Solo 401k Contribution Limits

[Chai Jonn]

Hello All,

I have opened a Solo 401k Account last year. I have self employed income for 2018 and 2019. I like to contribute to both 2018 and 2019 this year. I have filed for extension for taxes for 2018. I am getting different numbers using different calculator for solo 401k contribution.(sole proprietor)

Is the below correct?

2018....Net Income...........         $26496

Employee Contribution Max :  $18,500 

Employer 20% :                          $3062.06

2019....Net Income...........         $31000

Employee Contribution Max  : $19,000

Employer 20% :                          $4,904.96

Do I have the correct numbers?

Thanks

Chai
