Spending Phases

Model realistic retirement spending

Your spending won't stay flat for 30 years. fidser. models the natural decline in spending as you move through retirement phases — from active "Go-Go" years to quieter "No-Go" years.

  • Go-Go years (65-75): Full spending on travel & activities
  • Slow-Go years (75-85): 85% of initial spending
  • No-Go years (85+): 75% as activity decreases
  • More realistic than flat spending assumptions

Retirement Spending Phases

Annual spending adjusted for lifestyle changes

Phased spending
Flat spending

Most calculators assume flat spending — but research shows retirees naturally spend less as they age. fidser. models this reality for more accurate projections.

Spending phase percentages are illustrative examples based on retirement research. Your actual spending patterns may vary. This is for educational purposes only.
