Purpose of the score
The OfferScope score is designed for early job-offer evaluation. It is not a tax calculator, credit decision, financial plan, or guarantee that an offer is good. The goal is to help a job seeker ask a practical question: after salary, taxes, rent, fixed costs, living costs, commute, and savings, does this offer leave enough room to accept with confidence?
The score is intentionally simple enough to explain. Most bad offer decisions happen because gross salary is judged before rent, taxes, and fixed costs are visible. OfferScope reverses that order. It starts with the money a user can probably use each month, subtracts the costs that are hardest to avoid, then evaluates the remaining flexibility.
Core formula
The first calculation is estimated monthly take-home pay:
Monthly take-home = annual salary x (1 - estimated tax rate) / 12
The second calculation is monthly flexibility:
Monthly flexibility = take-home pay - rent - commute - fixed payments - basic living costs - target savings
The third calculation converts flexibility and pressure ratios into a score. A positive monthly flexibility improves the score. A negative or very small flexibility reduces it. Rent burden, fixed payments, savings fit, moving requirement, and remote flexibility then adjust the result.
Weighting model
| Factor | Approx. weight | Why it matters |
|---|---|---|
| Monthly flexibility | 35% | Shows whether the offer works after required costs. |
| Rent burden | 25% | Rent is usually the largest fixed cost and hard to reverse. |
| Savings fit | 15% | An offer is weaker if it only works by eliminating savings. |
| Fixed payments and commute | 15% | Debt, insurance, transport, and required travel reduce resilience. |
| Offer risk adjustments | 10% | Moving requirement, remote flexibility, and assumptions can shift risk. |
Score bands
| Score | Signal | Typical interpretation |
|---|---|---|
| 90-100 | Strong | The offer appears comfortable after rent, fixed costs, and savings. |
| 80-89 | Good | The offer likely works, but benefits, lease, and tax details should be verified. |
| 70-79 | Workable | The offer can be accepted if assumptions are realistic and risk is controlled. |
| 50-69 | Tight | The candidate should negotiate, reduce rent, or adjust the plan before accepting. |
| Below 50 | Risky | The offer may create cash-flow pressure unless major assumptions improve. |
Rent burden thresholds
Rent burden is evaluated as rent divided by gross monthly income and checked again against estimated take-home pressure. Rent below 25% of gross income is usually flexible. Rent between 25% and 30% is often workable. Rent between 30% and 35% is a caution zone. Rent above 35% can be risky unless the candidate has high savings, low debt, strong bonus certainty, or a clear career reason to accept.
OfferScope does not assume the same threshold for every person. A high-tax city, heavy debt, family obligations, medical costs, or relocation expenses make a lower rent burden safer. A no-state-income-tax city, low debt, employer-paid benefits, or remote flexibility can make the same rent burden easier to handle.
Tax assumptions
The calculator uses an editable tax-rate field because tax outcomes vary by filing status, state, city, deductions, benefits, retirement contributions, bonus withholding, and payroll setup. OfferScope defaults are planning estimates only. Users should replace them with a payroll calculator, prior paystub, offer-specific benefits deduction, or tax professional estimate before making a high-stakes decision.
What the score excludes
The score does not fully price health risk, childcare, visa constraints, job security, equity liquidity, promotion probability, manager quality, relocation stress, or local housing availability. Those factors can change the decision. OfferScope is best used as a first-pass filter before deeper review. A high score does not make a bad role good. A low score does not make an excellent strategic opportunity impossible. It shows the financial pressure that must be understood.
Review policy
The methodology was last reviewed on May 25, 2026. Thresholds and assumptions should be reviewed when salary markets, rent levels, tax rules, or user behavior change materially. The product should continue to prefer transparent, editable assumptions over hidden precision.
How users should interpret the result
The score should be treated as a pressure reading, not a command. A score above 80 means the offer appears to have financial room under the assumptions entered. It does not prove the job is healthy, the manager is strong, or the company is stable. A score below 70 means the user should slow down and identify the pressure point. The right response may be negotiation, cheaper housing, relocation support, remote flexibility, or a different savings target.
OfferScope intentionally shows the inputs that drive the result. If rent is the problem, the user should see that. If fixed payments or commute are the problem, the user should see that too. This is more useful than a black-box score because job-offer decisions often become conversations with recruiters, partners, mentors, or friends. A transparent score can become a negotiation memo.
Quality control
Any future version of the calculator should preserve three controls: editable assumptions, clear thresholds, and a visible disclaimer. Editable assumptions prevent false precision. Clear thresholds explain why a result is comfortable, tight, or risky. The disclaimer reminds users that tax, legal, immigration, housing, and financial decisions require verification beyond a planning tool.
