Designing a budget around irregular income.

A fixed monthly budget starts with a number you already know. Portioned needed to remain useful when the next amount, and the day it will arrive, are both uncertain.

The wrong starting point

Most budgeting advice begins with monthly income. Write down what comes in, list fixed expenses, decide what remains and distribute it. That structure is familiar because it matches a regular salary.

Irregular income changes the order of the problem. There may be no reliable monthly figure to enter at the beginning. The next payment might be larger or smaller than the last, and it may arrive earlier or later than expected. A plan based on a forecast can become obsolete before the month has properly begun.

Design around the moment money arrives

Instead of asking a person to predict the month, Portioned begins with an event that has actually happened: income arrived. The user records the amount, chooses the profile it belongs to and applies a percentage plan.

That shift may look small, but it changes the product. The central action is no longer maintaining a perfect monthly forecast. It is making one consistent decision each time money comes in.

Percentages preserve priorities

Fixed figures can become impossible when income changes. Percentages are more flexible. A portion can represent living costs, taxes, business operations, giving or a personal goal. The value changes with each payment, while the intended priority remains visible.

This does not remove every difficult decision. It gives those decisions a structure. If the split no longer reflects reality, it can be adjusted deliberately instead of allowing spending to decide by accident.

Profiles keep context intact

Not every payment belongs to the same part of life. Personal income, freelance work, a small business and a side project may each need different portions. Portioned uses profiles so those contexts can stay separate without forcing the user to manage unrelated systems.

Currencies remain separate for the same reason. Adding naira, dollars, pounds and euros into one number would create an impressive-looking total that says very little. Clarity sometimes means refusing to combine things that are not meaningfully comparable.

The interface must answer ordinary questions

The product needs to make several answers easy to find: what came in, what was spent, what remains, which portion changed and what is still owed. Those answers matter more than decorative charts or complicated financial language.

That principle is shaping the overview, the activity record and the way individual portions are displayed. Each screen should reduce the effort required to understand the current position.

What I am testing next

The next stage is not only whether the calculations work. It is whether the model feels natural to people with different income patterns. The language, sequence of actions and visibility of balances all need to make sense without a long explanation.

The goal is not to make irregular income behave like a salary. It is to build a planning system that respects how the money actually arrives.
