How to use Retirement calculator
Enter your age, savings, and monthly contribution to see your projected retirement savings and the yearly income they can pay until your chosen age. Everything is shown in today's money as well, so inflation doesn't flatter the numbers.
- Compares your projected income with the income you want and shows any shortfall
- Works out the flat monthly saving needed to close the gap
- Separate investment returns before and during retirement
- Year-by-year balance table
Projections assume steady returns. Real markets go up and down, so treat the result as a planning guide, not a guarantee.
