401K Plan

Its through Charles Schwab and transferable.

My first 401k so far, filling up nicely.

Put in a significant amount and good rates

Seems good enough with a good choice of index , bonds and international exposure.

The longer you stay, the more Apple matches and they also extend it to part-time employees

Matching first day at 50%, 2nd year at 75%, 4th year at 100%

They match up to a percent which is good.

It matches the 3% at the beginning and then it will gradually increase

Typical 401K plan. The matching dollars vest immediately (no waiting years for the matching funds to truly become yours). Your first two years at the company you can get a match of 3% of your salary (50% match on up to 6% of salary contributed to 401K), then in the 3rd-5th year you get up to a 4.5% of salary match (75% match on up to 6%), and after the 5th year you can get a match on the full first 6% of your salary that you contribute to the 401K. Note, they base the match off the first 6% of gross salary contributed to the 401K in each paycheck, NOT on an annual basis. That means you can't front-load all your 401K contributions early in the year and still get the full match, instead you must spread contributions equal to at least 6% of your salary out over the entire year to get the maximum matching contribution.
