What “last 28 days” popularity means
This is not a permanent ranking of importance; it reflects recent real usage on Kalkulatori.bg—seasonality, news cycles, and personal finance moments. In 2026, euro transition topics also influence traffic. Use the list as a guided tour if you are new to the site.
1. Fuel cost
Fuel hits household budgets and small-business delivery costs. The fuel cost calculator estimates liters for a route, cost per 100 km, and total trip cost.
2. Calories and TDEE
Nutrition and movement are the second “big axis” after money. Start with the TDEE calculator and read the longer TDEE explainer for theory and examples.
3. Salary
When insurance thresholds or minimum wages change, the salary calculator stays a daily tool for employees and HR—compare gross to net and employer cost before negotiations.
4. Interest
Rates affect both savings and debt. Use deposits, loans, and NAF interest where relevant; see the interest calculators overview.
5. Taxes
VAT is heavily used for invoicing; the tax calculators guide covers a wider set of topics. Direct link: VAT calculator.
