How Much Should You Actually Invest as a First-Time Angel?

Ah, I remember my first angel investment over a decade ago. It was into a startup I was the CMO for, and I was excited! So excited I wrote out a cheque that was way too big, still one of the biggest ones I've written. And it returned a mere 17% (not an extra 17%, I'm talking I only got 17% of that money back). Ouch.

This happens a lot, but it's entirely avoidable. One of the first things I talk about with new angels is to think early about this question: how much should I be putting into this?

It deserves a real answer - not a vague "it depends" or deciding on an investment-by-investment basis.

Here's a three-part exercise to help you think it through.

Step 1: The Gut Check

Before any math, one question:

If every single company you invested in went to zero - because statistically, many will (there's that Power Law at work) - would you be okay? Financially and emotionally?

If the number you're imagining makes your stomach drop, it's too high. Angel investing is a long game, and the only money that belongs here is money you can truly afford to lose. Adjust until you can answer yes (and remember, thinking about losing any money is not fun, but the goal here is to find the sweet spot between "I definitely want to get into this game" and "I need to be smart about my allocations").

Step 2: The Angel Budget Calculator

Some quick math to run through:

Start with your investable net worth - liquid assets, excluding your home, locked retirement accounts, etc
Take 5-10% - that's the general guideline for high-risk, illiquid alternatives (experienced investors can often have 10-15%, but this is a great starting point)
That's in the range of your angel budget

Example: $500K investable assets × 10% = $50K angel budget

Step 3: Sizing Your Cheques

Diversification is everything in angel investing, and conventional wisdom says you need at least 10 deals to have a real chance at returns. This is the "shots on goal" mentality.

Divide your initial angel budget by 10 or more to get your per-deal cheque size
Ask yourself: does that number feel meaningful to you and manageable?

Example: Initial budget of $50K ÷ 10 deals = $5K per cheque

Note: This is a good starting point to think about your investments as a portfolio. You could decide you want to do 20 investments, or you could find at the end of the first year your budget can increase, or you could look at this as a Y1 benchmark.

Step 4: Annualize It

Angel investing is a multi-year commitment. Take your total budget and spread it out over a timeline that makes sense to you based on what you know or don't know about your future available investable capital.

Let's say you've determined that $50K is your budget for the next three years.

Divide your angel budget by 3 to get a rough annual number
Think of it like any other line item: "I'm committing $15-17K per year to angel investing"

Example: $50K budget ÷ 3 years = ~$17K/year, or roughly 3 deals at $5K each

A few things to keep in mind:

You don't have to allocate everything at once, a lot of angels start with 2-3 deals in year one while learning
Smaller cheques are completely normal, especially through angel groups or SPVs where you can participate for as little as $1K-$5K
This budget is fluid, revisit it annually as your portfolio and confidence grow, or as things change in your capital position

The goal of this process isn't to get to a perfect number. It's to set intention for your angel process so you can go in with clearer parameters and create a strong, smart foundation as you get into the game.
