Understand cash flow ↗01 / Understand the headline
A central-bank rate, your mortgage rate and a company's cost of capital are connected. They answer different questions.
A central bank influences the cost of money. Changes can affect saving, borrowing and spending across the economy.
What changed in the headline?
A mortgage lender also considers funding costs, loan risk and the length of the deal. Your contract determines when a change reaches you.
When does your own rate change?
A business valuation reflects the timing and risk of future cash flows. Its discount rate is not simply the central-bank rate.
What risk does the rate reflect?
Higher borrowing costs can leave some households with less to spend. They can also make a new business investment harder to justify. These effects can change demand, sales and future cash flows.
Timing matters. A borrower within a fixed-rate period may be insulated until refinancing. A saver may receive more interest, but the return after inflation still matters. People with no borrowing can feel indirect effects through prices or employment.
For a business, separate two channels: changes to its expected cash flows, and changes to the rate used to discount those cash flows. Hold one constant while exploring the other. Avoid treating every rate as if it moves one-for-one with policy.
Try explaining this: two households owe the same amount, but only one is refinancing this year. Why might the same rate headline affect their budgets differently?
Their contract terms and refinancing dates differ. The household refinancing soon faces the available new rate; the household still in a fixed period generally keeps its contracted rate until that period ends.
02 / Bring it home
Change the assumptions to compare two repayment mortgages.
Illustrative example · GBP · not a mortgage quoteChange in monthly payment
+£114more each month at the comparison rate
Bar shows the starting payment as a proportion of the larger payment.
A repayment mortgage with monthly payments, a nominal annual rate divided by 12, no fees and no overpayments. Each rate stays constant for the entire term. Real deals may reset, include fees or use different conventions. This is not an affordability assessment or a rent-versus-buy comparison.
Payment = P × r / [1 − (1 + r)−n], where P is principal, r is the monthly rate and n is the number of monthly payments. At zero interest, payment = P / n. Total interest = payment × n − P. Outputs are rounded for display.
A one-point rise here is an assumption you chose. It does not mean a central-bank rate rise will change every mortgage by that amount.
03 / Follow the money into a business
Follow a fictional manufacturer's revenue into profit, cash flow and value. Then change the assumptions and explain why the answer moves.
