Understanding the calculator

Estimate your society maintenance in minutes. Designed for small housing societies and self-managed apartment associations.

What it does

This calculator splits your annual budget across flats. You get maintenance per period (monthly, quarterly, yearly) for each flat owner.

Payment frequency

Choose how often you collect maintenance: monthly, quarterly, or yearly. The calculator shows both period and annual amounts.

Your expenses

Add each budget item: insurance, lift maintenance, electricity, water, security. One line per expense, annual amount.

Corpus fund

Set aside funds for future major works. Most committees target 8–15% of operating expenses. Toggle on to include.

For a special assessment, add it as a temporary expense line.

Allocation method

Two options: equal per flat or by ownership shares/area. With shares, flats with higher percentages pay more.

Results and export

See per-flat maintenance instantly. Download the CSV to share with your managing committee or flat owners.

Planning tool only. Always verify final amounts with your managing committee before communicating to flat owners.

Frequently Asked Questions

A few common questions about how to use this maintenance charges calculator.

No. This calculator is for planning and educational purposes only. Your society bylaws, state law (Apartment Ownership Acts), and any decisions voted by your flat owners always take precedence over the results shown here.

This calculator focuses on your recurring annual budget (insurance, utilities, gardening, lift maintenance, etc.). For a large one-time project, add a temporary expense line for this year or run a separate calculation to see how much each flat needs to contribute to the assessment.

Yes. Set the payment frequency to monthly, quarterly, or yearly and the maintenance per period will update automatically. The export keeps both the annual maintenance and the per-period amount so you can communicate charges on whichever cadence your society uses.

Yes. It works for any small apartment association that needs to split an annual budget between flats: housing societies, apartment associations, and some co-operative housing societies. The only requirement is that you either treat all flats equally or have a share/percentage/area for each flat.

You don't need a perfect budget to start. A simple estimate based on last year's maintenance bills plus a reasonable corpus fund contribution is already useful. You can refine the numbers later as you get a better view of your real costs.

Most small housing societies review their budget at least once a year, usually before the Annual General Meeting (AGM). If your costs are changing quickly (insurance, utilities, repairs), it can be helpful to run this calculator more often to see whether your maintenance charges still make sense.
