Home Loan Tax Benefit Calculator

What a home loan saves in tax across both sections, and how much of it is wasted. Principal competes with provident fund inside one 80C limit, so the second half of the benefit often does not exist.

Also called: home loan tax saving, housing loan deduction.

Tax year
Tax saved by the home loan
₹86,736

₹86,736 saved this year: ₹2,00,000 of interest under 24(b) and ₹78,000 of principal under 80C. The effective interest rate after tax relief is what makes a home loan cheap.

Computed from the published rates for the tax year you selected, which is not necessarily the current year. A calculation, not tax advice, and it does not know anything about your circumstances beyond the figures entered.

Method and background

This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for India change on a published schedule; the effective date is shown on every rule-based tool.

How this is calculated

Interest is deductible under section 24(b) up to a cap on a self-occupied property, and principal repayment counts towards the section 80C limit. The catch is that 80C is shared: provident fund contributions usually fill most of it before any principal is counted, so the principal benefit is frequently zero even though the loan statement shows it. Both wasted figures are reported for that reason.

Method and limits

What it assumes

  • The old regime, a self-occupied property, and possession taken.

What it deliberately does not model

  • The additional deduction under section 80EE or 80EEA for first-time buyers is not modelled.
  • Joint ownership lets each borrower claim separately, which doubles the caps and is not applied.

Frequently asked questions

Why is my principal saving me nothing?
Because 80C is a single shared limit. If provident fund and insurance already fill it, the principal repayment is counted but nothing is left for it to deduct.
Does a joint loan help?
Substantially. Co-borrowers who are also co-owners can each claim the caps against their own income, which is the single largest lever in this calculation.
