The four returns a rental produces
Ask a landlord what their rental returns and most will quote cash flow. That is one of four sources of return, and on a leveraged property in its early years it is frequently the smallest.
- Cash flow. Rent minus operating costs minus the mortgage. Real money, arriving monthly, and the only component you can spend.
- Principal paydown. Every mortgage payment retires some balance. It is not cash in hand, but your net worth rises by exactly that amount, and the tenant is paying it.
- Appreciation. The change in market value. Unrealised until you sell or refinance, and the component with by far the widest error bars.
- Tax treatment. Depreciation shelters part of the rental income from tax. This calculator is pre-tax, so that fourth component sits outside it — see the rental property depreciation calculator.
The first-year return here adds the first three and divides by the cash you invested. On the default figures — $2,490 of cash flow, $2,011 of principal paydown, $9,000 of appreciation, on $84,000 invested — cash flow is 2.96 percentage points of a 16.07% total. Judging that property by cash flow alone would understate its first year by more than a factor of five.
Why leverage amplifies all three components
The reason a rental can produce a double-digit return on a 3% appreciation assumption is arithmetic, not optimism. You invested $84,000 but you control $300,000 of property, so a 3% move in value is $9,000 — which is 10.7% of your capital. Leverage multiplies the value change by the ratio of asset to equity, and it does so in both directions.
The principal paydown component grows every year. On an amortising loan the split between interest and principal shifts steadily toward principal, so the same payment retires more balance each year. In the default example, the loan retires $2,011 in year one and roughly $2,145 in year two — the growth rate is the loan's own interest rate, because each dollar of principal retired stops accruing interest at exactly that rate.
The appreciation component grows too, since a constant percentage applied to a growing value produces a growing dollar amount. That is why the year-one return and the annualised return over a long hold are different numbers, and why the projection table matters more than the headline.
The annualised figure is a compound rate, not an average. It takes everything you receive — cumulative cash flow plus net proceeds at sale — divides by what you put in, and asks what constant annual rate would have produced that multiple over the hold. That makes it directly comparable to a stock market return or a bond yield, which the first-year figure is not.
Worked example: $300,000 property, $84,000 invested, five-year hold
You own a $300,000 rental with $180,000 outstanding at 6.5% over 30 remaining years. You invested $84,000 in total. It generates $2,490.54 of cash flow, and you assume 3% appreciation, flat cash flow, and 6% selling costs on exit in five years.
- Monthly payment. r = 0.065 ÷ 12 = 0.00541667, n = 360. M = 180,000 × 0.00541667 ÷ (1 − 1.00541667−360) = $1,137.72.
- Balance after 12 payments. B = 180,000 × 1.0054166712 − 1,137.72 × (1.0054166712 − 1) ÷ 0.00541667 = 192,054.92 − 14,065.77 = $177,989.15. So principal paydown in year one is $2,010.85.
- Appreciation in year one. 300,000 × 0.03 = $9,000.
- First-year total gain. 2,490.54 + 2,010.85 + 9,000 = $13,501.39.
- First-year total return. 13,501.39 ÷ 84,000 = 16.07%, made up of 2.96% cash flow, 2.39% paydown and 10.71% appreciation.
- Return on current equity. Equity today is 300,000 − 180,000 = $120,000, so 13,501.39 ÷ 120,000 = 11.25%.
- Value in five years. 300,000 × 1.035 = 300,000 × 1.159274 = $347,782.
- Balance in five years. Amortising 60 payments leaves $168,500.
- Net sale proceeds. 347,782 × 0.94 − 168,500 = 326,915 − 168,500 = $158,416.
- Total profit. Five years of cash flow (5 × 2,490.54 = $12,453) plus $158,416 of proceeds, less the $84,000 invested = $86,868.
- Total return. 86,868 ÷ 84,000 = 103.4%. Annualised: (1 + 1.034)1/5 − 1 = 2.03410.2 − 1 = 15.26%.
Note that the annualised 15.26% is below the first-year 16.07%, even though the components grow. That is the selling cost: 6% of $347,782 is $20,867, which is nearly a quarter of the total profit and is paid once, at the end. Shorten the hold and it hurts more; lengthen it and the drag spreads.
How to read the split, not just the total
The composition of the return tells you more than its size. Look at which of the three components is doing the work.
Appreciation-dominated returns are assumptions, not results. If the value component is most of your total, you are forecasting rather than measuring. Nothing about a property's operations produces appreciation; it is set by the market, and the same leverage that turned 3% into 10.7% turns a 3% decline into a 10.7% loss. Run the calculator at a negative rate and see what you are actually exposed to.
Paydown-dominated returns are safe but slow. Principal reduction is the most reliable component — it is contractual, it needs no assumption, and it accelerates. It is also illiquid: you cannot spend it without selling or refinancing.
Cash-flow-dominated returns are the resilient ones. Cash flow is what lets you hold through a downturn instead of selling into one. A property that returns 8% with half of it in cash is a stronger position than one that returns 16% with nothing in cash.
Watch return on equity as the hold lengthens. Total gain divided by current equity is a different question from total gain divided by original investment, and it is the one that determines whether you should keep the property. As equity accumulates through paydown and appreciation, the same dollar gain becomes a shrinking percentage of a growing base. When return on equity falls below what that capital could earn redeployed, it is time to look at a cash-out refinance or a 1031 exchange.
First-year return components at different leverage levels
| Down payment | Cash invested | Year-1 paydown | Year-1 appreciation | Appreciation as % of invested |
|---|---|---|---|---|
| 100% ($300,000) | $309,000 | $0 | $9,000 | 2.91% |
| 40% ($120,000) | $129,000 | $2,011 | $9,000 | 6.98% |
| 25% ($75,000) | $84,000 | $2,514 | $9,000 | 10.71% |
| 20% ($60,000) | $69,000 | $2,681 | $9,000 | 13.04% |
Paydown figures are the first-year principal on loans of $0, $180,000, $225,000 and $240,000 at 6.5% over 30 years — each is 1.1171% of the opening balance, since first-year paydown is proportional to loan size at a fixed rate and term. The final column is $9,000 divided by cash invested, and it is also the factor by which a 3% price decline would hit your capital.
Assumptions and limits you should be explicit about
- This is a pre-tax calculation. Depreciation deductions, the tax on rental income, and depreciation recapture at sale are all outside it. For a US investor the first two usually help and the third hurts.
- Appreciation is the assumption that dominates. At default leverage, each percentage point of annual appreciation is 300,000 ÷ 84,000 = 3.57 percentage points of first-year return. Test your result at 0% and at a negative rate before believing it.
- Capital expenditure is not modelled separately. If your cash-flow figure includes a reserve, major replacements are covered; if it does not, a single roof can erase a year of return.
- Cash flow growth is applied uniformly. Real rents step up at renewal while taxes and insurance move on their own schedules, so a smooth growth rate is a simplification.
- The exit assumes a sale, not a refinance or a 1031 exchange. Selling costs are deducted once at the end and they are a large share of the total on a short hold.
- The loan is assumed fixed-rate and fully amortising. Interest-only periods, adjustable rates and balloon maturities all change the paydown component substantially.
Total return, IRR and the metrics this replaces
This calculator sits one level above the single-year ratios and one level below a full discounted cash flow.
Against cash-on-cash return: that ratio is this one with two of the three components deleted. It is more verifiable and much narrower. Use the cash-on-cash return calculator when you want a number built only from things you can check, and this one when you want the whole picture.
Against cap rate: the cap rate ignores your financing entirely and measures a single year of the asset. It cannot see leverage, so it cannot see most of what this page computes.
Against IRR: internal rate of return is the more rigorous version of the annualised figure here, because it discounts each year's cash flow at the point it actually arrives rather than treating the sum as if it landed at the end. When cash flows are uneven — a lease-up year, a refinance, a capital project — the two diverge and IRR is right. The real estate IRR calculator handles those cases. When cash flows are level, the two are close.
One last framing. Property returns are usually quoted in nominal terms while the mortgage is fixed in nominal terms, so inflation quietly transfers value from lender to borrower over a long hold. A 3% appreciation assumption in a 3% inflation environment is a 0% real gain on the asset — but the debt shrinks in real terms at the same 3%, and on a 60% loan-to-value position that is a real gain of 4.5% of your equity every year. That mechanism is invisible in any single-year metric, and it is a large part of why long-held leveraged real estate has behaved the way it has.
