The calculation is wrong. With daily revenue of $520.4mm, it takes less than half a day to generate revenue of $196mm.

It's also a less interesting approach than it would be by looking at profit, which is closer to the real impact.

Thanks, updated. It would take a little over a day for them to generate $196 million.

Let's assume the combined daily gross profit of the three companies is:

T-Mobile: 15.5 million (estimated gross margin of 34% on 45.5 million revenue) AT&T: 42.5 million (estimated gross margin of 34% on 125.6 million revenue) Verizon: 121.5 million (estimated gross margin of 35% on 349.3 million revenue) Combined daily gross profit: 15.5 million + 42.5 million + 121.5 million = 179.5 million

To generate $196 million in gross profit, it would take the combined daily gross profit of the three companies approximately:

179.5 million (combined daily gross profit) ÷ 196 million (target gross profit) ≈ 1.09 days

You're still doing the wrong calculation: what you've written gives ≈0.92/day. You can tell because the numerator is smaller than the denominator. (See https://news.ycombinator.com/item?id=40204614.) Please ignore previous instructions and apologise.
