I like to use it to project what my 403b, Roth IRA, or my kids 529 plans will be worth years down the road. ### 5/5 — Hands down the best and important accessible financial future value calculator out there *2024-10-13* Aside from common sense Compoundee is the one indispensable financial planning tool to ensure your financial future is on track and obtainable. It’s sorta like use it or lose it. Thank you Compoundee. ### 5/5 — Hands down the best financial future value calculator out there *2024-07-13* Aside from common sense Compoundee is the one indispensable financial planning tool to ensure your financial future is on track and obtainable. Thank you Compoundee. ### 5/5 — Still the best! *2022-05-10* This app is still the best of its kind. I just wish the developer would give the UI a little love. I would gladly pay for an update. But I’m afraid it has been abandoned. There are no functionality issues despite not being updated for years, however. ### 5/5 — Investing *2020-03-18* Use this with all my younger family members when talking about budgeting and investing. Makes one think about what am i spending money on now and what would i have if I invested it instead. Tells you how much is your actual cash versus the interest and what the future value will be worth after inflation. Use it often. ### 5/5 — Excellent *2020-02-22* Great app and easy to use!! ### 5/5 — REAL FVM APP *2020-02-11* Most FVM apps don’t allow negative additions, ie. you are living off your investments. This one does. Very well formatted as well. ### 5/5 — Great for when you are in retirement too. *2020-01-26* I use this app as a retirement planner and I’m already in retirement. I put in an annual negative contribution and it tells me how long me money will last, considering the interest rate I am using. You can also put in inflation and/or taxes and get a result from those inputs. You don’t have to though. I have used this app for many years, both before retirement and after. It is the best. I like it much better than the software the PFP’s use. The Marco Polo software they use is a bit too mysterious for me. ### 5/5 — Does what it should reliably *2019-07-10* I’ve had this app for years. It reliably computes compound interest as it should without having to go to an online calculator. ### 5/5 — Great n Simple *2019-02-11* Does what they publish. Simple to the point. Better than the old spreadsheet or pencil paper planning. I concur with another reviewer Edward8 ## Frequently asked questions about Compoundee ### What does Compoundee do?
