Very disappointing. Good app and very helpful. It doesn't calculate tax cost into the scenarios to compute real income ### 3/5 — No dark mode support *2023-07-08* Why? ### 3/5 — BASIC feature not present *2022-09-14* I like this calculator except for the fact that I have to put in monthly income and monthly expenses to figure the savings rate. There is no reason for this. I just want the option to put how much I save per month, I don’t need nor want to figure out all that extra math. **Developer response:** Thank you for your feedback. User use the app differently and many want to put in a lot of information. As a suggestion for your use case, you can just enter your montly savings rate as monthly income and do not enter any monthly expenses. That way the app does exactly what you want. Maybe you want to try the app again, I also added many new features in the last month. Would love to hear your honest feedback again. ## Most critical reviews (10 lowest-rated) ### 1/5 — FI CALCULATOR *2026-07-06* * ### 1/5 — Make FFCalc Great *2025-10-25* About 2 years ago when I first downloaded FFCalc it had a lot more features such as monthly income support, interest rate inputs, etc. Today when I wanted to create a new plan all this has disappeared and it is now asking for $2.99 fee per month. I’ll just put together my own spreadsheet and delete this app. ### 1/5 — Falsches Ergebnis *2022-10-07* Startkapital 1 Cent, jährliche Rendite 5 %, Laufzeit 2000 Jahre, alles andere auf null … Ergebnis nach 2000 Jahren 0€. Startkapital 1 €, jährliche Rendite 5 %, Laufzeit 2000 Jahre, alles andere auf null … Ergebnis nach 2000 Jahren 2,3 x10 ⁴². Schlecht programmiert. ### 1/5 — Not enough inputs to really calculate retirement *2020-06-07* Doesn’t account for inflation. Call calculate post retire rate of return different than Pre. **Developer response:** Thank you for your honest feedback. Over the years I improved the app significantly and now you can set many different inputs for each period. Would love to hear your feedback on the current version of the app. Maybe you would like to try it again. ### 1/5 — Crashed *2020-05-10* Chrashes **Developer response:** Hello, I found the bug, which occurred during saving the chart image to the photo library. If you want to, you can try the app again. ### 1/5 — No inflation? *2020-05-09* I’m thinking this app could be misleading. Not enough variables are included to make a safe retirement decision.... **Developer response:** Thank you for your honest feedback. Over the years I updated the app continiously and by now you can set many different variables for each period. So I think you could try the app again and I would love to hear your honest feedback again. ### 2/5 — Inaccurate calculations *2026-02-26* There is a flaw in this app in that it is using my salary to calculate my monthly savings, which when annualized equals my salary. This is not an accurate or dependable application and needs to be fixed. ### 2/5 — Very basic with few options *2021-11-14* Good premise, but no ability to change the earn rate during retirement or even before you retire to get ready for it. ### 3/5 — Retirement calculation with inflation not correct *2024-12-09* I like the app but there few issues while calculating inflation for the retirement period. 1) While calculating retirement expenses system should multiply expenses x (1 + inflation) for future expenses. 2) There should be option of adding income during retirement as sometimes we get passive income like agriculture or house rent etc.. ### 3/5 — Good app, but ridiculous pricing *2024-06-01, version 2.4.1* Way too expensive ## Most praised reviews (10 highest-rated) ### 5/5 — Easy to use *2026-06-23* This app is awesome!! ### 5/5 — Great app *2024-12-24* It's a great tool, love the ability to add multiple periods. However the numbers don't match my calculations, so it needs more clarity around how the compounding is figured: - compound interest seems to be off by about -1.14% for a simple $0 expenses no inflation 2yr plan. It varies with years. - unclear how often inflation is figured (monthly?) - unclear if contributions are calculated at the start of the month or the end ### 5/5 — Awesome App *2024-07-20* Awesome App, it’s lets you do almost everything for free. I was so impressed I bought the full version to support the developer. ### 5/5 — Superb app *2024-03-24* This app is the best I’ve found as it allow you to build multiple investment scenarios taking into inflation, growth rate and one off investment or expenditure Most finance apps of this nature are far too simple Also love the real-time graphs that clearly illustrate if your investment/ retirement strategy will work Support is super helpful too and respond really quick I would highly recommend this app if you want to plan your retirement savings and wish to quickly model various financial scenarios ### 5/5 — simple to understand and use *2023-12-11* price is affordable too ### 5/5 — Nice straightforward app! *2021-08-15* Does almost exactly what I was looking for, without annoying ads. Well done!! ### 5/5 — FI CALCULATOR *2021-05-23, version 1.3* FI CALCULATOR IS VERY GOOD APP TO WORK OUT HOW LONG IT WILL TAKE TO REACH FINANCIAL INDEPENDENCE. ### 5/5 — Easy to use, fab App *2021-02-07* Downloaded today and within a min or two was understanding different scenarios that could be my future. Highly recommend for looking at what your savings could be and/or onward planning for retirement. Excellent! ### 5/5 — Beste FIRE App *2020-04-05* Vielen Dank für diese App! Habe fast alle getestet. Diese ist die beste ihrer Art. Seit dem Update nochmal deutlich besser und hilft nun auch die Szenarien nach dem erreichen der Fire Number zu prognostizieren. Sehr gut! ### 4/5 — Klasse Umsetzung mit Potential nach oben *2024-10-30* Lieber Entwickler, besten Dank für die tolle Umsetzung, gefällt mir sehr gut. Weiter so und vielen Dank! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
