Formula
Months = 12×(retirement age − age); Bnext = B×(1+rate/1200)+deposit
Current savings = 10,000 · Monthly contribution = 200 · Nominal annual return (%) = 5 · Current age = 30 · Retirement age = 65
How to use
- Enter current savings and monthly contribution.
- Set current age, retirement age and nominal return.
- Review projected capital and annual growth.
Examples
- 1000 plus 100/month for one year at 0%: 2200.
- 200/month for five years at 0%: 12000.
