Running Cost 7
: Variable Sales Costs
Variable Cost Shock
Your cost structure is heavily weighted toward direct sales expenses. Variable costs, driven by commissions and logistics, consume a massive portion of top-line revenue. In 2026, these costs are projected to eat up 90% of your total sales dollars. That leaves very little margin before covering fixed overhead.
Cost Calculation
These costs tie directly to every dollar earned from fabricating large metal parts for aerospace and defense. Sales Commissions are set at 30% of the sale price. Shipping, which covers specialized logistics for massive components, adds another 20%. This means for every $100 in revenue, $50 is immediately gone to sales and delivery costs.
Commissions equal 30% of revenue.
Shipping costs are budgeted at 20%.
Total known variable costs are 50%.
Managing Sales Spend
Since commissions and shipping are high, managing the sales cycle efficiency is paramount. Focus on securing larger, multi-year contracts with key primes to reduce the frequency of high-commission transactions. Also, investigate direct freight contracts rather than relying solely on third-party logistics providers to chip away at that 20% shipping line item. Defintely look at sales incentives tied to margin, not just gross revenue.
Target larger, fewer transactions.
Negotiate direct freight rates.
Incentivize margin over volume.
Margin Pressure Point
The 90% total variable sales cost projection for 2026 means your gross margin is razor thin before fixed costs hit. If your actual sales commissions run higher than 30% due to aggressive early hiring, or if component shipping becomes more complex, you will quickly fall below the break-even point established by your $25,000 lease and $68,333 monthly payroll.
