Nobody tells you about the ongoing costs. For salt-based systems, you’ll buy bags of salt every month. That’s about $5 to $15 per bag, maybe one bag per month for a family. So budget roughly $60 to $180 a year just to keep the magic alive.

You’ll also need a pre-filter if your water has sediment (dirt or rust). That costs another $30 to $100 and then $20 every few months for new filters. It’s like a subscription for your pipes, but without the annoying auto-renewal emails.
Oh, and if you rent? You can also lease a water softener for $30 to $50 per month. That covers maintenance and repairs, but you never own it. It’s like dating a water softener instead of marrying it.
The “Wait, Do I Even Need This?” Check
Before you spend a dime, get a simple water test kit ($15 at a hardware store). If your hardness is under 7 grains per gallon, you might not need a softener at all. If it’s over 10 grains, your hair will soon evolve into a Brillo pad.
Also, water softeners can be bad for garden plants because of the salt. So if you’re a proud plant parent, you might need a bypass or a separate hose bib. Sorry, ficus.
