Equivalent Income Calculator

A $70,000 salary in one city and a $70,000 salary in another are rarely the same salary in practice. One can leave you comfortable while the other leaves you short every month, because the headline number hides local prices, taxes, benefits and hours worked. This calculator compares income three ways so a job offer can be judged on what it actually buys: across cities using a cost of living index, after taxes and benefits for a true take-home figure, and as an hourly equivalent so salaried, part-time and hourly offers can be compared fairly. Pick a mode below, keep the pre-filled worked example or replace it with your own figures, and read the result as the raise you need, the pay cut you could accept, or the hourly rate an offer is really worth.

Quick Answer

How to use the equivalent income calculator

Choose one of the three modes at the top of the calculator, enter your figures, then click Calculate. The results stay hidden until you do.

1. Compare cities: enter your current annual salary and the cost of living index for your current city and the target city. The tool shows the salary you would need in the target city for equal purchasing power, plus the raise needed or the pay cut you could accept.
2. After-tax income: enter gross income, the year's total taxes and deductions, and the dollar value of benefits. You get the after-tax equivalent income and the share of gross pay it represents. If you first need the gross figure that produces a target take-home amount, work it through an adjusted income calculator and bring the result back here.
3. Hourly equivalent: enter gross income, taxes and expenses, hours worked per year and benefits value. The tool returns a true hourly rate and the value of a 40-hour week at that rate, which is the fairest way to set a salaried offer next to an hourly or part-time one. For the simple pre-tax conversion in the other direction, the annual income to hourly calculator covers the basic salary-to-rate step.

Every mode starts pre-filled with the worked examples used on this page, so you can press Calculate first, see a complete result, and then replace the numbers with your own.

The three equivalent income formulas

Each mode is one short formula. Nothing else is hidden in the tool, and each result line shows its own working.

Two honest limits follow from those formulas. First, the after-tax and hourly modes add the benefits value you enter to cash income. That is a total-compensation view: it is the right comparison when benefits genuinely replace spending you would otherwise do, and it overstates spendable cash if you count benefits you would never buy. Enter only the value you would actually use. Second, if deductions and expenses exceed gross income, the modes return a negative figure rather than blocking you. That is deliberate: a negative result is a useful warning that the offer does not cover its own costs, not an input error.

Worked examples: all three modes

Each row below is a real run of this calculator with the pre-filled values, so you can reproduce every figure exactly.

Read the city example in negotiation terms: an offer of $45,000 in the index-110 city beats the current $70,000 in the index-180 city, even though it looks like a $25,000 pay cut on paper. An offer of $40,000 there would be a real cut in purchasing power, whatever the recruiter calls it.

Where cost of living indexes come from, and how far to trust them

An index compresses a basket of local prices, usually housing, food, transport, utilities and healthcare, into one number scaled so a baseline sits at 100. Several publishers produce them and they do not agree exactly, because they price different baskets for different household types.

• C2ER Cost of Living Index: a long-running US survey of professional and managerial household costs, published quarterly. It is the data behind many bank and relocation calculators.
• Bureau of Economic Analysis Regional Price Parities: official US state and metro price levels built from government price data. Slower to update, but methodologically the most careful of the public options.
• Numbeo: crowdsourced prices for cities worldwide, useful outside the US and for a quick first pass, but based on contributor reports rather than a fixed survey basket.
• Bureau of Labor Statistics Consumer Price Index: the standard measure of how prices change over time. It is not a city-to-city level comparison, so do not use a CPI figure as a city index.

Whichever source you choose, take both city figures from it, from the same release, and check whether the index includes rent. Some widely used indexes exclude rent, which understates the gap between high-rent and low-rent cities. If housing dominates your budget, compare rents for a specific home you would actually take in each city alongside the index result, and cross-check the size of any raise the move requires with a cost of living raise calculator.

What the city comparison does not capture

The index ratio is a strong first answer and an incomplete final one. Four gaps matter most.

• Income tax: indexes measure prices, not tax bills. A move between a no-income-tax state and a high-tax state can shift take-home pay by several percent in either direction, on top of the price difference. Run both places through the after-tax mode before deciding.
• Your own basket: the index assumes an average household. If you do not drive, a transport-heavy index overstates your costs; if childcare is your biggest bill, a basket that weights it lightly understates them.
• Housing tenure: indexes lean on rental and purchase prices at the survey date. If you already own your home outright, a high housing index may barely touch you.
• One-off moving costs: deposits, moving fees and overlap rent are real money, but they are not part of an annual equivalent salary. Budget them separately rather than loading them into the comparison.

Used with those limits in mind, the equivalent salary is the right anchor for a negotiation or a relocation decision. For a dedicated city-by-city price breakdown with category detail, the cost of living calculator goes deeper on the price side, while this page adds the tax, benefits and hours lenses that a pure price comparison leaves out.

What this calculator covers, and why each part matters

This calculator compares offers on purchasing power and take-home pay, never on the headline salary alone, with three modes in one tool and the negotiation number stated in the result itself.

• City comparison: one transparent ratio you can check. Equivalent salary = current salary × (target index ÷ current index). On a $70,000 salary in a city with a cost index of 180, the equivalent salary in a city with an index of 110 is $42,777.78: you could take a pay cut of $27,222.22 and keep the same purchasing power, because costs are 38.9% lower. Use one index source, one date and one index type for both cities: a ratio built from two different sources is not a comparison.
• After-tax mode: benefits are real pay. The same calculator turns $90,000 gross with $22,000 of taxes and deductions and $8,000 of benefits into $76,000 of after-tax equivalent income. Two offers with the same gross can differ by thousands once health cover and employer pension contributions are counted. The city mode measures prices only and does not include income tax, so run the after-tax mode as well when the two places tax pay differently.
• Hourly mode: hours change everything. $80,000 gross less $20,000 of costs plus $5,000 of benefits over 2,000 hours is $32.50 per hour. The same annual pay spread over more hours is a lower rate, which the hourly mode makes visible.
• The negotiation number, stated in the result. This tool states the raise needed or the pay cut you can accept in the result itself, and the after-tax and hourly modes sit one click away, so the figure can go straight into an offer discussion with Copy or Share. Take that figure into the discussion with the salary negotiation calculator.
