pump.fun Bundler Fees Explained: Flat, Percentage or Subscription

A bundler's headline fee tells you very little on its own. A low flat fee can be expensive if you launch small and often; a percentage that looks high can be cheap if you trade lightly. The only number worth comparing is your total cost per month at your own volume, with network costs included.

Here is how the main fee models work, what sits on top of them, and a worked example with made-up numbers so you can run the same sum for the tools you are considering.

#The three fee models

#Flat fee per launch

You pay a fixed amount each time you launch, whatever the size of the buys. Trading afterwards may be free, or may carry its own fee.

Good for: launches with large buys, where a percentage would add up. Bad for: small test launches, where a fixed fee is a big share of what you spend.

#Percentage of volume

You pay a percentage of the SOL that goes through the tool: launch buys, and often buys and sells afterwards. Cost scales with use. Some tools lower the rate for larger trades.

Good for: small launches and occasional trading. Bad for: heavy traders, unless the rate drops with size.

#Subscription

You pay a fixed amount per month or per week. Sometimes that replaces per-trade fees; sometimes it only unlocks features and per-trade fees still apply.

Good for: frequent launchers and traders, once volume is high enough. Bad for: someone who launches once and leaves the subscription running.

Plenty of tools mix these: a percentage on trades plus a subscription for extra features, or a flat launch fee plus a percentage on trades. Read which actions each fee applies to.

#Costs on top of any tool fee

These go to the network, to Jito or to pump.fun, not to the bundler. They apply whatever tool you use.

Tips and rent are small per launch but real. Our Jito tips explained post covers how to judge the tip.

#A worked example (made-up numbers)

Imagine three fictional tools:

• Tool A: 0.2 SOL flat per launch, no fee on trades.
• Tool B: 1% of SOL volume, on launch buys and on every buy and sell.
• Tool C: 1.5 SOL per month subscription, no per-trade fee.

Now three fictional users. "Volume" is launch buys plus all trades afterwards, per launch.

Monthly tool fees for each:

Three users, three different cheapest tools. The tester should pick the percentage model, the regular user the flat fee, and the heavy user the subscription. The headline rates did not decide it; the volume did.

Network costs would be added to every column equally, so they do not change the ranking. They do change the total, which matters when you are budgeting.

#How to run this for real tools

1. 1

   Write down your own numbers

   Launches per month, SOL in launch buys, and roughly how much you trade afterwards.

2. 2

   Find each fee and what it applies to

   Launch only, or every buy and sell? Is there a lower rate for larger trades?

3. 3

   Add subscriptions only if you would need them

   Count a plan if you need its features, not because it exists.

4. 4

   Add network costs once

   Tip, priority fees and rent per launch, the same for every tool.

5. 5

   Compare the monthly total

   Then weigh it against what each tool does that saves you time or failed launches.

#How DevBundler charges

DevBundler uses a percentage model: a fee on the SOL spent in launch buys, and on buys and sells from the project dashboard. The amount is shown in the confirmation before anything is sent, and larger trades can get a lower rate. We do not quote rates in blog posts because they can change; the app always shows the current figure.

Premium is an optional monthly plan paid in SOL. It adds features (more wallets per bundle, Bundle mode trading, Turbo speed, scheduled distributions, CSV export, more chart history) rather than replacing the trading fee. Free vs paid pump.fun bundlers goes through what each plan includes.
