What is a Slush Fund?

A slush fund is a pool of money set aside for a specific purpose, usually outside your main budget.

People use the term in two main ways:

  1. Everyday money talk (neutral/positive):

    • A casual “fun money” or miscellaneous pot in your budget

    • Used for things like small treats, takeout, hobbies, or unplanned expenses

  2. Business/politics (negative):

    • A secret or off-the-books fund

    • Sometimes linked to unethical or improper spending (like bribes or hidden expenses)

So context matters: in personal finance, a “slush fund” can just mean a flexible spending bucket.

In corporate or political contexts, it often has a shady meaning.

Using KOHO Essential Instead of a “Messy” Slush Fund

If you like the idea of a flexible spending bucket—but want it to be clean and transparent.

  • It has a low monthly plan fee that can be waived when you set up direct deposit or add +$1,000.

  • Use a prepaid Mastercard® for groceries, bills, subscriptions, and travel.

  • Grow your savings with a 2% interest savings rate on your entire balance.

  • Earn 1% cash back on groceries, eating & drinking, and transportation.

  • You can subscribe to Credit Building for $10/month, it's an affordable way to build your credit history.

  • Enjoy unlimited transactions and free e-transfers (never worry about fees when sending money to someone again).

Should You Have a Personal Slush Fund?

Used well, a personal slush fund can:

  • Give you permission to spend on small joys without guilt

  • Stop you from dipping into savings or emergency funds for non-essentials

  • Make your budget feel less strict and more livable

Just make sure:

  • You decide the amount upfront (e.g., $50–$200 per month)

  • You don’t let it become an excuse for constant impulse spending

  • You keep true emergency savings separate

Think of it as: “fun money with a limit,” not a bottomless pot.
