# Mutual Fund SIP Returns Calculator

Use this suite of calculators to compute SIP and lump sum returns, compute SIP corpus and determine SIP amount needed for a goal. This represents an upgrade of my understanding of (a) excel functions and (b) the compounding process. The calculators also help illustrate a common error in converting monthly  returns to annual returns.

First some yada yada  (to borrow a phrase fromGoogle toolbar) if you don’t mind. Every since the blog got reasonably popular (for my standards) kind readers have called me a ‘Excel expert’ much to my embarrassment. Nothing is farther from the truth. The truth is  I use Excel because it is the only platform accessible to everyone. These calculators can be written in many platforms routinely used for physics research with much better efficiency. Truth is I am still unfamiliar with many Excel functions. I manage because, thanks to my training, I have realized that all of investment and amortization math stems from a single master equation. All one needs is high school algebra to manipulate the master equation to different situations. The Excel functions like FV, PV, IPMT etc. do just this.

Unfamiliarity with Excel features has certain disadvantages: Until yesterday I didn’t know that computing SIP returns can be done in a single step using an Excel function called RATE! I had earlier made a SIP returns calculator in a roundabout way resulting in a 5 Mb file with a minor bug (now corrected)!

The only saving grace is this version (post bug-fix) always returns the correct annual return. Most SIP returns and SIP goal calculators suffer from one flaw: If the assumed annual return is 12% they assume the monthly return is 12%/12 = 1%. This is incorrect. The correct monthly return is = (1+12%)1/12 -1 = 0.949%. You may think this is a small difference. However when computing SIP corpus for a long tenure and when computing annual SIP returns (long and short tenures) it can make quite a big difference.

That said the correct return can easily be computed from the result of the RATE function. The roundabout method I have used might be of some interest/use to enthusiasts, developers and planners.

So I present two versions of the SIP returns calculator:

Contents: versatile SIP corpus calculator, goal planner, SIP and lump sum returns (CAGR) calculator

Contents: investor version + my SIP CAGR calculator which directly returns the correct annual return

Thanks to Mr. Sukhvinder Sidhu for pointing out a minor bug in the description.

Our new book for kids: “Chinchu Gets a Superpower!” is now available! Most investor problems can be traced to a lack of informed decision-making. We made bad decisions and money mistakes when we started earning and spent years undoing these mistakes. Why should our children go through the same pain? What is this book about? As parents, what would it be if we had to groom one ability in our children that is key not only to money management and investing but to any aspect of life? My answer: Sound Decision Making. So, in this book, we meet Chinchu, who is about to turn 10. What he wants for his birthday and how his parents plan for it, as well as teaching him several key ideas of decision-making and money management, is the narrative. What readers say!
Must-read book even for adults! This is something that every parent should teach their kids right from their young age. The importance of money management and decision making based on their wants and needs. Very nicely written in simple terms. - Arun.
