Infrastructure Return Calculator
The formula
What the infrastructure return tells you
Exactly what infrastructure return earned: total return, the annualised CAGR that makes it comparable, and the split between price gain and income.
Calculation: Total return = (sell + income − buy) ÷ buy; CAGR = ((sell + income) ÷ buy)^(1/years) − 1. Enter your inputs and every substitution is shown below the result.
Reading the result
Compare with the boring alternative over the same window — the verdict bands anchor to long-run market returns; income-heavy gains are usually steadier than price-only ones.
Rules of thumb: Long-run real equity return sits near 6–7 % nominal CAGR plus inflation; bonds run 2–4 points lower.
Limitations and best practice
Ignoring the timing of income (reinvested vs spent) can overstate a CAGR by a few tenths; dividends spent as cash belong outside the ending value.
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.

Infrastructure Return: the number, the method and the caveats
Capital decisions deserve better than a gut feeling — this page gives you the arithmetic to defend one. There are plenty of pages about Infrastructure Return; 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.
In plain terms, Infrastructure Return answers the question "Total return?". The measurement matters because it converts a situation that feels complicated — several inputs pulling in different directions — into a single number you can act on. Within Investing & Markets, Alternative Investments is the context where this figure is quoted most often, and professionals treat it as a first-pass screen rather than a verdict.
The useful way to hold Infrastructure Return is as a ratio with a story attached: Total return = (sell + income − buy) ÷ buy; CAGR = ((sell + income) ÷ buy)^(1/years) − 1 says how the parts combine, and the 0.78% figure above is simply that sentence written in numbers. Everything that follows unpacks one clause of the sentence at a time.
Nothing below is stock text pasted around a number: the worked example computes total return = 0.78% from this tool’s own defaults, and the sensitivity section ranks the inputs that move the result — Buy price / invested first, at ≈1,439.7 % of the headline for a ten-percent error either way in that input. Read the sections in order and you will be able to reproduce every figure by hand.
How Infrastructure Return is computed, line by line
Here is the complete model this tool runs — Total return = (sell + income − buy) ÷ buy; CAGR = ((sell + income) ÷ buy)^(1/years) − 1 — 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.
Buy price / invested ($) (example value 22,500) is a plain measured quantity — the unit shown in the label is the unit the formula expects. Keep every money input in the same currency; mixing systems quietly corrupts the comparison.
Sell price / value now ($) (example value 21,250) is a plain measured quantity — the unit shown in the label is the unit the formula expects. Keep every money input in the same currency; mixing systems quietly corrupts the comparison.
Holding period (years) (example value 6) is a plain measured quantity — the unit shown in the label is the unit the formula expects. Use the value as of today, not as of the last time you looked — time fields drift silently.
Income received over the hold ($) (example value 1,425) is a numeric input whose unit is fixed by the label; a wrong unit is a wrong answer wearing a plausible disguise. If your source quotes a figure before and after some deduction, decide which one the formula wants and be consistent for every field.
The default Infrastructure Return calculation, written out in full
Rather than describe the calculation, here it is end to end — every substitution in order, starting from the inputs above. Starting figures: Buy price / invested ($), Sell price / value now ($), Holding period (years), Income received over the hold ($). Run to the end, the total return resolves to 0.78% — Flat to marginal — the fees and inflation may eat it on the bands this tool uses.
- Ending value incl. income = $21,250.00 + $1,425.00 = $22,675.00
- Total return = (22,675.00 − 22,500.00) ÷ 22,500.00 = 0.78 %
- CAGR = (22,675.00 ÷ 22,500.00)^(1/6.0) − 1 = 0.13 % a year
Annualised (CAGR) — 0.13%. Compare it against the main result of 0.78% before drawing conclusions.
Net profit — $175.00. Read next to the headline, this is the figure that shows the shape of the trade-off.
Value multiple — 1.01 ×. If your inputs change, this is usually the first companion figure to move.
Income share of gain — 814.3%. Read next to the headline, this is the figure that shows the shape of the trade-off.
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.
The Infrastructure Return corridor: your result across a realistic band
Single-point answers invite false confidence, so the same engine was run across a band around the input that matters most here. Each row is a full recalculation of Infrastructure Return, not an interpolation.
| Buy price / invested setting | Total return |
|---|---|
| 80 % of the example value | 25.97% |
| 90 % of the example value | 11.98% |
| example inputs | 0.78% |
| 110 % of the example value | -8.38% |
| 120 % of the example value | -16.02% |
The corridor runs from -16.02% to 25.97% across that band — which is the range worth planning inside rather than the single 0.78% point estimate. Reproduce it in the form above by editing Buy price / invested alone; the substitution steps will follow your figures exactly.
What actually moves your Infrastructure Return
Generic advice says “it depends on your inputs”; this section says exactly how much. Each field was perturbed by ±10 % in isolation and the total return recomputed, so the ranking below is measured rather than asserted. Read it as a map of where Infrastructure Return is fragile — drawn for the example inputs, which is the map you want when deciding what to measure carefully.
- Buy price / invested +10 % → Infrastructure Return = -8.38% · −10 % → 11.98% (the total return shifts ≈1,439.7 %)
- Nudge Sell price / value now by ±10 % and Infrastructure Return lands between -8.67% and 10.22% (sensitivity ≈1,214.3 %)
- Income received over the hold: ten percent up gives 1.41%, ten percent down gives 0.14% — ≈81.4 % of the total return either way
Buy price / invested is the dominant lever here: ten percent either way moves the result by about 1,439.7 %, from -8.38% to 11.98%. Measure that input from a document rather than from memory, and treat Sell price / value now as the second priority (≈1,214.3 % 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 Infrastructure Return 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 — “Flat to marginal — the fees and inflation may eat it” — is one band on a ladder your own figure may sit somewhere else on. The sensitivity list shows how far a modest input error moves you along that ladder: for Buy price / invested, ±10 % covers -8.38% to 11.98%. 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.
Placing this figure in context: calculators of this kind differ less in arithmetic than in what they choose to ignore. This one keeps Buy price / invested ($) explicit so that the omissions are visible rather than hidden in a preset.
How people get Infrastructure Return wrong
Ignoring the timing of income (reinvested vs spent) can overstate a CAGR by a few tenths; dividends spent as cash belong outside the ending value. 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.
Chasing one metric. Infrastructure Return needs its pair (Annualised (CAGR)) the way a speedometer needs fuel pressure — one number alone has burned more portfolios than bad markets.
One mistake is specific to this engine: assuming every input matters equally. The computation above shows Buy price / invested dominating — a careful figure there beats false precision everywhere else.
The subtlest error is answering the wrong question precisely. Confirm that total return is actually the quantity your decision needs — the arithmetic is flawless either way, which is what makes the mistake invisible.
Six things to confirm before acting on Infrastructure Return
- Compare the output against one published benchmark or a colleague’s independent estimate.
- Record the date and the inputs alongside the number so future-you knows what was assumed.
- Put Buy price / invested under a magnifier; the sensitivity table above is the reason why.
- Recompute once with the dominant input deliberately set low, and see whether the decision changes.
- State, in one sentence, which convention each rate, unit or period in the form is using.
- Repeat the ±10 % test on the inputs that matter and see whether the decision — not just the number — still holds.
A routine for decision-grade Infrastructure Return
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 Infrastructure Return takes a minute to learn and applies to every input above.
Step 1 — gather before you type. Infrastructure Return depends on buy price / invested ($), sell price / value now ($), holding period (years), income received over the hold ($). 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. Repeating a calculation with the same numbers proves only that the arithmetic is reliable — which is worth knowing.
Step 2 — enter the conservative case first. Resist the flattering scenario. Type the inputs you would defend in front of a sceptical reader, read the Total return (0.78% for the example values), and note the verdict band. Precision is a promise you make about your data; make sure your inputs can keep it.
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. Estimates improve most when the worst case is written down in ink.
Step 4 — run the scenario trio. Expected, pessimistic, optimistic. The gap between pessimistic and expected is the number to plan against; the optimistic result is useful only as a ceiling. Note the assumption you are least sure about; that is where the real risk lives.
Step 5 — save the story with the figure. A number without its inputs and its date is unusable within a quarter. Record 0.78%, the assumptions behind it, and today’s date; your future self will be auditing a stranger’s arithmetic. Write the assumptions in the same file as the result, and future arguments take minutes instead of meetings.
The real-world conversations Infrastructure Return settles
Investing & Markets arguments end at arithmetic or they do not end. Infrastructure Return is the arithmetic: 0.78% on the example inputs, reproducible by anyone who types the same numbers. 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 Alternative Investments practice the pattern is always the same — screen with Infrastructure Return, then invest slow analysis only in whatever survives the screen. If the answer changes your behaviour, it deserves a second run with different assumptions.
There is a personal-administration use people overlook: periodic self-checking. Infrastructure Return quietly drifts as life changes — rates move, bodies change, costs compound — and re-running it a few times a year catches drift while correction is still cheap. Comparisons are cheap: run the identical calculation for the alternative and look at the gap.
Infrastructure Return — frequently asked questions
What affects Infrastructure Return the most?
Measured on this engine, Buy price / invested is the dominant lever: moving it ±10 % shifts the total return across -8.38% to 11.98% — about 1,439.7 % of the headline, with Sell price / value now next at ≈1,214.3 %. The ranked list in the sensitivity section is computed live, not asserted from a template.
Which matters more: sell price / value now or buy price / invested?
For Infrastructure Return, Buy price / invested wins the head-to-head (≈1,439.7 % against ≈1,214.3 % per ten-percent change). Knowing which input dominates is the difference between careful work and merely slow work.
What is a typical Infrastructure Return?
With the example inputs on this page the result is 0.78%, labelled “Flat to marginal — the fees and inflation may eat it”. “Typical” varies with situation, which is why every result here ships with its verdict band and its sensitivity list: they turn one figure into a range you can locate yourself inside.
How do I calculate Infrastructure Return by hand?
Use the stated model — Total return = (sell + income − buy) ÷ buy; CAGR = ((sell + income) ÷ buy)^(1/years) − 1 — and substitute in the order the tool prints (it starts from Ending value incl. income = $21,250.00 + $1,425.00 = $22,675.00). On the example inputs the hand route lands on 0.78%, exactly what the calculator shows. A spreadsheet reproduces it in two or three cells; doing it once by hand is what makes the automated answer trustworthy.
What happens to Infrastructure Return if buy price / invested changes by 10 %?
On these inputs a ±10 % change in buy price / invested takes Infrastructure Return to -8.38% against the 0.78% example — around 1,439.7 % of the headline. The same test on every other field is in the sensitivity section.
Is the Infrastructure Return result of 0.78% good or bad?
Good and bad are comparisons, so the honest test is three questions: where does your own Infrastructure Return sit against the 0.78% reference above, how far would a plausible input error move it (≈1,439.7 % per ten percent on Buy price / invested), and what does the alternative option compute to?
Is Infrastructure Return accurate?
The arithmetic is exact: Total return = (sell + income − buy) ÷ buy; CAGR = ((sell + income) ÷ buy)^(1/years) − 1 is evaluated with full floating-point precision and every substitution is printed in the worked example. What limits accuracy is input quality and the model’s assumptions, so treat the 0.78% result as the correct answer to the question you typed — and check the assumptions section before acting on it.
How do I calculate Infrastructure Return manually?
Write down the inputs, then follow the printed steps in order — Total return = (sell + income − buy) ÷ buy; CAGR = ((sell + income) ÷ buy)^(1/years) − 1. A spreadsheet replicates it with two or three cells. The manual route is worth doing once to build intuition; after that the calculator saves time and eliminates transcription slips.
Why does CAGR differ from average yearly return?
CAGR compounds — it is the single steady rate that turns the start into the end, while arithmetic averages flatter volatile paths.
Are taxes included?
No, this is the pre-tax picture; subtract tax drag on gains and income before comparing with a tax-sheltered alternative.
Is my data private on this page?
Yes — computation happens locally in your browser, with no account, no tracking of your inputs and nothing sent to a server. The printed formula is the whole story of what happens to your figures.

Methodology, sources and limits
There is no black box on this page — the engine evaluates Total return = (sell + income − buy) ÷ buy; CAGR = ((sell + income) ÷ buy)^(1/years) − 1. Source of record: Time-weighted return arithmetic per CFA Institute conventions. 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.
Nothing here replaces a qualified professional, and nothing here is approximate either — the arithmetic is exact, and the honesty is in the inputs you supply. 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.
After the number: what to do with it
Run the pessimistic case before the optimistic one; an opportunity that survives the pessimistic inputs is the only kind worth pursuing.
The audience here is investors and founders comparing opportunities on equal terms. Everything you need to defend the result — formula, substitution, sensitivity, source — is printed above, so the only remaining variable is the honesty of your inputs.
