A rate card is not a number. A rate card is a one-page document that lets a hospital scheduler, a court clerk, or a school district coordinator know the total cost of an interpreted encounter without calling you. Buyers who have to call you to figure out cost will pick the interpreter who publishes their rate.

The four line items most interpreters forget
Specialty surcharge. A legal deposition is not the same cognitive load as a primary care visit. If you’ve done CME or specialized training, your specialty rate reflects it. Without a surcharge, you’re invisibly subsidizing the harder work.
Travel time, not just mileage. A 90-minute drive each way to a two-hour appointment is six total hours of your day. Mileage covers the gas. Travel time covers your time. Bill it.
Minimum billable across modalities. A 30-minute OPI call gets billed as the one-hour minimum or it doesn’t get accepted. The scheduler will respect this. Stating it once in writing is worth more than re-negotiating it on every booking.
Annual rate increase clause. Add one line: “Rates effective [date]. Annual review every January.” Without it, you’ll be charging 2023 rates in 2027 because nobody on the buyer side will proactively raise them.
