Monthly cost = plan price (monthly, or the per-month equivalent of annual billing) + overage beyond the allowance, before tax, one user. Allowances stay in each vendor's own unit; minutes and characters are converted only where the vendor states a rate (ElevenLabs and Murf: about 1,000 characters a minute), so vendors without a stated rate are missing from rankings in the other unit. A plan whose allowance is exceeded and that states no overage price is treated as not fitting. Plans that do not state commercial use are left out of the commercial tables. monthly price = no annual price is published, so the monthly price is used. Ties are broken by name. Affiliate status is never used.
