Great for when you are in retirement too.

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.

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.

Great way to see the power of compounding

I use this app to crosscheck my calculations on quantitative models I build for the stock market. This allows me to check my compounding calculations in the model vs this approach. It is rock solid. If you are looking for a way to resolve a future value or "re-engineer" the duration needed, capital needed, rate needed to hit your numbers....this is the way to go. Very pleased.
