Boldin Financial Planning: The Retirement Tool ETF Investors Actually Use

I've spent the last couple decades helping regular people build simple, low-cost ETF portfolios. No fancy stock picking. No market timing. Just broad index funds like total market and international, held for decades. The question that comes up again and again is this: how do I know my plan will survive the real world? Boldin financial planning turned out to be one of the few tools that actually gives a useful answer.

Boldin (they used to be called NewRetirement until the rebrand in 2024) isn't another basic retirement calculator. It's a full modeling platform. You feed it your life — income, spending, every account, Social Security, pensions, house, debts, the works — and it shows you year-by-year projections, cash flow, taxes, and net worth. Then you get to poke at it. Retire three years early? What if the market drops 30% right after you stop working? What if you convert some traditional IRA money to Roth while rates are low? It runs the numbers without the sales pitch.

The thing is, most retirement calculators assume some average return and call it good. Boldin lets you stress-test the exact ETF mix you're actually holding.

What Boldin Financial Planning Really Is

At its core, Boldin is a comprehensive financial planner built for regular humans who want to stay in control. You create one master plan, then spin off as many "what if" versions as you want. The free tier already lets you build a solid baseline and run a handful of scenarios. The paid tier (PlannerPlus) unlocks the serious stuff: 250-plus inputs, account linking, detailed tax projections for every state, Roth conversion modeling, Monte Carlo simulations, side-by-side scenario comparisons, and way more charts.

They've added AI now too. Type a plain-English question like "what happens if I delay Social Security until 70 and live off ETF dividends for the first few years?" and it pulls from your actual plan to answer. It's not magic, but it beats hunting through menus.

Over 350,000 people have used it to manage more than $300 billion in assets. Users who plan this way tend to end up with more retirement savings and higher odds of success. That tracks with what I've seen in practice.

Is Boldin Actually Free?

Yes and no. The basic version costs nothing and is genuinely helpful for getting your bearings. You can input your ETF holdings, set reasonable long-term returns (I usually use 6.5–7.5% nominal for a diversified stock-heavy portfolio, with appropriate volatility), and see the big picture.

For most people serious about retirement, though, PlannerPlus at $12 a month or $144 a year is where the real value shows up. You get unlimited AI questions, the full Roth Conversion Explorer, Monte Carlo runs (1,000 simulations), better tax modeling, and the ability to keep multiple detailed scenarios live at once. A 14-day trial is usually available, so you can kick the tires without risk.

The $2,800 flat-fee advisor review exists for folks who want a CFP to look everything over. Some people love it. Others (especially DIY ETF types who already understand asset allocation) find it expensive for what they get. I usually steer clients toward mastering the planner themselves first.

Why Boldin Works So Well With ETF Portfolios

This is where it clicks for me. ETFs reward patience and simplicity. Boldin respects that.

You can model each account's expected return and volatility separately — say 7.2% and 14% standard deviation for your total U.S. stock ETF allocation, lower numbers for bonds. The Monte Carlo engine then runs a thousand possible market paths and tells you the probability your money lasts. I've seen clients go from "I think this might work" to "okay, 87% chance of success even in bad sequences" in one sitting. That kind of clarity changes how people feel about holding through volatility.

The tax tools are particularly ETF-friendly. Qualified dividends and long-term capital gains get modeled correctly in taxable accounts. You can test different withdrawal orders — sell from taxable first, let traditional accounts keep growing tax-deferred, then tap Roth later. The Roth Conversion Explorer is especially powerful. It shows you exactly how much to convert each year to stay in lower brackets and avoid Medicare IRMAA surcharges, without overpaying taxes upfront. For someone holding a big traditional IRA full of low-cost ETFs, that's often worth thousands in lifetime tax savings.

You can also play with real-world wrinkles: part-time work for a few years, big healthcare expenses in your 80s, downsizing the house, even gifting to kids. The planner handles it all without forcing you into some rigid "4% rule" straitjacket.

Real User Feedback and My Take

Reviews are mostly strong. People like the depth without the advisor price tag. The interface has improved a lot over the years, though it still takes a little time to learn if you're detail-oriented. Some folks complain the learning curve feels steep at first. Others say once everything's loaded, updates are quick.

Compared to MaxiFi, Boldin feels more flexible for ETF investors who like to adjust assumptions or spending year to year. MaxiFi leans harder into strict economic modeling and consumption smoothing. Both are solid. For buy-and-hold passive types, Boldin usually wins on scenario flexibility and tax nuance.

A few users have griped about the advisor tier feeling rushed or generic. That matches what I've heard. If you're already comfortable with ETF asset allocation and long-term thinking, you probably don't need it.

How I Actually Use Boldin With Clients

When someone comes to me with a portfolio heavy in low-cost ETFs, we load their exact holdings and expected returns based on history, not hype. We set inflation at 2.5–3%, longevity to 95 or 100, and run the baseline. Then we test the scary stuff: sequence-of-returns risk right at retirement, higher-than-expected healthcare costs, living longer than planned.

Almost every time, the plan shows they're in better shape than they feared — or reveals one or two small tweaks (a little more international exposure, a Roth ladder, delaying Social Security) that push the success rate from "pretty good" to "very comfortable." No speculation required. Just data.

The signature line around here has always been the same: time in the market beats timing the market. Boldin financial planning simply gives you the numbers to believe it.

Should You Start With Boldin?

If you're already investing in diversified, low-cost ETFs and you want to stop guessing about retirement, yes. Begin with the free version. Spend an evening inputting your real numbers. Run a couple of "what if" scenarios. See what surfaces.

Most people I work with end up upgrading to PlannerPlus because the extra modeling power is worth it once they see the gaps it fills. You don't have to be a spreadsheet nerd. You just have to care enough to run the numbers properly.

Boldin won't pick your ETFs for you. It won't promise 12% returns forever. What it will do is show you, clearly and honestly, whether the simple, patient approach you're already taking is likely to work. For ETF investors, that's usually the only confirmation we really need.
