Interest rates for Commercial RE?

Is there anywhere on the internet (or where ever) where I could find a mortgage calculator for commercial real estate loans?

I know that there are many more situations in terms of financing for commercial RE than financing a SFH, however, I am simply looking for information that could provide me with hypothetical, ballpark interest rates for commercial real estate.
