WealthSim: Compound Interest

How much will you have if you invest every month? WealthSim answers in one line, shows how much of it you put in and how much interest adds, and helps you stay on track month after month. The calculator, My plan and saved scenarios are free. CALCULATE • Starting amount, monthly contribution, years and expected return, with sliders or exact figures • Your result first: "In 2046 you'll have…", split into what you contribute and what interest adds • Yearly bars that mark the year interest overtakes your contributions • Fees and inflation, with the result in today's money • Illustrative return assumptions for 5, 10, 20 and 30 years • Contribute monthly, every two weeks or weekly, raise it a set percent each year, or add a one-off amount in any year • Export the year-by-year table as CSV, next to the image and PDF MY PLAN • Turn any projection into a goal with a target amount and date • Log your real balance each month and compare it with the route • If you fall behind, see how much extra per month brings you back • Coast FIRE: how much you need invested today to stop contributing and still reach your goal, and the month you can stop • A reminder on your contribution day and a monthly summary after each check-in: months ahead or behind, your streak and the next milestone • Free small Home Screen and Lock Screen widgets with your plan • Upcoming milestones and an optional monthly reminder SAVE AND SYNC • Save, search and reopen scenarios • Private iCloud sync across your devices, no account needed WEALTHSIM PRO • 100 futures: your plan replayed 10,000 times with real US market years since 1928, so you see how often you reach your goal and the bad, usual and good outcome • The harvest: how long a withdrawal lasts with a fixed amount, the 4% rule or guardrails that cut or raise spending • What if…? Try +50 or +100 a month or one or two more years before you change your plan • Compare up to three projections side by side • PDF report and clean images to share • Medium and large widgets: your real balance against the route, the arrival date and 100 futures, with a Log balance button • Shareable milestone cards without the WealthSim footer • Unlimited plans • No ads The free version shows ads.
