Client-intake automation cost calculator

Tally form to HubSpot contact and deal to Brevo acknowledgement, automated with Make, all on the free plans we tested (Tally Free, Make Free, HubSpot Free CRM, Brevo Free). Operation counts are measured in our test runs of 2026-08-16 and 2026-08-20. Prices and plan limits are vendor-sourced with the date we checked them. Defaults and thresholds are our own assumptions and are labeled as such.

Who this is for: a solo consultant or small agency sizing this exact workflow. Who can skip it: if you only need a form that creates a CRM contact, HubSpot's own free form builder does that without Make (checked on 2026-08-18) and this calculator does not apply.

Your numbers

The preloaded values are illustrative defaults, not benchmarks.

Form submissions per month Whole number. Everything that hits the form, including repeats.

Share that are duplicates (%) Same email submitting again, taking the 3-credit update path.

Share of new leads where the association step fails (%) v2 only. Modeled as the full chain plus one alert email (7 credits). Other handled failures we observed cost less, so this is conservative.

Workflow version In our v1 tests, both unhandled errors we provoked (a failed association call, a duplicate-create rejection) deactivated the scenario.

Where the numbers come from

Item	Value	How we know
New lead, full chain	6 credits	Measured in every healthy run (v1 on 2026-08-16, v2 on 2026-08-20)
Duplicate submission, update path	3 credits	Measured in v1 (case L003, 2026-08-16). v2 leaves those modules unchanged; the v2 value is an inference, not a new measurement
Handled association failure	7 credits (6 + 1 alert)	Measured once in v2 (case T2, 2026-08-20). A handled duplicate-create failure measured 4 credits (case T3b); the calculator uses the higher figure
Make Free	$0, 1,000 credits/month, 7-day execution log retention	make.com/en/pricing, checked on 2026-08-20
Make Core	$9/month on monthly billing, 10,000 credits/month, 30-day log retention	make.com/en/pricing, checked on 2026-08-20. Annual billing is discounted; not modeled
Brevo Free	$0, 300 emails/day	Limit shown at signup, checked on 2026-08-06. Re-check before relying on it
Tally Free, HubSpot Free CRM	$0	Plans used in testing, free at signup, checked on 2026-08-05 (Tally) and 2026-08-05 (HubSpot). Not a binding constraint at the volumes tested
80% "close to the cap" threshold, 30-day month for the Brevo average	assumptions	Our choices, not measurements

What this calculator does not know

It assumes one acknowledgement email per new lead, one alert email per handled failure, and no other scenarios on the same Make account. The Brevo check is a 30-day average and cannot tell you about a busy day. It does not model Make credit add-ons, annual discounts, HubSpot paid tiers, or your time. Every v2 figure comes from a single observation per case. In v2, a handled association failure leaves the deal unlinked to the contact, and a handled duplicate drops the newer submission's data instead of merging it. Prices and limits change; the dates above say when we last looked.
