A Registered Education Saving Plan (RESP) is an effective way of saving for the cost of a child’s post-secondary education. The maximum contribution allowed for each child within an RESP is $50,000. The government matches contributions with Canada Education Savings Grants up to a maximum of $7,200 per child. The growth on the savings is tax deferred and the accumulated assets are withdrawn during the period the child attends post-secondary education.
We examine the potential of the RESP to meet the future costs of higher education given the recent history of tuition fees increasing above the general rate of inflation.
Start with the end in mind
Our focus is to assess the future cost of post-secondary education and whether savings through an RESP is likely, with current expected capital market returns, to cover these costs. We examine different investment strategies, different savings periods and the impact of investment management fees. This is an area that has not received much attention because the amounts are small compared to many investors’ total investment capital. In addition, it is more challenging to design a portfolio to meet a specific liability over a fixed time period than to seek long-term capital growth.
Clear thinking about objectives drives the investment strategy. Investors who attach a high importance to maximizing the potential final value must shoulder the risk of a shortfall. Investors who want to avoid downside risk must be prepared to invest more to achieve the same outcome to compensate for the lower return. Understanding these trade-offs is the motivation for constructing our analysis.
Cost of post-secondary education
What is a reasonable estimate of the future cost of a university degree? A 2013 BMO study estimated the total current cost to be $60,000, including tuition, residence, meals and books. A frequently cited report from TD Canada Trust suggests that the annual increase to a student budget over an 18-year period is in the 2.9% to 3.5% range – well above the current rate of inflation. If we apply the mid-range of the TD estimate over the next 20 years, this would suggest a total cost of $112,653 in 2034. The BMO report estimates a cost in excess of $140,000 over the next 18 years. All these estimates are in future dollars.
These figures have attracted criticism. Some commentators feel that the banks are not impartial sources of advice and may be inclined to inflate savings requirements. Others point out that while it is true that tuition costs have outpaced the rate of inflation in the past, this is not sustainable indefinitely. Yet the most recent data on tuition costs from Statistics Canada shows a 3.3% increase in 2013-2014, following a 4.2% rise in 2012-2013. In comparison, inflation (as measured by the Consumer Price Index) was 1.3% between July 2012 and July 2013. Our approach is to take the average of the latest Statistics Canada data of 3.3% and PWL’s own estimate of general inflation of 2% to yield 2.65% as our estimate of the increase in total educational costs, recognizing that it is a blend of tuition costs and general student living costs.
Starting with the BMO estimate of current education costs of $60,000 and inflating it for 20 years at 2.65% yields a cost in 2034 dollars of $101,234. To enable comparisons over different time horizons, it is convenient to convert 2034 dollars into 2014 dollars, which is $68,127, a 13.5% real increase.
Asset allocation decision
Having established a reasonable funding target, how successful are different asset allocation strategies?
We first discuss a 100% fixed-income strategy; then we’ll consider a 100% equity strategy and finally, intermediate asset allocations.
100% fixed income
If we could invest all the funds in the first year we could simply buy a bond that matures in 20 years. In the first year the initial deposit would be $50,000, which would attract a single government grant of $500, giving a total investment of $50,500. No further grants would be paid but this strategy maximizes the benefit of the tax-free compounding.
In our model we assume a single payment representing the total cost of a 4-year degree rather than staged payments over a 4-year period. We assume a maximum investment period of 20 years but also look at a 10-year period.
Currently, a Canadian investment-grade 20-year bond yields 4.0%. The total maturity value after 20 years of an initial investment of $50,500 is $74,225 (in 2014 dollars), which exceeds our target of $68,127. The main risk to this strategy is unexpectedly high inflation that erodes the spending power at maturity.
In practice, most young families are unable to make a $50,000 lump sum investment when their child is born. This leads us to construct a more realistic regular payment schedule. In Table 1 we construct a series of deposits that maximizes the government grant over both a 20-year and 10-year period. We assume the 10-year schedule starts 10 years later than the 20-year schedule and finishes on the same date.
Table 1(a) 20-Year Deposit Schedule
|Year||Deposit||Grant||Cumulative Total Deposits|
Table 1(b) 10-Year Deposit Schedule
|Year||Deposit||Grant||Cumulative Total Deposits|
A fundamental principle of investing is to avoid risks that you do not get paid for. With this in mind, the best fixed-income strategy is to buy a bond every year that matures at the target date of the RESP. Thus, considering the 20-year investment schedule, in the beginning of Year 2 we would purchase a bond maturing in 19 years, and so on. Buying bonds that mature before the 20 years exposes the investor to reinvestment risk; buying bonds that have a maturity longer than 20 years exposes the investor to interest rate risk. Matching the maturity of the bonds with maturity of the RESP makes us indifferent to what interest rates might do over the intervening period.
Since we do not know future bond yields, we use the simplest model of taking the current yield curve and construct a straight line between the cash yield and the 20-year bond yield. Expected returns and standard deviations are based on PWL estimates using an equally weighted blend of historical performance and current market conditions. We use a Monte-Carlo model to simulate the volatility in returns and assess the downside risk. The model uses a normal distribution, which underestimates tail risk in equity market returns. So, consider our estimates of downside risk to be understated. See Appendix A for further details of the simulation model.
The model predicts a range of outcomes rather than a single value, reflecting the uncertainty around future bonds prices. The average value, as represented by the median or 50th percentile, is $56,406 with less than 1% probability of reaching the desired outcome of $68,127.
Under present market conditions we conclude a 100% fixed-income strategy is not going to achieve our target outcome and, since the total deposits in the RESP amount to $57,200 (including the grant portion), there is a more than 50% chance the 100% fixed-income strategy does not keep pace with inflation. We should note that thus far we have only considered gross market returns and ignored investment fees, which would further reduce returns.
100% equity option
We repeat our analysis with a well-diversified global equity portfolio. Equities have higher expected returns but also higher volatility. The median outcome rises to $91,234, but there is a 1 in 20 chance that the outcome is less than $52,331, which is less than initial contributions (including the Government grant). Whether this is an acceptable trade-off depends on the risk tolerance and circumstances of the investor. Clients who expect to have sufficient savings when the RESP funds are withdrawn to top up any shortfalls might be more tolerant of both the possibility of a poor outcome and the annual volatility along the way.
Range of scenarios
Having established the basic model we explore:
- Impact of varying the mix of bond and equities
- Impact of investing over a shorter time horizon (10 years).
In each scenario we note the median outcome (50th percentile) and the 5th percentile (i.e. the portfolio value below which 1 in 20 of the outcomes fall).

Figure 1 summarizes the results of different asset allocations for both the 20-year and 10-year investment horizons. The dashed horizontal line represents the desired outcome of covering 100% of the estimated future cost (in 2014 dollars) of post-secondary education of $68,127.
Over a 10-year period, none of the investment strategies with less than an 80% equity allocation achieve a 50% chance of success. Over 20 years a minimum 40% allocation to equities is required. In either case pursuing a higher equity allocation leads to a higher expected return.
The likelihood of a poor outcome is measured by the 5th percentiles: there is a 1 in 20 chance of outcomes below this value. Over 20 years the 5th percentile is not very sensitive to a rising equity allocation. Although equities over a one year period are more volatile than bonds, their higher expected return means that, over longer periods, the probability of a loss in value decreases while the expected value due to compound growth increases.
The net effect of these two trends is small. Over 10 years, higher equity allocations result in higher downside risk, as the compounding effect of higher equity returns is less over a shorter horizon. As a consequence, the shorter investment period has a higher probability of a bad outcome.
