Two salary figures do not describe two working lives. A career change may alter commute, insurance, retirement terms, leave, predictability and the amount of time you can control. Some of these can be modelled in cash. Others should remain explicit conditions rather than being assigned a made-up dollar value that lets a larger salary erase them.
Separate an offer from an assumption
Create two columns and mark every item as written, verbally described or unknown. Include pay, hours, location, start arrangements, benefit eligibility and any conditions attached to the offer. Do not treat an advertised possibility, such as flexible working after a review, as a guaranteed term.
Ask the appropriate employer contact for clarification where needed. This guide is not contract interpretation or legal advice. If a condition has significant consequences and you do not understand the agreement, obtain qualified advice before relying on it. A comparison sheet cannot make an uncertain promise enforceable.
Compare spendable cash consistently
Use your own reliable take-home estimates for both options, based on your circumstances. This site does not convert gross salary into net pay or calculate tax liability. Then list extra work-related costs that are not already reflected in those take-home figures: commute, parking, additional care or required personal equipment.
Avoid double-counting. If a health premium or retirement deduction has already reduced the take-home estimate, do not subtract it again as an extra cost. Use the offer-comparison tool to inspect annual ongoing cash and the effect of one-time transition costs in the first year. It assumes the same working-weeks convention for both options so you can isolate the entered differences.
Keep benefits visible instead of inventing a cash equivalent
Request plan documents or official benefit summaries and check when coverage begins, the employee cost, important coverage differences and any waiting arrangements. For retirement, check the employer contribution and which portion you expect to keep under the plan's vesting terms. Do not assume a headline match is immediately yours.
The retirement transition guide and health-insurance guide provide background for further research. The offer tool displays entered employer retirement amounts separately from spendable cash. It does not value medical coverage, calculate plan benefits or decide whether changing coverage is suitable.
Count the time the job actually takes
Compare expected working hours, commute and any routine preparation outside those hours. Clarify on-call expectations, travel and the difference between a policy and the team's usual practice. A nominally remote role may still require location-specific attendance or travel; ask rather than guessing.
The tool's cash-per-hour figure uses your entered total weekly time and working weeks. It is a planning ratio, not a legal hourly wage calculation or a statement about overtime eligibility. Differences in paid leave, intensity and schedule control still need their own discussion. Do not use a single ratio to erase a condition that makes the role unworkable.
Write non-negotiables before ranking
List the conditions that must be true for you to accept: a workable schedule, an accessible environment, a clear location arrangement or a financial floor. Keep preferences separate from genuine constraints. A higher cash result does not solve a non-negotiable requirement the role fails to meet.
CareerOneStop's interview guidance recommends asking about responsibilities and how performance is measured. Extend those questions to the actual conditions of delivery. Ask who sets priorities, how training is provided and what happens when the workload exceeds available time. No employer can remove all uncertainty, but specific answers are more useful than slogans.
Use separate columns for cash, time and conditions
Build a three-part comparison rather than one total score. In cash, include the entered ongoing amount and first-year transition effect. In time, record the working and commuting assumptions and what remains uncertain. In conditions, write the benefits and constraints you cannot responsibly price. Mark each item as confirmed or unresolved.
For a fictional comparison, option B could leave more ongoing cash but require a commute that conflicts with a care responsibility. The calculator may correctly show the cash advantage while the offer remains unsuitable under the stated constraint. That is not a contradiction or a reason to invent a financial value for the care conflict. It shows why the columns should remain separate. Ask whether the condition can be changed through a written arrangement; if not, keep it as a decision boundary rather than quietly removing it to make the larger number win.
Compare the first year with the ongoing arrangement
A transition can bring moving costs, equipment, a gap before pay or lost benefits. Enter real figures where you have them and keep unknowns visible. The cash-runway model can stress-test a shortfall; it does not assume a bonus, promotion or future raise will arrive.
Finish with a short decision note: confirmed advantages, conditions still unresolved, worst-case affordability and the question that could change your choice. If the offer only works when every uncertain item becomes favorable, you have identified a fragile scenario. The next step is clarification or a revised plan, not a more optimistic spreadsheet.
Evidence to gather next
- Use consistent take-home estimates and avoid double-counting deductions.
- Request written benefits and work-condition details.
- Write non-negotiable conditions before comparing cash totals.
A question worth separating
Should I add employer retirement contributions to monthly spending money?
No. Keep retirement contributions separate from spendable cash and check vesting and plan terms. The offer tool displays them separately rather than treating them as money available for current bills.
