How we calculate
formula · sources · cadence
Investment side: total_cost = tuition + months_unemployed × current_monthly_take_home + relocation_one_time + healthcare_gap_premium × months_unemployed. Return side: annual_delta = (new_role_p50 − current_gross) × (1 − marginal_total_tax) using DCEngine state-aware marginal rate. Break-even months = total_cost / monthly_after_tax_delta. 30-year NPV = sum of post-tax annual delta over 30 years, discounted at user-set rate (default 4% real), assuming a 1.5% real wage growth in the new role and a flat current trajectory. The math handles negative wage delta (career-shift to lower-pay role for non-financial reasons) by surfacing the negative ROI explicitly.

- How does this differ from bootcamp ROI calculators?
- Bootcamp ROI calculators (CareerKarma, Course Report) are tuned to a specific input — a coding bootcamp, ~$15K tuition, 4 months, software-engineer destination wage. This calculator handles any career change: RN to NP (graduate degree, 2–3 years, $40K–60K tuition), accountant to financial advisor (Series 65 + 6 months prep, $8K tuition), teacher to UX designer (self-taught + portfolio, $0–5K tuition), warehouse worker to electrician (apprenticeship, paid training but lower current wage). The math is identical — sum the costs, compute the wage delta, find break-even — but the inputs cover the whole landscape, not just bootcamp → SWE.
- What's a 'reasonable' break-even months target?
- Career-change literature suggests under 36 months is good, 36–60 is acceptable if the destination role has strong upside, and over 60 months is risky. The 36-month rule reflects empirical research on career-switcher regret (Pew Research Center 2023): switchers who broke even within 3 years reported satisfaction; switchers in years 4–7 of negative ROI reported 'starting to second-guess.' For mid-career switchers (45+), shorter break-evens matter more because remaining working years are fewer. For 25–35 year olds, even a 60-month break-even can pay off massively over a 30-year career.
- What's included in 'opportunity cost'?
- Four buckets: (1) Lost wages — months you're unemployed or in school not earning your current take-home, (2) Tuition or training cost, (3) Relocation if you're moving for the new role (movers + first/last/deposit + temporary lodging average $8–15K cross-state), (4) Healthcare gap — ACA marketplace silver plan median $470/month single, $1,580/month family for the months you're not on employer coverage. We add COBRA-equivalent for the first 18 months (typically 1.5–2× ACA) if you elect to maintain prior employer plan.
- Where do the BLS wage numbers come from?
- BLS Occupational Employment and Wage Statistics (OEWS, prior name OES) — the federal government's gold-standard wage dataset, surveying ~1.2 million establishments annually. Reports five wage percentiles (P10, P25, P50, P75, P90) plus mean by state, MSA, and 2- to 6-digit SOC code. May 2024 release covers ~800 occupations. We pull P50 by default for break-even (median realistic outcome), but you can switch to P25 (pessimistic) or P75 (top-of-cohort) in the calculator. Caveat: BLS surveys established workers, not new entrants — starting wages in the new role are typically 60–80% of P50.
- What discount rate should I use?
- 4% real (after inflation) is the conventional default — it approximates the 60/40 portfolio long-run real return and matches most NPV literature. Conservative: 6% real (you'd need the wage delta to clear a higher hurdle). Aggressive: 2–3% real. The discount rate matters more for long-payoff career changes (e.g., teacher → surgeon, 12-year payoff): a 4% rate gives roughly 60% of the year-30 wage delta as present value; an 8% rate cuts that to 40%. We default to 4% but expose the input.
- Does this account for wage growth in the new role?
- Yes, with a default of 1.5% real wage growth annually for the first 10 years (matches BLS CPS data for occupational mobility), then 0% real growth for years 11–30 (matches the empirical wage-curve plateau in mid-career). Your current role is assumed flat real (your wage indexes to inflation, no real growth) — a slight pessimism that biases the calculator toward 'switch is worth it' for high-growth destinations. If you have strong reason to think your current role has 2–3% real growth (early-career, in-demand skill), check the 'current role grows X%' override.
- What's the failure rate for career switches?
- Empirically, ~30% of career switchers in their first year reverse course (Bureau of Labor Statistics CPS 2023 — 'switchback' rate). The rate is higher (45%) for switches into licensed professions (RN, teacher, real estate agent) where the licensing exam is a significant filter, and lower (~22%) for self-taught switches into adjacent fields (e.g., marketer → product manager). Our calculator doesn't auto-discount for failure probability, but mentally apply a 25% haircut to the break-even-months estimate for high-licensing fields. Confidence in the destination role's market demand is the single biggest predictor of completion.
- How does state matter?
- Two ways. (1) Wage: BLS P50 for Registered Nurse is $86,070 nationally, but $148,330 in California, $74,630 in Texas. The destination wage drives the delta. (2) Tax: a $30K wage uplift in California is taxed at 9.3% marginal vs 0% in Texas — the after-tax delta differs by a third. Our calculator pulls BLS by your selected destination state and runs DCEngine state-tax to compute the after-tax delta. Stay-in-state shows the cleanest break-even; cross-state moves require modeling the BEA RPP adjustment too (use the cost-of-living comparison calculator for a sister-tool view).
- When should I switch even if the calculator says 'don't'?
- When the non-financial returns are large. The calculator computes financial NPV only. If your current role has high stress, low autonomy, or values mismatch — or if the destination role has a strong intrinsic match (passion, identity, autonomy) — a negative or low-ROI switch can still be the right call. Empirical research on job satisfaction (Gallup 2023) finds engagement explains ~25% of life satisfaction; pay above ~$95K explains 0%. The financial calculator sets a floor: if the negative NPV is over $200K (3–5 years of disposable income), think carefully. Below that, fit usually wins.
