[Share] Retirement Benefit Tracker: a free tool for U.S. retirees

[chatfa]

I just launched Retirement Benefit Tracker: https://www.retirementbenefittracker.com/

It is a free, mobile-friendly resource for U.S. older adults who receive—or are preparing to receive—Social Security, SSI, and Medicare, as well as family members helping them navigate retirement benefits.

What it currently includes:

• Social Security and SSI payment dates, including annual calendars
• A COLA calculator to estimate how cost-of-living adjustments may affect monthly benefits
• A Medicare Part B calculator, including an explanation of the hold harmless rule
• Plain-language guides, calculation notes, common questions, and source references

The motivation is simple: payment schedules, benefit rules, and Medicare premium changes are often spread across multiple official sources and can be difficult to follow, especially for older adults. I wanted to put the most commonly needed information and calculators in one clearer place that works well on a phone.

This is an early version. Results are for informational purposes only and are not Social Security, tax, medical, legal, or financial advice.

If you have parents, relatives, or friends in the U.S. who are retired or nearing retirement, I would be grateful if you shared it with them. Feedback is very welcome—especially on which information or calculators would be most useful to add next.
