The Social Security Benefit Calculator is a free, embeddable calculator from CalcFunnel. Estimate your monthly Social Security benefit from your average indexed monthly earnings and the age you claim.
You enter 2 inputs: average indexed monthly earnings (AIME) and age you claim.
It returns estimated monthly benefit, benefit at full retirement (PIA) and estimated annual benefit.
Built for financial advisors and planners. Embedding it on your own website needs the Business plan (from $210/month, with a 14-day free trial), which unlocks the Retirement category.
The first figure — estimated monthly benefit — is the headline result.
Inputs
Each field below comes straight from the calculator, with the same help text visitors see when they hover the info icon.
