The cheapest toll-free tracking number isn't the one with the lowest per-minute rate
Toll-free minutes cost more than local and the rate hides in plan notes — but once you add the monthly base, the per-minute leader can be the most expensive way to run a toll-free number.
Ask which call-tracking platform is cheapest for toll-free numbers and the honest answer has two halves, because toll-free billing has two meters: a per-minute rate and a per-number monthly fee. The per-minute rate runs higher than the local equivalent, and it doesn’t show up on the headline pricing tile — it lives in plan notes. The lowest published toll-free per-minute rate in our dataset is $0.055/min, charged by both Dialics (pay-as-you-go) and Ringba’s Professional tier. On the per-number side, only one vendor in our dataset publishes a fee specifically for a toll-free number: Dialics at $2/mo (its local numbers are $1/mo). Everyone else either folds the toll-free number into the base, publishes only a local-number fee, or quotes a general per-number fee that isn’t broken out for toll-free. But the low per-minute rate and the low base fee rarely sit on the same plan, which is the whole point.
The per-minute and per-number rates, surfaced
Here is what each vendor that publishes a toll-free rate actually charges, with the monthly base it rides on top of:
| Vendor / plan | Monthly base | Toll-free /min | Toll-free number /mo |
|---|---|---|---|
| Dialics — Pay As You Go | $0 | $0.055 | $2 |
| Ringba — Professional | $297 | $0.055 | not published (local $2) |
| Ringba — Business | $147 | $0.06 | not published (local $3) |
| CallRail — Lead Tracking | $50 | $0.065 | — |
| WhatConverts — Call Tracking | $30 | $0.065 | — |
Two things jump out. First, the spread on the per-minute rate is narrow — $0.055 to $0.065, an 18% band — so the rate alone won’t decide much. Second, CallRail and WhatConverts both charge $0.065/min for toll-free against $0.045/min local; the toll-free premium is roughly 44% and it’s stated nowhere on the pricing page, only in the usage footnotes. That premium is the real story for anyone routing volume through a 1-800 line.
A note on the per-number column, because it’s where most comparisons go wrong. Ringba publishes a local number fee — $3/mo on Business, $2/mo on Professional — but it does not publish a separate toll-free number fee, so we leave its toll-free per-number column unstated rather than borrow the local figure. Dialics is the only vendor in the dataset with a stated toll-free number price ($2/mo), which makes it the cheapest toll-free number fee on offer by default — there is nothing else to compare it against.
For reference, Convirza publishes general per-number fees of $3.00 (Starter, $29/mo) and $1.00 (Agency, $149/mo) and quotes its $0.08/min and $0.05/min rates as general per-minute charges, none of it broken out for toll-free specifically — so it can’t be ranked on a toll-free rate or a toll-free number fee honestly, only on its general per-number fee.
Why the per-minute leader is a trap
Ringba Professional ties Dialics on the per-minute rate ($0.055/min) — but it carries a $297/mo base. Fix a workload and the base swamps everything. At 500 toll-free minutes a month on a single number (using only toll-free fees the dataset actually publishes — Dialics adds its stated $2/mo toll-free number fee; Ringba publishes no toll-free number fee, so none is added):
- Dialics: $0 base + 500 × $0.055 + $2 toll-free number = $29.50
- WhatConverts: $30 base + (500 × $0.065 − $30 usage credit) = $30 + $2.50 = $32.50
- CallRail: $50 base + 500 × $0.065 = $82.50
- Ringba Business: $147 + 500 × $0.06 = $177.00
- Ringba Professional: $297 + 500 × $0.055 = $324.50
The plan with the lowest published per-minute rate is the most expensive way to run this workload — roughly eleven times Dialics — because at 500 minutes you spend just $27.50 on metering and the rest is subscription. Ringba’s per-minute advantage only pays off at the volume its pay-per-call buyers actually run, where minutes dwarf the base. For a marketer with one or two toll-free numbers and moderate traffic, the rate is nearly irrelevant; the base fee is the bill.
How to read this
If toll-free per-minute price is your literal question, the answer is $0.055/min, and Dialics is the only place you get that rate with no subscription standing in front of it — pure pay-as-you-go, $2/mo per toll-free number, which makes it the cheapest toll-free line in the dataset at any modest volume. If you want a named plan with reporting built in, WhatConverts at $30/mo is the cheapest base that meters toll-free at $0.065/min, and its $30 usage credit means light users may pay nothing extra at all.
Ringba’s $0.055/min headline is real, but it’s priced for buyers pushing enough minutes to amortize a $147–$297 base — not for someone tracking a handful of toll-free calls. The lesson the headline pricing hides: on toll-free, the per-minute rate is a rounding error next to the monthly base until you’re running thousands of minutes. Rank on the rate and you’ll pick the wrong plan. Rank on base-plus-usage at your real volume, and the order is almost exactly reversed.
