Retirement planning tools

Everything beyond the core 403(b) calculator lives here — tools for comparing states, stress-testing a plan against market variability, and planning as a household. Every one of them runs in your browser, free, with no sign-up: nothing you type is sent anywhere.

Which one do I need?

Paid plans deepen these tools — charts, after-tax figures, survivor and timing analysis — but never lock you out of them. See what each plan adds →

State Tax Comparison
See what your pension is worth side by side — 2 states free, up to 5 on Premium.
Retirement Projection Suite Free · Pro depth
Run your 403(b) through hundreds of simulated market paths. Free: odds of hitting your target. Pro: the year-by-year range chart and live what-if.
Joint / Household Analysis Free · Premium depth
Two pensions, one household. Free: combined income table. Premium: after-tax income, survivor benefit, retirement-timing comparison.
Health Insurance Bridge Free · Pro depth
Retiring before 65? Price the years before Medicare. Free: total and monthly cost. Pro: year-by-year breakdown and what one more working year saves.
Pension vs Lump Sum Free · Pro depth
Offered a buyout? Free: present value and break-even age. Pro: the return the cash must earn to match the pension, and the year it runs out.
Social Security Timing Free · Pro depth
Claim at 62, 67 or 70? Free: your full retirement age and both extremes. Pro: all nine ages and the break-even. WEP and GPO no longer apply.
RMD Calculator Free · Pro depth
When the IRS starts forcing withdrawals from your 403(b), how much, and what it costs in tax.
Side by Side Free
Open any two of these tools on one screen — lump sum next to Social Security timing, insurance bridge next to the projection suite.
Pension Formulas, All 50 States Free
The benefit formula behind every state pension — average salary × multiplier × years — and what each state's teachers pay in for it.
403(b) vs 457(b) Free
Offered both? They have separate limits, so you can use both. One of them has no 10% penalty if you retire before 59½.
State Rankings Free
All 50 states ranked: pension tax, the 14 states where teachers get no Social Security, contribution rates and average salaries.
Best States for Teacher Retirement Free
The states that take nothing from a pension, ranked by what they pay — and the trade-off each one hides.
Open Dataset Free · CC BY
Every figure behind these tools, as JSON and CSV: pension tax by state, benefit formulas, contribution rates, Social Security coverage.

Everything here runs in your browser and needs no account. Paid plans add depth — charts, schedules, after-tax figures — never access.
