Freelance digital marketer · Websites, digital products & apps
Who runs WebToolsKit
WebToolsKit is built and run by Leena Jadhav under her brand Content Cottage. Leena is a freelance digital marketer with expertise in building websites, digital products and apps. WebToolsKit is one of those projects — a growing collection of free calculators and everyday tools.
What you'll find here
The site has free tools in five sections:
- Finance — EMI, SIP, rent vs buy, salary hike, currency and household budgets
- Health — BMI, ideal weight, body fat, TDEE, water intake, sleep and pregnancy due date
- Freelance — rates, invoices, project profit, notice period and work-from-home costs
- Students — CGPA, attendance, marks needed, study planners and more
- Utility — word counter, QR codes, unit and time zone converters and other everyday helpers
How the tools work
Every tool runs in your web browser. You don't need to sign up, and the numbers and text you type into a calculator are not uploaded or stored. Each tool page explains how its result is calculated, with answers to common questions.
The results are estimates to help you plan. They are not financial, medical, legal or tax advice — please check important decisions with a qualified professional. See our Disclaimer for details.
How the site is funded
WebToolsKit is free to use. To cover its costs, some pages show advertisements and some include Amazon affiliate links, which may earn a small commission at no extra cost to you. Read our Affiliate Disclosure and Privacy Policy to learn more.
