A fictional comparison of spendable pay, commuting, benefits and time, with explained answers.
Free guided activity · 35 minutes · Ages 15 and up
Before you start: Monthly budgeting and multiplication.
Learning goal: Compare consistent pay estimates and job-related costs while recognizing benefits that are not spendable cash.
Preparation: Paper, pencil and calculator. Allow one shared screen for the linked tool, or use the printed exercise offline. Fictional figures are for practice.
Compare monthly take-home estimates using the same assumptions. Annual salary divided by twelve is gross monthly pay, not take-home pay. Check which employee deductions are already included before subtracting them again.
Open the job comparison tools →Compare travel, parking, childcare changes and relocation costs. Track commute time separately from cash. Paid leave, schedule control, training and job stability may matter even when they are hard to price.
Explore salary and budgeting calculators →Read each offer’s benefits documents. Separate accessible cash from employer retirement contributions, and check eligibility and vesting. Avoid treating every dollar of an employer’s reported benefit cost as a dollar you can spend.
Explore wages and purchasing power →Fictional monthly take-home estimates after the same deduction categories: offer A $3,900, offer B $4,100. A requires $100 commuting costs; B requires $400. B also requires 20 extra commuting hours per month. Employer retirement benefits have not been converted to cash.
Which offer leaves more after commuting costs?
How should the extra 20 hours be handled?
What remains unknown before deciding?
Exit ticket: Explain one result in your own words and name an assumption that could change it.
Try the worksheet first. These answers explain the reasoning, not just the result.
A leaves $3,800; B leaves $3,700. A leaves $100 more monthly despite the lower stated take-home pay.
Record them explicitly as time. You can choose a personal value for comparing tradeoffs, but subtracting that value does not change the actual cash in your bank account.
Health coverage and out-of-pocket costs, retirement eligibility and vesting, schedule, paid leave, job stability and career development. Either offer could be preferable once these are understood.
Next week: name one cash cost and one noncash benefit that could reverse your preference, and explain why.
For a younger learner, work through the first calculation together. For an extension, change one assumption and defend the new conclusion.
