Two Incomes to One Income Budget Planner
Going from two incomes to one: your month on one pay, what to cut and how long your savings last.
Two incomes to one by Envelo OneWage: your month on one income, what to cut, and whether your savings carry you through.
Parental leave, studies, a job loss or one of you staying home? When one of two incomes stops or drops for a while, the big question is simple: can we live on one income, and for how long? OneWage answers it with your own numbers.

What it does
What you can do
- Add the income that stays, the income that stops, and what comes in instead – leave pay, a benefit or part-time work
- List your monthly costs, essential or flexible, with what each could be during the change
- See your month now and on one income side by side, and the gap each month
- See what your cuts save, biggest first
- Set when the change starts and how long it lasts (or no end date yet)
- See your savings at the change, what the change needs, whether you are ready – and how much more to put aside each month if you are short
- With no end date: how many months your savings last
- Savings month by month: before, during and after the change, with a chart
- A short plan to print, CSV in and out, backup and restore
Example inside
A made-up couple: 2,900 and 2,700 a month after tax. In 4 months one of them goes on parental leave for 6 months, with leave pay of 800. With cuts of 510 a month, the month on one income is 155 short. Putting aside 1,235 a month until then, they will have 8,440 at the change – the leave needs 930, so they are ready, with 7,510 left after.
