Dial math: one line against five.

A parallel dialer calculator for cold callers. Set your dials, connect rate and hours, and it works out conversations a day on one line against up to five on Five at a Time, and what the month costs at $150 a seat with 2,500 minutes included.

Lines ringing at once

5 lines is the mode called five at a time.

100 dials at 5.4% is 5.4 conversations a day on one line. On 5 lines the same hours hold up to 500 dials, so at most 27.

This is arithmetic on the numbers you set. It is not a forecast and it is not a promise.

  • Connect rate moves. It usually changes with the list and the time of day, so one slider setting will not hold all week.
  • Five lines is not five times the conversations. Multiplying dials by lines is an upper bound. It assumes every attempt takes the same time, and talking and wrap-up take the same time on any number of lines.
  • The meter counts answered calls, not talk time. Every answered call bills at least one minute, voicemail included. The minutes here use 0.93 billed minutes a dial, measured on DialSheet’s managed lines in early September 2026, over 21 working days, against the 2,500 minutes in a seat.

What goes in, in a sentence each

Dials a day on one line
How many numbers you dial in a day now, one after another. Count attempts, not conversations.
Connect rate
The share of dials that end with you talking to a person. It starts at 5.4%, the average Gong Labs measured in 2024. Yours is in your own call log, and it is the number to use.
Hours a day on the phone
The time you spend dialing and talking. It turns the totals into a pace: one conversation every so many minutes.
Lines ringing at once
How many numbers ring together. Five at a Time has four modes: solo is 1, double is 2, triple is 3 and five at a time is 5.

The sum, worked once

100 dials a day on one line, at a 5.4% connect rate, over 21 working days. Every figure is one of four multiplications.

  1. Conversations a day is dials times connect rate. 100 times 5.4% is 5.4.
  2. Dials on more lines is dials times lines, as a ceiling. It holds only if each attempt takes the same time, which talking and wrap-up do not allow.
  3. Billed minutes a month is dials times 21 working days times 0.93 billed minutes a dial.
  4. The month is $150 for the seat, plus 5 cents for each minute past 2,500. Divide it by the month’s conversations for the last column.

The one-line row is solo mode on Five at a Time. “At most” is the ceiling from the second sum, not a result anyone measured.

Numbers to set the sliders by

Three published studies, each named with its date and sample. They measure different things, so do not expect them to agree.

5.4%

Gong Labs, July 18, 2024

Across more than 300 million cold calls, the average rep connects with 5.4% of prospects. The top quartile connects with 13.3%.[1]

4.1

The Bridge Group, February 6, 2025

Across 351 B2B companies, the median SDR makes 44 phone activities a day and has 4.1 quality conversations a day.[2]

9.9%

Belkins, June 26, 2026

On more than 175,000 dials from 2025, 9.9% of dials connected, and about one meeting came from every 370 dials.[3]

What dialer vendors say about themselves

  • Orum says it has a platform-wide connect rate of 5.3% (2024).[4]
  • Nooks says “5x more dials, 4x more conversations, 3x more meetings”.[5]
  • Five at a Time publishes no such number. We are new and have none to publish, which is why this page asks for yours.

Those are claims by the companies selling the product. For how the two compare on things you can check, see Nooks vs Orum.

Where the money goes past 128 dials a day

The calculator turns dials into billed minutes at 0.93 a dial, which is what DialSheet’s managed lines averaged in early September 2026. At that rate the 2,500 minutes in a seat cover about 128 dials a working day.

Past that, each minute is 5 cents. One rep at 250 dials a day uses about 4,883 billed minutes and pays $269.15 for the month. Five lines at 100 dials each is the bottom row of the table: 9,765 minutes and $513.25.

The pricing calculator does the same sum for a whole team and lets you change the minutes per dial. How dialer minutes work explains why a voicemail costs a minute.

When the arithmetic says buy something else

Minutes are metered. There is no unlimited plan.

Trellus is the pick if you burn far more minutes than our plan includes: Trellus lists about 2,000 US minutes a seat a week at nearly the same price.[6] Its listed price is $149.99 a seat a month (Power + Parallel), and its page lists no free trial.

If the one-line row already covers your day, a power dialer does the job. Parallel vs power vs predictive has the dividing line, and the page for solo reps has the cheaper routes.

Calculator questions

How do I work out conversations a day from cold calls?

Multiply your dials a day by your connect rate. At 100 dials and a 5.4% connect rate, that is 5.4 conversations a day.

What is a good cold call connect rate?

Gong Labs, in a July 2024 study of more than 300 million cold calls, found the average rep connects with 5.4% of prospects and the top quartile with 13.3%. Belkins, on more than 175,000 dials from 2025, measured 9.9% of dials connected. Your list and the time of day move it.

Does five lines mean five times the conversations?

No. Five lines can fit up to five times the dials into the same ringing time, but talking and wrap-up take the same time on any number of lines. The five-line figure in the calculator is an upper bound.

How many dials a day do 2,500 minutes cover?

About 128 dials a working day, at the 0.93 billed minutes a dial measured on DialSheet's managed lines in early September 2026 and 21 working days a month. We make DialSheet too.

What does a month cost if I dial more than that?

Each billed minute past the included 2,500 is 5 cents. At 250 dials a day the same arithmetic gives 4,883 billed minutes and $269.15 for one seat.

Why does the calculator use billed minutes and not talk time?

Because the meter counts every answered call as at least one minute, voicemail included, and rounds each call up. On DialSheet's managed lines over the 30 days to October 23, 2026, the meter ran 2.25 times real connected time.

Is this a forecast of my results?

No. It is arithmetic on the numbers you enter. Five at a Time has not published performance numbers of its own.
