Real Estate Investment Calculator: Definitions & Assumptions
General Assumptions
Mortgage
Based on fixed rate, calculated semi-annually (standard in Canada).
Amortization Period
Number of years it takes to pay off your mortgage. Default: 30 years, unless specified.
Investment Period & Annual Appreciation (%)
Used to calculate your projected returns over time (typically 3–10 years). Market appreciation is applied annually.
Costs
Purchase Price
Price of the property before any renovations.
Renovations
Cost of any planned improvements to boost rent or value.
Closing Costs
Typical costs for Toronto purchases:
Ontario + Toronto Land Transfer Tax
$1,500 for legal/admin fees
Capital Required
= Downpayment + Renovations + Closing Costs
This is your total upfront investment.
Selling Fees
= 4% +HST of selling price.
Income & Cash Flow
Month 1 Rent
Total rent from all units on day one.
Month 1 Operating Expenses
All non-mortgage costs: insurance, property tax, utilities, maintenance, and vacancy buffer.
Month 1 Cash Flow
= Rent – Expenses – Mortgage Payment
Year 1 Cash Flow
= Month 1 Cash Flow × 12
Year 1 Equity Gained
Mortgage principal paid off in the first year—this builds ownership and counts as income.
Year 1 Cap Rate
= (Annual Rent – Expenses) ÷ (Purchase Price + Renovations)
Used to compare income potential across properties.
Year 1 Return Metrics
Year 1 Cash-on-Cash Return
= Year 1 Cash Flow ÷ Capital Required
Tells you how hard your cash is working—just based on monthly profit.
Year 1 Income Return on Capital
= (Year 1 Cash Flow + Year 1 Equity Gained) ÷ Capital Required
Includes both cash flow and mortgage paydown.
Year 1 Total Return on Investment
= (Cash Flow + Equity Gained + Value-Add Appreciation) ÷ Capital Required
Includes rental income, mortgage paydown, and lift from renovations.
Long-Term Projections
Total Cash Flow
Total future cash flow over the full investment period with:
3% annual rent increases
3% annual expense inflation
3% annual general inflation
Total Equity Gained
Total principal repaid over the full investment period.
Total Value-Add Appreciation
Lift in property value after renovations in year 1. Assumed completion value: Purchase Price + (Renovations × 2).
Total Market Appreciation
Value increase over the holding period, minus selling and closing costs.
Total Return ($)
= Total Cash Flow + Total Equity Gain + Total Value-Add Appreciation + Total Market Appreciation – Closing Costs – Selling Fees
Total Return (%)
= Total Return ($) ÷ Capital Required
Annual Return (%)
= {[(Total Return + Capital) ÷ Capital] ^ (1 ÷ Investment Period)} – 1
Your average yearly gain.
Refinancing
Projected Completion Value
= Purchase Price + Renovations + Value-Add Appreciation
Mortgage on Refinancing
= Completion Value × 80% Loan-to-Value (LTV)
Cash-Out on Refinancing
=New Refinance Mortgage – Original Mortgage
Mortgage Payment on Refinancing
Your new monthly mortgage payment after refinancing, based on updated loan terms. Calculated using amortization, interest rate, and new mortgage amount.
Net Capital on Refinancing
= Total Capital – Cash-Out on Refinancing
Monthly Cash Flow on Refinancing
= Operating Income – Refinance Mortgage Payment
