When something serious is going on, like a custody battle, a suspected affair, or missing financial information, hiring a private investigator can feel like your last resort. But how much does a private investigator actually cost?
In most cases, you can expect to pay anywhere from $25 to $250 per hour, or $225 to $850+ for flat-rate services, depending on the complexity of the case, your location, and the investigator’s experience.
This guide breaks it all down for you: average pricing, what affects those prices, how different services are billed, and whether a flat rate or hourly fee makes more sense for your situation.
Let’s walk through the numbers so you can make an informed decision, without wasting time or money.

Several factors influence what you’ll ultimately pay:
Hourly Services include | Flat-Rate Services are typically for |
Surveillance | Background checks |

Boston, MA | $146 |
New York, NY | $138 |
Los Angeles, CA | $121 |

Hiring a private investigator is never an everyday decision. It usually comes at a time when trust is broken, safety is in question, or legal battles are looming.

Whether you’re fighting for custody, dealing with suspected infidelity, or trying to recover assets, the right investigator can bring closure and peace of mind.
But don’t rush into it. Ask questions. Get a detailed breakdown of costs. Make sure the investigator is licensed and experienced in your type of case.
At the end of the day, it’s not just about what a private investigator costs, it’s about the value of the truth you’re trying to uncover.
