Slido Pricing Explained: Annual Plans vs One-Time Event Plans (2026)
Slido pricing (as of October 2026) has a free Basic plan (100 participants, 3 polls per slido) and paid plans sold two ways: annual subscriptions billed yearly with no monthly option, or one-time plans for a single event of up to 7 days, priced by participant tier. "How much does Slido cost?" has a longer answer than the pricing page suggests, because the number you pay depends less on the plan and more on how Slido bills. There is a free Basic plan and three paid tiers — Engage, Professional and Enterprise — but Slido does not sell a monthly subscription. For a paid plan you either commit to a full year, or you buy a one-time event plan for a single event, priced by how many people will join. That structure is fine if you present every week and awkward if you run two or three events a year. This article lays out what each plan includes, the annual and per-event figures reported across pricing sources (they vary, so treat them as a guide and confirm on Slido's own page), the participant caps that quietly decide your tier, and the simple break-even math for choosing between a subscription and paying per event.
- There is no monthly plan: a paid tier is billed annually, or you buy a one-time event plan for a single event
- Reported annual figures vary by source: Engage around $150–210/year, Professional around $600–900/year, Enterprise around $1,800–2,400/year — confirm the current numbers on Slido’s pricing page
- One-time event plans cover a single slido live for up to 7 days, priced per event by participant tier (commonly cited around $80 and $250, higher for the largest rooms)
- For a few events a year, compare the annual total against per-event — and against a flat pay-per-use tool like ZENIN CLOUD ($70 for 7 days, $10/day) with no annual commitment and no plan-based participant cap
Slido plans at a glance
The short answer: four plans, and the annual catch
Slido has four plans. Basic is free. Engage, Professional and Enterprise are paid, and they step up mainly on two things: how many participants can join a single event, and which advanced features (moderation, analytics, branding, integrations) unlock. Roughly, the participant ceiling climbs from 100 on the free plan to about 200 (Engage), 1,000 (Professional) and higher on Enterprise.
The catch that trips up most buyers is not the price but the billing. Slido does not sell a monthly plan. A paid tier is billed for a full year, or you buy a one-time event plan for a single event (Slido Community — why Slido doesn't offer monthly pricing). So the real question is not "which tier" but "subscription or per-event", and that depends entirely on how often you run events — which is what the rest of this article works through.
Third-party listings disagree on Slido's exact figures, and the vendor does not publish a single crawlable price for every tier. The numbers below are the most consistent readings across sources; use them to frame the decision, then confirm the current price on Slido's own pricing page before purchasing.
What each plan includes
The jump between tiers is driven by participant capacity first, then by the features a professional event needs — question moderation, deeper analytics and exports, custom branding, and tighter meeting integrations.
Unlimited audience Q&A, up to 100 participants per event, 3 polls and 1 quiz per event. No question moderation before the screen and no data export — those are paid. Good for small internal sessions and for testing. (Full detail in the free-plan breakdown linked below.)
The entry paid tier, commonly cited around a 200-participant cap, with unlimited polls, question moderation and analytics/export. This is the plan most single-team events land on.
Steps the cap up to roughly 1,000 participants and adds more presenters/collaboration, advanced analytics and branding — aimed at larger conferences and company all-hands.
The largest rooms plus org-level controls (SSO, admin, security review, dedicated support). Priced on a quote in many listings.
Two features worth singling out because they decide real events: question moderation (holding submissions for approval before they appear on the projected screen) and data export are both paid-only — neither is on the free Basic plan. If you are collecting anonymous questions in front of a room, moderation is not optional, which effectively pushes most live events onto a paid tier or a one-time plan.
The billing model: annual only, no monthly
This is the part that surprises people coming from a tool with a monthly option. Slido's standard paid plans are billed annually — there is no month-to-month subscription (Slido Community — all about annual plans). The upside of the annual plan is volume: you can run an unlimited number of slidos across the year, each able to stay live for a long window, so a team that presents regularly amortises the cost quickly.
Reported annual figures vary, so treat these as a guide. Across pricing listings, Engage lands around $150–210/year, Professional around $600–900/year, and Enterprise around $1,800–2,400/year. The spread comes from different sources, regions and promotions, and from Slido not publishing one fixed number per tier. The direction is consistent even if the exact figure is not: the annual commitment is the baseline, and it only pays off if you use it more than a couple of times a year.
Checked from Japan, the official pricing page displayed prices in Japanese yen, excluding VAT: annual plans Internal ¥135,000, Corporate ¥180,000 and Enterprise ¥360,000 per year (billed yearly, no monthly option), and one-time plans Private ¥30,000, Pro ¥53,000 and Premium ¥150,000 per event. Tier names, currency and amounts differ by region, which is why third-party dollar figures vary — the price Slido shows you in your own region is the one that applies.
One-time event plans: paying for a single event
If you only have one event, you do not have to subscribe for a year. Slido sells one-time event plans: a single slido that can stay live for up to 7 consecutive days, with unlimited polls, surveys, quizzes and Q&A for that event (Slido Community — all about one-time plans). The price is set by the participant tier you need rather than by features.
Reported per-event figures again vary by source: the smaller tiers are commonly cited around $80 (roughly 200 participants) and $250 (roughly 1,000 participants), rising steeply for the largest rooms (figures up to the high hundreds or more appear for 5,000-participant events). Because this scales with room size, a one-time plan is cheap for a small workshop and expensive for a big conference — and buying several one-time plans across a year can quietly cost more than a single annual subscription.
A one-time plan solves the "I only need it once" problem, but its price is tied to the participant tier, not a flat fee. A 1,000-person event on a one-time plan costs several times a 200-person one, so a large single event can approach the annual subscription price anyway. Always price your actual headcount, not the entry tier.
The free Basic plan and its real ceiling
Before paying anything, it is worth knowing exactly where the free plan stops, because for a genuinely small session it may be all you need. Basic is permanently free (it does not expire) and gives unlimited audience Q&A, but it caps you at 100 participants per event, 3 polls and 1 quiz (Slido Community — participant limits).
The two limits that most often force an upgrade are not the participant count but the missing features: question moderation and data export are both paid. A 90-person internal stand-up with a couple of polls fits comfortably; a public-facing session where you need to screen questions before projecting them, or a workshop where you must export the results afterward, does not. For the full breakdown of what the free plan includes and where each limit bites, see the Slido free plan limits explained.
Subscription vs per-event: the break-even math
The decision comes down to a simple comparison between what you would pay per event and what the annual plan costs spread across your real event count. Work it in three steps.
Be honest about how many live sessions you actually run in a year, and the largest headcount among them — the biggest room sets the tier you must buy, for both models.
Multiply the one-time event price by your number of events, and compare it to the annual subscription at the same participant tier. A few 200-person events may be cheaper per-event; many events, or one huge event, tilt toward annual.
If the annual plan sits unused for ten months, its real cost per event is high even when the sticker price looks reasonable. Factor in that a subscription is paid whether or not you use it.
For many organisers the answer is "neither fits cleanly": the annual plan is overkill for three events a year, and stacking one-time plans priced by room size gets expensive as the audience grows. That gap — a few large, occasional events — is exactly where a flat pay-per-use model comes in.
A flat pay-per-use alternative for occasional events
If your pattern is a handful of events a year rather than a weekly cadence, it is worth pricing a tool that charges by use instead of by year. ZENIN CLOUD is $70 for 7 days ($10/day), pay-per-use, credit-card only, with no contract, no sales call and no cancellation step. You buy the days you run an event and pay nothing in between — and there is no plan-based participant cap to upgrade through, so a 200-person and a 2,000-person event cost the same.
Beyond the billing shape, it is built for the room: participants join over a single QR code with no app or login, a live word cloud renders on the venue screen in real time, an AI classifier blocks inappropriate posts automatically rather than relying on manual approval, and every session exports to CSV. For occasional large events, that removes both the participant-tier upgrade and the idle annual fee at once.
This is not a blanket "cheaper than Slido" claim — if you present every week, Slido's annual plan, moderated Q&A queue and meeting integrations earn their keep. It is a better fit for one specific case: a few large, one-off events a year where a year-long subscription would mostly sit idle. If that is you, price it before you renew. See the live word cloud to picture it on your screen, or compare the model against Mentimeter's pricing.
Subscription, per-event, or neither?
If two or more of these are true, run the break-even math before committing to an annual Slido plan.
Frequently asked questions
How much does Slido cost per year?
Reported annual figures vary by source, so confirm the current numbers on Slido's pricing page. Across listings, the Engage tier lands around $150–210/year (roughly 200 participants), Professional around $600–900/year (roughly 1,000 participants), and Enterprise around $1,800–2,400/year. All paid tiers are billed annually; there is no monthly plan.
Does Slido have a monthly plan?
No. Slido does not sell a month-to-month subscription. For a paid plan you either commit to a full year, or you buy a one-time event plan for a single event. This is the detail most buyers miss when comparing Slido to tools that offer monthly billing.
Can I use Slido for just one event without subscribing?
Yes. Slido offers one-time event plans: a single slido that can stay live for up to 7 consecutive days, with unlimited polls, surveys, quizzes and Q&A. The price is set by the participant tier you need — commonly cited around $80 for smaller events and $250 for mid-sized ones, rising for the largest rooms. Running several one-time events in a year can cost more than one annual plan.
Is the free Slido plan enough for an event?
For a small internal session, often yes: the free Basic plan gives unlimited Q&A and allows up to 100 participants, with 3 polls and 1 quiz per event. It stops short on two things that matter for public-facing events — question moderation before the screen and data export are both paid-only. If you need either, you will move to a paid tier, a one-time plan, or a different tool.
Is Slido or a pay-per-use tool cheaper for occasional events?
It depends on your event count and room size. If you run many events or one very large event, Slido's annual plan can be the better value. If you run a few events a year, compare the per-event one-time price (which scales with participant tier) against a flat pay-per-use tool such as ZENIN CLOUD ($70 for 7 days, $10/day), which has no annual commitment and no plan-based participant cap.
