Holding Period Return Calculator
Calculate total return for any investment holding period.
What this calculator does
Holding period return measures what an investment delivered across the precise span you held it, counting income received as well as any change in value. It answers the plain question of what this holding actually did for you while you owned it.
Enter the value at the start, the value at the end including income received, and how long the period ran. The calculator returns the gain or loss in pounds, the holding period return as a percentage, and the annualised equivalent, which is what makes periods of different lengths genuinely comparable.
When to use it
HPR suits income-producing holdings owned for awkward lengths of time — a gilt held 27 months, a corporate bond fund across two and a half years, a property fund bought and sold within a year. Any price-only measure will understate these, often by a wide margin.
It is also how you build a longer return series. Because holding period returns chain by multiplication, calculating one for each stretch between contributions is the standard way to construct a clean multi-year figure for a portfolio that received money at irregular intervals.
Understanding the inputs
Beginning value is what the holding was worth when the period started, which is not necessarily your original purchase price if you are measuring a slice of a longer ownership.
Ending value should include income received during the period. If a fund distributed £2,600 and is now worth £43,500, enter £46,100. If you hold accumulation units, income is already reflected in the price, so add nothing. The holding period field takes decimals, so eighteen months is entered as 1.5 rather than 18.
How is this calculated?
HPR = (Ending Value + Income − Beginning Value) / Beginning Value × 100
A worked example
Consider a corporate bond fund holding worth £40,000 at the start of a two-year period. Over those two years it paid out £2,600 in income distributions, and at the end the holding was valued at £43,500.
Ending value plus income comes to £46,100. Less the £40,000 you began with, that is a £6,100 gain, or a holding period return of 15.25 percent. Annualised over two years, that is 7.35 percent. Capital growth supplied 8.75 percentage points and income the remaining 6.5 — a split typical of fixed income.
Limitations and assumptions
HPR is a record of what happened, not a forecast. Past returns do not predict future ones, and the annualised figure assumes a flat return with no volatility, so it reveals nothing about how far the holding fell along the way.
The measure also fails when money moves in or out mid-period, and it excludes dividend tax, capital gains tax, platform charges, and dealing costs. None of this is investment advice or a personal recommendation. For reporting that needs to stand up, use a proper time-weighted calculation instead.
Common Questions
- What exactly is holding period return?
- HPR is the total return earned over however long you actually held an asset, as a percentage of what you started with. The formula is ending value plus income received, minus beginning value, divided by beginning value. It ignores the length of the period entirely, which is both useful and a trap.
- How does HPR differ from annualised return?
- HPR is the raw total; annualised return converts it into a per-year compound rate. A 30 percent HPR earned over 18 months annualises to roughly 19 percent, while the same 30 percent over eight years is about 3.3 percent. Comparing two HPRs of different lengths without annualising is meaningless.
- Why does the income component matter so much?
- Because for many UK holdings it dominates. Gilts, corporate bond funds, and property funds deliver much of their return as coupons or distributions rather than price growth. Measuring such a holding on price alone can show a loss where the true holding period return was comfortably positive.
- Can holding period return be negative?
- Yes. If ending value plus income falls short of the beginning value, HPR is negative. Income can offset a falling price though — a bond fund that lost 4 percent in capital value while distributing 6 percent in income still produced a holding period return of roughly plus 2 percent.
- How do I chain several periods together?
- Multiply growth factors rather than adding percentages. Three years at plus 10, minus 5, and plus 8 percent give 1.10 times 0.95 times 1.08, which is 1.1286 — a cumulative 12.86 percent, not 13. The discrepancy grows with volatility, which is why sequences of returns need compounding, not addition.
- Does this work for a portfolio I pay into monthly?
- Not directly. Contributions increase the ending value without being return you earned, so the result would flatter you. Break the period at each contribution and chain the segments for a time-weighted return, or use an IRR calculation if you specifically want your contribution timing reflected in the figure.
- Is this before or after tax?
- Before tax. Outside a wrapper, the income element faces dividend tax or income tax in the year received, while capital growth is only assessed for CGT on disposal. Held within a Stocks and Shares ISA, both components are free of UK tax, so the pre-tax HPR is also what you keep.
- What should I include as income?
- Anything the holding paid out without you selling — dividends, bond coupons, fund distributions, or interest. If you hold accumulation units where income is rolled up automatically, do not add it separately: it is already inside the unit price, and counting it twice will overstate your return.
- How short a period can I measure?
- Any length at all, from a single day upward. The caution is on annualising short periods. Raising a strong one-month return to the twelfth power produces an eye-catching number with no predictive content, because one month of performance says essentially nothing about a sustainable annual rate.
