The math component of the UBC Real Estate Licensing Exam can be intimidating. On top of learning new concepts and terms, understanding how to apply them can feel overwhelming.
That is exactly why we decided to publish a fulsome library of UBC Real Estate math lessons for FREE on YouTube. The free video lessons consist of eight videos covering interest, nominal rates, periodic rates, interest rate conversion, types of loans, outstanding balance, and more.

Mortgage Loans and Real Estate Math Fundamentals
This first lesson builds the foundation for UBC real estate exam math by clarifying what a mortgage actually is: not the loan itself, but an interest in a property created by a contract that pledges the property as security for the debt. You'll meet the two parties — the mortgagor (the borrower) and the mortgagee (the lender) — and see why mortgages behave differently from other investments like stocks or bonds: they're illiquid, admin-heavy, capital-intensive, long-term, and unique to each borrower.
The concepts to carry into every later video are amortization (the total time to fully pay off the loan, usually 25–30 years) versus the term (the shorter window your interest rate is locked in). A key takeaway: the term never changes your payment — it only matters for the outstanding balance you map on a timeline. Finally, you'll meet the five calculator variables behind every mortgage question: I/YR, PMT, N, PV, and FV.
Types of Loans and Payment Structures
This lesson covers the types of loans the exam tests and how each one repays. It starts with two simple structures: the interest-accruing loan, where principal and interest are repaid in a single lump sum at the end (so PV grows to a larger FV), and the interest-only loan — like a line of credit — where payments cover interest only and nothing reduces the principal, meaning PV equals FV.
From there it walks through the main mortgage repayment methods: the graduated payment mortgage (payments rise over time), the straight-line principal reduction loan (payments fall), the variable-rate mortgage (payments follow market rates), and the reverse annuity mortgage, where the lender pays the homeowner — often marketed to seniors. Most important is the constant payment mortgage: equal payments split between interest and principal, with the principal portion growing payment after payment. That's the structure behind most UBC real estate exam math questions.
Interest Rates: Nominal, Periodic & Rate Conversions
Interest rates are the lender's rate of return, and this lesson shows how the compounding period changes what a borrower actually owes. A rate is quoted per year but compounded annually, semi-annually, quarterly, monthly, or daily (1, 2, 4, 12, or 365 times) — and the more often it compounds, the more the debt builds on itself.
You'll also learn the two rate types the exam relies on. A nominal rate is a rate per year with a compounding period, often written in J-notation — the J means "per year" and the number is the compounding frequency, so 8% J 2 compounds semi-annually and J 1 is the effective rate. A periodic rate (lowercase i) is simply the nominal rate divided by its compounding period. The first golden rule: always convert to a nominal rate before solving any question.
How to Use the HP 10BII Financial Calculator
Before you can solve a single question, your HP 10BII financial calculator needs to be set up correctly — and these steps work for both the physical calculator and the smartphone app. The lesson tours the keys you'll actually use: the orange shift key that unlocks each key's orange function, RCL (recall) to view saved values, and the core mortgage functions NOM%, P/YR, and AMORT.
The single most important setup step is changing the display to five decimal places (orange shift, then =, then 5) so you round your answers correctly — you only need to do this once. If the calculator ever behaves strangely, reset it with a paper clip in the small hole between the batteries, then redo the decimals. Equally important is knowing what not to press: never switch into BEGIN mode (stay in the default END mode), skip the % key (type 7, not 7%), and leave the blue functions alone.
HP 10BII Practice Questions & Worked Examples
This lesson puts the calculator to work on real exam-style questions using one repeatable system: write out the six variables — P/YR, N, I/YR, PV, PMT, and FV — then fill in the five you're given to solve for the sixth. That's the second golden rule: you need five knowns to find the unknown, and the missing fifth value is usually hidden in the wording of the question.
Along the way you'll lock in what each variable means: N is the total number of payments or compounding periods (years × frequency), I/YR takes the nominal rate with no % key, PV is the opening lump sum, and PMT/FV are the ongoing and ending amounts. Two details save students constant grief: money going out (PMT and FV) must be entered as negative — a "no solution" error usually means a missing negative sign — and every dollar answer is rounded up to the next higher cent. Two worked examples tie it all together.
Payment Frequency and How It Affects Amortization
This lesson tackles what happens when your interest compounding frequency doesn't match your payment frequency — the source of the third golden rule: the compounding periods entered into P/YR must equal the number of payments per year ("interest frequency must match payment frequency"). If there are no payments, or the two already match, you solve normally. When they conflict — say a J2 rate with monthly payments — you first convert to an equivalent rate.
The tool for that conversion is NPEPN, a five-step sequence on the calculator's orange keys (NOM → P/YR → EFF → P/YR → NOM) that translates a rate into the compounding frequency you need. You'll also pick up two exam essentials: in a fully amortized mortgage the FV is always zero, and every payment is rounded up to the next higher cent — a rule that slightly benefits the borrower, who is credited the difference back on the final payment.
How to Calculate Outstanding Balance
The outstanding balance (OSB) is what a borrower still owes on a mortgage at a specific point in time — after payments have chipped away at the principal. This lesson shows that every payment splits between interest and principal: early in the loan most of it goes to interest, and over time more goes toward the principal.
To find the OSB, you solve the question like any other — the six variables, the three golden rules, and NPEPN if the frequencies don't match — to get the payment, then draw a timeline to mark the payment number you're asked about (three years of monthly payments = payment 36). On the calculator you enter the rounded payment, then use the AMORT function (1, INPUT, 36, shift, AMORT) and press equals to cycle through principal paid, interest paid, and the balance (the OSB). The lesson also walks through the same calculation step-by-step in the calculator app.
Full UBC Real Estate Exam Math Review
The final video pulls the whole series together into one UBC real estate exam math review. It revisits the three types of loans — interest-accruing, interest-only, and interest-and-principal (mortgages, where the FV ends at zero) — then recaps the difference between nominal and periodic rates, including how an effective rate or APR is simply a J1 rate.
From there it consolidates the tools you've built across the playlist: the six calculator values (P/YR, N, I/YR, PV, PMT, FV), the three golden rules (use a nominal rate, enter five values to find the sixth, and match interest frequency to payment frequency), the NPEPN conversion for when they don't match, and the AMORT steps for finding outstanding balance, interest, and principal. It's the ideal checklist to run through before exam day — pair it with plenty of practice questions to lock everything in.
