- Principal, Sec 80C
- ₹1,09,707
Year-one interest is ₹2,52,709 from the loan schedule; the deductible amount is shown after the statutory cap.
Old regime

New regime
₹97,500
estimated tax
On these inputs, the new regime appears to save about ₹63,271.
Within the old regime, the home loan reduces your tax by about ₹81,029 this year. The new regime gives no deduction for a self-occupied home loan, so a low headline tax there can still be the better outcome. Confirm your choice with a professional.
How this calculator works
Most tax calculators ask you to type in your home-loan interest. This one takes your loan amount, rate and tenure and works out the first-year interest and principal from the actual amortization schedule (the same tested engine behind our home loan calculator), then applies the tax rules to those figures. Change the loan and the deductions move with it.
The rules it applies (FY 2025-26)
- Section 24(b) — interest: deductible up to ₹2,00,000 a year for a self-occupied home; uncapped for a let-out property, though the house-property loss set off against other income is capped at ₹2,00,000.
- Section 80C — principal: up to ₹1,50,000 a year, shared with your other 80C items.
- New regime: the default regime allows none of these for a self-occupied home; only let-out interest against rental income.
- Joint loan: each co-borrower who is also a co-owner can claim the limits independently on their share — set your share to model this.
What it deliberately leaves out
To stay honest, the tool does not model surcharge (which applies above ₹50 lakh of income), the pre-construction interest split (claimable in five instalments after possession), or every exemption you might have. It estimates the core comparison so you can see the shape of the decision — it is not a filing tool and not tax advice. The exact rules and our sources are on the methodology page, and the key terms are defined in the glossary.
