Track your own sell-through
Your multi-year sales history is more useful than an industry average because it reflects your portfolio quality and pricing.

Model the interaction between sell-through, sale prices, marketplace fees, renewals, drops, and continued buying—not just the value of one successful sale.
Sell-Through SensitivitySame portfolio, costs, and sale price
Cautious0.5% annual sell-through
-$16,536 net profit-$1,219 year-1 cash flow
1% BaselineOne expected sale per 100 domains
-$2,957 net profit$1,438 year-1 cash flow
ImprovedA 50% lift over the 1% baseline
$10,396 net profit$4,094 year-1 cash flow
What Looks Sustainable
- Expected first-year sales cover renewals and planned acquisitions
- The entered sell-through rate produces at least one expected annual sale
- Entered sell-through is above the first-year operating break-even rate
- The plan includes pruning rather than renewing every domain indefinitely
Points to Review
- The initial portfolio cost is not recovered within 5 years
- Renewal inflation compounds across the entire remaining portfolio
- The portfolio grows faster than domains leave it, increasing future renewal exposure
Cash-flow forecast
See the Portfolio Change Each Year
Sales reduce inventory, drops control renewal exposure, and new purchases add both future opportunity and future carrying cost.
| Year | Starting | Expected Sales | Dropped | Ending | Net Cash Flow | Cumulative |

| Year 2 | 252.7 | 2.5 | 20 | 255.2 | $1,311 | -$6,002 |

Portfolio discipline
What Moves Portfolio ROI
Sell-through measures the percentage of inventory sold each year. A one-point change can transform cash flow, but only if the average net sale proceeds reliably exceed renewals and continued acquisition spending.
Measure net proceeds
Gross sale prices can hide marketplace fees, acquisition cost, and years of renewals.
Prune deliberately
Keeping every domain forever can turn weak inventory into a compounding renewal liability.
Control acquisition pace
New purchases should be funded by a plan, not by assuming future sales will arrive on schedule.
