What lands in your bank account, after income tax and payroll deductions.
Taken from your pay before tax, such as RRSP or 401(k) payroll contributions, pensions and HSA. Savings types count toward your savings rate; your take-home pay above is already net of them.
Money you save or invest out of take-home pay.
Each goal grows at its own rate of return. Use a return after inflation if the target is in today's money.

Coast FI is the point where your investments are large enough to grow into your full retirement number on their own, without further contributions. After that you only need to earn enough to cover today's spending.
Divide the yearly spending your portfolio must cover by your safe withdrawal rate. At a 4% withdrawal rate that is 25 times your annual spending. Pensions and other retirement income reduce the amount you need.
Usually, yes. Accelerated bi-weekly payments add the equivalent of one extra monthly payment each year, all of it going to principal, which can cut years off a 25-year mortgage. Plain bi-weekly payments save very little on their own.
Cash damming is a Canadian strategy where rental income pays down your home mortgage while rental expenses are paid from a HELOC. It gradually converts non-deductible mortgage debt into tax-deductible investment debt. Confirm the setup with a tax professional.
Yes. They come off your pay before tax, so your take-home pay is already lower. Enter them as pre-tax deductions: they count toward your savings rate without being subtracted from take-home pay a second time.
