Adding percentage to a value using a helper?

I have the following existing helper in my Invoice model of my Rails application:

def total_price
  line_items.to_a.sum(&:full_price)
end

What I would like to do is have an additional helper called total_vat which adds 20% to the total_price helper. Is this possible?

I will eventually be adding a third helper which calculates the difference so I can print just the amount of VAT due.

Creating multiple helpers is absolutely possible.

def vat
  total_price * 0.2
end

def total_price_including_vat
  total_price + vat
end
