Estimate amount back on 3 IRP5 2009-2010, 01/2013-28/2/2013 and lastly 2012-2013/02/10

We have a refund calculator which you could use for the 2013 tax year. If you use it for all the years then the refund will be slightly less for prior years as the tax free portion has increased, but still worth trying.
