Adding (flat rate) shipping costs to the magento grand total in the shopping cart - Magento 1.9

Question

Currently my magento shopping cart only adds up all the prices of the products in the cart. Adds this up to a subtotal, and then displays the exact same amount to the grand total. This is not realistic, since I will charge a flat rate amount of shipment costs (Will always be the same amount: 5,95)

Administratively, I use prices excluding tax, to keep things simple. I will state in the bottom of the site that all prices are inclusive of tax.

I have been looking around, but no one seems to have this problem, or there are no answers.

So what I have now:
Subtotal: 22,50
Grand total: 22,50

What I would like:
Subtotal: 22,50
Shipping: 5,95
Grand total: 28,45

Answer 1

‘Subtotal’ and ‘Grand total’ are fetched from

app\design\frontend\your-package\ your -theme\template\ tax\checkout\subtotal.phtml file and grandtotal.phtml files respectively. Edit grandtotal.phtml file as per your need.

Answer 2

Are you sure that you entered the flat rate price correctly in the backend? Could you provide screenshots of that setting and also, how does you tax settings look? Check under
