i.lease ROI Calculator
Quantitatively compare the one-time proceeds from selling your IPv4 block with the cumulative income generated through leasing over time. This calculator helps you evaluate cash outcomes under different assumptions without prescribing a decision.

Compare Selling vs. Leasing IPv4 Assets
Use the table to compare how each option is realized over time — one-time proceeds vs. cumulative lease income.
How the ROI Calculator Works
Input Assumptions
You provide basic parameters including IP block size, estimated sale price per IP, Monthly lease rate per IP, Evaluation period (months or years).
Revenue Modeling
The calculator calculates one-time proceeds for selling, aggregates recurring lease income over time, and aligns both metrics to the same horizon for comparison.
Output Comparison
Results are displayed as total cash received (Sell vs Lease), cumulative income over time, break-even point, if applicable.
Data & Assumptions Transparency
See where the inputs come from and what assumptions power the calculation. This helps you interpret the results with confidence.
Sale prices are based on recent market transactions
We use recently observed IPv4 sale benchmarks to estimate a realistic one-time sale value for your block.
Lease rates reflect current market ranges
Lease income is calculated using prevailing lease-rate ranges across major regions, giving you a reasonable baseline for monthly revenue.
Results assume continuous leasing over the selected period
The model assumes the block remains leased throughout the time horizon so cumulative income can be compared consistently against a one-time sale.
