Payback Period on a Pitch Deck: Whose Money, Paid Back

How founders show CAC payback, customer payback and location payback on a pitch deck: what is being paid back, from revenue or gross profit.

How to Show a Payback Period on Your Pitch Deck, and Make It Reproducible

Fifteen slides from real pitch decks that state a payback period. For each, we record what is being paid back, what pays it back, whether the figure is measured or a target, and whether the slide's own numbers reproduce it.

TL;DR

A payback period is how long it takes for money spent to come back. On pitch decks the phrase covers at least three different things: CAC payback (how many months of a customer's gross profit it takes to recover what the company spent acquiring them), customer payback (how quickly the product pays for itself for the buyer) and unit payback (how quickly a new location, kitchen or machine recovers its set-up cost). A payback figure earns trust when the slide says which of these it is, whether it is calculated from revenue or gross profit, which customers or period it is measured on, and gives the inputs so a reader can reproduce it.

In this set, Evvnt gives every input: CAC of $177 and gross profit of $58.98 per month give 3.0 months, matching its stated "3 months" (our calculation). Kredivo and Nas.com show payback as a curve by customer cohort. Rippling breaks its 17-month figure into cross-sell and marginal versions with footnoted definitions. Several other slides state a payback with no inputs, and Arya's "Payback under 8 months" does not say what is being paid back.

Key Takeaways

  • Say what is being paid back. Mero and Viso describe the customer's payback on the product; Evvnt and Kredivo describe the company's payback on acquisition spend.
  • Use gross profit, not revenue. Evvnt's 3-month CAC payback uses its $58.98 monthly gross profit, and the arithmetic reproduces (our calculation).
  • Show the inputs. iConsumer gives a cash CAC under $20 and first-year cash of over $50, but its lifetime value is written as "?".
  • Label targets. OneScreen shows "Payback Period Target = 90 Days" on one slide and "Payback Period: 78 Days" on the next, keeping the two apart.
  • Show cohorts. Nas.com's chart shows its January cohort taking about ten months to reach 100% return, while later cohorts pass it in one or two months.
  • Define the blend. Rippling separates 17-month blended, 10-month cross-sell and 8-month marginal CAC payback, each with a footnote defining it.

Write your payback line

Fill in what you know. Leave a field blank rather than guess, and label any target as a target.

  1. Type. CAC payback, customer payback or unit payback?
  2. Cost. What is in CAC (or the unit investment)? Which channels and staff costs?
  3. Return. Monthly gross profit per customer (or per unit), and the margin used.
  4. Group. Which cohort or period is it measured on, and how many customers?
  5. Blend. If you quote a subset, what is the blended figure?
  6. Status. Measured, or a target?

Copyable framework: CAC payback [n] months = $[CAC] (all sales and marketing, [period]) ÷ $[gross profit]/month per customer ([margin]% margin), measured on customers acquired [period] ([n] customers). Paid channels: [n] months; referrals: [n] months.

Illustrative example 1 — written by us

Before: Payback under 6 months.

After: CAC payback 5.2 months = $410 CAC (all sales and marketing, H1 2024) ÷ $79/month gross profit per customer (72% margin), measured on 1,140 customers acquired Jan–Jun 2024. Paid search: 8.1 months; referrals: 1.9 months.

What improved: Placeholder figures showing the format: type, inputs, cohort and channel split make the payback reproducible.

Three different paybacks

CAC payback is the one investors usually mean. It divides the cost of acquiring a customer by the gross profit that customer produces each month. A 12-month CAC payback means a company needs a year of a customer's gross profit before the acquisition spend is recovered; if customers leave sooner, the company loses money on them.

Customer payback is a sales argument: the buyer's savings or extra revenue cover the price of the product within a period. Mero's summary slide says it provides "payback to customers in just 3 months"; Viso claims "695% ROI in 3 years, 3 months payback". These are claims about the buyer's economics, not the startup's, and belong on the value-proposition or case-study slide with evidence from a named customer.

Unit payback applies to businesses that open physical units. WeWork's page 18 compares a "22 month payback" for a building on market terms with a "7 month payback" for an "asset light" deal where the landlord pays more of the build-out; Muncher states "10 to 15 months payback" on a kitchen. The unit is the location, and the cost being recovered is the investment in it.

All three are useful. The problem arises when a slide says "payback" without saying which, as Arya's page 11 does: "Payback under 8 months" sits between "80% of members are millennial moms" and "Over 80% 6-month retention", and a reader has to guess that it means CAC payback.

Revenue or gross profit

CAC payback calculated from revenue flatters the figure by the gross margin. A company with 50% margins and a CAC equal to three months of revenue has a six-month payback on gross profit, not three.

Evvnt's page 10 is the clearest example of doing it properly, and also shows how easy it is to mix the two. It lists "Cost per lead $4.78", "Conversion rate to sale 2.7%", "CAC $177", "Average value per customer $884.68 per annum", "Gross profit (80%) per customer $58.98 per month", "Average contract length 2 Years", "Customer lifetime value $1,769.36", "LTV:CAC ratio 10" and "CAC Payback 3 months".

Our calculations: $4.78 ÷ 2.7% is $177, matching the stated CAC. $884.68 ÷ 12 × 80% is $58.98, matching the monthly gross profit. $177 ÷ $58.98 is 3.0 months, matching the payback, which is calculated on gross profit. The lifetime value, however, is $884.68 × 2 years = $1,769.36, which is revenue, not gross profit; on gross profit it would be $58.98 × 24 = $1,415.52, and the LTV:CAC ratio about 8.0 rather than 10. The slide uses gross profit for one figure and revenue for the other without saying so.

Kredivo's page 31 separates the two explicitly: "Lifetime Revenue" of 263 less "Lifetime Costs" of 144 gives a "Lifetime Value" of 119, against a "CAC" of 10.5. 119 ÷ 10.5 is 11.3 (our calculation), which matches both the "~11x" callout and the curve's final point of 11.3 at month 72.

Measured on whom, and when

A payback period changes with the group of customers it is measured on. Customers acquired through referrals may pay back in weeks; customers from paid ads may take a year. An average hides that, and so does a figure from a single good month.

Kredivo footnotes its chart: "LTV / CAC and CAC payback are based on January 2019 customer cohort which is representative of a typical cohort", with CAC "Based on 2019 average CAC". The chart marks the payback period at about 3.5 months, consistent with the "~3-4 Months" headline. Naming the cohort lets a reader ask the obvious follow-up question: what did other cohorts look like?

Nas.com answers that question on the slide. Its page 21, titled "Our CAC payback has improved to <2 months", plots percentage return by month for monthly cohorts from January to September against a dashed line at 100%. By our reading of the chart, the January cohort reaches 100% at about month ten, the February cohort had not reached it by month seven, and the most recent cohorts start above 100% in their first month. The headline is true of the recent cohorts; the chart shows the reader it is a recent improvement, not the history.

Mixpanel's page 8 lists sales KPIs with most figures blacked out in the public copy, ending with "Sales payback rate is around 6 months; we will get this down in 2015". It gives no cohort or definition, but it is candid about the direction of travel.

Targets and actuals

OneScreen shows how to keep a target and an actual apart. Its page 13, headed "Targets", lists "90 Day Net ARPU = $10k", "CAC = $10k" and "Payback Period Target = 90 Days"; by construction, if a customer's first 90 days of net revenue equals the cost of acquiring them, the payback is 90 days. Its page 14, headed "Traction", reports "Payback Period: 78 Days" beside a quote from a customer and a probability-adjusted revenue forecast.

The pairing is honest about which figure is which. What the slides do not say is whether the 78 days uses the same net ARPU definition as the target, or on how many customers it was measured. The target also uses revenue ("Net ARPU") rather than gross profit; for a marketplace, net revenue may already be close to gross profit, but the slide does not say.

iConsumer's page 14 is headed "Profitable Member Acquisition" and states a cash CAC of less than $20, payback in less than 60 days ("Initial cash investment recouped" within that time) and first-year cash generated of more than $50. Its last line reads "CLV (Customer Lifetime Value): ? (Since June 2018)". Leaving the lifetime value as a question mark rather than inventing one is honest, and the slide gives a reason: the company has not had customers long enough to know.

Blended, cross-sell and marginal payback

Rippling's page 14, from a later-stage memo-style deck, is the most detailed treatment in this set. It cites benchmarks from Meritech Capital: "The average public SaaS company has a 28-month CAC payback period and a 10% operating margin as of March 2024", and plots CAC payback against operating margin for a list of public software companies, reporting an R-squared of 0.65.

It then gives three figures for itself: "Rippling currently has 17-month CAC paybacks", "Rippling's CAC payback period for cross-sell is just 10 months", and "if you only burden cross-sell CAC with our direct, marginal costs for cross-sell (and exclude its pro-rata share of underlying marketing costs), the CAC payback is only 8 months". Each figure has a footnote saying what costs are included and which period (FY23, Feb '23 to Jan '24) it covers, and the footnotes note that the internal figures are "under review and subject to change".

The lesson for earlier-stage decks is the structure, not the length. If you quote a better payback for a subset of customers or a narrower cost base, show the blended figure beside it and state what was excluded.

Payback on the supply side and on physical units

Scale AI's page 28, "Supply Acquisition", applies payback to recruiting the people who label data rather than to customers: labelers recruited "through digital ads, self-sign-ups" at "CAC: $1.50" with "Payback: <2 days", and QA staff "primarily recruited via referrals" at "CAC: $175" with "Payback: 2 weeks". The slide does not say what pays the cost back (presumably the margin on work those people complete), but it applies the concept consistently to both channels.

WeWork's page 18 compares two deal types. "Market terms": "Landlord pays 50% of CapEx", "Market Rent", "No Profit Share", "40% Unit EBITDA", "22 month payback". "Asset light": "Landlord pays 75% of CapEx", "At or below Market Rent", "25-50% Profit Share", "32% Unit EBITDA", "7 month payback". The comparison shows the trade: a lower margin but a much faster payback because WeWork puts in less of its own capital.

Muncher's page 19 gives "USD $20 K to $40 K Investment in equipment", "Up to USD $50 K Revenue per Kitchen", "15% to 20% Ebitda Margin" and "10 to 15 months payback". Our calculation shows why the revenue period matters: if $50K is monthly revenue, 17.5% EBITDA is about $8,750 a month and a $40K investment pays back in under five months; if it is annual, the same investment takes more than four years. Neither reading gives 10 to 15 months, and the slide does not say which period the revenue covers.

How to build your payback line

Write the formula on the slide: CAC ÷ monthly gross profit per customer = months. Give both inputs and say where they come from: which channels are in CAC (paid only, or all sales and marketing including salaries), and what margin was used. Name the group of customers it was measured on and the period.

If payback has improved, show it by cohort as Nas.com does, or give the old and new figures with dates. If you quote a subset (a cheap channel, cross-sell, a narrower cost base), give the blended figure beside it. Keep targets labelled as targets.

Keep customer payback and unit payback on the slides where they belong, and make them reproducible in the same way: price paid, savings or revenue per month, and whose figures they are. A customer payback claim is strongest when it comes from a named customer's own numbers.

Common mistakes

Diagnostic checklist

  • The type of payback is named.
  • CAC (or unit investment) and monthly gross profit are on the slide.
  • The cohort or period is stated.
  • Blended payback appears beside any subset.
  • Targets are labelled as targets.
  • The stated figure reproduces from the slide's own numbers.

Frequently asked questions

How do I calculate CAC payback for a pitch deck?

Divide the cost of acquiring a customer by the monthly gross profit that customer produces. Evvnt's $177 CAC and $58.98 monthly gross profit give 3.0 months, matching its stated 3 months (our calculation). Use gross profit, not revenue, and say which costs are in CAC.

What is a good CAC payback period?

It depends on how long customers stay and on the business. Rippling cites Meritech Capital's figure of 28 months for the average public SaaS company as of March 2024; the early-stage slides here state from under 2 months to 8 months. Show your own figure with its inputs and cohort rather than a benchmark.

Is customer payback the same as CAC payback?

No. Customer payback (Mero's "payback to customers in just 3 months") is how quickly the product pays for itself for the buyer. CAC payback is how quickly you recover what you spent to win that buyer. Put each on its own slide and name it.

Should I show payback by cohort?

Yes, if you have the data. Nas.com's cohort chart shows the improvement from about ten months for its January cohort to under two months for recent ones, which a single figure would hide.
