Coin Return Calculator
The formula
What the coin return tells you
Exactly what coin 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.

Coin Return explained: formula, worked example and honest limits
You are comparing options that arrive in different shapes, and Coin Return is the level playing field that makes them comparable. Searchers land on a Coin Return page for three reasons — to plan, to compare options, and to check that somebody else’s arithmetic is honest. This tool serves all three, and everything after the calculator explains the model instead of hiding it.
Return and risk arrive as a package in Coin Return. A result of 56.30% 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.
There is a habit that separates people who get useful answers from Alternative Investments numbers: they decide what question the figure answers before they compute it. Coin Return answers “Total return?” — and nothing else, which is precisely why the result is trustworthy.
Every figure in the prose is generated by the engine rather than written beside it — the worked example resolves to total return = 56.30% on the default inputs, and the sensitivity section ranks the inputs that move the result — Buy price / invested first, at ≈30.8 % of the headline for a ten-percent error either way in that input. Work down the page and by the end you could re-derive the result in a spreadsheet from memory.
Every input in Coin Return, and what it does to the answer
One formula, published in full: Total return = (sell + income − buy) ÷ buy; CAGR = ((sell + income) ÷ buy)^(1/years) − 1. Anything you can read, you can reproduce in a spreadsheet, and that reproducibility is the whole point of printing it rather than hiding it behind a button.
Buy price / invested ($) (example value 20,250) is a measured number in the unit named by the label; the formula does not convert for you. Keep every money input in the same currency; mixing systems quietly corrupts the comparison.
Sell price / value now ($) (example value 30,250) is a measured number in the unit named by the label; the formula does not convert for you. Keep every money input in the same currency; mixing systems quietly corrupts the comparison.
Holding period (years) (example value 6) is a numeric input whose unit is fixed by the label; a wrong unit is a wrong answer wearing a plausible disguise. Be precise about the boundary (exact date, start of month); time inputs decide the exponent in most formulas.
Income received over the hold ($) (example value 1,400) is a measured number in the unit named by the label; the formula does not convert for you. If your source quotes a figure before and after some deduction, decide which one the formula wants and be consistent for every field.
Coin Return with real numbers, step by step
Abstract formulas are hard to trust, so here is the complete substitution using the default inputs, written the way an examiner would want it. Starting figures: Buy price / invested ($), Sell price / value now ($), Holding period (years), Income received over the hold ($). The endpoint of that chain is 56.30% of total return, sitting in the “Solid gain, roughly at or above long-run equity returns” band.
- Ending value incl. income = $30,250.00 + $1,400.00 = $31,650.00
- Total return = (31,650.00 − 20,250.00) ÷ 20,250.00 = 56.30 %
- CAGR = (31,650.00 ÷ 20,250.00)^(1/6.0) − 1 = 7.73 % a year
Annualised (CAGR) — 7.73%. This is the number experienced users quote when the headline alone would mislead.
Net profit — $11,400.00. This is the number experienced users quote when the headline alone would mislead.
Value multiple — 1.56 ×. If your inputs change, this is usually the first companion figure to move.
Income share of gain — 12.3%. Compare it against the main result of 56.30% before drawing conclusions.
Re-running with your own figures is instant; re-running by hand once is the best way to know the tool is telling you the truth.
How far Coin Return 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?
| Buy price / invested setting | Total return |
|---|---|
| 80 % of the example value | 95.37% |
| 90 % of the example value | 73.66% |
| example inputs | 56.30% |
| 110 % of the example value | 42.09% |
| 120 % of the example value | 30.25% |
The corridor runs from 30.25% to 95.37% across that band — which is the range worth planning inside rather than the single 56.30% point estimate. Reproduce it in the form above by editing Buy price / invested alone; the substitution steps will follow your figures exactly.
Where Coin Return is fragile — and where it is not
This list was computed for this specific engine just now: each numeric input was nudged ±10 % while every other field held its example value, and the total return was recalculated from scratch. For Coin Return the ranking is measured rather than guessed, and it belongs to these defaults: shift the starting point and the order can shift with it.
- Nudge Buy price / invested by ±10 % and Coin Return lands between 42.09% and 73.66% (sensitivity ≈30.8 %)
- Nudge Sell price / value now by ±10 % and Coin Return lands between 41.36% and 71.23% (sensitivity ≈26.5 %)
- Nudge Income received over the hold by ±10 % and Coin Return lands between 55.60% and 56.99% (sensitivity ≈1.2 %)
Buy price / invested is the dominant lever here: ten percent either way moves the result by about 30.8 %, from 42.09% to 73.66%. Measure that input from a document rather than from memory, and treat Sell price / value now as the second priority (≈26.5 % per ten percent). Everything below that can stay approximate, which is a licence to stop chasing data that would not change the decision.
What a Coin Return of 56.30% means in practice
Nobody acts on a bare figure — they act on a figure with a comparison attached. On the example inputs the band reads “Solid gain, roughly at or above long-run equity returns”; your own figures place you on a different rung of the same ladder. The sensitivity list shows how far a modest input error moves you along that ladder: for Buy price / invested, ±10 % covers 42.09% to 73.66%. 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.
Why Coin Return results go wrong — and how to prevent it
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. Coin Return needs its pair (Annualised (CAGR)) the way a speedometer needs fuel pressure — one number alone has burned more portfolios than bad markets.
Attention is also misallocated between fields. Having measured this engine, we can say where it belongs: Buy price / invested first, everything else second.
Another is comparing across contexts: a Coin Return 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.
Coin Return verification checklist
- Note the date and the inputs beside the number so the figure can be audited later.
- Confirm the example values are plausible for your own situation before replacing them.
- Check Buy price / invested before anything else: it is the measured dominant input, ≈30.8 % of Coin Return per ten percent.
- State, in one sentence, which convention each rate, unit or period in the form is using.
- Re-run the calculation with a ±10 % stress on the two most sensitive inputs.
- Run the ±10 % stress on the top two levers and check that your conclusion survives both.
A routine for decision-grade Coin Return
The tool does the arithmetic; the routine below is what makes the arithmetic trustworthy. Five steps, a minute total — and afterwards you will know not just what the number is, but which assumption produced it.
Step 1 — start from evidence. The inputs behind Coin Return are buy price / invested ($), sell price / value now ($), holding period (years), income received over the hold ($). Write them down with their source next to each one; if you cannot name where a figure came from, that is the input most likely to be wrong. A figure with a date beside it becomes evidence; without one it stays an anecdote.
Step 2 — compute the version you would not be embarrassed by. If a stranger audited your inputs, which set would you hand over? Enter that set, read the result, and treat everything else as upside. Rounding early is the quietest way to introduce a permanent error.
Step 3 — change one input at a time. Nudge a single field by ten percent, watch the headline and its companions move, then undo it. Two or three fields will dominate — the sensitivity table above already ranks them for this engine. Say the answer out loud before you save it; if it sounds wrong, the model did not change, your understanding did.
Step 4 — stress before you commit. A decision that survives a ten-percent squeeze on its two biggest inputs needs no luck to be sound. One that does not survive is a decision about hope, not about arithmetic. A calculation you cannot explain to somebody else is a calculation you cannot defend.
Step 5 — save the story with the figure. A number without its inputs and its date is unusable within a quarter. Record 56.30%, the assumptions behind it, and today’s date; your future self will be auditing a stranger’s arithmetic. Suspiciously tidy answers deserve the same scrutiny as untidy ones.
From calculation to decision: where Coin Return earns its keep
Numbers earn their keep in conversations, and Coin Return is no exception. In Investing & Markets discussions around Alternative Investments, 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. Most surprises in numbers are surprises about inputs, not about formulas.
Professionals in Alternative Investments use this style of calculation as a screening filter before spending real money or effort: a quick Coin Return check eliminates weak options in minutes, and the survivors earn the deeper, slower analysis. The test of a good estimate is not that it feels right but that it changes what you do.
Treat Coin Return like a smoke alarm rather than a painting — its value is in being tested periodically, not in being admired once. Note the assumption you are least sure about; that is where the real risk lives.
Quick answers: what searchers ask about Coin Return
What affects Coin Return the most?
Measured on this engine, Buy price / invested is the dominant lever: moving it ±10 % shifts the total return across 42.09% to 73.66% — about 30.8 % of the headline, with Sell price / value now next at ≈26.5 %. 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?
By the numbers, Buy price / invested: a ten-percent change in it moves the result ≈30.8 %, versus ≈26.5 % for Sell price / value now. Spend your measuring effort in that order — precision on the weaker lever buys almost nothing.
What is a typical Coin Return?
On the worked example above Coin Return comes out at 56.30%. Treat that as one point on a distribution rather than a norm: the bands, the companion outputs and the sensitivity ranking tell you how wide the plausible range really is.
How do I calculate Coin Return by hand?
Three steps: write the formula (Total return = (sell + income − buy) ÷ buy; CAGR = ((sell + income) ÷ buy)^(1/years) − 1), insert your values, and simplify. The worked example section shows exactly that chain for the default inputs; replicating it once on paper teaches you more about Coin Return than any number of calculator runs.
What happens to Coin Return if buy price / invested changes by 10 %?
Try it in the form above and the printed substitution will follow you; the pre-computed answer for the defaults is 42.09% to 73.66% across the ten-percent probe, i.e. ≈30.8 % sensitivity on the total return.
Is the Coin Return result of 56.30% good or bad?
The tool answers “what”, not “whether”: 56.30% carries the verdict “Solid gain, roughly at or above long-run equity returns” for the default case, which is a starting interpretation rather than a verdict on your situation. Re-run with your own figures and compare the bands.
What is a good Coin Return?
Markets give away free benchmarks: anything that beats the relevant index after costs earns the label "good", and this tool’s verdict band translates Coin Return against experience ranges. Before that, check that the inputs are realistic — a great Coin Return built on optimistic inputs is just a nicer-looking error.
Can I predict future returns with Coin Return?
No tool predicts; Coin Return computes implications. Use it to ask "if these inputs hold, what follows" — then stress the assumptions.
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.
Do I need an account to use this Coin Return calculator?
No, and no data leaves the tab. The engine runs in the page itself, which is why the worked example, the bands and the sensitivity ranking all respond instantly to your keystrokes.
What the labels on this page mean
- Annualised (CAGR)
- 7.73% on the example inputs — a companion figure printed beside the headline of Coin Return so that no result is read in isolation.
- Net profit
- $11,400.00 for the Coin Return worked case; it sits next to the main result because it carries context the headline leaves out.
- Value multiple
- 1.56 × on the example inputs — a companion figure printed beside the headline of Coin Return so that no result is read in isolation.
- Total return
- The primary output of this tool: 56.30% for the default inputs, computed exactly from Total return = (sell + income − buy) ÷ buy; CAGR = ((sell + income) ÷ buy)^(1/years) − 1.
- Worked example
- The calculation written out in full so that nothing on this page has to be taken on trust.
- Verdict band
- A named zone on the range of plausible results; the example inputs land in “Solid gain, roughly at or above long-run equity returns”, and your inputs may not.
- Sensitivity (±10 %)
- How far the Coin Return moves when a single input is nudged ten percent either way; the ranked list on this page is computed live from this engine.
Where the Coin Return model comes from
The model is published arithmetic implemented exactly as written: 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. What that buys you is reproducibility — two people, two browsers, the same arithmetic, and a printed trail from inputs to result that either of them can audit.
What to do with your Coin Return next
Pair this figure with the companion outputs above — the headline sizes the prize, the companions describe the risk.
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.
