How it works

Three steps from today's balance to your retirement date.

Each part of the app does one job, and each builds on the one before it.

  1. 01 · Track

    Snapshot what you own and owe

    Add your accounts once, then record balances whenever you like. Each entry captures your net worth, and the charts fill in as you go.

  2. 02 · Direct

    Give every paycheck a plan

    Schedule contributions and extra principal payments, and put the big expenses and purchases you see coming on the calendar.

  3. 03 · Project

    See where it all leads

    Your balances and plans combine into a projection of net worth and retirement income. Change a plan, and the projection updates.

Features

Built for people who like to see the math.

A balance sheet with history

Assets and liabilities in one place, grouped by type, with net worth charted over time.

Loans that pay themselves down

Mortgages, auto, and student loans amortize in your projections, extra principal payments included.

Big expenses, on the calendar

Plan tuition, travel, or a new roof, and see how each one shapes the balances of the account that pays for it.

Property you can plan for

Model a future home, vacation home, or rental, with its down payment and mortgage, before you sign anything.

Retirement, projected

Set your birth date and target retirement age to see the income your plan can support.

On your phone, too

Designed for desktop and mobile. Add it to your home screen and it opens like an app.

Your data

Simple by design. Yours by default.

  • No bank logins. You enter balances yourself, so you never hand your bank credentials to anyone.
  • Private to your account. Your plans and balances are visible only to you when you're signed in.
  • Nothing to install. It runs in your browser on any device, and you can add it to your home screen if you like.

Start with today's balances.

Your first entry is the hardest part. After that, every update sharpens the picture.
