Bug In Online Social Security Benefits Calculator?
My plan was to wait until age 70 to collect my Social Security benefits based on getting an extra 8% per year for delaying. The figures shown on the Social Security web site don't line up with this. I am currently 68 years and 4 months old. The Social Security benefit estimator shows that if I retire in Jan 2024 I would receive $3851, in Jan 2025 $4113 and in Sep 2025 $4288.
Taking the Jan 2024 figure of $3851 and multiplying by 1.08 yields $4159 (vs the estimate shown online of $4113 for Jan 2025).
Taking the Jan 2025 figure of $4113 and multiplying by 1.0533328 (8 months at .0066666 increase per month) yields $4332 (vs the estimate shown online of $4288 for Sep 2025).
What am I missing here? This seems like it should be pretty basic math. The actual figure seems to
be 6.8% rather than 8%
