What's my spring rate?

2.5 inch coil spring
12mm(corrected)
7.25 length
7 coils total

I used an online calculator and came up with 519#. Does this sound correct?

are the end coil conditions part of the 7 or no?

Total coils include the flat ends. I think that's 5 active coils. The wire diameter is .47 inches
