I have it at the same as you, they require +4.56% to hit $1 trillion.
Edit - Longer answer:
We need a target of 1000B, and the current market cap according to Google is 956.4B, so to calculate the % increase needed, I did:
((1000 - 956.4) / 956.4) * 100 = 4.55876202426%
This assumes the market cap is right. If the market cap is wrong and the right market cap is 935B as mentioned below, then the % increase needed is:
((1000 - 935) / 935) * 100 = 6.95187165775%
