Quick answer
The best Boldin alternative depends on why you're looking. Calm Sea suits people who want a simpler plan that puts property and loans at the centre, with retirement drawdown planning and Monte Carlo simulation, monthly pricing and no bank linking. Boldin remains the deeper tool for US retirees who want Social Security, Medicare, Roth conversion and state tax modelling. ProjectionLab suits detail-oriented FIRE planners, and Empower suits people who want free, automatic net worth tracking.
Boldin features and prices checked October 2026 on its own website and help centre.
Introduction
Boldin, which was called NewRetirement until its rebrand, is one of the most popular retirement planners in the US. It models income, Social Security, taxes, healthcare and spending in a single plan, and its free Basic plan lets anyone build one. Even so, many people search for a Boldin alternative. Some live outside the US and find its tax rules don't fit. Some want property and mortgages at the centre of their plan. Others want a monthly price, or just want to compare before they commit.
This guide compares Calm Sea and Boldin side by side: what each one does, what each one costs, and where each is the stronger choice. It's written by the Calm Sea team, so we've tried hard to be fair. Boldin facts come from its own pricing page, homepage and help centre, and we say plainly where it does more than Calm Sea.
If you're comparing a wider field, our roundup of the best FIRE tracking apps covers six options, and our ProjectionLab alternative guide compares Calm Sea with another popular planner.

What Boldin Does
Boldin is a do-it-yourself retirement and financial planning tool. You build a plan from your income, savings, retirement accounts, home, debts and spending, and Boldin projects how it plays out through retirement. Its homepage lists modelling for taxes (state rules, itemised deductions and brackets), income from work, Social Security, annuities and pensions, real estate purchases and sales, debts such as mortgages and student loans, budgets, and medical costs including Medicare and long-term care.
Boldin has three ways to pay, as of October 2026:
- Basic is free. It lets you build a personalised plan, try "what if" scenarios and use more than 100 inputs, with limited questions to Boldin AI.
- PlannerPlus costs $168 a year, billed annually after a 14-day free trial. It adds Monte Carlo analysis, account linking through data aggregators, state and federal tax projections, a Roth conversion explorer, withdrawal strategy, healthcare cost estimates, side-by-side scenarios and unlimited Boldin AI.
- Boldin Advisors offers a one-off retirement plan checkup with a CERTIFIED FINANCIAL PLANNER™ professional for a flat fee of $3,200.

Why People Look for a Boldin Alternative
Boldin is a capable product, so the reasons people look elsewhere are mostly about fit rather than flaws.
Living outside the US. Boldin is built around US rules. Its own help centre says PlannerPlus "does not have features for the retirement and tax regulations of other countries", can't apply non-US tax rates, and doesn't support equivalents to retirement accounts like the 401(k) outside the US (Boldin help centre). Someone in the UK, Europe or elsewhere can still project a plan, but Social Security, Medicare and required minimum distributions are modelled on US rules.
Property-heavy finances. For many households the biggest assets are a home and an investment property, with a mortgage on each. Boldin models real estate and debts, but they sit inside a retirement plan built around income and accounts. Some people want a view where property, loans and equity are front and centre.
Linking accounts. Account linking is one of PlannerPlus's selling points, and it saves time. Some people prefer not to connect their bank and investment logins to a planning tool at all.
Wanting a second opinion. A plan is only as good as its assumptions. Running the same numbers through a second tool is a sensible way to check that a projection isn't the product of one model's quirks.
Calm Sea vs Boldin: Feature Comparison
The table compares the two tools on the points that matter most when choosing a Boldin alternative. "Not stated" means the vendor's own website doesn't mention the capability. It doesn't necessarily mean the feature is missing.
| Feature | Calm Sea | Boldin |
|---|---|---|
| Free plan | Yes, Simple (no saving) | Yes, Basic |
| Paid price | $9/mo or $89/yr | $168/yr (PlannerPlus) |
| Monthly billing | Yes | Annual only |
| Free trial | Free plan | 14 days |
| Monte Carlo | Yes | PlannerPlus |
| Property | Yes, equity and LVR | Yes, buys and sales |
| Mortgages and debts | Linked to assets | Yes |
| Retirement drawdown | Yes | Withdrawal strategy |
| Social Security | Planned future feature | Yes, explorer |
| Tax estimation | Yes | US, PlannerPlus |
| Roth conversions | Planned future feature | PlannerPlus |
| Country coverage | Yes, several supported | US rules only |
| Bank account linking | No, manual entry | PlannerPlus |
| Advice service | No | $3,200 plan checkup |
A few notes on the table:
- Pricing for Calm Sea comes from its pricing page. Boldin's Basic plan is free and PlannerPlus is $168 a year. Prices are in US dollars.
- Tax: Boldin's help centre notes that free users get a flat 3% state tax rate, while PlannerPlus adds detailed state and federal tax projections.
- Account linking: Boldin says PlannerPlus can link accounts through the "top 3 aggregators". Calm Sea has no bank linking; everything comes from numbers you enter.
- Country coverage: Boldin is designed for US households. Calm Sea isn't built around one country's accounts or rules, so the same plan works wherever you live.
Where Boldin Is the Stronger Choice
An honest comparison has to say where the other tool does more. Boldin is ahead in several areas, especially for US retirees.
US retirement income planning
Boldin's Social Security Explorer, pension and annuity modelling, required minimum distributions and Medicare costs are built for the US system. If you're in the US and deciding when to claim Social Security, those tools answer questions a general planner can't.
Tax and Roth conversion modelling
PlannerPlus includes state and federal tax projections and a Roth conversion explorer. For a US household, the order in which accounts are drawn down and converted can change lifetime tax by a lot, and Boldin is built to model it. If that's central to your decision, Boldin (or ProjectionLab) is the better fit.
Automatic account updates
Because PlannerPlus links accounts through aggregators, balances can update without manual entry. If you'd rather not update values yourself, that's a real time saver.
Education, AI and human help
Boldin offers classes, planning Q&A sessions, coaching and an AI assistant that answers questions about your plan. Its advisor service adds a review by a CERTIFIED FINANCIAL PLANNER™ professional, which matters if you want a human to check your plan.
Where Calm Sea Is the Stronger Choice
Calm Sea takes a different approach: a clear, long-range picture of your whole net worth, built from numbers you enter, without needing to master a large model first.
Property and loans at the centre
Calm Sea treats real estate as a core asset class rather than an add-on. You add each property with its value and growth rate, link the mortgage secured against it, and the dashboards show value, equity, debt and loan-to-value ratio (LVR) over time. Our real estate guide walks through the setup. For people whose wealth is mostly in a home and an investment property, that view is often the most useful one.
Not tied to the US
Calm Sea isn't built around US accounts, Social Security or Medicare. You enter your own assets, income, expenses and growth rates, and several countries are supported. That makes it a practical Boldin alternative for people outside the US, where a US-centred plan needs workarounds.
Accumulation and drawdown in one view
Calm Sea projects your net worth forward while you build wealth, then models the drawdown phase: how your savings and income could fund your spending through retirement, year by year, and how long your money could last. A Monte Carlo simulation then tests the plan across many randomised market scenarios, so you can see how likely it is to hold up rather than relying on a single growth rate.
Private by design
Calm Sea never asks for bank logins. There's no read access to your accounts and no syncing. The trade-off is that you update balances yourself, which many people do monthly or quarterly as a check-in. Our guide on how to track net worth covers a simple routine.

Who Each Tool Is Best For
| If you want to... | Better fit |
|---|---|
| Plan when to claim Social Security | Boldin |
| Model US taxes and Roth conversions | Boldin |
| Link accounts for automatic updates | Boldin |
| Put property, mortgages and LVR first | Calm Sea |
| Plan outside the US | Calm Sea |
| Keep bank logins out of your planner | Calm Sea |
Boldin is best for US households approaching a traditional or early retirement who want Social Security, Medicare, tax and Roth conversion modelling in one place, and who are happy to link accounts. Its free Basic plan is a good place to start.
Calm Sea is best for people whose finances include property and loans, people outside the US, and anyone who wants a clear long-range view of when they could reach financial independence and how long their money could last, without linking bank accounts.
Plenty of people use both: a detailed US retirement income plan in one tool and a quick, property-focused check in another.
Other Boldin Alternatives Worth Knowing
Calm Sea isn't the only option. Depending on what you need, these Boldin alternatives may fit better.
ProjectionLab
ProjectionLab is a detailed FIRE planner. Its free Basic plan includes Monte Carlo simulation and historical backtesting, and Premium, at $129 a year, adds cash-flow projections, tax estimation, withdrawal strategies and Roth conversions. It doesn't link directly to accounts. It's strongest for detail-oriented planners who enjoy building a model; our ProjectionLab alternative guide compares it with Calm Sea in depth.
Empower Personal Dashboard
Empower's free dashboard links to your accounts and tracks net worth automatically, with a retirement planner on top that runs a Monte Carlo simulation. It's a good fit if you want automatic tracking for free and don't mind sharing account access.
A spreadsheet
A spreadsheet gives you full control and costs nothing. The trade-off is that you build every formula yourself, and Monte Carlo simulation is hard to do well in a spreadsheet.

How to Choose a Boldin Alternative
A few questions usually settle the choice.
Where do you live? If you're in the US and Social Security, Medicare and US tax rules matter, Boldin's depth is hard to match. If you live elsewhere, a tool that isn't built around US accounts will need fewer workarounds.
What's the main question you want answered? If it's "when could I retire, and will my money last?", a projection with drawdown and Monte Carlo covers it. If it's "when should I claim Social Security, and how much should I convert to Roth each year?", you need US-specific modelling.
How much of your wealth is in property? If most of it is, choose a tool that shows equity, debt and LVR clearly, not just a single property value.
Are you willing to link accounts? Automatic syncing saves time but shares access. Manual entry keeps things private but needs regular updates.
What are your withdrawal assumptions? Whichever tool you choose, the withdrawal rate drives the result. The 4% rule is a common starting point, and our guide to the safe withdrawal rate explains why the right rate depends on your timeline. You can test different rates in the free safe withdrawal rate calculator, which includes a Monte Carlo simulation, before signing up for anything.

Frequently Asked Questions
What is the best Boldin alternative?
It depends on what you need. For a simpler, manual-entry plan centred on property and loans, with drawdown planning, Monte Carlo simulation and support outside the US, Calm Sea is a strong fit. For detailed FIRE modelling with backtesting, ProjectionLab is the closest match. For free, automatic net worth tracking, Empower Personal Dashboard is popular.
Is Boldin the same as NewRetirement?
Yes. Boldin is the new name for NewRetirement. Its website footer still names the company as NewRetirement, Inc., doing business as Boldin.
Is Boldin free?
Boldin has a free Basic plan for building a plan and trying "what if" scenarios. Monte Carlo analysis, account linking, detailed tax projections and the Roth conversion explorer are part of PlannerPlus, which costs $168 a year after a 14-day free trial, as of October 2026.
Can I use Boldin outside the US?
You can build a plan, but Boldin's help centre says PlannerPlus doesn't support other countries' tax rules or retirement schemes and can't apply non-US tax rates. Calm Sea isn't tied to one country's accounts or rules, so it can be used wherever you live.
Does Calm Sea link to my bank accounts like Boldin?
No. Calm Sea is entirely manual-entry, so it never asks for bank logins. Boldin's PlannerPlus can link accounts through data aggregators, while its free plan works from the numbers you enter.
Calm Sea is a personal finance planning tool. Nothing in this article constitutes financial advice.
