Property investors love talking about equity, capital growth, and portfolio value. But there is one number that cuts through all the theory and tells you whether your actual cash is earning anything: cash-on-cash return.
Cash-on-cash is identical to ROI in most situations. It measures your annual pre-tax cashflow divided by the total cash you have put into the deal. The difference is subtle: ROI sometimes includes non-cash benefits like capital growth. Cash-on-cash is ruthlessly about what hits your bank account.
Here is why it matters. You can own a property that has doubled in value but delivers zero cash-on-cash return. You are equity rich and cashflow poor. That is fine if you plan to sell. It is a problem if you need income.
Cash-on-cash becomes especially important when you use leverage. If you put £50,000 into a BTL that delivers £5,000 a year after mortgage payments, your cash-on-cash is 10%. That is excellent. But if interest rates rise and your mortgage payment goes up by £200 a month, your cashflow drops to £2,600 and your cash-on-cash drops to 5.2%, which is mediocre.
For South Coast property, where prices are high and yields are lower than the north, cash-on-cash returns of 4% to 7% are typical. If you can consistently achieve 8% or more, you are doing well.
Watch out for low-deposit mortgages that boost your cash-on-cash return on paper but leave you with negative equity if prices drop. A high cash-on-cash return with a 10% deposit is more fragile than a moderate return with a 25% deposit.
The formula
CoC (%) = (Annual Pre-Tax Cash Flow / Total Cash Deployed) × 100
Why this matters
Cash-on-cash is the most honest measure of your property’s income performance. It ignores equity and capital growth and asks one question: how much cash did I put in, and how much cash am I getting back? If the answer is disappointing, the property needs to justify itself through growth.
Running these calculations before you buy is the difference between a good investment and an expensive lesson. Xelox Properties can help you evaluate any deal.
