It's cheaper to shoot digital if you don't factor in the cost of the gear.
As a f'rexample, you could pick up a decent film kit (two bodies, 28mm, 50mm and 135mm) for about £100 or less. (I'd have to go back through my
ebay purchases to figure out exactly how much my stuff had cost me, but I've never paid more than £20 for a lens, or £40 for a body).
Cost of film depends on what you shoot, but Fuji's superia costs £5 for 5 rolls in speeds from 100 to 400 from 7dayshop, and each roll costs me £3.50 to get developed to negative and scanned to cd. If I bought my own film scanner, that drops to £1.50 for development to negative and my time in scanning the negs in.
All of which is, of course, a complete red herring. What actually matters is what you like doing, and I find that some days, grabbing my OM-20 and going out shooting Fujichrome is what I want to do. It's less immediate than digital, (but then all my shots are perfect until I get them back from the lab
) and it does demand a different outlook than digital. In the same way, shooting with a medium format folding camera, or a 35mm rangefinder demands a different approach again.
I also like the colour and tonal range I get from film, but I daresay that sort of thing can be done with photoshop, if one is dedicated enough. I have a "Shot on film" set on my flickr, if you're interested;

I'm not sure that there is any point to it, tbh, beyond that I like it, which should be enough.
