The formula

Gross yield = income ÷ value; net yield = (income − expenses) ÷ value

What the bank discount yield tells you

Income relative to price — the bank discount yield number investors quote first — plus the expense-adjusted net figure that actually matters.

Calculation: Gross yield = income ÷ value; net yield = (income − expenses) ÷ value. Enter your inputs and every substitution is shown below the result.

Reading the result

A yield that beats the risk-free rate by 4+ points is doing something: it prices real risk. Read net and gross together; a fat gross with thin net is an expense problem hiding in plain sight.

Rules of thumb: Residential cap rates commonly sit 4–8 % gross; REIT dividend yields 3–6 %; the comparison that matters is the spread over treasuries.

Limitations and best practice

Trailing income is not forward income — roll the figure on contracted rents or stated coupons, not last year’s surprises.

This calculator gives an estimate based on standard formulas; it is not professional financial, medical, legal or engineering advice. Verify anything you plan to act on with a qualified professional and your own records.

Frequently asked questions

Is a higher bank discount yield always better?

No — yield is risk made visible. Distress, vacancy or one-off income inflate it; check durability before price.

Net or gross for comparisons?

Net, always. Two assets with equal gross can differ by two points of net once expenses and vacancy are honest.

Bank Discount Yield: what this tool answers

You are comparing options that arrive in different shapes, and Bank Discount Yield is the level playing field that makes them comparable. There are plenty of pages about Bank Discount Yield; almost none of them show the working. This one does: the formula, every input, a fully computed example, and a sensitivity analysis calculated live from this engine’s own defaults.

The useful way to hold Bank Discount Yield is as a ratio with a story attached: Gross yield = income ÷ value; net yield = (income − expenses) ÷ value says how the parts combine, and the 2.30% figure above is simply that sentence written in numbers. Everything that follows unpacks one clause of the sentence at a time.

Return and risk arrive as a package in Bank Discount Yield. A result of 2.30% means little until you ask what variance sits behind it, how it compares with the boring alternative (the companion tools above compute exactly that comparison), and whether the inputs assume the good scenario or the expected one.

What makes a calculation page trustworthy is that its copy is derived from its own arithmetic: here gross yield = 2.30%, recomputed every time a field changes, and the sensitivity section ranks the inputs that move the result — Asset value / price first, at ≈11.1 % of the headline for a ten-percent error either way in that input — which is the thread the rest of this guide pulls on.

Every input in Bank Discount Yield, and what it does to the answer

Here is the complete model this tool runs — Gross yield = income ÷ value; net yield = (income − expenses) ÷ value — with each input explained below. If a competitor’s page gives you a different answer from the same inputs, this is the text that settles which of you is right.

Annual income ($) (example value 16,250) is a quantity rather than a category — precision here is cheap and worth having. Keep every money input in the same currency; mixing systems quietly corrupts the comparison.

Asset value / price ($) (example value 705,000) is a measured number in the unit named by the label; the formula does not convert for you. If your source quotes a figure before and after some deduction, decide which one the formula wants and be consistent for every field.

Annual expenses / vacancy drag ($) (example value 5,970) is a numeric input whose unit is fixed by the label; a wrong unit is a wrong answer wearing a plausible disguise. If you are unsure what belongs in this field, look at the printed steps: the substitution shows exactly how the engine uses it.

Bank Discount Yield on the example inputs: the complete substitution

The tool prints its own working; this is the same arithmetic on the example values, reproduced so you can follow it by hand. Starting figures: Annual income ($), Asset value / price ($), Annual expenses / vacancy drag ($). Run to the end, the gross yield resolves to 2.30% — Barely earning — capital-gain bet dressed as income on the bands this tool uses.

Gross = $16,250.00 ÷ $705,000.00 = 2.30 %
Net = (16,250.00 − 5,970.00) ÷ 705,000.00 = 1.46 %

Net yield — 1.46%. Read next to the headline, this is the figure that shows the shape of the trade-off.

Expense ratio — 36.7%. Read next to the headline, this is the figure that shows the shape of the trade-off.

Years to recoup at net — 68.6 yrs. This is the number experienced users quote when the headline alone would mislead.

Keep this worked example open while you enter your own figures: matching the shape of the substitution is the fastest way to spot a unit or convention mistake.

How far Bank Discount Yield can reasonably move

Read this table as the practical error bar on the headline figure. It answers the question people actually have after seeing a single number: how wrong could this be if the main input is off by ten or twenty percent?

Asset value / price setting	Gross yield
80 % of the example value	2.88%
90 % of the example value	2.56%
example inputs	2.30%
110 % of the example value	2.10%
120 % of the example value	1.92%

That spread — 1.92% at the low end, 2.88% at the high — is what a careful read of Bank Discount Yield looks like: a band you can state out loud, with the reason for each edge. Reproduce it in the form above by editing Asset value / price alone; the substitution steps will follow your figures exactly.

What actually moves your Bank Discount Yield

Nobody should have to guess which input matters. The engine was re-run once per field below — ten percent up, ten percent down, everything else frozen — and the results ranked by how far they moved the gross yield. It is the fastest honest answer to “what matters most in Bank Discount Yield?” — and it is specific to these defaults, because sensitivity moves with the starting point.

Asset value / price: ten percent up gives 2.10%, ten percent down gives 2.56% — ≈11.1 % of the gross yield either way
Nudge Annual income by ±10 % and Bank Discount Yield lands between 2.07% and 2.54% (sensitivity ≈10.0 %)

Asset value / price is the dominant lever here: ten percent either way moves the result by about 11.1 %, from 2.10% to 2.56%. Measure that input from a document rather than from memory, and treat Annual income as the second priority (≈10.0 % per ten percent). The remaining fields can sit at safe defaults without materially changing the answer — knowing which is which is what separates a careful calculation from an anxious one.

Is your Bank Discount Yield good — reading the result bands

The value above only becomes useful the moment you know what it is being measured against. The verdict attached to the default calculation — “Barely earning — capital-gain bet dressed as income” — is one band on a ladder your own figure may sit somewhere else on. Before treating the band as fact, note its width: ten percent either way on Asset value / price already spans 2.10% to 2.56%. The practical reading rules: ask what would have to change to move you one band. If the answer is “a small, plausible input difference”, the band itself is not the finding — the uncertainty is.

In Investing & Markets, Bank Discount Yield is one instrument in an orchestra: on its own it is a number, next to Net yield and Expense ratio it becomes a diagnosis. The tools linked above exist so the headline never has to carry that weight alone.

How people get Bank Discount Yield wrong

Trailing income is not forward income — roll the figure on contracted rents or stated coupons, not last year’s surprises. This calculator gives an estimate based on standard formulas; it is not professional financial, medical, legal or engineering advice. Verify anything you plan to act on with a qualified professional and your own records.

Stopping at the first plausible answer. If the result surprises you, the productive question is which input would have to be wrong for the surprise to disappear — then go check that input.

One mistake is specific to this engine: assuming every input matters equally. The computation above shows Asset value / price dominating — a careful figure there beats false precision everywhere else.

Another is comparing across contexts: a Bank Discount Yield computed with one set of conventions should never be lined up against a figure computed with another. Check the inputs behind both before ranking them.

A quick check for any Bank Discount Yield figure

State, in one sentence, which convention each rate, unit or period in the form is using.
Verify each input against its original source document, not memory.
Re-verify Asset value / price against a source document — ten percent of error there moves the headline by ≈11.1 %.
Re-run the calculation with a ±10 % stress on the two most sensitive inputs.
Confirm the example values are plausible for your own situation before replacing them.
Confirm the answer against one independent method or published benchmark for Bank Discount Yield.

A routine for decision-grade Bank Discount Yield

Using a calculator well sounds trivial, but the difference between a decision-grade figure and a throwaway one lives entirely in the routine. The routine for Bank Discount Yield takes a minute to learn and applies to every input above.

Step 1 — gather before you type. Bank Discount Yield depends on annual income ($), asset value / price ($), annual expenses / vacancy drag ($). Collect them from a source document — a statement, a report, an invoice, a log — rather than from memory, because recalled inputs are the single largest cause of wrong results. Precision is a promise you make about your data; make sure your inputs can keep it.

Step 2 — baseline before exploration. Get one defensible Gross yield on screen before you start nudging numbers. Without a baseline, every variation looks interesting and none of them means anything. Rounding early is the quietest way to introduce a permanent error.

Step 3 — isolate your variables. Change one field, observe, revert. The live sensitivity list does the ranking for the default inputs; verify it against your own, because dominance shifts when the starting point shifts. Rounding early is the quietest way to introduce a permanent error.

Step 4 — compute a corridor, not a point. Three runs — worst, likely, best — turn Bank Discount Yield from a snapshot into a range. Plan against the pessimistic end and treat the optimistic end as the upside story. A figure nobody can reproduce is a figure nobody will act on twice.

Step 5 — save the story with the figure. A number without its inputs and its date is unusable within a quarter. Record 2.30%, the assumptions behind it, and today’s date; your future self will be auditing a stranger’s arithmetic. Re-running a number costs seconds; retracting a decision costs considerably more.

The real-world conversations Bank Discount Yield settles

Numbers earn their keep in conversations, and Bank Discount Yield is no exception. In Investing & Markets discussions around Fixed Income, this figure decides whether an option stays on the table: it converts an opinionated debate into an arithmetic one, and arithmetic is the only referee both sides accept. Say the answer out loud before you save it; if it sounds wrong, the model did not change, your understanding did.

The audience for this page is investors and founders comparing opportunities on equal terms. In professional Fixed Income practice the pattern is always the same — screen with Bank Discount Yield, then invest slow analysis only in whatever survives the screen. Half of a good calculation is knowing which input you would hate to be wrong about.

Nothing here is stored or transmitted, so the habit of checking is free: open the page, re-enter current figures, compare with the number you saved last time. Write the figure down before moving on; memory flatters whichever number you saw last.

What the labels on this page mean

Net yield: 1.46% on the example inputs — a companion figure printed beside the headline of Bank Discount Yield so that no result is read in isolation.
Expense ratio: 36.7% in the default Bank Discount Yield calculation — one of the secondary figures an experienced reader checks before trusting the primary number.
Years to recoup at net: 68.6 yrs on the example inputs — a companion figure printed beside the headline of Bank Discount Yield so that no result is read in isolation.
Gross yield: The primary output of this tool: 2.30% for the default inputs, computed exactly from Gross yield = income ÷ value; net yield = (income − expenses) ÷ value.
Worked example: The step-by-step substitution printed above, so the arithmetic can be re-derived by hand or in a spreadsheet.
Verdict band: The interpretation attached to a result (“Barely earning — capital-gain bet dressed as income” on these inputs), which turns a bare number into a position on a scale.
Sensitivity (±10 %): How far the Bank Discount Yield moves when a single input is nudged ten percent either way; the ranked list on this page is computed live from this engine.

Methodology, sources and limits

There is no black box on this page — the engine evaluates Gross yield = income ÷ value; net yield = (income − expenses) ÷ value. Source of record: Standard income-yield arithmetic used across REIT and property analytics. Any other implementation of this model should return the same figure for the same inputs. If one does not, the difference is in its assumptions — which this page prints and that one probably does not.

This page is an estimation aid, not professional advice. The design rule is simple: two people entering identical figures must get identical answers. The sensitivity table above is part of that promise rather than a bonus: it lets you see how much of the result depends on how carefully you measured.

Turning this Bank Discount Yield into a decision

Run the pessimistic case before the optimistic one; an opportunity that survives the pessimistic inputs is the only kind worth pursuing.

This page was written for investors and founders comparing opportunities on equal terms, and the promise is that nothing above required trust. Bookmark the tool, re-run it whenever an input moves by more than a few percent, and keep the date with the number.
