According to the poster, the growth rate is 20% not 5%. Either way, to ball park acquisition price, you can divide growth rate by 10, add 1, then multiply in yearly revenue ((growth% / 10 + 1) * revenue). You can also divide growth rate by 10, double it, then multiply in yearly revenue ((growth% / 10 * 2) * revenue). Those estimates assume profit margins of 30%, so if you want to have it all be a multiple of profit, then divide the multiple by 0.3, then multiply that into yearly profit ((growth% / 10 + 1) / .3 * profit --or-- growth% / 10 * 2 / .3 * profit).
