Trade School ROI Calculator
Calculate return on investment (ROI) for trade school vs 4-year college. Compare total costs, graduation rates, time to degree, starting salaries, and lifetime earnings for electrician, plumber, HVAC, welding, nursing, and other skilled trades. Determine payback period and break-even point with 2025 tuition data and job market statistics.
A1c To Glucose Calculator
Convert A1C (HbA1c) percentage to estimated average glucose (eAG) using ADA formula: eAG = 28.7 × A1C - 46.7. Input A1C value (4.0-15.0%) and instantly see eAG in mg/dL and mmol/L, diabetes risk category (Normal <5.7%, Prediabetes 5.7-6.4%, Diabetes ≥6.5%), target A1C recommendations, glucose reduction needed, and months to target. Includes 4 view modes: Calculator, Analysis (risk assessment), Ranges (ADA guidelines), and Guide (lifestyle management). Essential for diabetes monitoring, treatment adjustment, and blood sugar control optimization.
Allowance Calculator By Age
Age-based allowance calculator using $1-per-year formula. Calculate weekly/monthly/yearly allowance by child age (4-18), include chore bonuses ($0.50/chore), adjust for regional cost of living (80-130%), apply 80/20 savings split, get age-appropriate chore lists, financial literacy milestones, hybrid chore-based vs unconditional allowance models, and transition strategies to teenage monthly budgets.
Anion Gap Calculator
Calculate serum anion gap (AG) and albumin-corrected anion gap using Na⁺, Cl⁻, HCO₃⁻ electrolyte values. Formula: AG = Na - (Cl + HCO₃), normal range 8-12 mEq/L (traditional) or 3-11 mEq/L (modern without K⁺). Input sodium (135-145), chloride (96-106), bicarbonate (22-28), albumin (3.5-5.0 g/dL) and instantly see standard AG, corrected AG (adds 2.5 mEq/L per 1 g/dL albumin below 4.0), diagnostic category (Normal/High AG metabolic acidosis/Low AG), differential diagnosis (MUDPILES mnemonic), and compensation analysis. Essential for ICU/ER acid-base disorders, DKA, lactic acidosis, renal failure, and toxic ingestions.
Baby Formula Calculator By Age
Baby formula calculator by age using AAP 2.5 oz/lb guidelines. Calculate daily formula needs (max 32 oz), determine feeding frequency by age (8x newborn → 4x at 6+ months), compare formula costs (powder $0.12/oz vs concentrate $0.18/oz vs ready-to-feed $0.30/oz = $1,200/year savings), get safe preparation guides, water safety rules (boiling, Cronobacter prevention), storage times (2 hours room temp, 24 hours refrigerated), transition timeline (solids at 6 months, whole milk at 12 months), special formula options (soy/hypoallergenic), and WIC cost-saving strategies.
Backdoor Roth Calculator
Calculate 2025 backdoor Roth IRA contributions: Convert $7,000 traditional IRA ($8,000 if 50+) to Roth via non-deductible contribution + immediate conversion. Estimate pro-rata tax rule impact (taxable portion = pre-tax IRA balance ÷ total IRA × conversion), conversion tax liability (ordinary income rate 10-37%), 5-year rule for qualified withdrawals. Ideal for high earners exceeding Roth income limits ($161k single, $240k married 2025). Avoid penalties, track Form 8606 (non-deductible basis), calculate break-even vs taxable account.
