You subject line says "round up to 50", which is different from "round
to the nearest 50". Which is it?

One way to round to the nearest 50:

=mround(A1,50)

If you get a #NAME? error, use Excel Help to find information on how
to use the MROUND function.

Alternatively:

=round(A1/50,0)*50

That also makes it easy to round up or down to a multiple of 50:

=roundup(A1/50,0)*50

=rounddown(A1/50,0)*50

One of those solutions should work for you.
