What financial calculators does Texterfly offer?

Texterfly offers 8 free financial calculators: an Ultimate Loan Calculator (with side-by-side comparison and PITI), a Mortgage Calculator, a Compound Interest Calculator, an Amortization Calculator, a Loan Repayment Calculator, an Advanced Cost of Living Calculator (city comparison), an E-commerce Profitability Calculator, and a Carbon Footprint Calculator.

How does compound interest work?

Compound interest means you earn interest not just on your original principal, but also on the interest you have already earned. The formula is A = P(1 + r/n)^(nt), where A is the final amount, P is the principal, r is the annual interest rate (as a decimal), n is the number of times interest is compounded per year, and t is the number of years. The Compound Interest Calculator computes this instantly for any inputs.

What is PITI in a mortgage calculator?

PITI stands for Principal, Interest, Taxes, and Insurance. It represents the full monthly cost of homeownership — not just the loan payment. Principal is the portion reducing your loan balance; Interest is the lender's charge; Taxes are the monthly portion of your annual property tax; Insurance covers homeowner's insurance and, if applicable, PMI (private mortgage insurance). The Mortgage Calculator includes all four components.

What is the difference between the Loan Calculator and the Amortization Calculator?

The Ultimate Loan Calculator is designed for comparing multiple loan options side-by-side and calculating mortgage PITI. The Amortization Calculator focuses on a single loan's full payment schedule month by month, and specifically models how extra payments (monthly, yearly, or one-time) reduce your total interest paid and shorten the loan term.

How do I calculate a monthly loan payment?

The formula for a fixed monthly loan payment is: M = P[r(1+r)^n] / [(1+r)^n − 1], where M is the monthly payment, P is the loan principal, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of payments. For example, a $200,000 loan at 6% annual interest for 30 years: r = 0.005, n = 360, M ≈ $1,199.10.

How do I use the Cost of Living Calculator for relocation?

Enter your current city and salary, then enter the city you are considering moving to. The calculator adjusts for local taxes, housing, food, transport, and lifestyle costs to show your equivalent disposable income in the new city and the salary you would need to maintain your current standard of living.

Can I use the E-commerce Profitability Calculator for Shopify or Etsy?

Yes. The E-commerce Profitability Calculator includes platform fee presets for Shopify, Etsy, Stripe, and others. Enter your product price, cost of goods, shipping, and platform fees to see your true profit margin after all costs — including VAT/sales tax if applicable.

How much does making extra mortgage payments save?

Making extra payments on a mortgage can save tens of thousands of dollars in interest and cut years off the loan. For example, adding $200/month extra to a $300,000, 30-year mortgage at 6% saves approximately $80,000 in interest and pays off the loan about 7 years early. Use the Amortization Calculator to model your specific scenario.

What is a cost of living calculator?

A cost of living calculator helps you compare the total monthly expenses in two different cities — including housing, food, transport, and taxes — so you can understand how much salary you need to maintain the same standard of living after a move.

What is "equivalent salary" in a cost of living comparison?

The equivalent salary is the pre-tax income you need in your destination city to end up with the same monthly disposable income (take-home pay minus expenses) as you have in your current city. It accounts for both cost-of-living differences and local tax rates.

What is disposable income and why does it matter?

Disposable income is your after-tax monthly salary minus all your monthly living expenses. It is the money you have left for savings, investments, or discretionary spending. Two cities may have the same expenses, but different tax rates can significantly change how much money you actually keep.

How do I find my effective tax rate?

Your effective tax rate is your total income tax paid divided by your gross income. You can find it on your last annual tax return, or estimate it using an online income tax calculator for your state or country. It typically combines federal, state, and local taxes.

Does cost of living vary a lot between US cities?

Yes, significantly. For example, the same standard of living that costs $7,000/month in San Francisco might cost only $4,500/month in Austin or $3,800/month in Raleigh. Housing is typically the largest driver, but state income taxes can add thousands of dollars of difference annually.

How does moving to a no-income-tax state affect my salary?

States like Texas, Florida, Nevada, and Washington have no state income tax. Moving from a high-tax state like California (up to 13.3% state tax) or New York can effectively give you a 5–10% salary increase without your employer raising your pay. This calculator factors in the tax rate difference automatically.

What do the lifestyle presets (Budget, Standard, Luxury) mean?

The lifestyle presets automatically fill in groceries, transportation, and discretionary spending as a percentage of your housing cost. Budget applies lower multipliers for frugal spending, Standard uses moderate estimates, and Luxury applies higher multipliers for premium spending. They are starting points you can adjust manually.

Can I save and share my city comparison?

Yes. All your inputs are encoded into the page URL automatically. Click "Share Scenario" to copy a unique link you can send to family, friends, or a recruiter, or bookmark for later. You can also download a PDF or copy a text report.

Is this calculator accurate?

The calculator is as accurate as the data you enter. It uses a mathematically precise formula for equivalent salary and disposable income. For best results, research your destination city expenses on Numbeo, Zillow, or local rental sites, and use a tax calculator for your specific income level.

What currencies does the cost of living calculator support?

The calculator supports USD, EUR, GBP, EGP, CAD, AUD, JPY, and INR. Select your currency from the dropdown and all inputs and outputs will use that currency symbol.

Cost of Living Calculator — Salary, Taxes & Disposable Income

Beyond Expenses: The True Cost of Moving to a New City

Relocating involves far more than comparing rent prices. True financial planning requires understanding your post-tax disposable income — the money you actually keep after both taxes and living expenses. This calculator gives you that clarity by factoring in local income tax rates alongside every major expense category.

The result is an equivalent salary — the pre-tax income you need in your destination city so that your take-home pay covers new expenses and leaves you with the same amount of money left over each month as you have now. This is the correct number to use in salary negotiations with a new employer.

How the Equivalent Salary Is Calculated

The formula used:

Equivalent Salary = (Disposable Income + New City Expenses) ÷ (1 − New Tax Rate) × 12

Where Disposable Income = (Current Salary ÷ 12) × (1 − Current Tax Rate) − Current Monthly Expenses.

This ensures that no matter how different the tax rates or expense levels are, the equivalent salary always leaves you with identical purchasing power.

Why Taxes Change Everything

A city might have lower rent, but if its state income tax rate is significantly higher, you can end up with less money every month. For example:

California (High-Tax)

$100k salary · 35% effective rate · $3,500/mo rent

≈ $2,883/mo disposable

Texas (No State Income Tax)

$85k salary · 22% effective rate · $2,000/mo rent

≈ $3,533/mo disposable

Despite earning $15k less per year and living in a "cheaper" state, the Texas scenario yields $650 more per month in disposable income — because no state income tax and lower costs compound. This is exactly why our calculator includes tax rates, not just expenses.
