2. New Retirement

Cost: Free or $120/year

New Retirement offers free and premium retirement calculators, along with optional access to financial planners. Free users can build a personalized strategy and run multiple “what if” scenarios. 

I personally like the premium PlannerPlus plan, which has over 100 customizable filters for more precise projections regarding inflation, budgeting, income, and taxes. You can also run a Monte Carlo analysis, compare scenarios, and view in-depth charts unavailable to free users.   

The Basic plan is fee-free but has limited capabilities to the PlannerPlus tier. The paid plan costs $120 when billed annually and has a 14-day free trial. Access to a certified financial planner costs extra and you can book a free discovery call.

3. OnTrajectory

Cost: Free or $99/year

It’s easy to make in-depth retirement projections with OnTrajectory by forecasting several decades of personal finance performance. Start by entering your income, expenses, account details, and assumptions to receive a free financial plan and one alternate scenario.

The Unlimited plan offers these additional features: 

  • Customizable assumptions
  • Unlimited scenarios
  • Monte Carlo analysis
  • Spending optimizations
  • Optimized withdrawals from specific accounts
  • Debt reduction strategies

Upgrading costs $99 per year or $12 monthly and is worth it to easily compare multiple scenarios and have more customization. I have used this service in the past and really like the numerous customizable assumptions that make it easier to get a realistic projection. 

4. cFiresim

Cost: Free

You will appreciate cFiresim if you’re pursuing FIRE and looking for a free retirement calculator. It has a simple interface that makes it easy to enter your details without having to create an account.

This tool lets you enter the following inputs to run a simulation:

  • Retirement year
  • Portfolio value and asset allocation 
  • Initial yearly spending
  • Retirement income (Social Security, pensions, etc.)

The calculator lets you apply adjustments to factors including inflation, retirement income and portfolio rebalancing to modify your simulations. 

Calculations use historical returns dating back to 1871 for multiple investment assets, including stocks, bonds, and gold. There are more than 80 inputs available to backtest your savings progress against various market cycles.

5. MaxiFi

Cost: $109 or $149 annually

MaxiFi is an extensive paid retirement calculator with many forecasting tools that can make personalized suggestions and extensive forecasts. It can help evaluate your present and future finances.

Its most unique feature is a Living Standard Monte Carlo Analysis which can offer more customization while running the various financial tests. You can enable two risk-based investment strategies and your annual spending habits to forecast your upside and downside potentials.

It’s possible to run unlimited what-if scenarios that can include relocation, escaping the rat race, job changes, and Roth IRA conversions. 

This platform also looks for ways to maximize your Social Security benefits, reduce your taxes, and estimate your life insurance benefits. Other retirement calculators may focus exclusively on your retirement assets and target withdrawal rate to estimate your affordability.  

Two premium household plans are available for a self-directed experience. Financial advisor sessions are available at an extra cost.  

6. Flexible Retirement Planner

Cost: Free

Run a free Monte Carlo analysis through Flexible Retirement Planner. You can download the planner and start entering your retirement plan details to find out your probability of success. It bases your calculations on the accumulation and draw-down phases which can make its result differ from other programs.

This is a popular program within the Boglehead community as it’s free, customizable, and lets you save your data. Further, some platforms require a paid membership to run Monte Carlo scenarios, and the free access is what I appreciate most about this service.   

For instance, the calculator lets you modify the inflation rate, investment allocation, retirement cash flows, and tax rate. Other free tools may only provide a general rule of thumb to estimate your portfolio value.

7. Fidelity Investments

Cost: Free

The Fidelity Investments retirement calculator can be a natural starting point if you invest through this online brokerage. Non-customers are able to receive a retirement score and brief estimates after answering six simple questions about their current retirement planning progress.

This score also includes estimates about how much Fidelity thinks you need each month to pay the bills and your available funds based on your current nest egg size and savings rate. 

You can recalculate your score by adjusting these variables:

  • Retirement age
  • Monthly savings
  • Investment style (risk tolerance)
  • Standard of living in retirement

Other in-depth financial requirements require creating an account with this free investing app. Some of the additional options include retirement income estimates, retirement decision guides, savings goals, and guaranteed income estimates. 

8. Vanguard

Cost: Free

Vanguard is a popular online brokerage for index fund investors and this platform offers several free retirement planning calculators and worksheets as well. Primarily, this tool estimates your monthly expenses and portfolio income in retirement based on your current savings rate and accumulated reserves.

Unfortunately, this isn’t an all-in-one retirement simulator like several other free and paid options on this list. You may need to use several different calculators to estimate your retirement income, expenses, and required minimum distributions (RMDs). 

There are also planning tools for investment analysis and education costs to help assess your non-retirement goals. 

For hands-on help from this discount brokerage, you may consider enrolling in Vanguard Personal Advisor after reaching $50,000 in investable assets. This service offers managed portfolios along with financial advisor access. A 0.30% annual advisory fee applies.   

9. AARP Retirement Calculator

Cost: Free

You can receive a quick retirement progress assessment with the AARP retirement calculator. I was able to get a basic evaluation in less than five minutes by entering core financial details regarding myself and my wife. 

The calculator inputs include your annual income, current retirement balance, monthly contribution rate, and anticipated lifestyle expenses. 

This tool produces two financial estimates:

  • Minimum balance needed to retire
  • The amount you will have saved

If there’s a funding gap, the calculator estimates by how much you must reduce your spending. It’s easy to make adjustments to your financial information to modify your calculation.

This free tool doesn’t require an AARP membership, but joining lets you enjoy travel and shopping discounts. You can also complete short tasks and earn rewards points that are exchangeable for discounted gift cards, sweepstake entries, local deals, and charitable contributions.  

10. Networthify

Cost: Free

Networtify helps you estimate how soon you can retire early with your current savings rate. You can perform a quick back-of-the-napkin calculation referencing your current annual income, savings, and expenses.  

Additional inputs include your current portfolio value, annual return on investment, and withdrawal rate. Unfortunately, you cannot add assumptions such as incremental salary increases to help get a more precise calculation.

Still, this free calculator can encourage you to earn more interest on your money along with reducing expenses to achieve early retirement sooner.

A table displays your hypothetical investment returns, percent of expenses covered by investment returns, and net worth changes. You will see these estimates for each calendar year until reaching financial independence.
