What if you can't?

1 in 4 physicians will experience a disability during their career. Without coverage, the financial freedom number you just calculated becomes impossible.

Every doctor deserves the financial freedom to practice medicine on your terms — when, where, how, and as much (or as little) as you want.

Before you plug in numbers, it's important to understand the variables so you get an accurate result. Here's what you need to know:

Understanding the Variables
🏠
Annual Spending

The entire calculator is driven by your spending. The less you need to spend, the less you'll need to save. Don't let someone tell you that you need more because you make a higher income. It has nothing to do with that — it has everything to do with your annual spending.

How to find your number: Look at your last three months of spending (credit cards, bank statements, etc.) and multiply out to get your annual number. This is what you'd need to retire now. If you're thinking further ahead, subtract expenses you won't have in retirement (e.g. kids' college savings, your mortgage). That gives you what your annual spending will be at the age you want to be financially independent.
📈
Anticipated Compounding Interest

I always use 2–3% less than I actually expect, which allows the calculations to account for roughly 2% annual inflation.

Example: If you expect 8% returns, put 5–6% in the calculator. This gives you a more realistic, inflation-adjusted result.
🎯
Safe Withdrawal Rate (SWR)

The SWR answers the question: "What percentage of my portfolio will I take out each year to live on in retirement?" Classically, this number was 4% (the famous "4% Rule"), but recent studies suggest you may be able to take closer to 4.7%.

So you might go with a more conservative 4%, or choose something closer to 5% based on newer research. Here's a chart showing how safe withdrawal rates change based on your planning horizon:
