GTA 6 Bunker Profit Calculator

What the Bunker actually is

The Bunker is an underground weapons-manufacturing facility — the business most veteran players call the game’s original "money printer". You buy or steal raw supplies, your staff slowly turn them into sellable weapon stock while you do literally anything else, and you cash out whenever you feel like running a sell mission. That set-and-forget rhythm is exactly why it stays a top recommendation for players who don’t want to babysit a business.

How Bunker production works

Production runs on a supply bar. A full bar of supplies keeps your staff manufacturing for roughly two hours of real playtime, and stock builds continuously as long as you stay in an active session. You have two ways to fill it:

Buy supplies — instant, costs money, and eats roughly a fifth of your gross profit. Best if your time is worth more than the cash.
Steal supplies — free, but each run costs you 10–15 minutes. Great when you’re broke, terrible once your hourly rate is high.

The Bunker also splits its effort between manufacturing and research. Research unlocks weapon upgrades but produces no sellable stock, so if money is your goal, keep the assignment on manufacturing only.

Which upgrades are actually worth buying

An un-upgraded Bunker is genuinely slow — this is the single biggest reason new players think the business is bad. Two upgrades change everything:

Equipment upgrade — the biggest single jump in production speed. Buy this first, always.
Staff upgrade — stacks on top of equipment for another large boost.
Security upgrade — optional. It reduces raids on your stock, which matters more if you often leave large amounts sitting unsold.

Our calculator’s "fully upgraded" toggle assumes equipment and staff are both bought, which is how the Bunker is meant to be run.

Selling: solo vs crew

This is where planning matters. Small and mid-sized sales usually spawn a single delivery vehicle, which any solo player can handle comfortably. A completely full Bunker, however, can spawn several vehicles at once with one shared timer — and one person cannot drive them all. The practical solo rule: sell at roughly half stock rather than waiting for a full bar. You lose a small bulk bonus but you never fail a sale.

Should you buy the Bunker?

The Bunker is an excellent second business rather than a first one. It needs no prerequisite property, so the entry cost is honest, but it becomes strong only once upgrades are paid for. If you already own a cheap starter business and want income that accumulates while you play other content, this is the natural next purchase. If you’re still on your very first million, a cheaper mobile lab pays itself back faster.

💡 Best practice: buy supplies, then go run heists or races. Come back when the stock bar is high, sell at partial stock, and repeat. You’re effectively earning two incomes at once.

Common Bunker mistakes

Running it un-upgraded and concluding the business is weak — upgrades roughly double output.
Leaving it on research while expecting sellable stock to appear.
Waiting for a full bar as a solo player, then failing the multi-vehicle sale and losing the lot.
Forgetting daily upkeep — staff and running fees are charged whether or not you sell, which is why our calculator shows net rather than gross.

How the Bunker works in GTA Online today

The estimate here mirrors the confirmed Gunrunning business in GTA Online, one of the most reliable earners in the whole game. A Bunker turns supplies into stock passively while you do other things, and with the Equipment and Staff upgrades a full stock sells for around $1,050,000 in a full public session. Two details make it special, and our calculator accounts for both: its production runs in the background so it pairs perfectly with active content, and its research track separately unlocks Mk II weapon upgrades and weaponised vehicles — a genuine reason to own one even beyond the sale income. Supplies remain a real cost, and that is what we subtract before showing your net figure.

Frequently asked questions

Is the Bunker a good business in GTA 6?

It is modelled as one of the best passive earners in the game, the same role it plays in GTA Online. Because it produces stock in the background, it is ideal to run underneath active money methods so you earn from two sources at once.

Should I buy supplies for the Bunker or steal them?

Buying supplies is the standard choice for players who value their time — it lets the Bunker earn genuinely passively. Stealing is free but eats the playtime you could spend on higher-value active content. The calculator shows net profit after paid supplies.

Is Bunker research worth doing?

If you want Mk II weapons or weaponised vehicles, yes — research is the only way to unlock them. If you only care about sale income, research is optional and slows stock production while it runs.
