Granary

For users

The fastest way to know
you'll be OK.

Five questions. About five minutes. Then a real, tax-aware projection you can argue with — because every number on it opens up and shows you the formula underneath.

Free tier, no card required. Try Pro free for 7 days — cancel anytime, not charged until day 8.

Setup

Five questions stand between you and a plan.

No account tree to build, no forty-tab workbook to learn. Rough answers are fine — every one of them is editable forever, and the projection sharpens as you do.

  1. 1

    How old are you?

  2. 2

    When do you want to retire?

  3. 3

    What do you earn?

  4. 4

    How much have you saved?

  5. 5

    How are you invested?

You see a real projection at minute five — not a lead-capture form, not a “book a call” button.

Granary Academy

Why people stay

Three moments
you won't get from a calculator.

01

An advisor's read, every time you log in.

Not a generic article about the 4% rule — a plain-English analysis of your numbers, refreshed on the dashboard. Where the plan breaks, why it breaks, and the single highest-leverage fix.

AI Insight · today
Illustrative example

Your plan runs out at age 87 because your withdrawal rate is 1.2% over safe.

Delaying SS to 70 adds 6 years of coverage.
Trimming discretionary by $400/mo gets you to 92.
Roth conversion ladder saves $48k in IRMAA.

02

Drag a slider. Watch the future move.

What if I retired two years earlier? What if I saved another $500 a month? Other tools make you save a scenario and compare it later. Granary re-animates the projection while your finger is still on the slider — try it right here.

No black box. Click any number.

Every key figure on the dashboard is auditable. Click your net worth, your cash flow, your retirement readiness — a drill-down opens with the exact formula and the inputs that fed it. If you don't trust a number, take it apart.

Fair questions

The four reasons people don't sign up.

I already have a spreadsheet.

Then you already know the hard part isn't the arithmetic — it's keeping the tax rules current. Granary carries 2026 federal and 50-state tables, the SECURE 2.0 RMD ages, the Social Security taxability ramp, and the six IRMAA tiers, and updates them when Congress does. Import your numbers and keep the spreadsheet as a second opinion.

I have a financial advisor.

Good — keep them. Granary is what you do between the annual visits, when a question comes up in October and the next appointment is in March. The math is exposed rather than hidden, so you can bring your advisor a screenshot and they can check the assumptions instead of re-keying your life into their software.

I'm not close enough to retirement for this.

The years when a plan changes the outcome are the ones furthest from retirement, because that's when a contribution change or a Roth conversion has decades left to compound. Granary's Coast FIRE and opportunity-cost views are built for exactly that distance.

What if the numbers are wrong?

Every key figure drills down to the formula and the inputs that produced it — check it by hand if you want to. 280+ calculation assertions plus a unit-test suite run in the deploy pipeline; if either fails, the deploy fails. When a real user caught a state-tax bug it was fixed in 48 hours with a regression test attached.

Proof, not promises

The math is tested before you ever see it.

Most retirement calculators take shortcuts — a 22% flat tax, no RMDs, hand-waved inflation. Granary models what the IRS and SSA publications actually say, bracket by bracket, year by year.

280+

Calculation assertions passing

Plus a separate unit-test suite. Both run in the deploy pipeline — if either fails, the deploy fails.

OBBBA-current tax tables

Federal + 50 states. Standard deduction, brackets, FICA, NIIT, IRMAA — updated whenever the rules change.

A real user caught a state-tax error. Fixed in two days, with a regression test so it can't come back.
