# HSA Contribution Limit: Family Coverage vs Individual Coverage

Reader and fellow blogger Joe brought up an interesting point on my previous post about the 2015 HSA contribution limits. The contribution limit for family coverage is just \$50 shy of twice the limit for individual coverage.

 Individual Coverage Family Coverage 2013 \$3,250 \$6,450 2014 \$3,300 \$6,550 2015 \$3,350 \$6,650

Why would they do that instead of making it simply 2x?

Actually if we go back a few more years, it was just the opposite. The contribution limit for family coverage was \$50 more than twice the limit for individual coverage.

 Individual Coverage Family Coverage 2011 \$3,050 \$6,150 2012 \$3,100 \$6,250

Why would it be sometimes \$50 less and sometimes \$50 more? Wouldn’t it be cleaner if it’s just 2x?

It would be and it was when it started. The original limit was set to \$2,250 for individual coverage and \$4,500 for family coverage. Then the law says these limits must be adjusted for inflation, but rounded to the nearest \$50. The problem is somebody forgot to say the limit for individual coverage should be rounded to the nearest \$50 but the limit for family coverage should be rounded to the nearest \$100.

So we ended up with the 2014 limit for individual coverage at \$3,283, rounded up to \$3,300 and the limit for family coverage at \$6,566, rounded down to \$6,550. When one number rounds up and the other number rounds down, you no longer have the neat relationship of exactly 2x.

Someone goofed up the math. Now everyone bears the consequence.

Mortgage rates hit new lows. I saw rates as low as 3.25% for 30-year fixed, 2.625% for 15-year fixed, with no points and low closing cost. Check mortgage rates in your state.
