Built for the financial questions people are actually asking in 2026

CalcHub was created because the most important financial decisions people face today — from navigating tariff-driven price increases to figuring out whether a GLP-1 drug is worth the cost — don't have simple answers. They require real math.

Every calculator on this site was built around a real trend: a search spike, a news cycle, a question millions of people are typing into Google right now. We don't cover every possible calculation — we cover the ones that matter most right now.

All calculators are completely free, require no sign-up, and run entirely in your browser. Your numbers never leave your device.

Finance

Mortgage affordability searches hit an all-time high in 2025 as interest rates stayed elevated. Inflation is quietly erasing the value of raises and savings for millions of households. These calculators put real numbers to those feelings.

AI & Tech

AI API spending grew over 340% year-over-year in 2025. Businesses and developers are struggling to budget for LLM costs. Meanwhile electricity bills are climbing as data centers consume an ever-larger share of the grid.

Health

GLP-1 drugs like Ozempic and Wegovy are the most-discussed medications of the decade. The core question for most people isn't whether they work — it's whether the cost is justified. Our calculator helps answer that with real numbers.

Trade & Tariffs

The 2025 tariff changes were the biggest shift in US trade policy in decades. Businesses importing from China are now facing 145% tariffs. Our import calculator helps businesses and consumers understand exactly what that means for prices.

Insights

2026
Inflation · April 2026

Your raise probably didn't keep up with inflation — here's the math

The US Consumer Price Index rose 2.4% in early 2026, but that number understates what most households are actually experiencing. Grocery prices, insurance premiums, and housing costs have all risen faster than the headline figure. For a household earning $75,000 a year, a 2.4% inflation rate means roughly $1,800 in lost purchasing power annually — even if your salary stayed the same.

The situation is made more complicated by the tariff-driven price increases expected through 2026. Major retailers and consumer goods companies have already announced price increases of 3–8% on imported goods. For households that buy electronics, clothing, or appliances, the effective inflation rate on those categories is significantly higher than 2.4%.

The most important number to know isn't the headline inflation rate — it's your personal inflation rate, which depends on what you actually spend money on. Use our Inflation Impact Calculator to find out whether your raise this year actually put you ahead, kept you even, or left you quietly falling behind.

What 145% tariffs on Chinese goods actually mean for your business

When the US imposed 145% tariffs on Chinese imports in 2025, many business owners assumed it meant prices would roughly double. The reality is more nuanced — and in some cases more painful. The tariff is applied to the declared customs value of goods, which typically includes the cost of the product plus shipping. That means a $5,000 order of goods shipped from China with $400 in freight costs now carries a tariff of roughly $7,830.

For small businesses that built their supply chains around Chinese manufacturing over the past decade, the math has changed dramatically. Many are now exploring alternatives in Vietnam (46% tariff), India (26%), or Mexico (varies by product under USMCA). Each option carries its own cost structure and lead time tradeoffs.
