Running Cost 1
: Wages and Payroll
2026 Payroll Baseline
Your planned 2026 payroll hits $11,250 monthly. This budget accounts for the Founder’s salary plus one part-time Marketing Manager, officially pegged at 15 FTE (Full-Time Equivalents) for modeling purposes. This fixed cost needs to be covered before you see profit.
Payroll Inputs
This $11,250 monthly payroll is a fixed operating expense in 2026. To estimate this, you need agreed-upon salaries for the Founder and the part-time manager, plus employer burden rates (taxes, benefits). This cost sits outside COGS and must be covered by gross margin dollars generated from accessory sales. Honestly, check those burden rates.
Founder salary agreement defined.
Part-time manager wage rate set.
Employer tax burden percentage known.
Payroll Control
Managing payroll means strictly defining roles to avoid scope creep, especially for the Founder. Keep the Marketing Manager part-time until revenue clearly supports a full-time hire. If you hire too early, this fixed cost pressures your break-even point defintely. Don’t pay for capacity you don’t use.
Delay non-essential hiring.
Use contractors initially.
Track hours closely.
FTE Definition
Understand that the 15 FTE figure is your model’s assumption for this staff level; ensure your actual salary structure aligns with this total cost, or your fixed overhead will be higher. This number is critical for calculating overhead coverage ratios against your gross profit.
Running Cost 2
: Online Marketing Spend
Marketing Budget Setup
Your initial marketing plan sets aside $4,167 monthly for online acquisition in 2026. This budget targets a $25 Customer Acquisition Cost (CAC) in the first year of operation. Hitting this CAC is crucial for validating the unit economics of acquiring new customers for your curated accessory sales.
Acquisition Cost Math
This $50,000 annual spend covers all digital advertising necessary to attract new customers for your mobile accessories business. To achieve the target $25 CAC, you need to acquire 2,000 new customers ($50,000 / $25) over the year. If you aim for 12 months of spend, that means roughly 167 new customers per month to keep the budget on track.
Annual budget: $50,000
Target CAC: $25
Monthly customer target: ~167
Managing Acquisition Spend
Controlling CAC means optimizing conversion rates and increasing Average Order Value (AOV). If your AOV is low, a $25 CAC might be unsustainable, even if you hit the target. Focus on retargeting existing site visitors first; they are defintely cheaper to convert than cold traffic.
Test ad creative constantly.
Improve landing page conversion.
Increase Average Order Value (AOV).
CAC vs. LTV Check
You must calculate the expected Lifetime Value (LTV) of a customer immediately. If the average customer only spends $75 once, a $25 CAC leaves little margin after accounting for COGS (67%) and fulfillment (35% of revenue). A high repeat purchase rate is essential to justify this initial marketing outlay.
Running Cost 3
: Cost of Goods Sold (COGS)
Product Cost Reality
Your product costs are high, hitting 67% of revenue in 2026, based on the sales mix. This figure includes the wholesale price paid for all inventory—cases, protectors, chargers, and audio gear. Managing this percentage directly dictates your gross margin potential before overhead hits.
What COGS Covers
COGS covers the direct costs to acquire the inventory you sell. For mobile accessories, this means the wholesale price paid for cases (at 75% cost) and audio gear (at 55% cost). You need accurate unit costs and the projected sales mix to confirm that 67% blended rate.
Wholesale purchase price of units.
Inbound freight costs, if applicable.
Inventory holding costs, if tracked here.
Margin Levers
Reducing COGS means negotiating better supplier terms or shifting the sales mix. Since cases cost 75% versus audio at 55%, selling more lower-cost items improves margins fast. Be defintely careful not to sacrifice quality for a few percentage points, as that risks customer churn.
Negotiate volume discounts with suppliers.
Prioritize marketing for higher-margin items.
Audit landed cost monthly.
Gross Profit Pressure
When calculating gross profit, remember that high COGS compounds the impact of other variable costs like 35% fulfillment and 30% payment processing fees. If COGS creeps up to 70%, your remaining margin shrinks dramatically to cover fixed overhead costs like $1,200 in platform fees.
Running Cost 4
: Fulfillment and Shipping
Shipping Cost Drag
Fulfillment and shipping fees are a major variable outflow for your mobile accessories business. In 2026, these costs are projected to take 35% of total revenue. This means every new order brings a significant, fixed percentage cost that must be covered immediately.
Shipping Cost Inputs
This 35% figure covers all costs related to getting the product to the customer, including warehousing labor, packaging materials, and carrier postage. To estimate the actual dollar spend, you multiply projected 2026 revenue by 0.35. For example, if revenue hits $1.5 million, shipping is $525,000. This cost scales directly with order volume.
Reducing Fulfillment Fees
Reducing this cost requires aggressive management of carrier rates and packaging dimensions. Negotiate volume discounts with carriers like UPS or FedEx once you cross 5,000 shipments per month. Also, audit your packaging choices; using oversized boxes drives dimensional weight surcharges up fast. Defintely review your Cost of Goods Sold (COGS) to see if bundling items reduces the total number of shipments.
Margin Pressure Point
Because shipping is a direct percentage of revenue, it acts as a hard cap on your gross margin percentage. If your COGS is 67% and shipping is 35%, your blended margin before marketing is negative 2% unless your average selling price (ASP) is high enough to absorb both.
Running Cost 5
: E-commerce Platform Fees
Fixed Software Stack
Your core technology infrastructure costs $1,200 monthly, which is a fixed overhead for GearUp Mobile. This covers the main e-commerce platform at $800 and customer relationship management (CRM) tools at $400. This spend is essential before you sell a single unit.
Software Cost Breakdown
This $1,200 is your baseline technology commitment for 2026. It’s non-negotiable monthly overhead, unlike variable costs like Cost of Goods Sold (COGS) at 67% of revenue or fulfillment fees at 35% of revenue. You must budget for 12 months of coverage, totaling $14,400 annually.
Platform cost: $800/month.
CRM/Email cost: $400/month.
Fixed cost base.
Managing Tech Spend
Don't overbuy features early on; many founders waste money on enterprise tiers. If you start small, you might negotiate a lower introductory rate for the CRM or use a free-tier platform defintely initially. Watch out for hidden per-user fees in the CRM.
Audit unused seats now.
Avoid annual commitments early.
Check platform scalability costs.
Break-Even Impact
Since this $1,200 is fixed, every dollar of revenue above variable costs must cover it before you see profit. If your average contribution margin is, say, 30% (after COGS, fulfillment, and payment processing fees of 30%), you need about $4,000 in monthly gross sales just to cover this software stack.
Running Cost 6
: Payment Processing Fees
Processing Fees Hit Hard
Payment processing fees are a major variable hit for your e-commerce business, clocking in at 30% of gross revenue in 2026. This cost scales directly with every sale you make, meaning controlling your sales volume and transaction size directly impacts this expense line item. It's a necessary evil of taking plastic.
Estimating Processing Costs
This 30% covers the interchange, assessments, and markup charged by banks and processors for handling credit card transactions. To estimate this cost accurately, you need projected gross revenue multiplied by the 30% rate for 2026. This is a pure variable cost, unlike your fixed $1,200 monthly platform fees.
Use projected 2026 revenue.
Multiply revenue by 0.30.
Track per-transaction fees closely.
Managing Fee Exposure
Honestly, reducing this 30% rate requires negotiation or changing payment methods. Since you sell physical goods, card payments are unavoidable. Focus on driving higher Average Order Value (AOV) to dilute the impact of fixed per-transaction fees, or explore alternative payment methods if they have lower effective rates.
Negotiate processor rates annually.
Push customers toward ACH payments.
Increase average transaction size.
Variable Cost Pressure
When you look at your variable costs—COGS at 67%, fulfillment at 35%, and processing at 30%—you see the real pressure point. Your total direct costs exceed 100% of revenue if you don't manage margins well. This 30% fee is non-negotiable unless you change how customers pay you, so watch your blended rate defintely.
Running Cost 7
: Administrative Overhead
Fixed Overhead Snapshot
Your general fixed overhead sits at $1,300 monthly, which is relatively light for an e-commerce operation. This covers the bare minimum required to legally operate and stay connected, meaning it must be covered before you spend a dime on customer acquisition or inventory.
Cost Breakdown Inputs
This $1,300 is your baseline operating cost before sales begin. The largest piece is $600 for legal and accounting, which you estimate based on quotes for state registration and basic quarterly tax filing support. Utilities and internet are a fixed $200, while general administration is $500.
Admin budget: $500/month
Legal/Accounting: $600/month
Utilities/Internet: $200/month
Managing Fixed Needs
Since these costs are fixed, you can't reduce them easily once set, but you control the initial setup. Use standardized, template-based legal services for initial setup rather than custom law firm retainers. For accounting, use automated tools for bookkeeping, saving defintely over hiring a full-time bookkeeper now.
Bundle internet and phone services.
Delay hiring dedicated admin staff.
Use virtual mail services instead of office space.
Overhead Coverage Target
This $1,300 must be covered by your gross profit dollars every month. If your combined COGS and fulfillment fees eat up 80% of revenue, your gross profit margin is 20%. So, you need $6,500 in monthly revenue just to cover this fixed overhead before paying marketing or wages.
