You should take full advantage of tax deferral benefits and contribute up to the annual deferral limit every year, if it fits in your overall financial budget.
Financial planners recommend saving a total of 15% to 20% of gross pay annually toward your retirement goal. If you cannot contribute that much without dipping into expenses, we recommend budgeting to see what discretionary expenses can potentially be cut to get to this goal.
You should contribute the highest amount you can comfortably afford and, if offered, at least enough to take advantage of any employer matching contribution to avoid leaving money on the table. If circumstances change, you can update your contribution rate at any time.
