Klaviyo cost estimator
Klaviyo bills on active profiles, not on the emails you send, so the list you are not even emailing still shows up on the invoice. Enter your active-profile count and this estimates your monthly email-plan cost from Klaviyo's published tiers, shows what your dormant contacts are costing you, and lets you add usage-based SMS. The math runs in your browser, and every rate is editable and shown.
Estimated monthly Klaviyo bill
$150/ mo
About $1,800 a year. Email plan $150/mo. That is roughly $15 per 1,000 active profiles.
The active-profile trap
You said you email about 60% of your profiles. Since Klaviyo bills on active profiles, the other 40% still cost you about $60/mo ($720/yr) for contacts you never message. Suppressing or deleting dormant profiles is the fastest way to cut a Klaviyo bill.
Email-plan prices are Klaviyo published list pricing by active-profile tier, verified June 2026, interpolated linearly between published tiers. SMS is usage-based and shown as an editable estimate. Mailchimp bills by total contacts and Brevo by monthly send volume, so a like-for-like comparison depends on your list size and how often you send. This is a planning baseline, not a quote.
Why your Klaviyo bill is bigger than your sending
In February 2025 Klaviyo shifted to billing by active profiles. An active profile is any contact in your account that is not suppressed or fully deleted, whether or not you ever email them. The practical effect: a list full of one-time buyers and old signups you never message still moves you up the price tiers. The published email-plan tiers run from free at 250 profiles to about $20 a month at 500, $100 at 5,000, $150 at 10,000, $400 at 25,000 and $720 at 50,000, before SMS or any add-ons.
That is why the single most effective way to cut a Klaviyo bill is rarely sending less. It is profile hygiene: suppress or delete the dormant contacts you will never email, and you drop tiers without losing a single engaged subscriber. The tool above puts a number on exactly that.
How it compares to Mailchimp and Brevo
The three platforms bill on different units, which is why a flat price comparison misleads. Klaviyo charges by active profiles. Mailchimp charges by total contacts, including unsubscribed ones on some plans. Brevo charges by monthly send volume and lets you store unlimited contacts, which tends to win for large lists that send infrequently. Whether Klaviyo is expensive for you depends on your list size and how often you send, so compare on your own numbers rather than on a headline tier price.
Who this is for
Ecommerce and DTC operators sizing or auditing a Klaviyo bill, and anyone deciding whether their list has grown faster than the value they get from it. If you would rather have the whole stack built and run for you, that is exactly what Mue does.
The numbers here are a planning baseline, not a quote. SMS pricing, add-ons and any negotiated rate will differ, so confirm against your own Klaviyo account before you plan around it.
Klaviyo pricing questions, answered
How much does Klaviyo cost per month?
Klaviyo's email plan is free up to 250 profiles, then about $20/mo at 500 profiles, $30 at 1,000, $100 at 5,000, $150 at 10,000, $400 at 25,000 and $720 at 50,000, before SMS or add-ons. It bills on active profiles, not on emails sent, so the calculator estimates your tier from your profile count.
How can I lower my Klaviyo bill?
Because Klaviyo bills by active profiles, the fastest cut is profile hygiene: suppress or delete contacts you will never email, which can drop you a whole tier without losing a single engaged subscriber. Sending less email does not lower the bill; carrying fewer dead profiles does. The calculator shows what your dormant profiles currently cost.
Is Mailchimp cheaper than Klaviyo?
It depends on your list and how you send. Klaviyo bills by active profiles, Mailchimp by total contacts, and Brevo by monthly send volume with unlimited stored contacts. For a large list that sends infrequently, Brevo or Mailchimp can be cheaper; for engaged senders the gap narrows. Compare on your own profile count and send frequency rather than a headline price.
Why is my Klaviyo bill higher than I expected?
Most often because Klaviyo moved to active-profile billing in February 2025: every contact you store and have not suppressed counts toward your tier, even ones you never email. A list full of one-time buyers and old signups quietly pushes you up the price tiers, so the bill tracks list size, not sending.
The data-story behind this tool
Your Klaviyo bill is mostly contacts you never emailAt 10,000 profiles Klaviyo runs about 150 dollars a month, but if you only email 6,000 of them the other 4,000 cost you about 720 dollars a year for nothing. Since 2025 Klaviyo bills on profiles, not sends.
