What makes us different

Most retirement calculators ask for your age, income, and a single average rate of return, then hand back one tidy number. Life does not work that way. Markets swing, medical costs arrive early, raises land late.

We start from the detailed base plan you build, then generate 100 randomized versions of it. Instead of one guess, you get a range of realistic outcomes, so you can see how much room for error your plan really has.

How it works

  1. 1 Fill out the input sections with your income, balances, contributions, debts, and retirement timing.
  2. 2 Run the calculations. We build 100 randomized scenarios month by month from your base plan.
  3. 3 Review your savings and retirement outcomes by age, then adjust inputs and rerun to compare plans.

What you can plan for

Each section is its own short form. Fill in what you know, come back and refine the rest later.

General

Your age, household details, and the basic timeline your whole plan is built on.

Healthcare

Medical and Medicare costs, including how they grow as you age.

Savings

Current balances and monthly contributions across each of your accounts.

Retirement

Retirement accounts, when you plan to retire, and what you expect to spend.

Social Security

Expected benefits and the age you plan to start claiming them.

Rates

Growth, inflation, and raise assumptions, set overall or per account.
