The person’s total body-fat can make a tremendous difference to their body shape and health. Since muscle tissue is more compact than fat, any deposition of fat will cover a greater area than that of muscle. One of parameter that can be used to measure health status of a person is a body fat percentage, where it is defined as the total weight of the person’s fat divided by the person’s weight.
There are several methods to calculate body fat percentage, and usually the parameter for men and women also different. I choose two popular methods. The first method is Caliper method, which developed by A.S. Jackson, and M.L. Pollock in year 1985, that include weight in the calculation and the second method is developed by US Navy that include height in the calculation. You can read more information about Caliper method here.
Bill Payment Calendar

I created this bill payment calendar based on my weekly calendar spreadsheet. There are some requests about making an automatic bill payment reminder that will be displayed automatically in the calendar based on its recurring dates or days. Usually people have to mark or type their bill due dates on their calendar manually. Or, if you are using my monthly calendar, say if you have to pay once a month, you have to type 12 dates in each columns in setting worksheet to make the calendar display the reminder dates each month.
So, using the same approach with that monthly calendar, I created this bill payment organizer that will allow you to organize your bill payments with additional recurring day and dates adjustment formula. But, I choose to create it in weekly calendar first due to limitation concerns. If your due dates which share the same dates are more than five bills, I think this calendar will be your solution. If you want to have the bill reminder for one full month, you can print it four times with four different week period.

In financial, there are some standard value measurement that usually used to measure whether a new business or a new project is profitable or not. Some most common terms are ARR (Average Rate of Return), PP (Payback Period), IRR (Internal Rate of Return) and NPV (Net Present Value). All terms can be used at the same time and will also give you different result to value your investment. And this is the first tool of those four I created to help you calculate your investment profitability based on Net Present Value calculation, where it is defined as a difference between the present value of cash inflows and the present value of cash outflows.
I am not an expert in finance, but I know finance well because I am running several companies. I have some people who works for me to do all financial things where I have to use their financial reports when I made some business decisions.
You can use this NPV method if you positioned your self only as an investor that received a fixed amount of money in a short period. In my experiences, for a longer period of time, say more than 3 years, and with uncertain business risks, you should make a detail financial plan to justify your business plan.
