Large debt low interest v small debt high interest

Hi all,
I have 2 mortgage debts
£139K with initial rate at 1.92% for 3 years and
£33K on a variable rate so about 4.6% currently.
I have some savings which I want to use to pay off one of the debts. I'm unsure whether it's more economical to use my saving and continue to overpay the lower debt now or focus on the large one as my payments will jump a lot when my initial rate expires.
I've tried to calculate this using the mortgage calculators online but they don't factor in when the initial rate expires and a guesstimate of what my new rate in 3 years time could be.
Would appreciate and advice or links to advanced mortgage calculators
Many thanks

The larger mortgage is already costing you more (£7.31/day, as opposed to £4.16/day on the smaller one), so financially it would make better sense to OP that one and get the balance down as much as possible so you lessen your exposure when the deal endsMortgage start: £65,495 (March 2016)

Personally I would pay off the highest interest  or in reality  put the £ into savings at 5% plus and earn a profit.Achieve FIRE/Mortgage Neutrality by mid 2030

cyphex85 said:Thanks for replying. I didn't realise it was already more expensive! How did you figure out the cost of each per day?
£33,000 x 0.046 = £1518 annual interest ÷ 365 = £4.16 daily interest
Your larger mortgage is the more expensive one until you get it down to about £80k, at which point it's £4.20/day in interestMortgage start: £65,495 (March 2016)
