Calculate Break-Even Point

Help me calculate the break-even point for my Shopify store:

Fixed Costs (Monthly):
List all costs that stay the same regardless of sales volume:

  Shopify plan subscription: [AMOUNT]
  App subscriptions total: [AMOUNT]
  Rent or workspace costs: [AMOUNT]
  Salaries and payroll: [AMOUNT]
  Insurance: [AMOUNT]
  Software tools and services: [AMOUNT]
  Loan or debt payments: [AMOUNT]
  Other fixed costs: [LIST WITH AMOUNTS]
  Total fixed costs: (calculated)


Variable Costs (Per Order):
List costs that change with each sale:

  Average product cost (COGS per unit): [AMOUNT]
  Payment processing fee per order: [PERCENTAGE + FLAT FEE]
  Shipping cost per order (average): [AMOUNT]
  Packaging materials per order: [AMOUNT]
  Marketplace or channel fees: [PERCENTAGE IF APPLICABLE]
  Returns and refunds allowance: [PERCENTAGE OF ORDERS]
  Other variable costs: [LIST WITH AMOUNTS]
  Total variable cost per order: (calculated)


Revenue Assumptions:

  Average selling price (ASP) or average order value: [AMOUNT]
  Average units per order: [NUMBER]
  Average discount rate applied: [PERCENTAGE]


Break-Even Calculations:

  Contribution margin per order = AOV - variable costs per order
  Break-even orders = total fixed costs / contribution margin per order
  Break-even revenue = break-even orders x AOV
  Break-even daily orders = monthly break-even / 30
  Current margin of safety (how far above or below break-even am I?)


Scenario Modeling:
Calculate break-even under different conditions:

  Scenario A: Price increase of [10]% with [5]% volume decrease
  Scenario B: COGS reduction of [15]% (new supplier or negotiation)
  Scenario C: Fixed cost increase of [AMOUNT] (hiring, new tool)
  Scenario D: Marketing spend increase of [AMOUNT] with [X]% revenue lift
  Scenario E: Custom scenario: [DESCRIBE YOUR SCENARIO]


Sensitivity Analysis:

  How does break-even change with each $1 increase in AOV?
  How does break-even change with each 1% reduction in COGS?
  At what discount level do I start losing money per order?
  Minimum viable order count to sustain current operations


Visual Output:

  Break-even chart showing costs, revenue, and intersection point
  Monthly P&L projection at break-even volume vs current volume
  Timeline: when will I reach break-even if growing at [GROWTH RATE]%?


Present all calculations clearly with formulas so I can update the numbers.
