Is your data already exposed?
Mosca's inequality: if x + y > z, data you encrypt today will still need protecting after a quantum computer could break it.
Estimates of z vary widely. Expert surveys and agencies discuss ranges from under 10 to 30+ years, and nobody knows for sure. Try several values. Regulators' 2030–2035 targets assume it could come within roughly a decade.
