Cost of replacing the electrical wiring in your house will vary from state to state and how big your house is and how much wiring needs done.
Another thing that can add to the cost of rewiring your house is how much work is involved to put the new wires in place.
If there's easy access to the attic where they can fish the wires through the walls through the attic then the cost would be less but if they have to do demo work or something else to get the wiring replaced then the cost can go up.
Cost to rewire a house though can range for $5,000.00 to $15,000.00 and up depending on how much work is involved and how much wiring is needed.
If you can do the wiring safely yourself then it might only cost $500.00 or $1,000.00 depending on what materials you will need.
