True cost calculator
The advertised price is the intro rate. This tool shows what the same subscription actually costs in the first 3 years: each provider's real first-term bill (as documented), then the whole renewal charges that land inside the window - the numbers the affiliate pages leave out. Providers without a published renewal price stay "unknown"; a missing number is information, a guessed one is a lie.
Calculation: the bills that actually land within 36 months - the first-term charge, then each whole renewal charge while its cycle starts inside the window (renewals are never pro-rated; a cycle reaching past month 36 is noted as coverage). Providers billing in another currency show what they actually bill. A renewal price only disclosed per year is compared as its monthly equivalent. All math runs locally.
