Owning a toy crane machine involves several ongoing monthly expenses beyond the initial purchase and buying new prizes. First, electricity is a constant cost. While a single machine doesn't consume a massive amount, it adds to your utility bill, especially if it's running 24/7. Second, regular maintenance is crucial. Components like the claw mechanism, joystick, and coin acceptor can wear out, requiring occasional repairs or part replacements to keep the machine operational and safe. Third, depending on your business model, location rental fees can be a significant monthly outlay if you place your machine in a mall, arcade, or restaurant. You might pay a flat fee or a percentage of the revenue. Fourth, consider transaction fees if your machine accepts digital payments or credit cards through a payment processor. Finally, while not strictly monthly, budgeting for periodic prize restocking is an essential recurring cost of operation. Planning for these expenses ensures your crane machine remains a profitable and enjoyable investment.
