Thanks for you reply

I already have two other options for shipping method and payment methods which appears as radio option on checkout page.So i think your solution will not work for me.
Could you please help me if you thinks its possible in hikashp?
Thanks in advance

Hi,

A solution could be to use the coupon, set a negative amount in the coupon, and in the options in Configuration > Checkout make the coupon as auto loaded in checkout.

Or you can potentially make a little plugin which will add this fixed amount to the order.
And editing the view "checkout / cart" will allow to display this amount directly in the checkout.

Here is some documentation for the plugin:
