Netflix Premium at $24.99 plus two extra members at $9.99 each comes to $44.97/month. Three separate Standard plans at $17.99 each would run $53.97/month. Sharing wins by $9/month — but the margin has gotten thin.

We ran $200,000 of qualified business income through the calculator at $428,600 taxable income (MFJ) — $34,000 into the 2025 phase-in range. The W-2 wage limitation already cuts a non-SSTB business's deduction from $40,000 to $36,600.

A Qualified Charitable Distribution keeps donated RMD dollars out of your AGI entirely — which matters more than the direct tax savings once Medicare IRMAA and Social Security taxability enter the picture.

We ran a three-founder scenario (idea originator, technical co-founder, part-time investor-operator) through a transparent weighted formula — idea, time, capital, and experience — and the split moved meaningfully away from an even three-way default.

SECURE Act 2019 forced non-spouse heirs to empty an inherited IRA within 10 years. We compared equal-annual, lump-year-1, and lump-year-10 withdrawal strategies on the same balance.

IRC §1014 resets an inherited asset's cost basis to its value at death — erasing decades of unrealized gains for tax purposes. We ran the 15-year hold-vs-sell math on a real position size.

We ran a $5,000 international trip with a $250 Cancel-For-Any-Reason policy through the calculator — expected value turns positive above a 5% chance of cancelling, before even counting the medical-evacuation coverage most US health plans skip abroad.

The 2025 annual gift-tax exclusion is $19,000 per donor per recipient, $38,000 with spousal gift-splitting. We ran the 20-year math on a family with 3 children and 5 grandchildren.

We ran a textbook $7,000 backdoor Roth contribution through the calculator against a $93,000 old 401(k) rollover IRA sitting in the background — the pro-rata rule taxes 93% of the conversion, even though the new contribution itself was done correctly.

The 2025 federal exemption is $13.99M per person. Below that, zero federal estate tax. We checked why state exposure catches far more families — Oregon's exemption is just $1M.

We ran a $150,000 net-income freelance consultant through the calculator with a $70,000 reasonable salary — the S-Corp election clears even a $3,000/year compliance cost, because only the salary gets hit with payroll tax.

We ran a real 3-sibling scenario — a doctor, a teacher, and a freelancer — through equal, proportional, and hybrid cost splits. The 'fair' answer changes completely depending on which one you pick.

We ran a $300/year premium discount for raising a homeowners deductible from $1,000 to $2,500 through the calculator: breakeven is 0.2 claims/year (1 every 5 years), well above the III's ~1-in-12-year average claim frequency.

Two IRS tests decide it, and Social Security income doesn't count against the limit. We ran a real scenario: a daughter covering 70% of her mother's support, paying for adult day care so she can keep working.

We ran a $350K home at 90% LTV with a $200/month PMI premium through the calculator — a $300/month extra principal payment reaches the 80% removal threshold 10 months sooner, beating a modest investment-return assumption on the same money.
