What should I do with a large amount of cash?
By Adam Kasick | Wealth Advisor | Updated September 2026
If you've suddenly accumulated a large amount of cash, the first question isn't where to invest it. It's what the money needs to accomplish and when you may need it.
Here's how I'd think about it.
Before jumping to a product or transaction, I want to understand what changed, what this money needs to do and which decisions actually deserve attention now.
What could change the answer?
- How much needs to remain liquid?
- Are taxes or other obligations still outstanding?
- Is there a major purchase, business opportunity or transition ahead?
- How much of this money is truly long-term?
Let's make this real.
Hypothetical example. For illustrative purposes only.
Imagine someone has done a great job building wealth but a major part of the financial picture no longer has a clearly defined job. The answer isn't automatically to invest, sell or move it. The first step is understanding the purpose, timing and tradeoffs. Once those are clear, the available choices become much easier to evaluate.
Here's what I'd want to know about you.
- What do you want this money to accomplish?
- When might you need it?
- What else do you own?
- What are you most worried about getting wrong?
- If we improved this part of your financial life, what would that allow you to do?
Cash can have an important job: buying you time. The goal isn't to rush it into an investment. It's to decide what each part of the money needs to do next.
