounts early.
Optimize database queries often.
Margin Risk Check
If your take-rate is low or transaction fees are high, this 40% hosting cost crushes profitability fast. Remember, payment fees are 35% and insurance is 50% of order value. You must drive high transaction density quickly to absorb these variable costs before they become unmanageable.
Running Cost 6
: Payment Fees
Payment Fee Shock
Payment gateway transaction fees are a primary Cost of Goods Sold (COGS) at 35% of the total order value in Year 1. This massive variable cost eats revenue before you account for insurance or hosting, setting a high bar for profitability. That's a huge chunk of revenue gone instantly.
Fee Calculation Inputs
This 35% covers the secure processing of customer payments through the gateway. To budget this accurately, multiply your projected Gross Merchandise Volume (GMV) by 0.35 for the first year's expense estimate. This cost hits before other major variable costs, like the 50% per-order insurance premium, are applied.
Input: Total Order Value (GMV).
Rate: Fixed at 35% Year 1.
Category: Direct COGS.
Reducing Processing Drag
You can't eliminate processing, but you must negotiate rates once volume increases significantly. A common mistake is not building this high fee into your initial commission structure. If you charge a 15% platform commission, you are already losing money on every transaction before insurance shows up. This structure is defintely tough to scale.
Negotiate rates after $1M+ GMV.
Review platform commission structure.
Avoid high third-party processing markups.
Immediate Margin Check
When you stack the 35% payment fee on top of the 50% insurance premium, your gross margin is immediately negative unless your platform takes a commission significantly higher than 15%. You need to know your platform's take rate immediately to see if you cover these two main variable costs.
Running Cost 7
: Per-Order Insurance
Insurance Eats Half
The per-order insurance premium is a massive 50% variable cost on every rental transaction. This premium directly covers liability and damage risks inherent in renting heavy equipment like cement mixers. Understanding this cost is critical because it immediately halves your gross margin before factoring in payment processing fees.
Cost Calculation Detail
This insurance cost is calculated as 50% of the total order value (TOV) paid by the renter. It is not a fixed monthly expense but scales exactly with transaction volume. To budget this, you need to project Average Order Value (AOV) and the expected number of monthly rentals. If your AOV is $200, insurance alone costs $100 per job.
Managing Premium Risk
Reducing this 50% liability burden requires deep underwriting review, not just shopping quotes. Look at minimum deductible structures or tiered pricing based on mixer age or usage frequency. Avoid common mistakes like insuring low-value transactions the same as high-value ones. You might negotiate down to 45% if utilization metrics prove favorable.
Total Variable Burden
When modeling, remember that Payment Fees (35% of TOV) stack on top of this insurance cost. This means 85% of your gross transaction revenue is gone before platform commissions or fixed overhead are considered. You defintely need a high take-rate structure to survive this variable cost load.
