Of the existing base. Be pessimistic and it still usually pays.

The arithmetic nobody runs before arguing

A rise of r survives churn of up to r over one plus r before MRR falls: 9.09 per cent for a 10 per cent rise. Most SaaS price rises cause far less, which is why the fear is usually more expensive than the churn.

Grandfathering the existing base delays the benefit but not the anger; migrating everyone with notice collects it. The honest middle: migrate with a long notice period and an annual-billing escape hatch.

The demo: 10 per cent on 200 accounts at £200, losing 3 per cent of them, is £42,680 of MRR against £40,000, a 6.7 per cent gain that compounds through every later month.
