India Toolbox
Practical tools for Indian small businesses that need the answer and the context.
India Toolbox is built for the everyday desk work that keeps a business moving: payroll checks, GST math, quoting, invoicing, seller-fee planning, and the support tasks around them.
Warm, fast, and clear by design. Every important page shows what it is based on, where it stops, and what to open next.
Start with the cluster, not the full directory.
Salary and tax, GST and documents, and seller economics are the parts of the site where clarity saves the most time. Support tools stay available, but they do not lead the homepage.
Salary, tax, and payroll checks
GST, invoices, quotations, and challans
Seller-fee and margin planning before listing
Start by job
The site is organized around the questions people actually have, not just around tool count.
Most-used core tools
Start with the calculators people typically revisit through the year.
Take-Home Salary Calculator
Enter your annual CTC and payroll assumptions to compare monthly take-home under realistic Indian salary scenarios.
Income Tax Calculator
Enter income and deductions to compare old vs new regime tax outcomes before payroll or investment decisions.
EMI Calculator
Enter loan amount, interest rate, and tenure to compare EMI burden against total interest cost.
SIP Calculator
Enter monthly SIP, investment duration, and expected return to compare disciplined investing scenarios over time.
PPF Calculator
Enter contribution amount and period to project PPF growth, total deposited amount, and maturity value.
FD Calculator
Enter deposit amount, rate, and tenure to compare fixed-deposit outcomes before locking money in.
Priority clusters
These are the parts of the site with the strongest user intent and the clearest long-term value.
The highest-priority cluster covers salary, income tax, HRA, TDS, and payroll-style documents. Start with the calculator, then move into the guides when you need the reasoning behind the answer.
This cluster is for GST calculations, invoices, quotations, salary slips, challans, and related business-document tasks. The pages are meant to help with the workflow, not just the arithmetic.
Amazon and Flipkart fee pages are being expanded as a real micro-cluster so sellers can move from fee estimation to margin planning instead of treating the result as a single isolated number.
Browse the main clusters
Start with the sections that define the site, then use the support clusters only when the job is genuinely narrower.
Support clusters: Payments and Utility. These stay available for narrow tasks, but they are not the core ranking spine of the site.
Support workflows worth surfacing
These are the non-core pages that still deserve flagship placement because they support real Indian workflows instead of acting like disposable convenience widgets.
Guides that add context, not filler
Read the guide first when you want the reasoning, comparison, or workflow behind the tool result.

Published tools
Browse the maintained tool library that stays in the core public directory. Utility-only pages stay out of this surface unless they support a stronger workflow.
