When is it worth paying for financial advice?

Paying for financial advice is worth it when the decision in front of you is worth more than the advice costs. That bar is lower than most people think. A one-time plan from a fee-only planner costs a median $2,000, and a single choice like when to claim Social Security can be worth more than that every year for the rest of your life. Ongoing advice is a different test: it has to earn its fee again every year.

Here’s how to run the math on your own situation.

Start with the price of the advice

Advice comes in sizes, and the cheapest size that covers your problem is usually the right one.

The hourly row is five hours at the median $300; the percentage rows apply the median 1% rate to two balances. Those are the costs you’re weighing the advice against.

Notice the shape. Hourly and one-time prices don’t move with your balance. A percentage fee does, so the bar for “worth it” rises as your savings grow. Our guide to whether a 1% fee is too much works through that in dollars.

Then put a number on the decision

Write down the decision you’re facing and what a wrong answer would cost. You don’t need precision. You need to know whether the stakes are in the hundreds, the thousands or the hundreds of thousands.

Social Security timing. For anyone born in 1960 or later, claiming at 62 pays 70% of the full benefit and waiting to 70 pays 124%, for life. On a full benefit of $2,000 a month, that’s $1,400 at 62 against $2,480 at 70: a difference of $1,080 a month, or about $13,000 a year. Waiting isn’t always right; health, a spouse’s benefit and other savings all matter. But the stakes dwarf the cost of a plan. Our guide to advisors for retirement covers the rest of the income plan.

Stock options and RSUs. When to exercise and when to sell can move a tax bill by tens of thousands of dollars in a single year. See advisors for RSUs and stock options.

An inheritance or a windfall. The rules for inherited retirement accounts set deadlines and tax bills that are easy to get wrong in the first year. See advisors for an inheritance.

Selling a business, a divorce, a pension choice. One-time events, often the largest financial decision a person makes, and hard to undo.

If the decision is worth more than ten times the price of a one-time plan, paying for advice is easy to justify. If it’s worth less than the plan costs, you probably don’t need one for it.

What advice is worth over years

Ongoing value is harder to measure, because much of it is mistakes that never happen. The best public estimate of one of those mistakes comes from Morningstar, which compares what funds earn with what their investors actually earn after buying and selling.

Over the 10 years to the end of 2025, US funds returned 9.9% a year, while the average dollar invested in them earned 8.7%. The 1.2-point gap comes from the timing and size of investors’ purchases and sales, not from the funds.

On a $500,000 portfolio, 1.2 points is about $6,000 a year, a little more than a 1% fee on the same balance. Two cautions. The gap is an average across all fund investors, including people who already have advisors, so it isn’t proof that an advisor closes it. And if you already invest steadily and leave it alone, you aren’t paying that cost now. Being kept invested is part of the value, but on its own it barely covers a percentage fee. The rest has to come from planning: taxes, withdrawals, insurance, estate and the big decisions above.

When it isn’t worth it

• Your situation is simple and you’re handling it. A salary, a 401(k), an emergency fund and a few index funds you leave alone. Our guide to whether you need an advisor has the signs.
• You’d pay a percentage for a portfolio you could hold yourself. If the planning is what you want, pay for planning. A flat fee or a one-time plan gets it without a share of your balance.
• You need one answer and you’re buying a relationship. A single question fits an hour or two. A single decision fits a one-time plan.
• You won’t act on it. A plan nobody carries out is the most expensive kind.

How to tell if ongoing advice is still worth it

Once a year, ask your advisor for three things in writing:

1. What they did this year, in dollars. Taxes saved, a better withdrawal order, an insurance gap closed, a mistake headed off.
2. What they’ll do next year. The decisions coming up and the work they expect.
3. What you paid in total. Advisory fee plus fund and account costs, in dollars.

If the first list is mostly “managed the portfolio” and the third number keeps growing with your balance, a flat-fee planner or an hourly one may give you the same help for less. If the first list is long and specific, you’re probably getting your money’s worth.

The cheapest way to find out

If you’re unsure, buy the smallest piece first: an hour or two, or a one-time plan for the decision that’s bothering you. You’ll learn quickly whether the advice changes anything, and whether you want more of it. Choose a fee-only planner, paid only by you, so the advice isn’t tied to what they sell.
