YIELD — Compound Calculator

Plan your investments and see how compound interest works over time. Calculate, track real portfolios, and stress-test them against past crises. YIELD is a compound interest calculator built for people who want numbers they can trust, not a wall of ads. Everything runs on your device. No account, no sign-up, no data collection. CALCULATOR Set your starting deposit, rate, term and regular contributions, then watch the balance grow year by year. Contributions can be daily, weekly, monthly, quarterly or yearly, at the start or the end of each period. Results update as you move the sliders, with a chart and a full breakdown of deposits, interest and total return. COMPARE SCENARIOS See conservative, realistic and aggressive returns side by side on one chart, so you know the range instead of a single optimistic number. THE COST OF WAITING Find out what one more year of hesitation actually costs you, in money. SAVE YOUR CALCULATIONS Save a set of parameters, give it a name, and bring it back with one tap. Reset to defaults whenever you want to start clean. RULE OF 72 A quick estimate of how long it takes your money to double at a given rate. MORTGAGE VS RENT Compare buying and renting over the same period. Down payment, mortgage term, rate and rent are all adjustable, and the app tells you which option comes out ahead and by how much. PORTFOLIO TRACKER Track what you actually hold. Add positions, record purchases, and see the total value, profit and return across all your portfolios. Import and export your data as a file so it stays yours. CRISIS SIMULATOR Apply the real drawdowns of past market crashes to your own portfolio and see what would have happened. A useful reality check before the next one. PRIVACY AND SECURITY Lock the tracker with a PIN or your fingerprint. Nothing leaves your device, so there is nothing to leak. No analytics, no tracking, no ads inside the app. REMINDERS Optional notifications to update your portfolio, so tracking does not quietly stop after two weeks. SHARE Turn any calculation into a clean image and send it to whoever needs to see it. 16 LANGUAGES English, Ukrainian, Russian, German, French, Spanish, Polish, Portuguese, Chinese, Japanese, Arabic, Hindi, Korean, Vietnamese, Italian and Turkish, with full right-to-left support for Arabic. The core calculator is free forever. YIELD Premium removes the limits on saved calculations and portfolios. YIELD is an educational tool. It does not give financial advice and does not predict returns.
