In a Traditional account, contributions are pre-tax (reducing your taxable income today), but you pay taxes when you withdraw in retirement. This defers taxes to later.

- b)Younger people pay less taxes
- c)Higher interest rates are available to younger people

- 5.You contribute 300 euros per month to your retirement account. What is your annual contribution?
Answer: 3600
euros per year. This is the first step in calculating your retirement growth!

Answer: early investor
- Calculate the annuity factor for 40 years at 7%: ((1.07)^40 - 1) / 0.07. Round to whole number. 200
- What is the early investor's final value? 1500 times the factor. Round to nearest thousand. 299000
- Calculate the annuity factor for 30 years at 7%: ((1.07)^30 - 1) / 0.07. Round to whole number. 94
- What is the late investor's final value? 3000 times the factor. Round to nearest thousand. 283000
- Who has more at 65: early investor or late investor? Type 'early' or 'late' early

- 15.You want to retire with 50,000 euros/year income. Using the 4% rule and employer 50% match, calculate your required monthly contribution from your pocket.
Answer: 500

- What is the annuity factor for 35 years at 7%? Use ((1.07)^35 - 1) / 0.07. Round to whole number. 139
- How much annual contribution reaches 1,250,000 euros? Divide target by factor. Round to nearest hundred. 9000
- How much is that per month? Divide annual by 12. Round to nearest euro. 750
- With employer 50% match, how much from YOUR pocket monthly? Round to nearest euro. 500
