How to Calculate Your Fixed-Income and Cash Allocation

Updated September 26, 2026.

To calculate your fixed-income and cash allocation, add the market values of those holdings across the accounts you want to include, then divide each total by the value of that same portfolio. Use one valuation date, classify mixed funds carefully, and decide whether emergency savings belong in the denominator before interpreting the result.

The most useful answer has three parts: the percentage, what is included, and what the money is for. A household with a large tax payment next month may correctly hold more cash than a retirement-only allocation would suggest.

Mezzi can bring connected investments, checking and savings, credit-card liabilities, and manually entered assets such as real estate into a broader financial picture. That helps you ask a better allocation question. You still need to check account coverage, holding classifications, and which assets the answer includes.

Start with the portfolio you actually mean

“Across my portfolio” can describe several different calculations. Pick one and label it.

A home belongs in the household picture, but adding its estimated value to an investment-allocation denominator can make stock and bond percentages look smaller without reducing their dollar exposure. Similarly, subtracting a mortgage from an investment portfolio can distort its asset weights. Keep the net-worth statement and the investment-allocation calculation separate, then use both when planning.

Joint accounts are another common source of error. If two people connect the same account, count its holdings once in a combined household calculation. If you are allocating only one person's economic share, document that convention instead.

Classify the holdings before adding them

The account name does not tell you the asset class. A brokerage account may hold stocks, bonds, and a cash sweep. An IRA may hold a money market fund. A savings account is different from a bond fund even when their recent yields look similar.

Use one consistent policy for short-term instruments. A Treasury bill can be grouped with cash equivalents for a liquidity-oriented report and with fixed income in another analysis. Either approach needs a clear label; counting it in both is wrong.

Money market funds are investment funds, not FDIC-insured bank deposits. Bond funds can lose value as interest rates or credit conditions change. These distinctions matter when you are deciding which assets could cover a bill. Investor.gov: money market funds and bond-fund risks.

A worked allocation across three accounts

Suppose a household has the following holdings on the same date. These are hypothetical values, not a recommended allocation.

Fixed-income allocation is $130,000 ÷ $500,000 = 26%. Cash allocation is $70,000 ÷ $500,000 = 14%. Combined, they represent 40% of these financial assets.

If the question concerns only the investment accounts, exclude the $50,000 of bank balances from both the cash total and the denominator. Fixed income becomes $130,000 ÷ $450,000 = 28.89%, and cash becomes $20,000 ÷ $450,000 = 4.44%. Both answers can be correct because they describe different scopes.

Do not average the percentages reported by the three institutions. An account worth $280,000 should have more influence than an account worth $50,000. Add dollars first, then calculate percentages.

Now suppose $30,000 of the bank cash is an emergency reserve and $20,000 is reserved for taxes. That is still $50,000 of cash on the balance sheet. It is not automatically $50,000 available to invest. A useful report shows both the asset class and the assignment of that money.

Handle mixed funds and missing data explicitly

Imagine a $40,000 balanced fund reports a 60% stock and 40% bond allocation for the relevant date. For a simple look-through estimate, assign $24,000 to stocks and $16,000 to bonds. Do not also retain the entire $40,000 as a separate asset-class amount, which would double count it.

If current holdings are unavailable, report the fund as mixed or unclassified. A clearly marked unknown is more informative than treating the entire balance as stocks because of a default category.

For example, “26% confirmed fixed income, with 8% of the portfolio in a mixed fund awaiting classification” is a more honest answer than a seemingly precise percentage based on a guess. It also tells you exactly what information to collect next.

Fund data and account balances may refresh on different schedules. Save the analysis date, the underlying holdings dates where available, and any manual adjustments. For a portfolio X-ray, check the exact fund coverage rather than assuming every bond or underlying position is captured. Learn how portfolio look-through works.

Use the percentage to make a decision

An allocation number is descriptive. Whether it fits depends on the jobs the money must do.

For cash, list upcoming bills, emergency needs, and planned large expenses. Then distinguish funds that are accessible immediately from assets requiring a sale, settlement, transfer, or maturity. A large total is not a substitute for money available on the needed date.

For fixed income, look beyond the category total. A long-duration government-bond fund, a short-term Treasury holding, and a high-yield corporate-bond fund can behave differently. Review interest-rate sensitivity, credit exposure, currency, and the relationship between maturities and planned spending.

For your longer-term investment policy, compare the calculated weights with a target chosen for your time horizon and risk capacity. There is no universal cash or bond percentage that fits every household. The SEC's allocation guidance emphasizes the relationship between asset allocation, time horizon, and risk tolerance.

If a change is warranted, consider new contributions and withdrawals before selling existing holdings. Sales may have tax consequences, and an apparently cleaner allocation is not necessarily worth the cost of reaching it immediately.

A practical Mezzi workflow

Begin with your account inventory: investments, Banking accounts, Other assets, and Liabilities. Reconcile important balances against the source institution and flag anything missing or stale. Real estate can add context to the household plan even when it is excluded from the investment calculation.

Use AI Personalization to explain rules that would otherwise be invisible in a balance report. For example:

Keep my $30,000 emergency reserve separate from my investment allocation. Another $20,000 is earmarked for taxes. Evaluate the remaining investment accounts together, and ask me before treating any unclassified fund as stocks or bonds.

Then ask a question with a defined scope:

Using my selected investment accounts, help me calculate fixed-income and cash allocations. Show the dollar totals, denominator, account dates, classification assumptions, and anything you cannot verify.

Review the answer against the account and fund records. This is a workflow for a better financial conversation, not a promise that every asset has automatic look-through coverage or that Mezzi will execute a rebalance. Check current membership features for the advice and support available to you.

Frequently asked questions

Should emergency savings count as cash in my portfolio?

They count as cash in a household financial-assets view. You may exclude them from an investment-only allocation if you also exclude them from that calculation's denominator. Label the scope and keep the reserve's purpose visible.

Are money market funds the same as insured savings accounts?

No. Money market funds are investments and are not FDIC-insured deposits. Eligible bank deposits have insurance limits and ownership-category rules. Check the actual product rather than relying on its name. FDIC coverage overview.

Why do two tools show different cash allocations?

They may include different accounts, use different balance dates, classify short-term instruments differently, or handle mixed funds differently. Reconcile the dollar amounts and scope before deciding that one percentage is wrong.

Does a higher bond allocation guarantee less risk?

No. Bond risks differ by duration, issuer, currency, and structure. A category percentage alone does not establish how the holdings could behave or whether they can meet a spending need.
