I've recently went through the new player's "grind" (about 350 matches in), and I thought I'd share my experience.
I consider MWO a genuinely free-to-play game, in that you can get competitive mechs without paying a cent, only using the virtual c-bill currency and XP earned in-game. However, there's a bit of a grind to earn the required c-bills and XP.
To put some numbers on this, you need somewhere around 30 million c-bills to buy the required three variants of a given mech, with competitive loadouts. Assuming average c-bill earning of 100,000/match, and counting in ~10 million from cadet bonus from the first 25 matches, that's about 225 games played.
The final thing you'll need to make your mechs fully top-notch is to buy "modules" (bits of equipment that boost certain aspects of your mechs) for this. These need to be first "unlocked" by using GXP and then bought with c-bills. You'll need somewhere around 25,000 GXP to unlock the modules a mech can carry -- the module costs vary a lot so that's a ballpark figure. You might earn about 50 GXP per game, so that's 500 games played. By the time you've earned the GXP to unlock the modules you should have the c-bills to buy them too (unless you spent c-bills elsewhere), so here the GXP grind is the limiting factor.
So that's, at a rough estimate,
500 games for three mechs, with full bells and whistles. Equal to about 80 hours of play time at 10 minutes a match. In short, it really is free to play, but the grind is kind of bad and something you should be prepared for.
There's also one big caveat here: all of the above assumes that you work consistently on one chassis, buying the required three variants for that chassis, and unlocking the skills for those. All this will become much slower if you work on a mech, but then decide that it's not a mech for you and switch to another one. With that in mind, I'd
strongly recommend trying many of the "trial mechs" and decide what kind of a playstyle, and what kind of weapons you're most comfortable with. Once you've established the above, only then use your hard-earned c-bills on a mech that best caters to your chosen playstyle.
