Retirement Cash Reserve
Someone who is about a year from retirement often starts looking at cash differently. While a salary is still arriving, a market decline may be uncomfortable, but regular income continues to replenish the bank account. Once employment income stops, the portfolio may need to take on that role. Holding a cash reserve before retirement can therefore be sensible, but the right amount is not determined by a standard percentage of the portfolio.
The more useful question is: what specific cash-flow job does the reserve need to do? The answer depends on the spending that must come from investments, the income already available, the length of the desired runway and any known expenses ahead. It also depends on where the reserve is held and how it will be replenished over time.
Start With the Spending Gap
A retirement cash reserve can reduce the pressure to sell long-term investments during a market decline. It does not remove market risk or eliminate sequence-of-returns risk. Its purpose is narrower: it provides a source of liquidity for near-term spending while the household decides when and how to draw from the rest of the portfolio.
That is why a rule such as holding 10% or 15% of the portfolio in cash can be incomplete. Two households may each have $2 million invested and the same annual spending target, but need very different reserves. A couple with dependable pension income covering most regular expenses places a much smaller burden on the portfolio than a household that expects investments to fund nearly all spending.
The calculation should begin with the household’s annual spending gap: after-tax spending minus dependable after-tax income available during the period being covered. Both figures need to be measured consistently. Comparing an after-tax spending target with a gross pension amount can make the required reserve appear smaller than it really is.
Only income that is dependable and available during the reserve period should be included. A pension beginning immediately may reduce the gap. CPP, OAS or another income source that will not begin for several years cannot fund spending before it starts. If an income source begins partway through the period, calculate the gap in stages rather than assuming a full year of income from the outset.
Build the Reserve Requirement
Consider a hypothetical couple, Michael and Sandra, who expect to retire in about a year. They have $2 million of investable assets, including $20,000 of eligible cash that is stable, liquid and not committed to another purpose. They expect to spend $120,000 annually after tax and will receive $54,000 of dependable, spendable pension income during the period being considered. CPP and OAS are not yet starting.
Their portfolio-funded spending gap is therefore $66,000 per year: $120,000 of spending less $54,000 of pension income. That figure, rather than their total annual spending or a percentage of their portfolio, is the starting point for the reserve.
A complete reserve calculation has three components:
- The portfolio-funded spending gap for the chosen period.
- An operating-account floor for regular bills and timing differences.
- Known one-time expenses that fall within the reserve period.
Michael and Sandra want to maintain a $15,000 operating-account floor. This is not an additional year of spending. It is a minimum balance intended to keep day-to-day banking from becoming fragile when several bills arrive at once. They also expect to complete a $30,000 home project during their first year of retirement, so that cost belongs in any reserve horizon of 12, 18 or 24 months.
For an 18-month reserve, the portfolio must fund one and a half years of their $66,000 gap, or $99,000. Adding the $15,000 operating floor and the $30,000 home project produces a total reserve requirement of $144,000.
The $20,000 they already hold does not change the total job the reserve must perform. It reduces only the amount that still needs to be raised from other investments. In this case, Michael and Sandra need an additional $124,000 of cash or near-cash holdings. Keeping the total requirement separate from the additional amount avoids a common error: subtracting existing cash twice and underfunding the reserve.
Choose the Right Runway
The formula does not determine how many months of spending a household should hold. That is a planning judgment. A 12-month reserve may be appropriate for a couple with dependable pension income, flexible discretionary spending, a liquid portfolio and comfort using other defensive assets when markets are weak. A longer horizon may be warranted when spending is difficult to reduce, future income is uncertain, assets are less liquid or one spouse needs more visible runway to remain comfortable with the investment plan.
For Michael and Sandra, the numbers illustrate the trade-off:
- 12 months: $66,000 of portfolio-funded spending, plus the $15,000 operating floor and $30,000 project, creates a total requirement of $111,000. After existing cash, they need to raise $91,000, or about 4.6% of their portfolio.
- 18 months: Their total requirement is $144,000. After existing cash, they need to raise $124,000, or about 6.2% of their portfolio.
- 24 months: $132,000 of portfolio-funded spending, plus the operating floor and home project, creates a total requirement of $177,000. After existing cash, they need to raise $157,000, or about 7.9% of their portfolio.
The 18-month option is a reasonable discussion point in this scenario, not a universal recommendation. Compared with a 12-month reserve, it requires holding an additional $33,000 in cash-like investments. The household needs to decide whether that additional runway is worth the trade-off.
A fixed 15% cash rule would produce a $300,000 target for Michael and Sandra. With $20,000 already available, they would need to raise another $280,000. Their 18-month cash-flow calculation calls for $144,000 in total, or $124,000 of additional cash. That does not mean 15% is excessive in every situation. Another household may have less dependable income, larger known expenses, limited spending flexibility or less-liquid investments. The difference is that the reserve should be connected to an identifiable need.
Holding more cash can offer comfort and a longer liquidity runway, but it also leaves more capital outside long-term investments. If the additional $156,000 required under a 15% rule remained unused for a year, and long-term investments earned five percentage points more than cash over that period, the potential foregone growth would be about $7,800. That outcome is not guaranteed, and cash may be more valuable during a market decline. It does show why more cash is not automatically better.
Match Liquidity to Timing
Once the amount is established, the entire reserve does not need to sit in a chequing account. Each component should be held according to when it is likely to be used. The operating-account floor needs immediate access. The home project money should be available when the contractor needs to be paid. Later spending can often be held in stable, reasonably liquid near-cash holdings that align with the expected withdrawal calendar.
The relevant question is not whether a product is described as cash. It is whether it can be accessed when needed, whether its value can change, and whether restrictions or penalties apply if funds are required sooner than expected. A maturity date is useful only when it aligns with the household’s expected cash needs.
Deposit protection also requires attention. CDIC insures eligible deposits, including principal and interest, up to $100,000 in each insured category at each member institution. Not every cash-like investment is an eligible deposit. Coverage depends on the product, institution and ownership category, so a concentrated reserve should be reviewed rather than assumed to be fully protected.
Consider Account Location and Tax
Cash can be held inside an RRSP, TFSA or non-registered account. Those choices affect both access and tax. Selling an investment and holding the proceeds as cash inside an RRSP does not itself create a withdrawal. Moving that cash out of the RRSP generally creates taxable income. A TFSA withdrawal is generally tax-free, although the withdrawn amount is added back to contribution room only in the following calendar year.
In a non-registered account, transferring existing cash to a bank account is not itself a tax event. However, selling investments to create that cash can realize a capital gain or loss. Interest earned on cash and near-cash investments in a non-registered account is fully taxable at the investor’s marginal rate. Two holdings with the same stated return may therefore produce different after-tax results.
There is an additional practical issue when a reserve is intended to provide after-tax spending. Michael and Sandra’s $66,000 gap is an after-tax amount. If part of that spending will be funded from an RRSP or RRIF, a larger pre-tax withdrawal may be required to leave the same amount available after tax. The account source and expected tax consequences need to be incorporated before the reserve is implemented.
It is also worth checking whether existing bonds or other defensive assets are already serving part of the liquidity function. Creating a separate cash reserve without considering those holdings can duplicate the same role and leave more of the portfolio defensive than intended.
Use and Review the Reserve
A cash reserve is meant to be used. As withdrawals occur, the household can review upcoming spending, maturing holdings, available income, portfolio positioning and the tax consequences of the next withdrawal. Replenishment should not be automatic. Selling growth investments immediately after a market decline just to restore the original cash balance can recreate the forced-selling pressure the reserve was intended to reduce.
Depending on the circumstances, replenishment may come from unspent pension income, a maturing near-cash holding, a planned portfolio sale or rebalancing after an asset class has performed well. In some periods, modest changes to discretionary spending may be more sensible than restoring the reserve at an unattractive time.
The reserve should also be revisited when spending changes, a known project is completed, a new income source begins or the household’s comfort level changes. Its role is to support the retirement plan, not become a permanent and unexplained cash allocation.
A Household-Specific Decision
The right retirement cash reserve begins with the spending the portfolio must actually fund, then adds a chosen runway, an operating balance and known expenses. It should have a defined purpose, expected use date and appropriate account location. That approach gives a household liquidity when the paycheque stops without moving more of the portfolio into cash-like investments than the plan requires.
If you are approaching retirement and have several income sources, account types or planned expenses to coordinate, Ferguson Financial Planning can help model the cash-flow, tax and portfolio implications using your specific numbers. The objective is not to apply a standard cash percentage, but to determine what level of liquidity fits the retirement plan you are building.
