Know what your equity is actually worth after tax. Cliff turns RSU grants into one honest number: what lands in your bank account, and when.
Your equity package has a big number on it. Cliff tells you what's actually left after tax.
Most tools show you a headline value that quietly ignores withholding. Cliff starts from the number that matters — what reaches your bank account — and works backwards from there.
WHAT CLIFF DOES
• After-tax value, up front. See your unvested equity on paper and after estimated tax, side by side, with the split shown plainly: what you keep versus what goes to withholding.
• Every vest, mapped. Your next vest, the days until it lands, and what it's worth net — not gross.
• A what-if simulator. Drag the share price from −50% to +100% and watch your after-tax outcome move in real time. Find out what a downturn actually costs you before it happens.
• Multiple grants, multiple tickers. Track an initial grant, refreshers, and anything else, each with its own price and schedule — one-time or recurring (monthly, quarterly, annual, or a custom cadence).
• Vest reminders. Get a local notification before each vest so it never catches you unprepared.
• Live prices for public tickers, entered manually for private companies.

PRIVATE BY DESIGN
No account. No sign-up. No analytics. Your grants, salary and tax settings never leave your device — Cliff has no backend to send them to.
A NOTE ON THE NUMBERS
Cliff gives you estimates, not tax advice. It models federal, Medicare, Social Security and state withholding using rates you can edit yourself, so you can match your own situation. Your actual withholding and final tax bill depend on your employer, your full income and your filing status. Talk to a tax professional before making decisions about selling.
