Yes, Affordability depends upon your requirements. Do keep in mind that the cheapest does not always the best.

There are many companies who provides their services at a cheaper rate but according to me affordable web hosting means those services which can fulfill all of over needs without backing out any of the quality aspect in a worthy price.

In my view Affordable basically mean that any average person can pay for it. It should be usually within $15-20 with decent service. I am currently using Serveria, It’s definitely affordable for all with starting at $3.49 price and that too with amazing service with 99.99% Uptime guarantee for making us very calm and comfortable!
