Commercial Mortgage Payment Calculator
Enter your commercial mortgage amount, rate and amortization — see payments for principal + interest or interest-only, at any frequency. Amortizations from 5 to 50 years, standard at 25.
Your commercial mortgage
Commercial variable-rate mortgages and HELOCs are typically compounded monthly. Specific lender conventions vary by product and sponsor; confirm compounding directly with the lender.
At the same nominal rate, less-frequent compounding produces a lower payment.
Default 25 years, up to 50. Commercial amortizations vary by asset class and lender. 25 years is the market standard. 30–50 years is possible on multi-family, CMHC MLI Select, and select construction-to-perm files.
Think of the quoted rate as the “sticker” rate. EAR is the real yearly cost after the lender’s compounding schedule is applied. The gap above is the extra cost versus a semi-annual-compounded mortgage at the same sticker rate — the best case any Canadian institutional lender offers. The more often interest compounds, the higher the real cost, even when the sticker rate looks identical. Simple-interest mortgages are not available here, so use this EAR to compare lenders apples-to-apples, not to look for something “better than semi-annual.”
Same payment, every frequency
Time to payoff vs semi-annual compounding
Same total dollars paid per year ($92,164), solved against each compounding schedule.
You're already on the Canadian best-case schedule — semi-annual compounding. No time is lost to a heavier compounding convention at this rate.
Over the full amortization
Computed for your selected payment frequency — accelerated schedules genuinely shorten the totals above. Assumes the same rate for the entire amortization; real mortgages renew every 1–5 years at then-current rates. For the full year-by-year schedule and accelerated payment options, see the Amortization Calculator.
- Lets you choose the interest compounding frequency — and shows the effective annual rate (EAR) gap in basis points versus Canada's semi-annual convention
- Names names: Scotiabank and Strive compound variable semi-annually (the cheapest schedule any institutional lender offers); RBC compounds at payment frequency (the most expensive) — and prices the difference
- Shows time-to-payoff and interest cost versus semi-annual compounding, so 'the same rate' stops hiding different real costs
- True accelerated bi-weekly and weekly schedules that actually shorten your amortization — not just relabelled monthly math
