Over the Phone Interpretation Services Pricing and Telephone Interpreting Rates per Minute

Over the phone interpretation services cost $1.25 to $4.00 a minute at the retail rates US providers publish in October 2026, and $0.47 to $0.75 a minute on public state contracts. For a clinic or support team using 300 Spanish minutes and 40 minutes of rarer languages a month, the published plans range from $445 (Day Interpreting) to $1,343 (LanguageLine pay as you go). The monthly bundle, the minimum per call and the rare-language surcharge decide where you land, not the headline rate.

We checked the pricing pages of 30 over the phone interpreting (OPI) providers on October 6, 2026, from their own websites. Twelve publish a usable per-minute rate. The large enterprise vendors publish nothing, so for them we read the rates they agreed to on public state contracts instead, which is the only place those numbers are visible. No figure below comes from a software directory or a vendor blog quoting "industry averages".

Which over the phone interpretation services publish a price?

The providers that publish are mostly self-serve services aimed at small practices, law offices and support teams that do not want a contract. The large healthcare and enterprise vendors quote privately. Both groups are in the table, because a "no published price" row is useful to know before you book a sales call.

Two patterns stand out. First, the published rates cluster in two bands: $1.25 to $2.00 for services that sell on price, and $2.83 to $4.00 for services that sell on instant access with no commitment. Second, almost every name you would see in a hospital RFP (Propio, LanguageLine's enterprise service, CLI, AMN, Martti) publishes nothing. If your volume is above a few thousand minutes a month, you will be quoting with them anyway, and the state contract rates below are your best reference for what to ask.

What 340 minutes a month costs on each plan

Per-minute rates only compare cleanly once you add the monthly fee and the language mix. The table prices one realistic month for a US clinic, law office or support team: 300 minutes of Spanish and 40 minutes of a less common language such as Vietnamese or Haitian Creole, on every plan that publishes enough to calculate.

The spread is three to one for the same minutes. Over a year that is $5,340 at the bottom and $16,116 at the top, which for a small practice is the difference between a line item and a hire. The ranking also shifts with your mix. Jeenie's rare-language rate on Connect is 2.5 times its Spanish rate, so a team whose calls are mostly in rare languages should price on Plus or Premium or on a flat-rate service like Link Translations, which advertises no rare-language surcharge at all.

Where do the Jeenie plans cross over? On Spanish alone, Plus pays back against pay as you go at 70 minutes a month ($49 divided by the 70 cent saving), and Premium beats Plus above 250 minutes ($100 more for a 40 cent saving). A team at 340 minutes is past both lines, which is why Premium edges out Plus in the table.

Why public contract rates are a third of retail

The large vendors that publish nothing on their websites do publish, indirectly, when they win a government contract. State procurement agencies post the signed rate sheets, and those are the closest thing to a real enterprise price list in this market.

The contract rates sit between $0.47 and $0.75 a minute, roughly a third to an eighth of the retail rates above. For scale, the Bureau of Labor Statistics puts the median pay of interpreters and translators at $28.93 an hour (May 2025), which is about $0.48 per minute of paid time. Contract pricing is close to the interpreter's wage; retail pricing pays for instant connection, card billing and no commitment.

A private company cannot buy off a state contract, but it can use these figures in a negotiation. If you expect more than 1,000 minutes a month, ask Propio, LanguageLine, CLI or AMN for a quote and put the NASPO medical rate ($0.66) on the table as the reference. A clinic at our 340-minute example would pay about $224 a month at that rate, against $445 on the cheapest self-serve plan.

How much does an over the phone interpreter cost per minute?

An over the phone interpreter costs $1.25 to $4.00 per minute from US providers that publish a self-serve rate in 2026, with Spanish at the low end (Day Interpreting $1.25, Jeenie Premium $0.89 plus a $149 monthly fee) and instant no-contract access at the top (LanguageLine $3.95, LA Translation $4.00 with a one-hour minimum). Contracted enterprise rates run $0.47 to $0.75.

Is phone interpretation cheaper than video remote interpreting?

Usually, yes. LanguageLine charges $3.95 a minute for audio and $4.95 for video, and the NASPO contract prices general OPI at $0.56 against $0.75 to $0.85 for Spanish video. Jeenie is the exception: it charges the same rate for video and audio on every plan. Choose video when you need ASL or when the conversation depends on showing a document or a device; for everything else the phone is cheaper.

Do interpreting services charge more for rare languages?

Some do and some do not, and this is the line to check before you sign. Jeenie charges $4.99 for rare languages on pay as you go against $1.99 for Spanish, and Day Interpreting charges $1.75 against $1.25. LanguageLine, Lionbridge, Link Translations and the NASPO contract charge one flat rate for every language, and Link states there is no surcharge for rare languages or after-hours calls.

Is there a monthly minimum for phone interpreting?

Most self-serve services have none. Day Interpreting, Jeenie Connect, Interpreter.com, Lionbridge and LanguageLine Personal Interpreter all bill only the minutes used. The bundled plans (Accentable, 1-800-Translate, Link Translations, GLOBO, Jeenie Plus and Premium) charge a monthly fee whether you call or not, and Jeenie's Enterprise tier starts at 2,000 minutes a month.

Five billing terms that change the bill

The rate per minute is printed on the page. These five terms usually are not, and each one can move a monthly invoice by 10% to 50%.

• Minimum per call or per session. LA Translation bills a one-hour minimum on scheduled sessions, so its smallest charge is $240. AALV on the Vermont contract has a 10-minute minimum. A five-minute pharmacy call billed at a 10-minute minimum costs double.
• Rounding. Interpreter.com rounds up to the next minute, and the California contract rounds to the nearest full minute. Most providers only say "per minute used". Rounding up on a 6 minute 10 second call bills 7 minutes, 13% more than the call lasted. Ask whether billing starts when the interpreter answers or when you dial.
• Unused bundle minutes. Accentable's 10 included minutes expire after a month and the 30-minute starter pack after six. Link Translations' $19.81 buys 7 minutes, which is $2.83 a minute only if you use all seven. Day Interpreting's prepaid credits never expire, which matters for a practice with uneven months.
• Three-way and conference calls. Day Interpreting adds $0.25 a minute for each extra party. If your workflow is a patient, a nurse and an interpreter on one call, ask every provider how the third leg is billed.
• Specialty and after-hours tiers. The NASPO sheet charges $0.10 more for medical and $0.19 more for legal than for general calls, and another $0.10 outside standard hours. Retail services mostly hide this inside a single rate; enterprise quotes usually split it out.

If the sessions are scheduled rather than on demand (a deposition, a parent-teacher conference, a follow-up visit), the minimum per session matters more than the rate, and the interpreter's time slot has to be locked to the client's. A shared booking page that lets the client pick the interpreted appointment slot keeps a no-show from turning into a billed hour.

Which phone interpreting services are HIPAA compliant?

For US healthcare buyers, Section 1557 of the Affordable Care Act requires covered health programs to offer qualified interpreters to patients with limited English proficiency at no cost to the patient, so the provider you pick has to handle protected health information properly. Among the services that publish prices, Jeenie Plus and Premium state HIPAA-certified interpreters while Jeenie Connect says HIPAA interpreters are not guaranteed; Day Interpreting has a HIPAA page; Accentable says it is committed to HIPAA. AMN and Martti market to hospitals and state HIPAA compliance.

A HIPAA page is not a Business Associate Agreement. Before your first patient call, ask the provider to sign a BAA, confirm interpreters are bound by confidentiality in writing, and ask whether calls are recorded and where recordings are stored. A provider that will not sign a BAA is not an option for patient calls at any price.

When an interpreter line is the wrong purchase

An OPI account is the right tool when you already have staff on the phone and need a third voice in the call. It is the wrong tool in three situations.

When the problem is answering the call in the first place. If Spanish-speaking callers reach voicemail after hours, an interpreter line does not help, because nobody is there to conference one in. A bilingual answering service that takes the call in Spanish is the fix, and we compared what those cost in our guide to bilingual answering service pricing. For general overflow and after-hours coverage, see our answering service pricing comparison.

When one language dominates. At our example volume of 300 Spanish minutes a month, the cheapest published plan costs about $5,300 a year. At ten times that volume, interpreter minutes start to cost as much as a bilingual agent, and hiring or training one becomes the cheaper path. The call center staffing calculator shows how many bilingual seats a given call volume needs once shrinkage is counted.

When the call can route itself. A phone menu that offers "para español, oprima dos" and sends those calls to a Spanish-speaking queue removes the interpreter from the most common calls entirely. The menu itself is cheap; the published rates are in our IVR system cost guide.

Machine interpretation is the newest option, and it is not yet cheap. Wordly, one of the few AI interpretation vendors with a public price, sells about 10 hours for roughly $1,500, around $2.50 per session minute, and it is built for meetings and events rather than one-to-one patient or customer calls. KUDO, Interprefy and Boostlingo's AI product publish no price.

What to ask before you sign an OPI contract

• The per-minute rate for Spanish, for your two most common other languages, and for ASL video, in writing.
• Whether there is a monthly fee or commitment, and what happens to unused minutes.
• The minimum per call and the rounding rule.
• Average connect time for Spanish and for a rare language at your busiest hour, and what happens when no interpreter is available.
• Whether medical, legal or after-hours calls carry a higher rate.
• How three-way calls and transfers are billed.
• A signed BAA if any call involves patient information.
• The cancellation notice period (Jeenie's paid plans require 30 days).

The short version

Twelve over the phone interpretation services publish a price, from $1.25 a minute (Day Interpreting Spanish) to $4.00 (LA Translation, with a one-hour minimum). For 340 minutes a month the published plans cost $445 to $1,343. The big enterprise vendors publish nothing, but their state contract rates of $0.47 to $0.75 a minute are public and make a strong anchor once you pass about 1,000 minutes a month. Check the minimum per call, the rounding rule, the rare-language rate and the BAA before you compare two quotes.
