I’m considering using Boldin for retirement planning, but I’m unsure if it’s reliable or worth the cost. I’ve seen mixed information online and don’t know if the projections and features are accurate enough for long‑term planning. Can anyone who has actually used Boldin share their experience, including pros, cons, and whether you’d trust it with your retirement strategy?
I tested Boldin for about 3 weeks alongside NewRetirement and a plain Excel sheet. Short version. It is decent if you know its limits. It is not magic.
Here is what I ran into.
- Accuracy of projections
I plugged in:
• Age 38
• 140k income, spouse 90k
• 620k invested, 70/30 mix
• Saving 30k per year, plus 10k employer match
Boldin defaulted to 6.5 percent return and 2.5 percent inflation.
When I set the same in Excel and NewRetirement, Boldin’s “success rate” and ending balances were close, but it pushed a bit higher spending in retirement than I would trust. It assumed smooth returns. No sequence of returns risk modeling, at least not in a transparent way.
If you lower returns to 4.5 percent and use 3 percent inflation, the plan looks much more conservative. That felt more realistic. Boldin does not force you to pick conservative numbers, so you need to dial that in yourself.
- Tax handling
Federal tax brackets looked fine for current year. Long term assumptions felt opaque. It projects future brackets off inflation. That is one guess among many. State tax support varies by state. In my state (CA) it matched my CPA’s rough numbers within a few hundred dollars on a 200k income, which is “good enough” for planning.
Roth conversions modeling was basic. It let me set a target conversion window but did not show rich “what if” charts like NewRetirement or a custom spreadsheet. If you plan to do detailed tax optimization, Boldin felt light.
-
Spending modeling
You can set multiple spending phases. For example:
• 90k per year from 55 to 70
• 70k per year after 70
• Separate bucket for healthcare
That part worked ok. The issue is behavior. Boldin assumes you stick to the plan and inflation adjustments. There is no behavioral buffer. I had to build my own margin by entering 10 to 15 percent higher spending than I expect. -
Risk and Monte Carlo
Their Monte Carlo engine used 1000 paths when I last checked. It let me pick conservative, moderate, or aggressive assumptions. It did not expose the exact volatility inputs. That bugged me a little. Compared to Portfolio Visualizer runs on the same allocation, Boldin’s “90 percent success” felt a bit optimistic on aggressive settings. On conservative settings it lined up closer. -
Interface and usability
Nice dashboard. Easy to plug in accounts. Fees, employer match, and asset allocation controls were ok. Some quirks:
• Hard to model weird stuff like “sell rental at 63 and move to lower COL area.” You can hack it with custom cash flows, but it feels clunky.
• Limited support for special situations like equity comp or small business sale. -
Reliability and cost vs value
If you treat Boldin as:
“Front end for long term projections based on your own conservative inputs”
then the price is fine. If you expect:
“Perfect, precise planner that replaces thought and a spreadsheet”
then it is not worth the money.
What I liked:
• Faster than Excel once set up.
• Good at showing tradeoffs between retiring at 60 vs 63 vs 65.
• Clear “probability of success” metrics.
What bugged me:
• Some black box assumptions.
• Slight optimism in base settings.
• Light tax detail for high earners with complex stuff.
If you try it, here is what I would do:
- Turn down return assumptions for stocks and bonds. For example, 4 to 5 percent real for stocks, 0 to 1 percent real for bonds.
- Use higher inflation on healthcare. I used 4.5 percent.
- Add 10 to 20 percent to your expected spending to stress test.
- Compare one Boldin scenario to a simple spreadsheet. If it is close, you are fine. If it wildly diverges, trust the spreadsheet and adjust Boldin inputs.
Personal verdict. Reasonable tool for planning ranges. Not a single source of truth. If you go in with that mindset and double check big decisions with a fee only planner or at least an Excel model, it is “worth it.” If you want plug and play certainty, you will be disappointed.
I’m in roughly the same camp as @ombrasilente, but I use Boldin a bit differently, so I’ll add where my experience diverges.
I ran Boldin alongside NewRetirement and Fidelity’s planner for ~6 months while I was deciding if I could semi‑retire at 52. For context: two incomes, a couple rentals, HSA, taxable account, mix of pre‑tax and Roth.
Where Boldin worked well for me:
-
Big picture “can I retire” stuff
For basic questions like “52 vs 55 vs 60” it’s solid. The slider‑style adjustments on retirement age, savings rate, and withdrawal rate made it faster to iterate than spreadsheets. I don’t totally agree that it’s “too optimistic” by default; I actually found the defaults kind of middle‑of‑the‑road once I toggled their “conservative” risk profile and didn’t mess with the capital market assumptions. -
Behavior / guardrails
One place I think it did better than @ombrasilente gave it credit for: the spending guardrails. They’re not super obvious, but if you dig in, you can turn on “dynamic spending” that cuts back spending somewhat when markets are down and relaxes when they’re up. It’s not Guyton‑Klinger level precision, but it at least keeps you from assuming robotic inflation‑only spending forever. -
Social Security and pension stacking
It handled my mix of:- early claiming vs delayed claiming scenarios
- a small COLA pension starting at 60
better than my homegrown spreadsheet, mostly because it is annoying to build those timing offsets yourself. Projections for SS were in the same ballpark as SSA calculator, so that felt fine.
Where it annoyed me:
-
Black box capital market assumptions
Agree with @ombrasilente here. You cannot easily see “stock volatility is X, bond volatility is Y, correlation is Z.” I ended up backing into it by comparing to Portfolio Visualizer and some Bogleheads‑style assumptions. Not ideal. If you are a data nerd, this will bug you. If you are not, you might never notice. -
Sequence of returns stuff is undercooked
They say it is handled in Monte Carlo, but you do not get tools like: “Here’s a bad first‑10‑years path vs a good first‑10‑years path.” So, yes, sequence risk is “in there,” but not in a way that helps you think about it. I solved that by running a few custom stress tests: very low returns for the first decade, then normal. You can hack it with scenarios, but it is more effort than it should be. -
Complex income events
Stock comp, business sale, one‑off liquidity events: still clunky. You can model them with custom cash flows, but once you get more than 4 or 5 special events, the plan starts to feel like a Jenga tower. At that point Excel is frankly easier, because you see every formula.
Reliability & long‑term projections
This is the part you specifically asked about. My take:
-
Boldin is not really more or less “accurate” than any other mainstream planner if you:
- set conservative return assumptions
- don’t take the success rate percentage as gospel
- periodically refresh your data
-
Over a 30+ year horizon, the difference between Boldin, NewRetirement, and a well‑built spreadsheet was mostly noise for me. Ten, maybe fifteen percent swings in “probability of success,” which is not enough to change my life decisions, but enough to remind me these tools are fuzzy.
-
Where people get burned is using optimistic defaults, then believing a 95 percent success rate equals “I’m bulletproof.” I treated 85–90 percent as “good,” but only if it still looked okay when I:
- bumped inflation up
- bumped medical up specifically
- cut market returns by 1–2 percentage points
Is it worth the cost?
For me it was worth it for 1–2 years around the retirement decision point, not as a forever subscription.
Rules of thumb I’d use:
-
Worth paying for if:
- You’re within 10–15 years of retirement.
- You have multiple account types and some nontrivial decisions (Roth conversions, SS timing, pension options).
- You are willing to sanity‑check key scenarios elsewhere, not just trust the colored gauges.
-
Probably not worth it if:
- You are early career and just need “save a lot, invest in index funds.”
- You have very simple finances and can easily model everything in a free spreadsheet.
- You expect it to give a single, precise “you’re safe at $X” number.
If you do try it, instead of repeating @ombrasilente’s steps, I’d focus on these three experiments:
- Build two very different return / inflation sets: “rosy” and “ugly,” then see if your plan still looks livable in the ugly one.
- Turn on their dynamic spending / guardrails and see how much it actually cuts in bad paths. That tells you how fragile your lifestyle is.
- Create a scenario where you retire during a 2000–2002 or 2008‑style start. Not perfect, but it’s a decent gut check for sequence risk.
If Boldin says you’re fine in those stress tests, and a bare‑bones spreadsheet lands in the same ballpark, I’d personally call it “reliable enough” for long‑term planning, with the huge asterisk that no tool replaces revisiting the plan every year or two.
