How is building depreciation calculated in Kerala?

This calculator applies straight-line depreciation at 1.5% per year, capped at 75%. These are KFirst defaults, not statutory rates. The Kerala Stamp Act does not prescribe them; the applicable rules have not been obtained. Confirm with your Sub Registrar.

Is this valuation certificate valid for SBI or other bank loans?

This tool generates certificates following the Section 28-C format for property registration estimation. For high-value transactions, banks or registration authorities may require certification from an empaneled valuer.

What CPWD rates should I use for valuation?

This tool uses working plinth area rates (RCC Residential: ₹2,340/sq.ft, Load Bearing: ₹1,890/sq.ft, Commercial: ₹2,650/sq.ft). The exact active CPWD schedule and edition remain unverified; verify applicable rates with local registration officials.

Is this tool free and secure?

Yes, K-First Valuation Tool is 100% free, requires no login, and processes all data locally on your device. Your property details never leave your browser. The generated PDF has no watermarks and is ready for direct use.

About This Tool

Property Valuation Formulas

Gross Building Value

Plinth Area × CPWD Rate

Total replacement cost before any depreciation.

Where: Plinth Area = Built-up area in sq.ft, CPWD Rate = Current year CPWD plinth area rate (₹/sq.ft)

Depreciation Amount

Gross Value × (Age × 1.5%)

Reduction in value based on building age using Straight Line Method at 1.5% per year.

Where: Gross Value = Total replacement cost, Age = Building age in years, 1.5% = Default annual depreciation rate used by this calculator. Provenance under verification; not established by the Kerala Stamp Act.

Maximum Depreciation Cap

Depreciation ≤ 75% of Gross Value

Total depreciation is capped at 75% regardless of building age. Buildings over 50 years still retain 25% value.

Where: 75% = Default maximum depreciation used by this calculator. Not a statutory cap.

Net Depreciated Value

Gross Value - Depreciation

Final building value after applying capped depreciation.

Where: Gross Value = Total replacement cost, Depreciation = Min(Age × 1.5%, 75%) × Gross Value

Worked Examples

Calculate Valuation for 10-Year-Old House

1000 sq.ft RCC residential building constructed in 2016

Calculate Gross Building Value

1000 sq.ft × ₹2,340/sq.ft = ₹23,40,000

Calculate depreciation percentage

10 years × 1.5% = 15% depreciation

Check against 75% cap

15% < 75%, so we use 15%

Calculate depreciation amount

₹23,40,000 × 15% = ₹3,51,000

Calculate net value

₹23,40,000 - ₹3,51,000 = ₹19,89,000

Result: ₹19,89,000 (Net Depreciated Value)

Calculate Valuation for 60-Year-Old Building (Max Depreciation)

800 sq.ft load bearing structure showing maximum depreciation cap

Calculate Gross Building Value

800 sq.ft × ₹1,890/sq.ft = ₹15,12,000

Calculate raw depreciation

60 years × 1.5% = 90% (exceeds cap!)

Apply 75% maximum cap

Capped at 75% depreciation

Calculate capped depreciation amount

₹15,12,000 × 75% = ₹11,34,000

Calculate net value

₹15,12,000 - ₹11,34,000 = ₹3,78,000

Result: ₹3,78,000 (Minimum 25% retained)

⚠️

For high-value bank loans (typically > ₹50L), banks may require certification from an approved valuer. This tool provides estimates in the official format.
