15Five true cost: the 36-month total
15Five costs $1,440 over 36 months on Engage at 10 users, billed annually, before 6 cost lines that sit outside the plan price.
What 15Five costs over 36 months
Every figure below is 15Five's own published rate, annualised and multiplied out over 36 months at 10 users. Where 15Five publishes no rate, the row says so instead of guessing.
The same plan at four team sizes
15Five charges per user, so the 36-month figure scales linearly with headcount. These are Engage totals, on annual billing, with no fees added.
Renewal sensitivity: three scenarios, not a forecast
Nobody knows what 15Five charges in 2029. The table below is arithmetic on a rate you choose, not a prediction: it compounds the year-one total forward at 0%, 5% and 10% so you can see how much of the 36-month figure is exposed to a renewal you have not negotiated yet.
Scenario arithmetic on 15Five's own published year-one figure. Uplift rates are illustrative inputs, not observed or predicted rates.
What sits outside the 15Five list price
6 lines, sorted by when in the contract lifecycle they land. Lines marked as derived are arithmetic on 15Five's own tier table rather than vendor prose.
Each line, what triggers it, and how to avoid it
Paid add-on or module
Stated on the pricing page: Manager Content add-on $49/manager/month
What triggers it. Fires on adoption, not on signature. 15Five prices the platform at $40 a month for 10 users and the pieces separately, which is why quoted comparisons between tools so rarely describe the same scope.
How to avoid it. Build the shortlist at like-for-like scope. Price 15Five with the add-ons you actually need against rivals with theirs, or the $1,440 comparison is measuring different products.
Usage and overage
Stated on the pricing page: Coaching credits $399 each
What triggers it. Usage, not people, drives this. That makes it the least predictable component of a three-year 15Five commitment and the one most worth instrumenting early.
How to avoid it. Negotiate committed-volume pricing if consumption is predictable at all. Over 36 months, a pre-committed rate beats list overage by a wide margin.
Paid add-on or module
Stated on the pricing page: Kona AI Meeting Assistant $2/employee/month
What triggers it. A separately-priced module. It stacks on top of the plan rate for as long as you keep it, and on a per-unit add-on it also scales with the 10 users basis.
How to avoid it. Review attached add-ons at each anniversary. Modules bought for one project keep billing long after the project ends.
Paid add-on or module
Stated on the pricing page: Compensation module $9-$11/user/month
What triggers it. Triggered by needing the capability, and then charged every cycle afterwards. Add-ons attach to the Engage subscription permanently, so this is a recurring line the $1,440 figure does not contain.
How to avoid it. Bundle the add-ons into the initial negotiation. They are discounted far more readily at first signature than when added in year two as a mid-term upsell.
Feature gated to a higher tier
Derived from the published tiers: Moving from Engage to Total Platform costs a further $4,320 over 36 months at 10 users, which is 4.0x the entry total.
What triggers it. Triggered by needing one feature, not by growing. This is the mechanism that moves teams off Engage: a single requirement that only exists further up the ladder, at a rate that applies to every unit you buy.
How to avoid it. List every gated capability you will plausibly need in three years, then price 15Five at that tier from the start. Comparing entry tiers you will not stay on is how a $1,440 plan becomes a much larger invoice.
Seat expansion
Derived from the published tiers: Five more users on Engage add $720 across 36 months, on top of the $1,440 above.
What triggers it. Triggered by hiring. Every figure above is priced at 10 users; this line is what each unit past that costs, and it compounds for the remainder of the term rather than the remainder of the month.
How to avoid it. Get expansion pricing fixed in the order form for the full term. Without it, seats added in month 20 are quoted at list.
How that compares across observability, monitoring, and incident response
The median observability, monitoring, and incident response tool we track charges $25 a month at its cheapest paid tier. Re-expressed on the same basis as the figure above, 10 users for 36 months, that median works out at $9,000.
15Five lands $7,560 below that figure, 84.0%, measured across 17 tracked tools. A gap either way is a question, not a verdict: cheaper often means fewer included seats or a thinner support tier, and the fee lines below are where that difference usually reappears.
What changes at enterprise scale
Everything above prices the self-serve ladder. Enterprise sits off that ladder, which means the $1,440 figure is a floor for a large deployment rather than an estimate of one.
All plans require annual billing; volume discounts negotiated for large headcounts.
Frequently asked questions
How much does 15Five cost over three years?
$1,440 on Engage at 10 users, billed annually, which is $40 a month held flat for 36 months. That figure covers the subscription only.
Does paying 15Five annually save money?
15Five publishes the same effective rate either way on Engage, so there is no prepay discount to capture. Keep the monthly option unless the vendor offers something for the commitment.
What does 15Five charge for outside the plan price?
6 lines: paid add-on or module, usage and overage, paid add-on or module, paid add-on or module and 2 more. Each one is broken down above with what triggers it and how to avoid it.
Could 15Five cost more at renewal?
Possibly, and nothing on this page predicts it. If the rate held flat the three-year total would be $1,440; at a hypothetical 10% a year it would be $1,588.80. Cap the uplift in the contract and the question stops mattering.
What does 15Five cost for a team of 25?
$3,600 over 36 months on Engage, billed annually. 15Five charges per user, so that scales directly with headcount.
