First, let's calculate your gross income per year:
Gross income per hour = $29/hour
Gross income per week = $29/hour * 40 hours/week = $1160/week
Gross income per year = $1160/week * 50 weeks/year = $58,000/year
Next, let's calculate the amount you save per year:
Savings per year = Gross income per year * 12% = $58,000 * 12% = $6,960
Now, let's calculate the employer matching contribution:
Employer matching contribution = Savings per year * 6% = $6,960 * 6% = $417.60
Next, let's add the spouse's contribution to the savings per year:
Savings per year = Savings per year + Spouse's contribution = $6,960 + $150/month * 12 months/year = $8,760
Finally, let's use this information to calculate the amount you will have accumulated in 50 years:
Amount accumulated in 50 years = Savings per year * (1 + 6.7%)^50 + Employer matching contribution * (1 + 6.7%)^50
Amount accumulated in 50 years = $8,760 * (1 + 0.067)^50 + $417.60 * (1 + 0.067)^50
This is the approximate amount you will have accumulated in 50 years of work, taking into account your gross income, savings, employer matching contributions, spouse's contributions, and average return on investment.
