Money makes Kairos go ’round, and even though this planet’s been cut off from galactic civilization, cold hard cash is still king. Whether you’re eyeing that shiny new weapon in Marcus’s vending machine or stocking up on ammo for your next Vault raid, you’re going to need serious funds to fuel your Vault Hunter lifestyle.

The good news? Making money in Borderlands 4 is actually pretty straightforward once you know the tricks. The bad news? It disappears just as quickly if you’re not smart about it. Let me break down the most efficient cash farming methods that’ll keep your wallet fat and your enemies dead.

The Encore Machine Money Loop: Your New Best Friend

Here’s the game-changer that most players overlook: Encore machines are basically money printers in disguise. These magical devices let you instantly reset boss fights and major encounters, and while they do cost some cash upfront, the return on investment is absolutely insane.

Here’s how the loop works:

• Fight a boss or complete a Ripper Drill Site encounter
• Use the nearby Encore machine to reset the fight (costs a small fee)
• Repeat the encounter and collect all the loot
• Sell everything valuable at the vending machines right next to the Encore machine
• Rinse and repeat until you’re swimming in cash

Pro Tip: You’ll typically break even just by selling a single purple-rarity weapon. Everything else is pure profit. I’ve personally turned 10,000 cash into over 100,000 in about an hour using this method.

The Best Cash Farming Locations

Not all encounters are created equal when it comes to cash farming. Here are the spots that’ll give you the biggest bang for your buck:

Top-Tier Money Makers

Sidney Pointylegs (Prospects Drill Site, Fadefields)

• Drops The Swarm legendary grenade
• Consistent purple weapon drops
• Quick encounter, great for rapid farming

Bramblesong (Stoneblood Forest Augur Mine, Terminus Range)

• Drops the Convergence legendary shotgun
• High-value loot pool
• Perfect for players who want combat variety

Other Solid Options

• Main story bosses – Always reliable for decent loot
• Vault bosses (all three optional ones) – Longer fights but premium rewards
• Any Ripper Drill Site encounter – Consistent purple drops

Why Sidney and Bramblesong Are Cash Farming Goldmines

These two aren’t just great for money – they’re dropping gear that’ll make your future farming runs even easier. The Swarm grenade and Convergence shotgun are absolute beasts for single-target damage, which means faster boss kills and more efficient farming loops.

The Convergence shotgun is particularly nasty – it’s basically a delete button for anything standing in front of you. Pair it with Vex’s Kinetic attunement builds for some truly ridiculous damage numbers.

Smart Loot Management for Maximum Profit

Here’s where a lot of players mess up: they either hoard everything or sell the wrong stuff. Follow these guidelines:

• Always sell purple weapons first – They give the best cash-to-inventory-slot ratio
• Keep one copy of any legendary you find – You might need it later
• Sell blue and green gear in bulk – Small profits add up quickly
• Don’t sleep on class mods and shields – Purple variants sell for serious money

Passive Money Making: Bounty Boards

While you’re progressing through the campaign, don’t ignore those bounty boards in safe zones. The contracts aren’t just busy work – they’re passive income generators that complement your main story progression perfectly.

Pick up 3-4 contracts before heading into a new area, complete them naturally as you play, then cash in for easy money without any extra farming time. It’s like getting paid to play the game normally.

Advanced Money Tips

Stack Your Farming Sessions: Don’t just farm one boss – create a route. Hit Sidney, then Bramblesong, then maybe a Vault boss. This keeps the gameplay fresh and maximizes your time investment.

Coordinate with Builds: If you’re running a melee-focused Amon build, stick to bosses that favor close combat. Playing to your strengths means faster kills and better profit margins.

Use Golden Keys Strategically: Don’t waste them early game. Save them for when you need specific gear types to optimize your farming builds.

The Bottom Line

Cash farming in Borderlands 4 isn’t rocket science, but it does require a bit of strategy. The Encore machine loop is your bread and butter, Sidney and Bramblesong are your best friends, and smart loot management will keep you profitable.

Remember: the goal isn’t just to make money – it’s to make money efficiently while getting stronger gear that makes future farming even easier. Master this cycle, and you’ll never worry about cash again.
