Big-life decisions, run the numbers first.
The biggest life decisions get made on intuition because the calculators don't exist — and the ones that do exist are clickbait. CalcBold's Decision & Life calculators surface the real numbers underneath: runway months, cost of raising a child, sabbatical-impact on retirement, regret-minimisation framing. Honest framing, defensible math, no judgment about your choice — just the inputs to make it well.

Plug in your savings, monthly expenses, healthcare cost (don't forget — employer pays it now), expected income while off, severance, and your confidence level. Returns runway months after reserving an emergency cushion, with a verdict tier (GO / TIGHT / DON'T QUIT YET) and concrete next-action recommendation.

320K+/month - School ROI New
Back-to-School ROI Calculator
Tuition + lost wages (depends on full-time-quit vs part-time vs online) + loan interest vs post-grad salary uplift × your remaining career years. Returns total cost, total uplift, payback period, ROI %, and effective annual return — anchored against the 7% real S&P benchmark so you can see whether the investment beats putting the same dollars in an index fund.
140K+/month - Bootcamp ROI New
Career-Switch Bootcamp ROI Calculator
Tuition + lost wages × workMode + post-grad job search vs (post-grad salary uplift × landing-rate probability) × career years remaining. Returns expected ROI (honest about landing-rate risk) AND conditional ROI (if you land). Anchored to CIRR / SwitchUp audited placement data — not bootcamp marketing claims.
120K+/month - PhD vs Work New
PhD vs Work-and-Invest Calculator
5–6 years on a PhD stipend versus 5–6 years of compounding salary + investments. Plug in your current salary, expected stipend, PhD duration, post-PhD salary, raise rate, expected return, savings rate, and career horizon. Calculator runs full year-by-year wealth simulation for both paths and returns the net wealth gap, the year PhD wealth catches up to the work path (if it ever does), and lifetime earnings on each side. The post-PhD salary uplift compounded across decades is the actual lever — the stipend years are usually the smaller piece.
85K+/month - Sabbatical Cost New
Sabbatical Impact Calculator
What does taking 6-12 months off mid-career actually cost? Calculator returns BOTH the cash cost (savings needed) AND the long-term opportunity cost — lost wages + lost retirement compounding + re-entry salary penalty across remaining career. Most online sabbatical calcs show only the cash number; the lifetime cost is usually 5-10× larger.

7 tools- Time Wealth New
Time-Wealth Calculator
Every purchase is a trade — dollars for hours of your life. Most people compute their paid hourly rate and stop there, hiding the unpaid life-overhead (commute, chores, decision fatigue) that adds 30-50% on top. Plug in your take-home pay, paid hours, weeks, life-overhead hours, the item you're considering, and the rate you can hire help at. Calculator returns the item's cost in TRUE life-hours (not the rosy paid-rate version), your time-wealth ratio, and the buy-back-time arbitrage available when outsourcing rate < life-rate. Reframe spending as life-hours, not dollars.

75K/month - Lifestyle Trap New
Lifestyle Inflation Trap Calculator
Every raise has a choice: save it, or lift your spending. Most workers spend ~70% — and end up chasing a moving FI target. Plug in your raise rate, lifestyle-inflation rate, and current portfolio. Calculator runs year-by-year FI simulation under your scenario AND a zero-inflation counterfactual, then returns the years stolen from your financial freedom.
60K+/month - Regret Min New
Regret Minimization Calculator
Imagine yourself N years from now looking back — what would you regret more, having tried and failed, or not having tried at all? Plug in honest probability of success, upside if it works, downside if it fails, reversibility of failure, lookback horizon, and the dollar-equivalent annual regret of skipping. Calculator returns pure expected value (financial), regret cost of skipping, regret-weighted decision value, and a verdict tier that aligns dollar math with regret math. Low-probability + high-regret actions (career pivots, creative bets, asks-you'll-never-make-again) often clear the regret bar even when EV is mildly negative.

Frequently Asked Questions
The most common questions we get about this calculator — each answer is kept under 60 words so you can scan.
How are these calculators different from finance calculators?
Finance calcs answer 'how do these numbers compute?' (EMI, mortgage, retirement). Decision calcs answer 'should I make this choice?' — they take the same financial math and add the qualitative levers (confidence, risk tolerance, regret weighting, optionality) that turn a calculation into a decision. Verdicts are framed as 'GO / TIGHT / DON'T YET' rather than 'X dollars per month'.Whose research backs these?
Where defensible numbers exist, we cite them: USDA cost-of-raising-a-child report (annual), Bureau of Labor Statistics employment cost data, Stanford Marshmallow / behavioural-economics literature for regret-minimisation framings, World Bank cost-of-living indices for relocation, Kaiser Family Foundation healthcare data. Where research doesn't directly fit (most life decisions are personal), we surface the model assumptions inline and let users override.Aren't life decisions too personal for a calculator to weigh in?
The number isn't the answer — it's an input. A calculator that says 'you have 8 months runway' doesn't decide for you; it lets you stop wondering and start choosing. We build these tools because every life decision benefits from someone running the math first, even if the math is imperfect.Are the verdicts judgmental?
No. Every verdict tier maps to a recommended NEXT ACTION (build runway / extend horizon / re-run with new assumptions / proceed with confidence) rather than a moral label. The goal is decision support, not a sermon. Where the math is genuinely uncertain (parenting cost ranges, sabbatical career impact), we show the range and confidence band rather than a single number.
