Balance Projection
This calculator adjusts your baseline annual spending by a city-specific composite cost-of-living index. The composite is a weighted average of six categories: housing (35%), food and groceries (15%), healthcare (15%), transportation (10%), utilities (10%), and taxes (15%). Each category index is relative to the US national average, where 1.0 means average cost.
The balance projection uses your adjusted annual spending and a real return rate (nominal return minus inflation) to model year-by-year portfolio drawdown. Under the fixed strategy, your withdrawal amount stays constant in real terms. Under the flexible strategy, you withdraw a fixed percentage of your current balance each year.
When comparing cities, each line in the projection chart represents one city's trajectory. The category breakdown chart shows where the cost differences actually lie — useful for identifying whether a city's high cost is driven by housing, taxes, or another factor.

Our COL indices are compiled from public sources including the Bureau of Labor Statistics Consumer Expenditure Survey, the Council for Community and Economic Research (C2ER), and Numbeo's crowdsourced data for international cities. Each city's index is relative to the US national average (1.0). We weight six categories — housing (35%), food (15%), healthcare (15%), transportation (10%), utilities (10%), and taxes (15%) — to produce a composite score.
Each category index represents how much more or less expensive that category is compared to the US national average. A housing index of 1.5 means housing costs 50% more than average. The composite index is a weighted average of all six categories, with housing weighted most heavily at 35% because it is typically the largest retirement expense.
Yes. The taxes category uses each state's effective income tax rate relative to the national average. States with no income tax (Texas, Florida, Tennessee, Nevada, etc.) show a 0.0 tax index. For international cities, the tax index represents a general estimate of the tax burden on retirement income rather than a precise rate.
International COL indices are approximate and assume you are spending in local currency at current exchange rates. They do not account for currency fluctuation risk, visa costs, international health insurance, or country-specific tax treaties. Use them as directional guidance, not exact budget figures. For detailed expat retirement planning, consult a cross-border financial advisor.
A fixed withdrawal strategy takes the same inflation-adjusted dollar amount each year regardless of portfolio performance. This provides stable income but risks portfolio depletion in bad markets. A flexible strategy withdraws a fixed percentage of your current portfolio balance each year. Your income varies with the market, but the portfolio theoretically never reaches zero.
The COL dataset is reviewed and updated periodically as new BLS and C2ER data becomes available. Because relative cost differences between cities change slowly, the indices remain useful for planning purposes even between updates. The calculator's methodology and projections are not affected by data freshness.
