Hi. Excellent calculator for the Iphone, thanks. Is there an easy way of doing excalating annuities rather than having to work out the resultant rate?
Hi Clinton,
I’m not sure I’ve understood your question. Do you meaning growing annuity? I believe they are the same. In that case there is an option on the calculator for it.
Also it depends which version we are talking about, if you are on an Apple device (ipod, ipad, iphone) it works differently on the standard one that on the Financial Calculator Deluxe.
On Android there is only one version.
Call you tell me which device you are using and an example of what you want to achieve?
Above comment should be escalating annuities.
Hi, i bought this calculator about an hour ago. I also viewd the tutorials that u have posted here on your website! My app kinda looks different from the ont that you are using to teach. For PVM, Interest rate, i put all the info required but there is no go button, instead it has refresh button because of which i am unable to calculate. Can you please help me in this, i have my home work due on monday. Thanks for yoyr time and help!!
I guess you are talking about the “easy mode” and not the regular calculator mode. The refresh icon works the same way than the old “go” button. It will calculate the value next to it. So if you enter all the other info, it will calculate it correctly.
I think it’s better if you give an example, what are the other numbers are your putting in?
How much to purchase? Only the free version is in the android app store and no price is given when you try an in-app purchase. Also will this be charged in US$ ?
When you hit the in app purchase it displays information about the purchase and the price. About $ or not… that depends on your phone provider and google. Either way, it does not matter as far as i know, since you get charged your currency no matter which one is the end one.
English FAQ isn’t working. Unfortunately, it’s the only language I speak.
ups sorry, the link was broken when i moved the site.
try now, it should work
Hi. Its really nice calculator.
I seriously consider to buy it.
But, i use moto defy. So it is little bit slower than other calculator.
can i use it faster than now?.
Then i will buy it
i follow the NPV & IRR tutorial but unfortunately my IRR still remain unchange, it shown “NaN%” even i’d key in -25000 for 6 times. Any idea? Is it setting problem? Thanks!
your signs are wrong. You can only have 1 negative number to calculate the IRR, that’s just way the way IRR works.
Am finding it difficult to calculate effective yield. I cant get a value for (I/y). Using a different calculator I was able to but this is giving me an error message
what other numbers are you entering? pv, fv, pmt, etc… and what compounding are you using?
Hello Joaquin.
The beauty of a product is its user-friendly quality. I’ve just purchased your financial calculator app, and I’m sorry to report that your app is miles and miles away from being user friendly.
I have an old Texas Instruments calc. which has served me well since 1982! And it’s is as ever friendly as one can be. Based on an old mortage (in Canada) I had at the time: $3000 at 19.75% apr for 2 years, I paid 150,20$/month! Based on your calculator, I get a payment of 125$, or 127$ depending on the settings.
What gives? Am I wrong? Completely wrong?
Please advise soonest by return e-mail, or should I delete the app and forget all about your calculator?

Actually it works the same than the Texas instrument calculator, my guess is that your settings on c/y and p/y are wrongs since I get your same result for a canadian mortage.
It’s easy to test, just go to ‘easy mode’ and enter the loan amortization section. In there type 3000, 19.75 for interest and 2 years. Watch the monthly payments… by default is usually $152.32
Just tap on the correct interest compounding (i believe semi-annual or annual on canada).
If you want to get the same kind of results outside of easy mode, you need to set the c/y and p/y the same than on your texas instrument.
Hello Joaquin.
I on iPad 2 with iOs 5.0.1 have updated program Financial Calculator to version 2.9 and at me the program constantly hangs. It is impossible to change language, it is impossible to enter the data in Easy Mode.
It at me one or at all so?

Hi,
It’s not only you, a few people is having the same problem. It seems to happen randomly on iPad2. I’ve sent an update 2.9.1 to Apple and it should be out shortly (1 or 2 days). Hopefully that fixes it.
Thanks!
Let’s wait for version 2.9.1
Try the new update, version 2.9.1 is out already. Let me know if it fixed it
Purchased the calculator 2 days ago, froze on first use and have not been able use since, can you advise or will your upgrade deal with this problem, using IPad 2
yes it should. I just have no idea what Apple is doing since i’ve submitted it 5 days ago and it’s still not made public by them.
It should be out any time, it’s their call. It will be listed as 2.9.1
Try the new update, version 2.9.1 is out already! Let me know if it fixed it
Just now installed the new update on my iPad 1, but the calculator freezes in ‘easy mode’. Hopefully you can squash this bug! Best wishes.
Hi, yes it’s a bug on Apple’s side. It happens in only some of their devices. I’m in contact with them, meanwhile I rewrote the whole calculator to not use their api and asked them to do an expedited review and release. Version 3.0 should be out today or tomorrow.
try now, version 3.0 is out
My calculator is frozen and I cant use it !
Hi, yes it’s a bug on Apple’s side. It happens in only 10% of their devices. I’m in contact with them, meanwhile I rewrote the whole calculator to not use their api and asked them to do an expedited review and release. Version 3.0 should be out today or tomorrow.
I just bought the application. I was trying to find the interest rate, and added all the data (fv=1000, pmt=100, n=8, pv=1150), and got an ‘error’ msg. In a regular calculator it solves for interest rate, but here I couldn’t get it. Why? Is there a way to calculate this in the calculator application? I want the calculator mode.
Regards,
Shuli
It can’t solve it because you entered all numbers positive. I explained it on the tutorial videos.
On a financial calculator (any brand), you need to put cash outflows as negative and inflows as positive. You are saying you always getting money without putting anything, so obviously the calculator can’t give you a rate since you’ve never put any money. Since your fv is lower than pv, i’m guessing you want to invest the pv, so just put -1150 as a pv.
Then if you are going to receive the pmt, leave it as positive. If you are actually adding 100 to your account (outflow), then put it negative.

Hi, I am using the “easy mode” to calculate TVM. I have -3000 as PV 28000 as FV and -425 as PMT… When calculating the number of months I get 58.82 (in the easy mode app) months, but my text book gives an answer of 46.83. Could the answer I’m getting be part of a glitch? Or are months and Periods not considered the same thing, so months cannot be calculated on it?
Thank you,
Dave
Hi David,
I just tried with 3 different calculators and my result is correct. The possible options are that either your text book contains an error or that you are missing the interest rate (I/Y) and compounding info from the book.
Why isn’t there an Effective Annual Rate area on the calculator for interest conversion?
There is, hit “2nd” and then “ICONV”
Hi
I just download and install your Financial Calculator version 2.0 for Android. I installed in to my Android Tablet that use wifi so I download the apk file then install it from my SD card. I turned the app on and tried calculation, It turned out awsome so far yet I have one big question which you might find it rather silly yet it is important to me.
HOW can I TURN the calculator OFF????
pls help because everytime I use the calculator I’ll end up having to turn off my Tablet.
I tried to look from the picture of the calculator yet I couldn’t seem to find the ON/OFF or Exit button.
Pls Help thanks
Hi Nicole,
You have an option on “settings” to exit the app when you go to the home screen. It’s called “quit on exit”. It will shut it down when you leave the app 
this request was added actually from your question
Hi. I am using the easy mode and am trying to calculating semi annual cash flow. When I use 11% yield, 10 year and then 110 in 6 years, it works fine. So basically 0=0, 1=10, 2=10…5=10,6=110. NPV of 95,77 which is correct if using annual payments. If I want to calculate the NPV if using the same cash flow, but semi annually (0=0, 1=10…5=10, 6=110, and I change the P/Y to 2 instead of 1, but nothing changes… Your help is greatly appreciated
Hi Jon,
I don’t believe there is such thing as semi-annual on standard NPV cashflow calculations. What you do is just double the amount of time/payments or adjust the interest rate.
PLEASE!! Add a copy/paste functionality to this app, so that I can copy figures/solutions from the calculator directly to my notes or an email or an SMS without having to remember and retype it…..
THANKS A MILLION
Hi Devon,
I’ll see what I can do for the next update.
AgradecerE exponer un ejemplo, partiendo de los Flujos de efectivo esperados (v.g.: 60.000 – 72.000 – 84.000 – 97.000 y 112.000), durante 5 anios, a una tasa de descuento del 12%, para obtener la TIR (IRR) y el VAN (NPV). Thanks a lot.
El problema es que en un VAN (NPV) no puedes tener el primer flujo en positivo. Debe ser en negativo, ya que negativo significa que tu inviertes, y positivo que tu recibes.
Al poner tu primer flujo en positivo quiere decir que estas recibiendo dinero antes de poner nada de tu parte, lo cual seria maravillo pero la formula por algun motivo no se lo quiere creer
Your financial calkulator is not works currently on android 4.0.3. I press 8 or 3
or5,but on displey is : 8,88; 3,33; 5,55..
Hi there,
I’ve just released version 3.7 that should fix it for Android 4.x
let me know whether that did the trick
On android 2.3.6 it works very good without this problem
Hi, Joaquin.
I like your calculator. I have a casio FC 200V, but just wanted to have a basic thing in my phone too (though their interface and functionality are really different -yours is kind of hp-esque- I can work with your app problems-free).
So far, so good. Love the easy mode, it’s easy, for real. But I have a bug (or so I think) in the amortization mode (préstamos, en español). The numbers I use are large, and sometimes they just overwrite on themselves and I can’t see them properly. It happens usually on “paid interests” (interés pagado, en español).
I’m using an lg optimus black.
I can’t seem to get it to calculate a yield (i/y)
N 48
Pv 2000
Pmt 150
Should return the figure 86.86
It just returns a NaN
If you solve for payment using the 86.86
it works… and gives you the $150/month
But, the goal is too figure out yield on an
investment of 2000 with a payment of
$150/month for 48 months..
glad someone modeled a calc after the old
TI model… was sad to see them go..
Is there a fix for this missing yield calc?
Well this was answered on the FAQ area multiple times. Cash inflows are positive and outflows are negative. In your case you are putting everything positive (pmt and pv) which doesn’t make sense, that’s why you get an error. From what you are trying to do I guess you want both negative or at least one of them
Hope that helps!
Merry Xmas
Version 3.2 va a tenerlo de vuelta. Fallo de apple.
