# Daily Compounding Interest Formula Based On Two Different Rates?

May 29, 2014
What I am trying to do is to create a formula for the attached spreadsheet - that calculates the daily compounding interest based on the higher rate of the two rates for the first five years then after 5 years the calculation should only be based solely on the blocked rate.

I am trying to set up a budget for my self. Of course I am trying to make it as complicated as possible.

I have done searches online and that is how I found this forum. I am finding amortization formulas, but not what I want

Here is my question.

I have two fields, Mortgage and auto loan

I want to have a field that does a calculation for me.

I know following fields as an example making numbers up

Interest rate is fixed at 5.5%

Amount left on loan is 150,000

Loan is fixed at 30 years with 28 years left

I want to run a formula so when I make a monthly payment of 1000 dollars how much of that goes to interest, how much to principle (not to make this complicated even more, but let say that I have 200 escrowed which I am not sure if that has interest calculated on(I don’t think so as it is property tax?))

Same example for car loan.

5 year loan, 4.5% interest, payment 438 a month.

If i borrow Rs.50000/- at 7.25% interest compounding monthly, repayable in 4 quarterly instalments, when i put it in excel using pmt function for emi quarterly payment and ipmt for interest calculation at the end of the 4th quarter (i.e last instalment) the balance will not become zero it shows a balance of Rs.14.35 its due to interest compounding monthly, is there any formula in excel to overcome it?

attached the spreadsheet that I need help with in that same thread. Please check out the spreadsheet via: [url]

Here's my issue:

I'm trying to be debt free roughly around 10-11 years years based on my current plan. SO, what I am trying to do is figure out what I can do with my savings at 1, 2, and a 3 % rate of return in a savings account that is compounded monthly after that debt free point. My time frame for results are 5-10-15-and 20 years.

I have a problem calculating a total interest for an input period that has different interest rates. You can see the attached file: INTEREST.xls

I have used a function but the result comes out wrong. Can I fine tune it or do I have to change my method of calculating.

I am trying to work out a formula to calculate compounded interest rates.

I have a table that is 24 columns wide (months).

1 row that will have amounts input in to the columns (these will be different amounts)

I want to have a row along the bottom that calulates the compounded interest at a fixed interest rate on the total amount that is in the first row.

I have managed to do this using a table but surely there is a formula for this as the table can become very troublesome if the input amounts change.

I have a grid to determine interest rates. The are add ons to the rate that are dependent on two factors - the credit score and the Loan to Value percent or LTV, both of which are shown in terms of ranges (720-739, etc). See the screen shot below.

I have already written formulas for converting the score and LTV to the ranges as they appear on the sheet (ie, if you type in a score of 722, the formula converts it to the range of 720-739.

What I need to do is this - when the score and LTV are input and determine which set of add ons come into play, I need the sheet to take those add-ons, identified by an x next to it at the top of the page, and add them to the base interest rate, giving me the final rate. Again, see below to make this more clear.

I've thought of using VLookup, but I don' think that would be applicable here.

What's the best method, and can you give me an example of what a formula might look like?

Loan Level Pricing Adjustments

Base Rate 6.25 6.25

Credit Score 741 >740

LTV 60 740 Cash Out 0 0 0 0.25 0.375 0.375 n/a >740 Investment 1.5 1.5 1.5 2 2.5 2.5 n/a >740 2-unit 0.5 0.5 0.5 0.5 0.5 0.5 0.5 >740 3-4 unit 1 1 1 1 n/a n/a n/a

720-739 all -0.25 0 0 0 0 0 0 720-739 Cash Out 0 0.125 0.125 0.375 0.5 0.5 n/a 720-739 Investment 1.5 1.5 1.5 2 2.25 2.5 n/a 720-739 2-unit 0.5 0.5 0.5 0.5 0.5 0.5 0.5 720-739 3-4 unit 1 1 1 1 n/a n/a n/a

I need J22 to multiply based on years in B22 AND increase 5% for each of those years (compounding) after two years (excludes year 1 from 5% increase). In addition the cell needs to remain blank if D22 is blank. B22 = 1, then the stockprice needs to remain the same, and only increase by 5% after year 1.

Currently...

B22 = a number of years indicated by the formula: =IF(A22="","",DATEDIF(A22,I3,"y"))

J22 =IF(ISNA(VLOOKUP(D22,stockprices,2,FALSE)),"",VLOOKUP(D22,stockprices,2,FALSE))

Example:

If J22 stockprice lookup is $1000.00, and the number of years listed in B22 is 6, then the reported value in J22 needs to be $1494.40.

Some years ago I came across a formulae to calculate Daily Interest on a Building Society Savings account in the UK. I have used this since but find my calculations never work out the same as my BS, although to my advantage! It is =B3*B4/360*DAYS360(B5,B6,TRUE) Where:

B3=Capital

B4=Interest Rate

B5=Starting Date

B6=Finishing Date

For some reason the formulae uses 360/year and not 365/year. Using both still gives wrong answer.

I create this spreadsheet as a loan schedule using average daily balance method. (1/payment is constant, fortnightly 2/interest is 5.5% per annum)

In the interest column, at the beginning of each month ( when the day is 1) the interest will be added up from calculation of previous month daily balance.

My idea is that at interest column(let start at 1/08/2013) if (day(A49)=1, average the 30 or 31 cells above E49, 0).

I will manually make adjustment for February where 28 or 29 days applicable.

formula is needed to get excel to calculate all A rates seperate from B rates and C rates example 10 A rates @ 50.00 9 B rates @ 40.00 and 6 C rates @ 30.00 so although the rates could be mixed up (not following in any particular order the result which I would like to appear on a separate spreadsheet would be A = 500.00 B = 405.00 C = 180.00 then to get them to total up = £1085.00

A 50.00

B 40.00 then separate sheet with answer a 100.00 b 40.00 c 60.00

A 50.00

C 30.00

C 30.00

Never tried complicated formulas in Access and at a bit of a loss... What I am trying to do is calculate a utility bill based on stepped rated.

For example:

Usage up to the first 500KHW is billed at .067 per KWH

Usage after the first 500KWH from 501 to 999 is billed at .044 per KWH

Usage from 1000 up is billed at .0318

So if my usage was 1200 KWH...

((500 x .067)+(500 x .044)+(200 x .0318)) = 61.86

I was assuming it would require an complex "if" function to split the 1200 into steps and then calculate charges per step?

I want to calculate labour rates as follows:

06:00 to 18:00 std rate $10

18:00 to 06:00 night shift rate $15

I want to be able to type in the hours worked e.g. 11:00 to 19:00 and would expect 7hrs at $10 and 1 hr at $15.

We have agreed maximum rates with suppliers for certain services and I'd like to check that the rates they have invoiced fall below the agreed maximum.

I've attached an example of the data I'm working with. What I'm after is a formula that will cross check the details and rate charged on the 'Invoiced' tab against the three 'rate card' tabs and generate an output that flags any discrepancies. I've added a column called 'Validate' on the 'Invoiced' tab where I'd like this formula to go.

All the data should match with the exception of the shift which is listed as a description on the rate card but is a concatenation of the job role and an abbreviation of the shift (D = Days, N = Nights/ Saturday and O = Sunday/ Bank Hols).

I have a person who was paid £1000 pension pa for ten years. I've found out that the pension should have been split 50/50 with half increasing by 5% pa. Thus in year 1 total pension would be £1000. In year 2 the total pension would be £1025 ((£500 x 1.05) plus £500)

I know that in year 10 the total pension should be £500 (non increasing) plus £814 (£500 x 1.05 to the power of ten). My problem is how do I work out a formula which calculates the total arrears due in year ten? I'm thinking the arrears due after the ten years is £314 but something is telling me it's a lot more.

I use Excel 2007 , I created Interest calculator , on Daily basis , to caluculate interest , compounded quarterly.

But I want to make it compact , as d one I created is long enough.

A3 = Principal Amount

B3 = Date of Investment

C3 = Interest as on Date

D3 = Number of Days , amount Invested {comes out of formula set}

E3 = Rate of Interest

Now in F3 I want the Interest amount , compunded quarterly.

Some times NUMBER OF INVESTED CAN BE LESS THAN 90 DAYS TOO...then what ?

I am currently trying to create an excel spreadsheet where I would know how much interest I will pay in the next six months, since the balance changes every month I am not sure how to formulate the total interest paid with in a specified time period.

I currently can calculate the interest and fill in the below rows with each month but I would like to simplify the report so that I can add the Balance, Rate, Payment(2% of balance), and Time period and in another cell it will tell me how much interest I will pay in that time period. Bascially I would like to keep all the calculations in one row.

For example

Balance | Rate | Payment | Time Period | Interest Paid

$1,000 | 10.00%|$20.00 | 6 | $48.56

I am trying to calculate the effective annual interest rate earned on an investment and find the results are close but not really accurate. I suspect because I have not included the frequency of interest in my existing formula

r = n * nt root (A/P-1)

where;

r = the effective interest rate

n = the number of times interest is added per year

t = the total number of years

A = the current value

P = the original value

The 2 problems I face are;

1. Confirming this formula would provide the correct answer (need maths expert here) &

2. How would "nt root" (as in sqr root, but using the product of the years and frequency) be used in Excel

I have developed a financial calculator that asks the user for the "input date" which is used to record balances as of the input date. My interest calculation for the first year is based on the current date compared to the input date. For example, if the user is keying in a current balance of 10,000 @ 10% interest, and the "statement date" or "input date" is 12/30/2013, and the current date is today, 2/4/2014, then it should calculate interest for the entire year of 2014. It is not doing that. It calculates $3 interest.

But if input date is 6/30/2013 with current date of 2/4/2014, it seems to work OK. It calculates interest of $504 in that case. It appears to get messed up with the year transition between current date and input date. The formulas I have listed below appear to work fine except when the input date is 2013 for the year and the current date is 2014. The formula does not "see" that input date was last year. There must be a minor tweak to formula I am overlooking.

Cell C2 = Today's Date=TODAY()

Cell C3 = Input date (user keys in date in mm/dd/yyyy format)

Cell E2 = "translate input date to year format" =DATE(YEAR(C3),12,31)-C3

Cell E3 = Investment Rate

Cell G2 = yr 1 interest rate adjusted =(E3/1)*($E$2/365)

Cell C21 = Current Balance

Cell D21 = Interest Yr1 = C21*G2

I need the interest calculation to account for partial year accrual.

I would like to have an excel table that has 240 usable lines going horizontal (to the right) and vertical (down) from the starting number.

I need it to compound interest in both directions

240 is the total number of days per year I am trying to track

There should be adjustable starting amounts and compound interest

Be able to adjust the entered amount anywhere along the time line and it recalculate the amount from there on...

a person works for certain hours and get paid according to the hours worked either by day or by night or a mix of both. Day payment is $8 when worked between 08:00 and 19:59 , night payment is $12 when worked between 20:00 and 07:59. The excel cell are formatted as datetime with yyyy-mm-dd hh:mm , the function works fine in getting the time information and checking whether the whole work is all day or all night , yet the if-then-else statements for calculation seems to be wrong!!

examples:

start = 2008-01-01 09:15 , end = 2008-01-01 11:40 , all day as it is between 08:00 and 20:00 and cost = 8/hr = 19.333

start = 2008-01-03 21:05 , end = 2008-01-04 02:05 , all night as it is between 20:00 and 08:00 and cost = 12/hr = 60.000

start = 2008-02-02 19:00 , end = 2008-02-02 20:05 , cost = 9.000 as 1 hour day = 8.000 plus 5minutes night = 1.000

Function prod(st As Date, en As Date) As Double

Dim shour As Integer

Dim smin As Integer

Dim ehour As Integer

Dim emin As Integer

Dim stod As String

Dim etod As String

pday = 8

pnight = 12

shour = Hour(st)

smin = Minute(st) + shour * 60

If (shour >= 8 & shour < 20) Then

stod = "day"

Else

stod = "night"

End If

ehour = Hour(en)

emin = Minute(en) + ehour * 60

If (ehour >= 8 & ehour < 20) Then.................

I have the following scenario:

Cell A1 shows a specific value (pivot table value), but same A1 cell value might change if pivot table is refreshed.

So I am trying to automatically copy A1 value to another cell but I need to keep track of each value when pivot table is refreshed.

I have been researching about =Value formula, but it does not work properly since A1 cell reference will change each time pivot table is refreshed.

In order to calculate the annual IRR the formula should be =IRR(A1:A12)*12). The result is a 25.49% IRR. However, I've seen a formula that calculates the IRR in a different way. In this case, the formula is =(1+IRR(A1:A12))^12-1. In tis case the formula yields a 28.69% IRR. What exactly is the second IRR formula calculating? Is it compounding the monthly returns differently than the first formula? Which calculation is more accurate, and under what conditions would you use the first vs. the second formula (and vice-versa)?
