Mortgage guide

£204,000–£229,500

Most lenders work from four to four and a half times gross salary. A real offer depends on your deposit, credit file and outgoings, so treat this as the range to start from.

A 5% pension

£1,894

Paying £2,550 into a pension only reduces your take-home by £1,894, because £656 of it comes out of tax you would otherwise have paid.

Your effective rate on £51,000 is 21.3%, which is what you actually pay across the whole salary. Your marginal rate of 42% is what the next pound costs. People usually quote the second and budget with the first.
