Return on investment calculator

Put in what you are investing and what the business earns and spends each month. This works out how many months it takes to get your money back and what that comes to over twelve months.

Your numbers

The boxes start with example figures so the page is never blank. Replace them with yours — the answers change as you type.

The investment

The full amount you are putting in before the business starts earning.

Every month after that

Money coming in from customers in a normal month, before costs.

Everything you spend in that same month — rent, salaries, stock, ads, bills.

What this comes to

  • Payback period

    8.3 months

    Investment divided by profit each month. ₹5,00,000 divided by ₹60,000 a month is 8.3 months.

  • Return over twelve months

    144.0%

    Twelve months of profit divided by the investment. ₹7,20,000 divided by ₹5,00,000 is 144.0%.

  • Profit each month

    ₹60,000

    Monthly revenue minus monthly cost. ₹1,80,000 minus ₹1,20,000 is ₹60,000.

  • Profit over twelve months

    ₹7,20,000

    Profit each month multiplied by twelve. ₹60,000 times 12 is ₹7,20,000.

    This holds your monthly figures steady for a year. Real months move.
