Insurance Fee deduction computation

My company deducted us an amount of about NT$1300 per month for the total of 3 insurance fee(Health, Labor, Welfare). Do you have an idea on how to compute the 3 insurace fee based from my Basic Wages NT$17880?

Health insurance for your responsibility : 244/mo.
Labor insurance for your responsibility : 286/mo.
Pension is not your responsibility (employer’s obligation)

Thanks for the reply. May I know what is the basis of computing the health and labor insurance fee? Our Basic Wages is NT$17880… By the way, if you have some article regarding the health and labor insurance fee computation can you share to me…thanks.
