Which Proton plan should you buy?
Quick answer: count the people first, then the products, then the storage. One person who only wants encrypted mail should look at Mail Plus. One person who wants the whole suite should look at Unlimited. Two people share Duo, and a household of up to six shares Family. The calculator below picks the cheapest plan that fits.

This picker compares one Proton plan at a time. Stacking separate individual plans, such as Mail Plus next to Drive Plus, is out of scope here.
Is Proton Unlimited worth it?
Proton Unlimited is €119.88 a year for one person. Buying Mail Plus and Drive Plus separately costs €95.76 a year, so Unlimited is €24.12 more. For that difference you move from 200 GB to 500 GB and add Calendar, VPN, Pass and Wallet. Skip it if you will not use those.
Is Proton Duo cheaper than two Unlimited plans?
Two Unlimited plans cost €239.76 a year and give each person 500 GB. Proton Duo is €179.88 a year for 2 people with 2 TB pooled between them, so Duo costs €59.88 less. The trade-off is one shared pool instead of two fixed allowances.
Who should pick Proton Family?
Proton Family is €287.88 a year for up to 6 people and 3 TB of shared storage. Filled to 6 seats that works out at €47.98 per person per year, against €89.94 on Duo at 2 seats. It is the only suite plan we captured that covers more than 2 people, so a couple pays less per person on Duo.
How the picker chooses
Every candidate is a Proton plan in our committed dataset, in the currency and billing period you selected. A plan fits when it covers at least as many people as you asked for, includes every product you asked for, and bundles at least as much storage as you asked for. The cheapest fitting plan per year wins, and the sentences under it quote the same numbers the dataset holds.
Storage is compared as Proton states it for the whole plan, not divided per person, because Duo and Family pool one allowance across the accounts. Prices are never converted between currencies. Plans Proton sells but that we could not capture a price for, such as VPN Plus, are named as not captured rather than estimated. Only single plans are compared here, so stacking two individual subscriptions is left to you.
