You don't say WHY you want to replace it - unless badly cracked with vertical offsets at the cracks (more than just shrinkage cracking) or literlaly falling apart, it may be an overlay or epoxy surfacing or such would solve the issue for you.

Bear in mind the concrete stepup is disproportionally expensive if simple wood step will work, because requires them to either precast it or come and do it separately - is not generally possible to do it concurrent with the slab pour.

Bottom line cost - assuming this is normal slab-on-grade with the garage foundation being OUTSIDE the slab and a full perimeter expansion joint around the outside of the slab - i.e separate wall foundations rather than the walls sitting on top of a thickened edge or post-tensioned slab, mahbe as low as about $5/SF at the low end, more likely around $6-10/SF in most areas, can run more like $10-13/SF in highest price areas or if there are complexities I do not know about.

Concrete - Pouring and Repair would be your normal Search the List category for this.

One after-thought - to avoid having to pay for garage door adjustment, be sure to specify (unless specific reason not to) that the slab elevation at the door shall be such as to prpperly match the existing garage door bottom seal when closed, if replacing thge concrete that the door seal to. (In conventional separate slab garage that would NOT be the case - the door would seal on the sill beam, which is part of the surrounding foundation.)
