# Confusion on counting years in Time value of money

I am really getting confused when calculating the number of periods in TVM,
any advice on how to tackle that ?

Do you mean when using a calculator or just in general?

in general how to count the periods especially when there is annuity due

Admittedly, this is something a lot of people still struggle with, including myself.
The best way to do this is to literally draw out a timeline with pen and paper, and label each tick on the timeline with what year.

Hi Firas1978,

Thatâ€™s quite understandable. While it may seem complex, a solid grasp of Time Value of Money (TVM) is fundamental to understanding other financial concepts. In my opinion, progressing without a firm understanding of TVM would be quite challenging.

In response to your request, I strongly recommend building and experimenting with TVM models using Excel. Start with a case study from your curriculum or any relevant textbook and create your own TVM model from scratch. To deepen your understanding, avoid using Excelâ€™s built-in TVM functions initially. Instead, manually calculate TVM components to gain a better grip on the concepts.

Also experiment with changes in:

• Beginning/Ending of Period
• PMT (Payment)
• PV (Present Value) and FV (Future Value)
• Number of Periods
• Discount Rate

Focus first on the mathematical concepts and relationships. Once you have a solid grasp on the math, you can then apply it to financial contexts. Remember, the goal is to internalize the concept (as the optimal time to answer each number is ~1.5 min)This approach worked well for me and took about a week.

Hope this helps!
