About Interest Subsidy Benefit Calculator

An interest subsidy is worth the difference between the market EMI and the subsidised EMI over the eligible period. Discounting that saving stream at the market rate gives its value in today's money, which is the right figure to compare against alternatives.

Formula

Subsidy value

PV = Σ [PMT(P, r_market, n) - PMT(P, r_subsidy, n)] × (1+r_market)^-t

Frequently Asked Questions

Why discount the benefit?

Because savings arrive over decades. The present value shows what the subsidy is worth as a lump sum today.

Is a subsidy taxable?

Treatment varies — some schemes credit it against principal, others pay it as a grant with its own tax treatment.
