Every investment account in the plan grows at one annual rate. Unless a rate is entered, that rate is the default below. It is the central estimate of a long-run average. Real years run above and below it; Monte Carlo shows how far, using the yearly spread that goes with each expected return (11.02% at the default).[1]
The rules
- Default: 6.35% a year. This is PWL Capital's expected return for a market-weighted portfolio of 80% equities and 20% Canadian bonds, from its 2026 planning assumptions.[2] For comparison, the same paper gives 6.92% for all equities, 5.73% for 60/40 and 3.58% for all bonds.[1]
- Nominal. The 6.35% includes inflation. With the default inflation of 2.5%,[3] the return after inflation is about 3.8%; see inflation and today's dollars.
- Net of fees. PWL's figures already subtract the management expense ratios of the funds that make up the portfolio, so the default is what an investor keeps before tax. A rate entered from a fund's gross performance would need the fee taken off first. See also net worth, which grows from this rate.
- Cash is separate. Uninvested cash earns the posted savings rate rather than the investment return;[4] see cash.
- Distributions. A fund or stock can pay out part of its return as dividends, interest or capital gains, or as return of capital. Each is taxed according to what it is,[5] and a reinvested distribution adds to the cost base;[6] see capital gains, dividends and foreign withholding tax.
- Fees paid separately. Investment counsel and management fees paid outside the fund are deductible in a non-registered account. Trading commissions are not; they adjust the cost base or the proceeds instead.[7]
What the engine does
- Applies the rate to every new investment account until a different one is set, and grows the balance through the year at that annual rate.
- Treats the rate on any account as its total return.
- Pays part of a non-registered account's return out each year, taxed that year. A diversified portfolio pays interest, dividends and some capital gains every year, and they are taxed in the year paid even when reinvested. The plan uses PWL's figures for its 80/20 portfolio: each year about 0.66% of the value in interest, 0.67% in foreign dividends, 0.51% in Canadian dividends and 0.45% in capital gains.[8] They are paid a twelfth each month and reinvested in the account, adding to its cost base, so the account's total return is the rate you entered and the rest of it is growth in price, taxed when sold.[9] Every non-registered account is taken to hold that mix; an account whose rate is below the total pays less, in proportion, and one at 0% pays none. Foreign dividends are taxed in full: the US tax withheld inside a Canadian fund never reaches your return as a credit. See dividends.
- Accepts other distributions and separately paid fees as dated events on a non-registered account.
What it deliberately does not
- It does not add a fee on top of the rate. The rate is already net, so a fee entered separately would be counted twice.
- It does not vary the return by year in a plain projection. Variation comes from the Monte Carlo and stress tests.
- It does not split a registered account's return into interest, dividends and gains, or deduct fees inside registered accounts such as the TFSA or the RRSP.
