I live right by LaGuardia, and every time I've taken a taxi home from the Times Square area, it's been $20 with tip.
From JFK, to reiterate what someone already said, if you don't have much baggage take the AirTrain to the blue line and take that to Port Authority. It'll be less than $10.
Edit to add:
From LaGuardia, if you don't have much luggage, take the M60 bus to the Astoria Blvd. Stop on the N/W yellow line, and take that to Times Square. That will cost less than $5.
"If this is going to be a Christian nation that doesn't help the poor, either we have to pretend that Jesus was just as selfish as we are, or we've got to acknowledge that He commanded us to love the poor and serve the needy without condition and then admit that we just don't want to do it." -Stephen Colbert
