The time it takes for first home buyers to save 20 per cent deposit for an entry-level house has risen in the last 12 months, according to date released by Domain.

The Domain First Home Buyers Report, which is based on a couple aged 25-34 years old, found first home buyers of houses in Sydney and Melbourne had to save over six years for a house deposit of 20 per cent, up 2.6 per cent on last year.

That's an extra two months for each capital.

Melbourne prospective buyers of a $600,000 entry level house price would take six years, Sydney six and a half for their entry level price of $680,000.

The biggest jump since the same report last year came in Canberra, closely followed by Hobart.

It would take five and a half years in Canberra for a 20 per cent deposit on a $606,500 house, up 5.6 per cent from last year.

Hobart's surging house prices has seen a 6.4 per cent jump in amount of time needed to save since last year, equating to an extra three months.

An entry level home, now $380,000, would take four years and two months to save for in the Tasmania capital.

Brisbane's entry to buy an apartment is now -4.9 per cent less than it was last year, now three years and three months, with an entry level unit costing $328,000.

Melbourne and Sydney's time to save increased by a month over the year, Sydney now at five years and seven months and Melbourne at four years and three months.
