ASM question

I started as a TM at tractor supply, went to TL and I’m currently a Receiver looking into getting the ASM position. My SM is asking for how much I want to get paid. I was under the impression that TM=$13~ Rec=14~ TL=15~ so ASM should be about 17-$18? When I went to receiver from TL I kept my pay just an FYI and will almost be there for 2 years now. Just wondering what I should ask for. Thanks.
