Definition
Retention is the percentage of customers (or revenue) that remain active after a defined period — the inverse of churn — and the foundation of compounding growth in subscription and repeat-purchase businesses.
Acquisition gets the headlines; retention pays the bills. A business with 90% annual retention compounds growth as new customers stack on top of existing ones; a business with 70% retention has to acquire furiously just to stand still. The math is brutal and most founders learn it too late.
Net revenue retention (NRR) above 100% is the gold standard — it means existing customers spend more this year than last, so the business grows without acquiring anyone new. NRR above 120% is the signature of category-leading SaaS.
Origin
Direct-mail and subscription businesses have tracked retention since the early 20th century. The modern SaaS-flavoured framing (cohort retention curves, NRR, expansion) came together in the 2010s through metrics writing by Skok, Wilson, and Tunguz.
How it works
- Define a retained customer — active at end of period, paying, or both.
- Pick a cohort (customers who started in month X).
- Plot the cohort's size at month 1, 3, 6, 12 — the retention curve.
- Compare cohorts to spot improvements or regressions over time.
- Build a retention curve per acquisition channel and per plan tier.
When to use it
Use when
- On every subscription or repeat-purchase business.
- Cohort-by-cohort to see whether changes are working.
- By segment — enterprise vs SMB curves usually look very different.
Skip when
- On a one-time-purchase business with no repeat dynamics.
- Without cohort segmentation. Aggregate retention hides which cohorts improved.
Key metrics
- 1-month, 3-month, 6-month, 12-month retention rates.
- Net revenue retention (NRR) including expansion.
- Gross revenue retention (excluding expansion).
- Cohort 'smile curve' — does retention stabilise or keep declining?
Examples
- 12-month logo retention sits at 87% — well above the 75% benchmark for our segment.
- Net revenue retention hit 118% — every $1 of last year's revenue is now $1.18.
- The cohort curve flattens at month 4, which means we have product-market fit.
In practice at Makreate
Makreate's email and CRM work is often retention work in disguise. A recent DTC client was acquiring well but losing 60% of customers after the first order. We built a 5-email post-purchase lifecycle that solved the most common product confusion at days 3, 7, 14 and 30. Repeat-purchase rate climbed from 22% to 38% in six months — and that doubled their effective LTV without changing acquisition spend by a dollar.
Email Outreach Automation →Common mistakes
- Tracking only month-1 retention. The shape of the curve at month 6 and 12 matters more.
- Confusing engagement retention (logged in) with revenue retention (paid).
- Ignoring expansion. Expansion is the difference between a 95% NRR and a 125% NRR.
- Spending on retention before product-market fit. Bad product can't be retained.
Frequently asked
What's a good retention rate?
Enterprise SaaS: 90%+ logo retention annually, 110%+ NRR. SMB SaaS: 75%+ logo retention. Consumer subscription: month-3 retention is the canonical benchmark and varies widely by category.
Retention vs engagement?
Retention = still paying. Engagement = still using. They diverge — engaged users sometimes don't pay (free tier) and paying users sometimes don't use (deadweight). Both matter, differently.
How do I improve retention?
Onboarding (first 30 days carry most of the loss), customer success at high tiers, product fixes for predictable friction, and lifecycle communication that reminds customers of value.
