At full price, all The Sims 4 packs together are roughly $1,500 USD today, depending on whether you count the base game and which bundle discounts or regional prices apply.

Breakdown

Pack type| Current count| Price each| Total
---|---|---|---
Expansion Packs| 20| $39.99| $799.80 8
Game Packs| 12| $19.99| $239.88 8
Stuff Packs| 20| $9.99| $199.80 8
Kits| 53| $4.99| $264.48 8

That adds up to $1,507.95 for every current piece of Sims 4 content at full price, with the free base game included in the total.

Extra context

A slightly older breakdown from another source put the full DLC total at about $1,064.45 before later content releases, which shows how fast the total climbs as more packs get added. Another recent summary estimated the full price at about $1,200 to $1,300 , but that was based on a different pack count and older assumptions.

Bottom line

If you mean everything available right now , the safest estimate is about $1.5k before sales. On sale, the total can drop a lot, sometimes by hundreds of dollars.
