Data Centers Pay for Themselves in 15 Months — Kim Deok-jin (IT Communication Research Institute)

An independent exercise, not a statement by the video creator or verification of every claim in the video.

Revenue-Based Ratios Versus Cash-Based Payback

In an independent hypothetical example, initial investment is 100, monthly revenue is 10, cash operating costs are 6 and additional maintenance investment is 1. Dividing investment by revenue gives 10 months, but cash available for recovery is 3 per month, implying simple payback of about 33.3 months. In a separate alternative, weaker demand reduces revenue alone to 8 while both expenditures stay unchanged; cash becomes 1 and payback extends to 100 months. Earlier operation can bring the start of inflows forward without making revenue equivalent to profit or ensuring all contracted maximum capacity is sold. Compare deployment time and changes in demand, pricing and costs separately using consistent cash-flow assumptions.

Check for yourself

1. Is the projected income contracted cash inflow or revenue estimated at maximum utilization?
2. Does the calculation include electricity, operations, replacement investment and financing costs?
3. Which inputs change if customer demand or power supply remains inadequate despite earlier operation?

Limits of application

This independent calculation does not estimate returns for an actual NVIDIA product or a particular data center. It assumes constant monthly cash flow and omits tax, interest, residual value, discounting and utilization ramp-up. Its purpose is to distinguish the inputs needed to test the title’s payback claim.
