What does a late sale cost you?

See what a late exchange or completion, or a sale that falls through, costs you in loan interest. Put in your own figures: nothing you type leaves your screen.

No extra interest yetOn an off-plan home, completion waits for the build, so a late exchange doesn't add interest while the build carries on. But until exchange the buyer isn't committed, and can still walk away. If they do, choose "Sale falls through" to see that cost.

An estimate: lenders work out interest in different ways. Not financial advice. Read the disclaimer

Sales slip for small reasons: a legal enquiry nobody chased, or a mortgage offer about to run out.

PlotBot chases each step of every sale and shows you what's late the day it happens.

Disclaimer

This calculator gives a rough estimate, for illustration only. It uses the figures you put in and simple daily interest, and it doesn't know your loan's actual terms: how your lender charges or adds interest, fees, minimum interest periods, or what happens at the loan's end date. The example figures are illustrations, not typical or average figures. It isn't financial, lending, tax or legal advice. Your loan agreement and your lender decide what you actually pay, so check with them or your own adviser before you make any decision. PlotBot Ltd isn't responsible for any decision made, or loss suffered, from relying on this calculator.
