Even if you do not use an online tool, plan extensively beforehand as to exactly what you plan to do. What color will the wall be? Will you put in any art? What flooring style will you go for? If your budget allows, you can consult an interior designer for recommendations. One advantage of such planning is that it allows you to set out a budget that you can work within, ensuring that you are not caught short of cash in the middle of your project.
You will need to obtain permits that meet the building codes in your area. Not only that, there are usually required permits for plumbing and electric work. Finally, once the basement is finished, it will need to be inspected in order to recalculate your home's value. If a contractor refuses to get a permit, DO NOT HIRE THEM. It's smart and it's the law.
Many new homes are built with an unfinished basement. This saves money up front in construction costs and gives a family the opportunity to grow into their home. A lot of people choose to finish their basement in order to add living space for entertaining guests or as a hangout area.

However, it's generally a good investment as a basement remodel fetches 80% to 90% of its investment cost at resale.
