A treasurer's report by hand: the statement and the reconciliation

Acres vs. square feet: comparing two lot listings by hand
2026-09-29 · 1 min read

One listing gives the lot in acres, another in square feet — they can't be compared until they're in the same unit, and the conversion is one multiplication or division away.

FIFO vs. LIFO cost basis: the same sale, two different gains
2026-09-27 · 2 min read

Which lots a sale is matched against changes the realized gain and can flip a sale between short-term and long-term — the shares sold never change, only which ones you say they were.

Refinancing into a longer term: check lifetime interest, not just the payment
2026-09-27 · 2 min read

A lower rate on a longer remaining term almost always lowers the monthly payment — it doesn't always lower what you pay in total, and the two numbers can point in opposite directions on the same refinance.

How an ARM actually resets: the three caps, in order
2026-09-26 · 3 min read

An adjustable-rate mortgage doesn't reset to whatever the index says — it resets to whatever survives the initial cap or periodic cap, and then the lifetime cap on top, applied in that order.

Pricing a powder-coating job: the real cost per part
2026-09-25 · 2 min read

Should you pay points on a mortgage? The break-even math
2026-09-24 · 3 min read

Paying upfront points for a lower rate only wins if you keep the loan past the break-even month — two payment formulas and one division answer it for your own numbers.

What a car really costs: total ownership, not the sticker price
2026-09-24 · 2 min read

The cheaper car on paper can cost more to own once depreciation, finance interest, insurance, fuel and servicing are added up — here's the arithmetic that catches it before you sign.

Is chasing a lapsed customer worth it? The win-back math
2026-09-24 · 3 min read

A win-back campaign is only worth running if the profit that customer represents beats what the campaign costs to send — five numbers and two multiplications settle it either way.

Comparing two loan offers: total cost beats monthly payment
2026-09-14 · 3 min read

Home insurance coinsurance: what being underinsured actually costs

A property policy can cut a claim payout — not just cap it — if you're insured below the coinsurance percentage the policy requires, and checking is one formula you can run before a loss happens.
