The dollar-anchored framework

The standard framing breaks when your income changes

Most retirement advice asks you to save a percentage of your income — 10%, 15%, sometimes 50% if you want to retire early. The trouble: as your income changes, the dollar amount you actually put away changes too. A 15% savings rate on $60,000 of income is $9,000/year; the same 15% on $75,000 is $11,250. Your savings rate stays "the same" but the dollars hitting your investment account drift.

Worse: the percentage-of-income framing makes the destination feel hazy. You're saving "enough" relative to income — but enough for what? Most calculators answer "enough for some assumed retirement spending at some assumed age" — assumptions that aren't really your assumptions.

The reframe: lock the dollar amount, let the percentage fall out

The dollar-anchored framing flips the relationship. Start with two numbers:

1. How much do you want to spend per year in retirement? (your annual retirement income need)
2. When do you want to retire? (your target age)

From those two numbers and a reasonable assumption about safe withdrawal rates (3% to 4% is the canonical range), you can compute the dollar amount your portfolio needs to hit by your target age. That's your dollar target. From there, you work backward to the dollar amount you need to save each year — not a percentage, a dollar number.

Once you know the dollar number, your savings rate becomes the falling-out variable. If you make $60,000 this year and need to save $12,000, that's 20%. If you make $75,000 next year and still need $12,000, that's 16%. The percentage drifts; the dollar amount — and therefore the destination — stays locked.

Why this works for non-experts in particular

Non-experts get tripped up by percentage-of-income framing because the destination is invisible. "Save 15% of your income" doesn't tell you when you're done. Dollar-anchored framing makes the destination concrete: you're done when your portfolio hits $X. That's measurable. You can check it. You can plan around it. And if a salary raise gives you slack, you can put the extra dollars into "saving faster toward the same destination" rather than "increasing the lifestyle baseline that determines your destination."

What the calculator does with this

The Simple Calculator takes your four numbers (age, target age, current savings, annual spending), computes the dollar target using the most-conservative 3% SWR assumption, and shows you whether your current savings rate projects to that target by your target age. Three states:

• Comfortable — projected ≥ required, with margin
• Tight — projected is within 10% of required (no buffer)
• Short or Critical — projected falls below required

If you land at "Short" or "Critical," switching to Advanced lets you add the things the worst-case anchor doesn't model: CPP/OAS, partner income, tax-aware withdrawals, expected inheritance. Most Canadians who see "Short" in Simple move to "Tight" or "Comfortable" in Advanced — the worst-case is genuinely worst-case.
