Liquidate TFSA to pay off Mortgage or renew at 5.7% 5 yr Fixed?

@squidomerer If I’m understanding this right it’s the opportunity cost of inflating your TFSA over time.

For sake of easy math let’s say my current TFSA of 160k averages 5% every year.

So;

2025: 168k + 7k contribution
2026: 183k + 7k
2027: 200k + 7k

Total room: 207k

3 years from now my TFSA would be 207k if I left the money in the TFSA. Hence contribution room would be 207k the following year if I pulled the entire 207k in 2027.

If I pull all my TFSA out this year, in 2027 my contribution room would be;

2025: 160k + 7k Contribution
2026: 167k + 7k
2027: 174k + 7k

Total room: 181k

So that’s a loss of 26k contribution room over 3 years.

I think this makes sense?
 
@sofarfromfaze You’re misunderstanding the point that was made. By using the funds in the TFSA you are losing EXTRA “contribution room” that would have been created through investment growth.

If you keep your TFSA maxed at 140k and assume a 5% annual rate of return then after year one you will have (140k * 1.05) + 7k (annual cont.) = 154k. You gained an additional 7k in “contribution room”, or money available in your TFSA to grow tax free, because of the 5% return you earned.

If you had withdrawn everything from your TFSA to pay your mortgage, yes, you can pay it back aggressively but that first year you only gain the 7k annual contribution room. You missed out on the additional room created from the growth, which over time, can end up being a substantial benefit. To re-max your TFSA it will likely take a few years.
 
@sofarfromfaze Your wealth grows faster in a TFSA than a non registered account.

If one does no savings in their TFSA, pays off their mortgage first, then saves more money down the road, their TFSA will be significantly smaller, and therefore, they would accumulate more non registered assets.

What the breakeven point depends on expected ROI, average mortgage rates over the 25 year term, and your marginal tax rates.
