Pricing pages in this category tend to lead with a monthly number and a per-minute rate, and leave the actual arithmetic to you. It's worth doing that arithmetic before committing, because the relationship between included minutes and overage rate changes the real cost more than the headline figure suggests, and the plan that looks cheapest on the label isn't always the cheapest one on the invoice.
The structure, plainly
Starter is ₹2,999 a month with 300 minutes included, and anything past that is billed at ₹5 a minute. Growth is ₹6,999 with 1,000 minutes included, overage at ₹4. Scale is ₹14,999 with 2,100 minutes included, overage at ₹3.75. The overage rate drops as the tier goes up, which is the whole reason a crossover point exists at all.
Where Starter stops being the cheaper option
Run the numbers month by month and the pattern is clear. At 600 minutes, Starter costs ₹4,499 against Growth's flat ₹6,999, Starter wins comfortably. At 1,000 minutes, Starter is ₹6,499 against Growth's ₹6,999, still cheaper. The gap keeps closing as usage climbs, and it closes to exactly zero at 1,500 minutes a month: both plans land at ₹8,999. Past that point, Growth pulls ahead. At 1,800 minutes, Starter is ₹10,499 and Growth is ₹10,199.
So the honest rule of thumb is this: below roughly 1,500 connected minutes a month, Starter is the cheaper plan. Above it, Growth is, and the gap widens the more you dial past that line. A lot of the "which plan should I pick" decision comes down to a fairly simple estimate of your own expected monthly volume against that one number.
Scale is a different kind of decision entirely
Here's the part that surprised us when we ran the same comparison against Scale: on pure per-minute economics, Scale doesn't actually overtake Growth until you're well past 2,100 minutes a month, more like the 16,000-plus range once you work through where the two overage rates cross. That's a volume most teams won't hit.
Which means Scale isn't really a "cheaper per minute" plan for most buyers. Its actual value is in what changes structurally: 20 concurrent calls instead of 5, 15 agents instead of 5, API access, two phone numbers included instead of one. If your bottleneck is concurrency, running more calls at once rather than fewer calls more cheaply, Scale is the right upgrade regardless of what the per-minute math says. If your bottleneck is genuinely just monthly spend at moderate volume, the math says stay on Growth longer than the plan names might suggest.
What isn't in the per-minute number at all
Ring time isn't billed. A call is only charged once someone actually answers, so a list with a lot of no-answers or voicemail doesn't quietly inflate the bill the way it would on a system that charges from dial rather than from connect. Worth remembering when you're estimating your own monthly minutes, since your "calls placed" count and your "billed minutes" count are two different numbers.
The practical takeaway
Estimate your actual connected minutes for a typical month, not your call volume, and check that number against 1,500. That single comparison tells you whether Starter or Growth is the better default, and it takes less time to work out than most people spend picking between two plans that, on paper, look nearly identical.
