How much does an interpreter cost? In 2026, expect roughly $1 to $3 per minute for phone interpretation, $1.50 to $4 per minute for video, and $45 to $150 per hour for on-site work, according to published vendor rates. The rate, though, is the least useful number in the quote.
What actually sets your bill is the billing model behind that rate: per minute, per hour, or per session. Choose the wrong one for how you use interpretation and a low rate quietly becomes the expensive option.
That is where the worry lives. You want a defensible vendor decision, not a surprise bill from connection fees and rounding you never saw. This guide shows you how each model works, the fees that inflate a low headline rate, a break-even rule for matching the model to your usage, and examples of when each model is the right call.
On-demand interpretation uses three billing models. Each fits a different situation.
Per-minute billing covers phone interpretation, called telephonic or over-the-phone interpretation (OPI), and video calls with an interpreter, called video remote interpreting (VRI). You pay only for the minutes you use, which suits short, unpredictable calls.
Hourly billing covers on-site interpretation and some scheduled remote work, almost always with a minimum number of hours.
Per-session or flat-rate billing covers all-day assignments, conferences, and some scheduled legal or medical work. It's quoted as a half-day or full-day rate per event.
The numbers below are typical 2026 ranges. They come from published vendor price lists and industry guidance, not from a survey or a standard. Rates move with language, certification, region, and specialty.

The models are not interchangeable. A five-minute phone question and a full-day deposition aren't the same purchase. Comparing their headline rates tells you nothing on its own.
A low per-minute number is the easiest figure to advertise and the easiest to misread. A stack of modifiers sits on top of it.
A low headline rate of near $0.95 per minute can end up much higher on a short call. A per-connection charge and a per-call minimum both add to the total: a two-minute call billed at a four-minute minimum is already double the advertised rate, before the connection charge is even counted.
The other inflators are predictable once you know to look. After-hours, weekend, and holiday calls often carry a surcharge. Video and phone platforms can add technology or platform fees for licensing, routing, and integration. A low headline rate doesn't include those costs.
On-site work adds travel costs too. Vendors typically bill mileage at the IRS rate once the round trip passes a threshold of roughly 25 to 30 miles. They often bill travel time at a reduced rate once a trip runs long. Public fee schedules, like California Code of Regulations, Title 8, Section 9795.3, set both a mileage threshold and a travel-time rate of this kind. While none of these fees are scams, a quote that leaves them out can be misleading.
The right model depends on your usage pattern, and the trickiest call is per-minute versus hourly. One quick calculation settles it.
To find the crossover between per-minute and hourly, divide the hourly minimum by the per-minute rate. An on-site interpreter at $100 per hour with a two-hour minimum will cost $200 before anyone speaks. At $2/minute, that same $200 buys 100 minutes of phone time.
If your interaction is remote-appropriate and runs under roughly an hour and a half, per-minute almost always wins. If it needs to be in person or runs longer, the hourly minimum starts to pay off. Run that one division against any two quotes and the "cheaper" rate often flips.
A $1.25-a-minute quote tied to a contract is a real trade, not a trick. The question is whether the trade fits you.
A discounted rate tied to a contract usually asks for something in return: committed volume, a monthly minimum, or a term commitment. If you run steady, high-volume interpretation every month, that commitment can genuinely lower your per-minute cost. The discount is earned. If your usage is light or spiky, the same contract turns into a monthly minimum you pay whether you use it or not. The discount quietly disappears.
A standard per-minute rate with no contract looks more expensive on paper. In practice, it costs less for irregular use, because you pay for the minutes you actually use, not a committed block. A buyer with unpredictable volume isn't locked into minutes they may never spend. Match the commitment to your real volume, not the advertised rate.
These are illustrative scenarios, not a personalized quote. They show how the math tends to break for a given usage pattern. Your real total depends on the language, specialty, timing, and volume.
Per-minute fits short, unscheduled calls. Say your front desk fields about 20 short interpreter calls a month, each around six minutes, 120 minutes in all. At Argo Translation's phone rate of $1.95 per minute, with no nights, weekends, or holiday surcharge to inflate it, that runs about $234 for the month. Booking an on-site interpreter for each call would instead trigger a two-hour minimum every time, roughly $200 a visit at $100 an hour, or about $4,000 across the 20 calls, for conversations that last six minutes each. For quick, on-demand contact, per-minute is the clear winner.
Hourly fits scheduled, in-person appointments. Say you have a 90-minute specialist visit that needs an interpreter in the room. An on-site interpreter carries a two-hour minimum. At the $100 to $140 an hour that certified medical work tends to run, that is roughly $200 to $280, more predictable than metering a live exam, and a per-minute phone line isn't a real substitute when the interpreter needs to see the patient. For a known, in-person block, hourly wins.
Per-session fits all-day and conference work. Say you have a full-day training or an all-day deposition. A half-day or full-day flat rate caps the cost of the whole event up front. Paying by the hour or by the minute across eight hours would climb much higher and leave you exposed to overage as the day runs long. When the work fills a day, a per-session rate is the safer bet. For a large event with a multilingual audience, an AI speech translator sold in hourly bundles can deliver live captioning in many languages at once, a fit for audiences following along rather than for high-stakes exchanges.
You can fairly compare any two quotes by having every vendor answer the same questions. Before you sign, demand each of these line items in writing:
A vendor that answers all eight in writing is quoting you the real price. A vendor that will only quote the headline rate is quoting you the beginning of the price.
With those questions in hand, the pricing gets simpler. The real choice is between billing models, not between headline rates. Match the model to your usage pattern, and read the minimums and fees behind the headline number. The cheapest per-minute rate usually turns out not to be the lowest total cost once you do.
If you're comparing quotes right now, Argo Translation will give you a transparent, no-contract quote with every line item explained, backed by certified, HIPAA-trained interpreters, so you can weigh it like-for-like against the others on your desk.
