## Formula

NRR = (starting recurring revenue + expansion − contraction − churn) ÷ starting recurring revenue × 100.

- Methodology: cohort-based NRR — revenue from new customers acquired during the period is excluded.
- GRR is shown alongside so expansion can't hide churn.
- Common SaaS practice; no standards body defines it.
- NRR = (starting recurring revenue + expansion − contraction − churn) ÷ starting recurring revenue × 100.
- Inputs used: Currency (symbol only, never converted), Recurring revenue at start of period (from existing customers), Expansion (upsells, cross-sells, price increases), Lost to downgrades, Lost to cancellations.

## Inputs

- Currency (symbol only, never converted)
- Recurring revenue at start of period (from existing customers)

## Worked example: A year

$1,000,000 start, $180,000 expansion, $40,000 downgrades, $60,000 cancellations.
1. Ending = $1,080,000.
2. NRR = 108%.
