How much hike % I can expect switching a company after 4 months of joining. The salary offered was low, i took the offer as i was unemployed

I was laid off in Jan and joined another company in March. Since I was unemployed and no offer at hand , this company offered a low ctc but I took the offer even though i was a completely different domain. Now I again considering to attempt another switch due to increased financial liability. How much hike I can expect after leaving a company within 4 months of joining.
