The 2017 Social Security COLA — 0.3%

Cost-of-living adjustment, 2017

0.3%

This adjustment was determined in 2016, took effect with benefits payable for December 2016, and first reached checks in January 2017.

SSA’s own table lists this adjustment under 2016, the year it was determined. The public name it by the year it reaches a check, which is one later. This site uses the name people search for. Why the two labels disagree.

This is one of the two proof years

The base quarter here is Q3 2014, not the third quarter of 2015. The rule measures against the last year in which an adjustment actually became effective, and 2015 produced none. A naive year-over-year computation on this year is wrong, and it is wrong by enough to change the published figure. The rule, and the error it prevents.

The CPI-W values behind the 0.3%

Every adjustment is an average of three monthly index readings against an average of three others. These are the six values, as the Bureau of Labor Statistics published them for series CWUR0000SA0 — all items, U.S. city average, not seasonally adjusted.

The quarterly averages are rounded to three decimal places — the precision the determination-2016 notice specifies — and the percentage increase between them is then rounded to the nearest tenth of a percentage point. That gives 0.3%.

Reproduced from the raw index

Recomputing this adjustment from the committed CPI-W series returns 0.3%, matching SSA’s published figure. That check runs on all 51 determinations as a blocking build gate, so no page here can ship a figure the arithmetic does not support.

What 0.3% did to a benefit

Monthly benefit amounts are floored to the whole dollar after the adjustment is applied, which is why these figures are not simply the percentage multiplied out.

Effect of the 2017 adjustment on two benchmark monthly benefits
Monthly benefit beforeAfter the adjustmentMonthly increaseOver a year
$1,000$1,003+$3+$36
$2,000$2,006+$6+$72

Medicare changes the answer. In 2017 the Part B standard premium was $134.00 against $121.80 the year before, so a $2,000 benefit gained +$6 gross but only +$0 net — an effective raise of 0.00% against a headline 0.3%. The full ledger for that amount.
