YTD Earnings Calculator

Your latest payslip shows year-to-date earnings, but turning that into a full financial year figure takes a bit of maths, and that is exactly what this calculator does. It is useful when you want to estimate your total income for the year ahead of a loan application, a budget, or simply to check whether you are on track compared with last year. You enter two things: the date printed on your most recent payslip, and the year-to-date gross income shown on that payslip. The calculator works out where that date sits within the New Zealand financial year, which runs from 1 April to 31 March, including the percentage of the year already remunerated, then uses that proportion to project your extrapolated full financial year gross income. Alongside the headline figure, it shows the workings: the current financial year and its start and end dates, the current financial month, whether it is a leap year, the total days in the year, and how many days have elapsed and remain, both generally and for your payslip date specifically. This lets you follow the logic rather than take the final number on trust. Because the projection scales your YTD figure up at a constant rate, it cannot account for pay rises, bonuses, overtime changes or unpaid leave, so treat the result as an indicative estimate rather than a guaranteed annual income figure.
