Dollar Retention

Dollar retention is a general term for metrics that measure how much recurring revenue is preserved and grown from an existing customer cohort over time. It encompasses both Gross Dollar Retention (GDR/GRR) and Net Dollar Retention (NDR/NRR). The "dollar" framing emphasizes that these metrics track revenue, not customer count — a distinction that matters when account values vary significantly.

formula.sh

Net Dollar Retention = (Beginning MRR + Expansion − Contraction − Churn) / Beginning MRR × 100

> Beginning MRR — existing customer revenue at period start
> Expansion — upgrades, seat additions, usage overages from existing accounts
> Contraction — revenue lost to downgrades from existing accounts
> Churn — revenue fully lost from cancellations

example

Cohort of customers from Jan 2023 generated $500K MRR at start of Jan 2024. After churn (-$30K), contraction (-$20K), and expansion (+$80K).

($500K + $80K − $20K − $30K) / $500K × 100

→ 106% net dollar retention — this cohort now generates $530K MRR, a 6% increase without any new customers.

why it matters

Dollar retention is how SaaS investors measure the quality of your revenue, not just the quantity. High dollar retention proves your customers receive compounding value from your product and are willing to pay more over time. Low dollar retention means your revenue erodes unless you constantly replace it with new sales.

The "dollar" framing matters because it weights every calculation by revenue value. Losing ten $100/month customers is the same dollar impact as losing one $1,000/month customer — but the strategic implications are very different. Dollar retention captures this accurately while customer count metrics miss it.

For cohort analysis, plot dollar retention curves at 3, 6, 12, and 24 months for each acquisition quarter. Improving curves over time prove that your product, onboarding, and success motion are getting better. Flat or declining curves indicate structural problems.

common mistakes

✗Using "dollar retention" interchangeably with NRR without specifying whether you mean gross or net — the two are materially different.

✗Calculating dollar retention including new customers acquired during the period, which inflates the apparent retention.

✗Not building cohort-level dollar retention curves — aggregate dollar retention hides deterioration in newer cohorts.

pro tips

✓Build a dollar retention waterfall chart: show beginning MRR, then subtract churn, subtract contraction, add expansion, to arrive at ending MRR from the cohort.

✓Use gross dollar retention (GDR) for underwriting revenue forecasts and net dollar retention (NDR) for investor storytelling.

✓Track dollar retention by customer segment, pricing tier, and acquisition channel to identify which segments retain best.

the mrrsucks take

Dollar retention is the market telling you whether your product is worth more or less to customers over time. If it's declining, the market has made its verdict — you're just slow to hear it.

faq

Is dollar retention the same as NRR?+

Net Dollar Retention (NDR) and Net Revenue Retention (NRR) are the same metric expressed with different terminology. "Dollar retention" is a broader term that covers both gross (GDR/GRR) and net (NDR/NRR) variants.

How is dollar retention used in SaaS valuations?+

High NDR (120%+) justifies higher revenue multiples because future revenue from existing customers is more predictable and self-compounding. Bankers and investors will apply a premium multiple to revenue from cohorts with demonstrated strong dollar retention curves.
