A lender offers you 0.85% per month on a bridging loan. Another offers 9.5% per year. Which is cheaper? You cannot tell unless you convert them to a common standard. That is what APR does.
APR converts any interest rate to an annual percentage that accounts for compounding. For bridging loans quoted at a monthly rate, the APR is calculated by taking 1 plus the monthly rate, raising it to the power of 12, subtracting 1, and multiplying by 100.
A bridging loan at 0.85% per month has an APR of roughly 10.7%. A loan at 9.5% per year has an APR of 9.5%. Despite sounding similar, they are different products. The APR lets you compare them directly.
APR matters most for short-term finance where rates are quoted in different ways. A bridging lender quoting 0.89% monthly might advertise APR, a hard money lender quoting 12% annual might not. You need the APR to know which is actually cheaper.
For standard mortgages, APR is less important because rates are already annual. But for bridging, development finance, and private lending, APR is essential. Always ask for the APR before you compare quotes.
The formula
APR = ((1 + Monthly Rate)^12 - 1) × 100
Why this matters
APR converts monthly and annual rates to a common standard. Use it to compare bridging loans, development finance, and private lending quotes. If a lender will not give you the APR, be suspicious.
