Ever hear the story of someone putting all their savings in a 401(k), only to face a tough road later due to limited access to funds and tax complications? How about, all their cash in their home only to be stressed of where the next bill will be paid from shortly thereafter? Unfortunately, this happens more often than you’d think. While saving diligently is a great habit, how you save can make all the difference.

The Optimal Savings Waterfall is more than just a strategy; it’s a financial blueprint. It prioritizes flexibility, minimizes lifetime taxes, and ensures you’re prepared for both the expected and the unexpected. Here’s how you can make your money work harder for you.

What is the Optimal Savings Waterfall?

The Optimal Savings Waterfall is a systematic approach to financial growth that balances tax efficiency and long-term flexibility. Rather than “putting all your eggs in one basket,” this strategy encourages diversifying where, and how, you allocate your savings.

Balancing Financial Growth with Tax Efficiency

Think of your finances as a game of chess. Each move you make now, whether it’s saving in a 401(k) or a taxable account, will impact your future. The Optimal Savings Waterfall helps you make intentional “moves” by:

• Prioritizing tax-efficient investments to minimize your lifetime tax bill.
• Retaining flexibility by ensuring you have access to funds when you need them, whether for emergencies, business opportunities, or unexpected challenges.

Why It’s Essential for Long-Term Flexibility

Picture this scenario: you’ve saved for retirement but realize most of your funds are locked into accounts that penalize early withdrawals. You’re asset-rich but cash-poor. The Optimal Savings Waterfall safeguards against these pitfalls, creating balance by addressing both mid-life needs and long-term goals.

Nerd Note: According to the Federal Reserve, 36% of adults reported they wouldn’t be able to cover a $400 emergency expense without borrowing. Strategies like this could improve that statistic significantly.

The 7 Steps to Optimizing Your Savings Waterfall

Step 1: Build Your Emergency Fund First

Before doing anything else, save 3–6 months' worth of living expenses in a highly liquid account, like a high-yield savings account. This is your safety net for the curveballs life throws your way, from job loss to medical bills.

Step 2: Max Out Employer-Sponsored Matches

If you have access to employer-sponsored plans like a 401(k) or 403(b), contribute at least enough to take full advantage of the employer match. That’s free money, and who doesn’t want that?

For example, if your employer matches $0.50 for every dollar you contribute up to 6% of your salary, contributing less than 6% means leaving money on the table.

Step 3: Address High-Interest Debt

If you’re carrying high-interest debt (above 7–8%), make tackling it a priority. Why? High interest eats into your savings faster than most investments can grow.

Nerd Note: The average American pays $1,380 per year in interest on credit card debt according to NerdWallet in 2023. That money could go toward investments or retirement savings instead!

Step 4: Leverage HSA Accounts

HSAs: With triple tax benefits (tax-free contributions, growth, and medical withdrawals), these are ideal if you have a high-deductible health plan.

With triple tax benefits (tax-free contributions, growth, and medical withdrawals) for those with a qualifying High Deductible Health plan, these are the most tax advantaged accounts out there if used correctly.

A deduction in the year of contribution is nice, but the biggest benefit comes from the account if it is invested for future medical expenses. For instance, a couple/family contributing $8,550 in 2025 paying a combined 35% in taxes will save ~$3,000 this year

Step 5: Max Out Tax-Advantaged Retirement Accounts

For high earners or those without a near term need for the additional funds, it is worthwhile considering maximizing your 401(k) or 403(b) contributions which are up to $23,500 in 2025 with a $7,500 additional contribution for those over 50. Just because you are maximizing your 401(k) match, doesn't mean you are fully leveraging it for lowering your lifetime tax bill!

Step 6: Leverage Additional Accounts (529s, etc.)

Once your debt is under control, focus on maxing out contributions to tax-advantaged accounts like 401(k)s, 403(b)s, or Roth IRAs. For 2024, the contribution limit is $23,000 for 401(k)s.

If you’ve already maxed out retirement accounts, turn to specialized accounts to save money growing for retirement. These accounts not only reduce your taxable income now but also ensure you

529 Plans: Perfect for saving for your children’s education with tax-free growth and withdrawals.

457 Plans: Additional retirement accounts for non-profits and academic institutions that can supercharge retirement savings similar to but with important distinctions from the 401(k) & 403(b).

Step 7: Strengthen Flexibility with Taxable Investment Accounts

Once all other options are maxed out, it’s time to focus on taxable accounts. These provide unmatched flexibility, allowing you to access funds without penalty and save toward mid-term goals or even early retirement.

Taxable accounts don’t have contribution limits, making them an excellent “catch-all” for savvy investors looking to stay ahead.

Many retirees wish they’d used more taxable accounts earlier in life. Why? The lack of withdrawal penalties creates a safety valve that tax-advantaged accounts just can’t provide.

Relying on a single type of account, like a traditional 401(k), can lead to unintended consequences. For example, retirees who overfund these accounts often face higher tax burdens when taking distributions.

Diversifying Across Tax Categories

Instead, aim to balance your savings across three tax categories:

1. Tax-Deferred: Contributions are tax-deductible now (e.g., 401(k)).
2. Tax-Free: After-tax contributions grow tax-free (e.g., Roth IRAs).
3. Taxable: No upfront tax benefits, but withdrawals come without penalties (e.g., brokerage accounts).

By spreading savings across these categories, you’ll reduce your lifetime tax bill and maintain flexibility.

Planning for Future Flexibility

Tax diversification isn’t just about saving money, it’s about access. Whether buying a house, starting a business, or navigating unforeseen emergencies, having accessible funds can dramatically improve financial outcomes.

Nerd Note: The concept of a diversified “tax bucket” strategy ensures you’re not caught unprepared, whether in good times or bad.

Common Mistakes to Avoid with the Savings Waterfall

Neglecting Emergency Reserves

Jumping directly into investments without building an emergency fund can derail your long-term goals during a sudden financial shock.

Over-Prioritizing Debt Payoff

While paying off debt is important, prioritizing it over employer-matching contributions is a missed opportunity for “free money.”

Ignoring Tax Implications Later in Life

Focusing exclusively on tax-deferred accounts without balancing tax-free and taxable savings can create unnecessary hurdles in the future.
