How much to save and invest to cover inflation for 40 years

A defined benefit pension is a wonderful thing, but if it isn't indexed, its buying power quietly erodes year after year. This piece takes up the question of how much a soon-to-be retiree should set aside today to make up for the slow bite of inflation across a long retirement that could stretch four decades. It walks through the present-value thinking behind that kind of estimate, and shows why even a small change in the assumed inflation rate makes such a large difference once it compounds over so many years. Just as useful is the reminder not to fall into tunnel vision: CPP and OAS are indexed, spending often tapers in the later years, and the gap looks smaller once the whole retirement picture is in view. It's a thoughtful read for anyone counting on a fixed pension.
