Compound interest is a method used to calculate interest on an investment. It involves adding together the principal amount and the previously generated interest to determine the next interest payment. Unlike simple investments that earn a fixed amount of interest each time, compounding investments accumulate more and more interest, resulting in exponential growth of your assets over time.

Your RSUs vest on a schedule. Your brokerage shows you a table. Neither answers the question you actually have: what is this worth to me, right now, after taxes? Vestfolio is the private, dead-simple equity dashboard for employees. Add a grant in under a minute and see: • What's vested, what isn't, and what it's worth at today's price • An after-tax estimate of your unvested equity — the number that matters if you're weighing an offer or an exit • Exactly what vests next, and when — with optional reminders • What your equity becomes at any share price, with the what-if simulator PRIVATE BY DESIGN No account. No cloud. No analytics. Your grants, share counts, and values never leave your phone — only ticker price lookups and purchase receipts ever do. Delete everything with one tap, any time. Supports RSUs, ISOs, NSOs, and ESPP, public or private companies, standard and custom vesting schedules, cliffs, and multiple grants across employers. Every figure is an estimate calculated from what you enter. Tax estimates model United States withholding (federal, state, and FICA). Vestfolio is not tax, legal, or investment advice. Subscription required after a 3-day free trial: monthly or annual. Prices are shown in your local currency on the subscription screen. Cancel anytime in your Apple account settings.

Verdict
The clearest difference is in-app purchases: Calculator at none against Vestfolio's 2. Calculator also leads on device support (3 vs 1) and iOS requirement (14.0 vs 17.0). Vestfolio's advantage is ads (none vs shown) and update cadence (every 3 days vs every 3 months). On price there is nothing between them.
