TFSA Contribution Limit Estimator
Estimate future TFSA contribution limits using the official CRA formula based on CPI inflation indexing. See 5-year projections and historical comparisons.
Estimation Parameters
Year to estimate TFSA contribution limit
Used to project CPI for future years. Historical median: 2.2%
Important Notes:
- TFSA limit for year Y is based on PREVIOUS year's CPI (year Y-1)
- Formula: $5,000 × (CPI[Y-1] / CPI[2009]), rounded to nearest $500
- Limits cannot decrease year-over-year (legislative constraint)
- CPI data updated from Bank of Canada
- Future CPI values are projections based on assumed inflation rate
- Government can override the formula (happened once in 2015 with $10,000 limit)
- Official limits announced by CRA typically in late fall for the following year
- This is an educational tool only - not financial advice

About This Calculator
This calculator demonstrates how future Tax-Free Savings Account (TFSA) contribution limits are calculated using the official Canada Revenue Agency (CRA) formula. The TFSA annual contribution limit is determined by taking the $5,000 base amount from 2009, indexing it to the Consumer Price Index (CPI), and rounding to the nearest $500. This calculator uses historical CPI data from Statistics Canada (Table 18-10-0005-01, 2002=100 base year) to show both past actual limits and future projections. The tool reveals why TFSA limits sometimes remain unchanged for multiple years - when CPI inflation doesn't push the indexed amount past the next $500 threshold, the limit stays flat. For example, if the indexed amount is $7,200, it rounds down to $7,000, and it would need to reach $7,250 before rounding up to $7,500. The calculator also identifies historical political overrides, such as the 2015 decision to set the limit at $10,000 instead of the formula-calculated $5,500. Users can project limits for any future year by adjusting the assumed inflation rate, allowing exploration of how different economic scenarios might affect TFSA contribution room. The 5-year projection table shows the step-by-step calculation for each year, including CPI values, indexed amounts, and the final rounded limits.
