There’s no way around it — learning to fly is not inexpensive. You’re renting a helicopter and paying for your instructor’s time. You can expect to pay between $11,000 and $16,000, depending on where you live and how many hours it takes you. The good news is that at many schools, you pay as you go.
If you want a career as a helicopter pilot, you will need additional certificates (commercial or higher), which will require additional training and additional cost.
