Grihik Property Calculators: A Complete Guide to Every Tool You Need Before, During, and After a Property Deal

New Delhi, July 29, 2026: Buying, renting, or investing in property in India involves a lot more math than most people expect. Between EMIs, stamp duty, tax benefits, area conversions, and returns, a single property decision can involve a dozen different calculations, each pulling from a different set of rules and rates. Grihik has brought all of these into one place, organized by the stage of the property journey you're in — buying, renting, investing or selling, converting units, and a few extra tools for refinancing, tax, and construction. Here's a full breakdown of Grihik calculators, what it does, and why using them actually makes a difference.
Before You Buy

This section covers the calculators most people reach for first, since they answer the basic question: can I afford this, and what will it cost me?

•    Home Loan EMI Calculator — the most-used tool on the page. It works out your monthly installment based on the loan amount, interest rate, and tenure, so you know exactly what you'll be paying every month before you commit to a loan.
•    Home Affordability Calculator — instead of starting with a property price, this flips the question around and shows you the price range you can comfortably afford based on your income and existing expenses.
•    Down Payment Calculator — most buyers underestimate how much cash they need upfront. This tool tells you exactly how much you need to save before you can even apply for a loan.
•    Loan Eligibility Calculator — banks don't lend based on what you want to borrow, they lend based on what your salary and existing EMIs allow. This calculator gives you a realistic idea of what a lender is likely to approve.
•    Stamp Duty & Registration Calculator — stamp duty rates differ by state and can add a significant amount to your total cost, so this state-wise tool tells you the exact duty and registration charges before you sign anything.
•    Property Tax Calculator — once you own the home, property tax becomes a recurring annual cost. This estimates what you'll owe each year.
•    Home Loan Prepayment Calculator — for those who want to close their loan faster, this shows how much interest you'd save and how much sooner you'd be debt-free by making prepayments.
 

While You Rent

Not everyone is ready to buy, and this section helps renters make sense of their own numbers.
•    Rent vs Buy Calculator — probably the most compared tool on the page, since it lays out the long-term cost of renting against buying, based on your specific situation rather than a generic rule of thumb.
•    Rent Affordability Calculator — helps you land on a rent amount that comfortably fits your monthly income, rather than stretching your budget on a place that looks good on paper.
•    Security Deposit Calculator — rental agreements usually expect a refundable deposit, and this works out what's typically expected for your agreement.

When You Invest or Sell

This is where the numbers get a bit more advanced, aimed at people treating property as an investment rather than just a home.
•    ROI Calculator — estimates the overall return on a rental property investment over time, factoring in both rental income and appreciation.
•    Capital Gains Tax Calculator — when you sell a property, LTCG or STCG tax applies depending on how long you held it. This calculates exactly what you'd owe.
•    Rental Yield Calculator — shows your annual rental return as a percentage of the property's value, a key number for comparing investment properties against each other.
•    Property Appreciation Calculator — projects what your property might be worth in the future, based on an expected annual appreciation rate.
•    Brokerage / Commission Calculator — works out the agent's commission payable on a sale or purchase, so there are no surprises when the deal closes.

 

Area & Unit Converters

Indian real estate uses a confusing mix of measurement units depending on region and property type, and these two tools clear that up.
•    Area Unit Converter — instantly converts between sq ft, sq yard, acre, hectare, gaj, and bigha, which is especially useful since units like bigha vary in size from state to state.
•    Carpet vs Built-up vs Super Built-up Calculator — helps you understand how much space you're actually getting to use inside a flat, since the number developers advertise is usually larger than the real usable area.

Other Tools

A handful of extra calculators round out the page for more specific needs.
•    Mortgage Refinance Calculator — checks how much you could save by switching your existing home loan to a new lender at a lower interest rate.
•    Income Tax Benefit Calculator — calculates the tax savings available under Section 80C and Section 24(b) on your home loan's principal and interest payments.
•    Construction Cost Estimator — for those building on a plot rather than buying ready-made, this estimates the cost based on area and cost per square foot.

 

Why These Calculators Are Actually Efficient

The real value of having all these tools in one place isn't just convenience — it changes how confidently you can make a property decision.
•    They replace manual, error-prone math. Formulas for EMI, stamp duty, or capital gains tax aren't things most people remember correctly, and small errors can lead to big miscalculations in a transaction worth lakhs or crores.
•    They let you compare scenarios instantly. Want to see how a 0.5% rate difference changes your EMI, or how a different tenure affects your total interest? A calculator gives you the answer in seconds instead of requiring you to redo the math by hand each time.
•    They cover the entire property lifecycle. From the first affordability check to the tax owed on a future sale, the same platform supports every stage of a property journey, so you're not jumping between different tools or sources for each calculation.
•    They reduce reliance on assumptions. Instead of trusting a broker's verbal estimate of brokerage, stamp duty, or your loan eligibility, you get an independent number you can verify yourself.
•    They're free and require no sign-up, which means there's no barrier to checking your numbers as many times as you need before making a decision.


Property decisions in India involve more moving parts than most other financial decisions people make in their lifetime — loan terms, state-specific duties, tax rules, area units, and investment returns all come together in a single transaction. Having a full set of calculators covering every stage, from the first affordability check to the tax owed years later on a sale, makes it far easier to plan with real numbers instead of guesswork. As always, treat these calculators as a strong starting point for planning, and confirm final figures with your lender, tax advisor, or legal counsel before signing any documents.
