Consequently, we will need to adjust for periodic payments in our fv calculation. Payment is not yet represented, but is very key here as we are paying monthly therefore, the interest will be applied to a new balance each time. Interest rate is represented by r number of payments, N payment, ?. Well, let's start going through the parameters. Pushing on, let's take a look at the FV() function which has this signature in Excel:įV(interest_rate, number_payments, payment, PV, Type)įrom the above, we can place a few of the parameters immediately into our simple future value formula:

«« do you see any potential issues with this code (hint: try values < 0)? The above would be placed after the calculation of the pmt variable from previous code sample.

Therefore, an easy way to update our above formula conditionally would be: if type equals "1", then divide by (1 + r) if type equals "0", then divide by 1 (or leave "as-is"). Mathematically equivalent is this formula: So continuing on the thought of the principal, its future value would reduce by one interest compounding or essentially compounded over one less payment (i.e., N-1):
The type specifies if the loan is paid at beginning of period or the end.Īside from these additional options, take a look at a sample scenario in spreadsheet:Ĭell to see an illustration of the change. The fv or future value establishes the amount of the loan or annuity that will be left after making all the payments specified by N or Nper as designated in Excel.
But it is a good starting point representing the formula when fv and type are both 0. With all that said, the above formula is the spreadsheet PMT() function at its basic level however, we know it is not complete as Excel, for example, allows for two other factors to the calculated payment amount: fv and type. However, for the remainder of the discussion, we will be looking at a mortgage loan paid monthly therefore, we will continue with 12 as the applicable divisor. This value should be expressed in whatever frequency the interest is compounded in like weekly or semi-annually as may be the case on some loans or annuities, especially in certain countries. Nota bene: r is a decimal representation of the per payment interest rate as suggested in the quoted text, but is not always monthly as stated. This monthly payment c depends upon the monthly interest rate r (expressed as a fraction, not a percentage, i.e., divide the quoted yearly percentage rate by 100 and by 12 to obtain the monthly interest rate), the number of monthly payments N called the loan's term, and the amount borrowed P known as the loan's principal c is given by the formula:

The fixed monthly payment for a fixed rate mortgage is the amount paid by the borrower every month that ensures that the loan is paid off in full with interest at the end of its term. Pure development sections are clearly identified as such and, additionally, code discussions within other sections are highlighted as "Code Example" for you to easily jump to (or over) when reading. For database developers, a brief overview of additional concepts for SQL based solutions will be shown with examples from MySQL (info: ) and MS SQL Server (info: r). Programmers using other languages can hopefully follow along using the Java explanations as pseudo code. This guide will go through the algorithm(s) for determining the formula of each, along with explanations on the nuances of the implementations of these methods within Excel or Calc (spreadsheets).įor all readers, there is a GLOSSARY of terms AT THE END OF THIS ARTICLE that you can refer to if you get to a term that is emphasized (e.g., bolded and italicized text) but unfamiliar to you.įor the developer types reading, the Java (info: ) programming language will be utilized to demonstrate the concepts in code. The correlation of the PMT, FV, IPMT and PPMT functions is their usage within fixed rate mortgage calculations therefore, you can research FRM (info: en./wiki/Fixe d_rate_mor tgage) for a greater understanding.

I have done a series of testing and validation on my understanding as well as actual programmatic reproduction of the PMT, FV, IPMT and PPMT calculations however, it is always prudent to fully test within your own environment with your business's common scenarios (use cases), making sure you get what you would expect before using any code shown as examples in a production environment.
