Four rules size every policy you'll ever buy.

Strip away the products and insurance sizing is four sentences. Here they are, with the Michigan specifics attached.

The four rules

  1. Liability = your assets. Auto BI, home liability, and umbrella should collectively cover what a lawsuit could take — tally it once and the limits pick themselves.
  2. Property = rebuild/replace cost. Homes to reconstruction cost (estimate it), contents to what refilling the house would cost, vehicles to the loan-vs-value math (hello, gap coverage).
  3. Life = income replacement. A serviceable shortcut: 10–12× income while people depend on you, adjusted for debts and college. Term until the math says otherwise.
  4. Deductibles = your emergency fund. Carry the highest deductible you could pay tomorrow without flinching — premium savings compound annually; deductibles are paid rarely.

Michigan footnotes

  • PIP is its own decision, tied to your health coverage — the six levels.
  • Toys count as assets and liabilities — the boat is both a thing to insure and a way to get sued.
  • Cottage inflation is real — lakeside rebuild costs run ahead of statewide averages.
Sizing is annual, not once. Assets grow, kids drive, roofs age, health plans change. Our renewal review re-runs these four rules automatically — that's what the agency is for.
