Break-even MER is not a fixed number — it depends entirely on revenue level. At $350K/mo gross, max break-even MER is 10.8%. At $400K/mo, it's 16.2%. At $500K/mo, it opens to 23.8%. The 15% target Dan referenced requires roughly $390K/month gross revenue to be sustainable. In 2025, only 5 of 12 months exceeded $350K gross.
November is the clear efficiency winner: 17-21% MER with the highest absolute revenue ($479K-$604K). Spring launch months (Apr-May) generate strong revenue at 27-29% MER. June and Sept-Oct are the worst: high MER (30-35%) with middling revenue. The tactical play is to push MER higher during proven high-conversion windows and pull back hard during low-efficiency months.
The P&L has ~$151K/month in fixed costs (office labor $53K, warehouse labor $54K, rents $15K, software $5K, consultants $10K, interest + other $14K). Variable costs (raw materials + shipping) run ~35.5% of net revenue. This means every dollar of gross revenue generates $0.54 of contribution after variable costs. You need $280K/month gross just to cover fixed costs with zero marketing. The implication: cutting marketing to "save money" can actually make losses worse by pushing revenue below the fixed cost coverage threshold.
This table shows the maximum sustainable MER (ad spend as % of gross revenue) at different monthly gross revenue levels, given the current fixed cost base of ~$151K/month and variable costs at 35.5% of net revenue.

| $350K | $189K | $151K | $38K | 10.8% | Tight but workable |
| $400K (target) | $216K | $151K | $65K | 16.2% | Healthy break-even |
| $450K | $243K | $151K | $92K | 20.4% | Room for growth spend |

| $600K | $324K | $151K | $173K | 28.8% | Peak months (Nov) |
Plotting each month's actual gross revenue and MER against the break-even line shows how often the business was above vs below water.
Green dots = month where ad spend was below break-even max (contributing to profit). Red dots = month where ad spend exceeded break-even max (contributing to loss). The break-even curve is the blue line.

Understanding fixed vs variable costs is essential for setting the right MER target. Fixed costs set the floor — the business must generate enough revenue to cover them regardless of marketing spend.

Not all months are created equal. Some months naturally convert better, making higher MER worthwhile. Others are efficiency traps where spend generates diminishing returns.

Plotting all 27 months of data shows the relationship between spend level and revenue efficiency. Higher spend months generate more total revenue but at lower per-dollar efficiency. The question is whether the incremental revenue covers the incremental cost.
| Spend Quartile | Avg Monthly Spend | Avg Monthly Gross | Avg MER | Revenue per $1 Spend |
|---|---|---|---|---|
| Q1 — Lowest spend | $38,596 | $179,557 | 21.5% | $4.65 |
| Q2 | $58,810 | $258,291 | 22.8% | $4.39 |
| Q3 | $86,798 | $335,601 | 25.9% | $3.87 |
| Q4 — Highest spend | $107,024 | $374,373 | 28.6% | $3.50 |
Based on 2024-2025 seasonal patterns, here's a month-by-month MER target framework. These are ceilings, not floors — spend up to these levels if creative performance supports it.
Targets assume a $350K-$450K/month gross revenue goal. Adjust proportionally for actual revenue trajectory. The "push" months (green bars) are where incrementally higher spend has historically generated the best marginal returns.
| Month | Gross Revenue | Net Revenue | Net/Gross | Days | Daily Net Rev | vs Prior Year |

Net Revenue = Gross - Discounts - Returns - Platform Fees. Daily Net Revenue = Net Revenue / calendar days in month. 2026 months highlighted. March 2026 is partial (through Mar 23).
