How the calculator works
- Household income and the mortgage you want.
- Your rate and amortization: the qualifying rate is worked out from your rate.
- Property tax, heating and other debts: for the GDS and TDS limits.
Example
On $110,000 of income, a $450,000 mortgage at 4.5% over 25 years:
| Amount | |
|---|---|
| Qualifying rate | 6.5% |
| Payment at your rate | $2,491 |
| Payment at the qualifying rate | $3,014 |
| GDS (limit 39%) | 37.8% |
| TDS (limit 44%) | 41.1% |
