We created 2 widgets to show the cost savings of using flat fee and discount real estate services. Sometimes its helpful for potential clients to see exactly how much money they would save by using a flat fee or discount agent. Saving $4500 seems more significant than simply saving 2%. The problem is we can't list a dollar amount without knowing the house price and the house price is different for each client. This is where a calculator can be helpful. We created one for our site and figured it might be helpful for agents in other cities.
