Retirement Income Gap Calculator
Compare the income you want in retirement with the income you expect, and see the corpus needed to close any gap.
Quick answer
The retirement income gap = desired income inflated to retirement - income sources such as pension and rent - portfolio income at your withdrawal rate. Gap / withdrawal rate gives the extra corpus needed.

Assumptions & method
- Desired income at retirement = desired income × (1 + inflation)^years.
- Source amounts are in today's money and assumed to rise with inflation. Fixed (non-indexed) income should be entered at its lower real value.
- Projected portfolio = current portfolio and monthly savings grown monthly at the nominal return, then divided by (1 + inflation)^years for today's money. Savings are flat in nominal terms and added at month end.
- Portfolio income = projected portfolio (today's money) × withdrawal rate. Gap = desired income − sources − portfolio income.
- Extra corpus needed = gap ÷ withdrawal rate (zero if there is no gap). The rate is your own assumption, not a guaranteed safe figure.
- Taxes, fees, healthcare shocks and market volatility are not included.

Finding the gap between need and income
Planning for retirement means comparing two numbers: the income you will want and the income you can count on. This calculator starts from your desired annual income in today's money, adjusts it for inflation to the retirement date, then subtracts the income sources you list, such as a pension, rent or part-time work. It also estimates what your current portfolio could provide at your chosen withdrawal rate. What remains is the yearly gap, and dividing it by the withdrawal rate gives the extra corpus needed to fill it. All results are estimates.
