## Cohort Vintage Matrix

The cohort table visualizes revenue retention by month of sign-up:

| Cohort       | Initial MRR | Month 1 | Month 2 | Month 3 | Month 6 | Month 12 |
| :----------- | :---------- | :------ | :------ | :------ | :------ | :------- |
| **Jan 2026** | \$12,400    | 100%    | 104.2%  | 108.5%  | 114.1%  | 118.4%   |
| **Feb 2026** | \$14,800    | 100%    | 102.8%  | 106.1%  | 111.0%  | --       |
| **Mar 2026** | \$18,250    | 100%    | 105.4%  | 109.2%  | --      | --       |
| **Apr 2026** | \$21,100    | 100%    | 103.9%  | --      | --      | --       |

### NRR Calculation Formula

$\text{NRR} = \frac{\text{Beginning MRR} + \text{Expansion MRR} - \text{Contraction MRR} - \text{Churn MRR}}{\text{Beginning MRR}} \times 100\%$

<Tip>
  An NRR above 100% signifies net negative churn, meaning existing customer expansions outpace cancellations.
