Deductions & credits

[Married filing jointly] I have a w-2 for $110k and my wife has a w-2 for $6500 from our s-corp. I've entered around $7k in expenses for my 4 year old dependent and another $7k for my 3 year old dependent.  However, the Dependent Care Credit is being calculated out to $3,125... shouldn't it be 50% of $14k?
