“Comfortable” means covering your needs without stress while still saving — not just scraping by. This calculator sizes a single-person Kansas City budget from local costs (median 1-BR rent near $1,100, plus typical utilities and transit), then uses the 50/30/20 rule to gross it up into the annual pre-tax salary you’d need. For a baseline lifestyle that lands around $52,000.
How it works
The tool builds a monthly needs figure, then back-solves income from the 50% needs allocation:
needs = rent + utilities + transit + groceriesAndOther
monthly comfortable income = needs / 0.50
annual salary = monthly income * 12
A lifestyle multiplier scales the discretionary “wants” cushion, nudging the needs baseline up or down. Because the 50/30/20 rule reserves 30% for wants and 20% for savings, sizing income so needs are exactly half guarantees room for both.
Notes and example
With $1,100 rent, ~$180 utilities, ~$50 transit, and $840 for groceries and other essentials, needs total roughly $2,170/month. Dividing by 0.50 gives about $4,340/month, or **$52,000/year**. Raise the rent or lifestyle level and the target climbs; add a roommate and it drops sharply. These are planning baselines, not guarantees, and they approximate taxes. Everything runs locally; nothing is uploaded.
