How do you choose to save money over spend money?

Pay Yourself First!

  • Set aside money for saving before spending any money

  • Save then spend!

  • Creates a habit

  • Saving is not what is left at end of month

Why?


To successfully practice “pay yourself first”…

Set goals!

Goal-

End result of something a person intends to accomplish

Financial Goal-

Specific objectives to be accomplished through financial planning


What are you willing to give up to obtain the item you want to purchase?

This is a trade-off!

Trade-off - giving up one thing for another

Every decision you make involves a trade-off!

What is a trade-off to saving money for the future?

Being more financially secure in the future by saving money is a trade-off to spending money in the present


In order to choose saving money over spending money…

“Pay Yourself First”

To successfully practice this strategy…

Set financial goals

Examine trade-offs

Examine current spending


Simple Interest vs. Compound Interest

Simple Interest

Compound Interest

  • Interest earned on the principal investment

  • Earning interest on interest

Principal is the original amount of money invested or saved


Simple Interest Equation: Step 1

$1,000 invested at 7% interest rate for 5 years


Simple Interest Equation: Step 2

$1,000 invested at 7% interest rate for 5 years


Compound Interest Equations

There are two methods for calculating

compound interest

  • Single sum of money

    • Money invested only once at the beginning of an investment

  • Equal number of investments spread over time

    • Equal amounts of money are invested multiple times (once a month, once a year, etc.)


Compound Interest Equation – Single Sum

P (1+ r)n = A

Amount Investment is Worth

Principal (1 + Interest Rate)Time Periods =

$1,000 invested at 7% interest rate compounded yearly for 5 years

1,000 (1+ .07)5 = $1403.00


Compound Interest Equation - Multiple Investments in Equal Amounts

$1,000 invested every year at 7% annual interest rate for 5 years
