Coast FIRE Calculator for Engineers
Engineering careers can vary across consulting, private industry, government, utilities, manufacturing and contract work. Enter your actual pay, hours and retirement benefits to compare work scenarios against the same Coast FIRE target.
Your Engineer Coast FIRE Plan
Enter your actual engineering salary, hours, benefits and retirement target.
Enter net take-home from your pay record rather than a national engineer salary average.
Your Engineer Coast FIRE Position
At age 60, your planned spending of $90,000/yr requires a target portfolio of $2,250,000. With 28 years of compound growth, $693,546 invested today will grow to that target with zero further contributions.

What If You Work Fewer Engineering Hours?
Reduced-Hours ScenarioCompare full-time engineering with a 32-hour (4-day), 24-hour (3-day), or custom schedule using your actual expected pay.
Workload Guardrail: The calculator measures hours and money only. It does not evaluate schedule flexibility, career progression, or work intensity.
Why Use an Engineer-Specific Coast FIRE Calculator?
An engineering career may include project deadlines, field work, consulting hours, bonuses, pensions or different work schedules. This calculator keeps those career variables separate from the Coast FIRE target so you can test a workload or employer change without relying on a generic engineer salary.
Engineering Compensation Is Not One Standard Salary
Civil, mechanical, electrical and other engineers work across consulting, manufacturing, utilities, government and other industries. Pay structures and retirement benefits can differ, so this calculator uses your actual take-home income and plan information rather than an occupational average.
Reduced Hours Change Cash Flow Before They Change the Coast Target
Changing work hours can alter current income and future retirement contributions. If retirement spending, retirement age and investment assumptions stay unchanged, the underlying Coast FIRE target itself does not change.
Frequently Asked Questions
Can I model going from 40 hours to a 32-hour engineering schedule?
Yes. Enter the actual take-home pay, retirement contribution and benefit changes for the 32-hour arrangement. The calculator should not assume that compensation automatically falls by exactly 20%.
What if I want to work only two or three days a week as an engineer?
Use the reduced-hours scenario with the schedule and compensation your employer or consulting arrangement would actually provide. The calculator can compare the resulting contribution path with the same Coast target.
How should I model engineering consulting when not every working hour is billable?
Keep total work time and paid or billable hours separate. Use the income you actually expect to receive rather than multiplying every working hour by a consulting rate.
What if I move from private engineering to a government engineering job with a pension?
Enter the actual take-home pay, contributions and pension estimate for the new role. The calculator can model the pension separately without assuming that all government engineering positions offer the same benefits.
How should I model bonuses or stock that are a large part of my engineering compensation?
Keep base and variable compensation separate. Use a base-only scenario and another with the user-entered bonus or investable equity value rather than treating future compensation as guaranteed.
Can I compare staying in engineering management with returning to a technical role?
Yes. Enter the measurable pay, hours, contributions and benefit differences for each role. The calculator shows their financial projections without assigning either role a stress or quality-of-life score.
Can I use the calculator if I expect to do occasional engineering consulting after leaving full-time work?
Yes. Keep irregular consulting income separate from the main employment scenario. If income becomes variable or self-employed, use the dedicated Freelance Coast FIRE calculator for detailed cash-flow modeling.
